    Forecasts for Ireland



    Be aware that forecast models are showing potential for strong or even severe winds on Monday, but details remain very uncertain. As of this morning, only one model (GFS) is showing an intense system, others are more moderate. The source of this possible storm is energy now crossing the Great Lakes region in advance of much colder air for that region and this is expected to create a rather small but compact storm off the New England coast by Thursday. After that, this energy could just be absorbed into larger systems with only moderate results, or it could eventually set off a stronger storm as the GFS model has been advertising for several days now. I don't expect much clarity on this until perhaps Thursday.

    TODAY ... Further bursts of heavy rain with slight risk of thunder, in parts of the southeast this morning and then across Munster into most other regions from late morning on, and very mild, with highs around 15-16 C. Rainfall potential 15-30 mm. Another band of heavy rain will approach the northwest by evening to follow on behind remnants of the mid-day batch by then into Ulster and Leinster.Winds southeast veering south to southwest 30-50 km/hr.

    TONIGHT ... Further heavy showers, risk of some thunder, winds moderate from southwest at 30-50 km/hr, 10-20 mm rain, and lows 8-10 C.

    WEDNESDAY ... Showers, still heavy in Leinster and east Ulster during the morning, otherwise more isolated with some sunny intervals developing, not quite as mild with highs 11-15 C coolest in Connacht and west Ulster. Further rainfalls of about 5-10 mm east mainly as a clearing trend develops with just isolated showers in fresh southwest to west winds of 35-55 km/hr with some higher gusts to 75 km/hr near west coast.

    THURSDAY ... Some sunshine to start, increasing cloud, morning lows 4-8 C for most, possibly near 2 C in the usual frost hollows where a grass frost may develop briefly, but as mild as 10 C south coast, then highs 12-16 C. Rain may arrive in west Munster before evening, then will spread to other regions overnight.

    FRIDAY ... Rain will be heavy at times and possibly thundery in places, with a cool east wind for Ulster until late in the day (highs there near 10 C) but otherwise another warm and muggy day will develop in the south and then east-central counties, highs 14-17 C. Winds becoming southerly 30-50 km/hr. Parts of Connacht and west Ulster may remain closer to 10-12 C in east to northeast winds as low pressure tracks through west-central counties or up the west coast. Rainfalls 10-20 mm west, 3-7 mm east where rain less persistent and possibly not arriving until well after mid-day.

    SATURDAY ... Breezy, showers or periods of rain redeveloping, lows 5-7 C and highs 12-15 C. Winds WSW 30-50 km/hr and rainfalls 5-10 mm.

    SUNDAY ... Partly cloudy, showers and possible stronger winds at times by evening or overnight into Monday. Highs near 13 C.

    MONDAY ... Possible strong winds, but definitely breezy at the least, and unsettled. Watch for updates as we monitor risk of more severe winds that could affect all regions depending on track. Highs most likely 11-14 C.

    FURTHER OUTLOOK ... It will likely remain unsettled and highs will continue to hover in the low teens, possibly reaching about 15 C on one or two occasions later in the week as the storm track returns further north.


    Forecasts for Britain

    TODAY .... Rain, heavy at times, with some embedded thunder later in the day. Some rainfalls of 20-30 mm. Very mild and misty or foggy, highs near 16 or 17 C. Winds moderate southerly with stronger gusts near exposed coasts.

    TONIGHT ... Rain continuing heavy at times, very mild, lows 12-14 C.

    OUTLOOK ... From tomorrow on, expect a similar trend to Ireland although events will tend to occur about 6-9 hours later on average, so that for example Wednesday will not tend to clear up in most regions until afternoon or evening, and Friday could remain dry in eastern and central regions.


    Forecasts for North America

    Over the next 2-3 days, a major change will develop in the northeast U.S. with much colder air arriving and some rain or sleet turning to snow especially over higher ground and in some lake effect snow belts. Winds not overly strong but veering more to northwest over time. Highs about 12-15 C today will fall off to 7-10 C tomorrow and 3-7 C on Thursday with some sharp frosts developing by Friday. This colder air is currently sliding south into central Canada behind a weak system moving southeast from North Dakota towards Iowa with rain turning to snow along its track, only a few centimetres likely with melting on roads as temperatures will be about 2-5 C. Meanwhile, the warm and dry pattern further west is being pinched slightly from east to west as winds turn more northerly in Alberta and Montana, warmest readings will now be found in valleys of BC, eastern WA and southern ID where fog lifts during the day. Persistent fog in some valleys and near west coast will hold temperatures down to about 12 C but in sunshine it could soar to 21-23 C.

    My local weather on Monday was foggy with some afternoon sunshine and a high near 14 C.

    Forecasts for Ireland



    TODAY ... Showers soon clearing away from north Leinster and east Ulster, clearing skies for most with just a few isolated showers mainly in northern counties ... some sunny intervals developing, not quite as mild with highs 11-15 C coolest in Connacht and west Ulster. Further rainfalls of about 2-5 mm (northeast mainly) in fresh westerly winds of 35-55 km/hr with some higher gusts to 75 km/hr near west coast.

    TONIGHT ... Some clear intervals, rather widespread higher cloud and some patchy low cloud, lows generally 3-6 C but near the freezing point in a few inland valleys, while staying closer to 8-10 C south coast. Winds becoming calm inland. Some fog patches developing before dawn.

    THURSDAY ... Some sunshine to start, increasing cloud, highs 12-16 C. Rain may arrive in west Munster before evening, then will spread to other regions overnight. Winds rapidly increasing to SE 35-55 km/hr near south and west coast but a slower increase elsewhere. Rain overnight for west (10-15 mm).

    FRIDAY ... Rain will be heavy at times and possibly thundery in places, with a cool east wind for Ulster until late in the day (highs there near 10 C) but otherwise another mild but muggy day will develop in the south and then east-central counties, highs 13-16 C. Winds becoming southerly 30-50 km/hr. Parts of Connacht and west Ulster may remain closer to 10-12 C in east to northeast winds as low pressure tracks through west-central counties or up the west coast. Rainfalls 10-20 mm west, 3-7 mm east where rain less persistent and possibly not arriving until well after mid-day.

    SATURDAY ... Breezy, showers or periods of rain redeveloping, lows 5-7 C and highs 12-15 C. Winds WSW 30-50 km/hr and rainfalls 5-10 mm.

    SUNDAY ... Partly cloudy, showers and possible stronger winds at times by evening or overnight into Monday. Highs near 13 C. The current model consensus is that the strongest winds will arrive either Sunday night or early Monday morning and may be confined to the south, but this continues to evolve and we could be amending this again as models seem to be struggling a bit to resolve this system.

    MONDAY ... Possible strong winds, but definitely breezy at the least, and unsettled. Highs most likely 11-14 C. Some chance of a colder spell (lows could dip to near or even slightly below freezing Tuesday morning in some places as winds turn more northwesterly) although not all that severe, slight risk of hail but little chance of snow and that only on high summits, then once again rapidly replaced by milder conditions by mid-day Tuesday again if it happens.

    FURTHER OUTLOOK ... After that possible brief colder interlude, it will likely remain unsettled and highs will continue to hover in the low teens, possibly reaching about 15 C on one or two occasions later in the week as the storm track returns further north.

    Check the forecast from yesterday for information related to Britain and North America as those have not significantly changed today. My local weather was also the same, morning fog and afternoon sun, high of 14 C.

    Forecasts for Ireland



    TODAY ... Some sunshine to start in parts of east and north, increasing cloud with a few outbreaks of rain in the south, highs 12-16 C. Winds rapidly increasing to SE 35-55 km/hr near south and west coast but a slower increase elsewhere.

    TONIGHT ... Rain overnight spreading to most regions, 10-15 mm likely. Lows about 7-10 C. Winds moderate southeast 30-50 km/hr and some dense fog forming especially thick inland south and east.

    FRIDAY ... Rain will be heavy at times and possibly thundery in places, with a cool east wind for Ulster until late in the day (highs there near 10 C) but otherwise another mild but muggy day will develop in the south and then east-central counties, highs 13-16 C. Winds becoming southerly 30-50 km/hr. ... Rainfalls 10-20 mm now seem likely to spread across most regions with a showery trend later in the day in west Munster.

    SATURDAY ... Breezy, showers or periods of rain redeveloping, lows 5-7 C and highs 12-15 C. Winds WSW 30-50 km/hr and rainfalls 5-15 mm.

    SUNDAY ... Partly cloudy, showers (5-10 mm) and stronger winds developing mid-day and afternoon (WSW 50-80 km/hr) with lows 7-9 C and highs about 13 or 14 C. Slight risk of stronger gusts in some coastal regions.

    MONDAY ... Strong winds may abate for a time during the early morning hours, but then will redevelop from the west to northwest by morning or mid-day. Skies could clear briefly, then further showers are likely. Morning lows 3-5 C and afternoon highs 9-12 C but feeling quite cold in strong winds. Risk of hail showers in west and north by afternoon, longer dry spells and sunny intervals in south and east.

    FURTHER OUTLOOK ... After a rather cold start to Tuesday with lows 1-3 C, it will likely return to an unsettled and mild pattern rather quickly, and highs will continue to hover in the low teens, possibly reaching about 15 C on one or two occasions later in the week as the storm track returns further north. This mild and breezy pattern seems likely to continue for a good part of November too.


    Forecasts for Britain

    TODAY ... A few sunny intervals may develop despite considerable cloud, isolated showers, mild, highs 11-14 C.

    FRIDAY-SATURDAY ... Mild, breezy, showers or periods of rain at times, highs about 14-16 C.

    SUNDAY-MONDAY ... Windy at times, and risk of a spell of very strong southwest gales in southeast England on Monday with gusts to 110 km/hr. Highs generally 10-12 C.

    OUTLOOK ... Somewhat colder late Monday and Tuesday but then back to a mild and unsettled pattern with occasional strong winds.


    Forecasts for North America

    Much colder air continues to spread further east and south in the eastern half of the U.S. and much of Canada, sleet or snow showers in parts of the lower Great Lakes enhanced by lake effect, but it remains warm and dry on the west coast and some distance inland, with fog less of a widespread factor as the inversion breaks down, allowing more places to escape fog and enjoy mild to warm sunshine. My local weather on Wednesday was sunny and warm with a high of 18 C.

    Forecasts for Ireland


    TODAY ... Rain will be heavy at times and possibly thundery in places, with one band gradually moving across the north this morning, followed by a second band of showers or heavier rain spreading northeast this afternoon. In between there could be several hours of pleasant, very mild conditions with a few breaks in the overcast and highs of 15-17 C. The rainfall bands will bring totals of 15-30 mm (some of which has already fallen in most places). Winds becoming moderate southerly 30-50 km/hr.

    TONIGHT ... Rain finally ending with some clearing for a time in the west, staying rather mild with lows 6-9 C.

    SATURDAY ... Breezy, showers or periods of rain redeveloping from around sunrise in the west to mid-morning east, lows 5-7 C and highs 12-15 C. Winds WSW 30-50 km/hr and rainfalls 5-15 mm. There could be some improvement later afternoon in the west.

    SUNDAY ... Partly cloudy, showers (5-10 mm) and stronger winds developing from early morning in Donegal and morning across Connacht and rest of Ulster, mid-day and early afternoon elsewhere (WSW 50-80 km/hr) with lows 7-9 C and highs about 13 or 14 C. Slight risk of stronger gusts in some coastal regions. A secondary low that will bring very strong winds to southern England will likely miss Ireland to the south but the Wexford coast could feel some strong northerly gusts just after it hits land in Cornwall around 0500h Monday morning.

    MONDAY ... Strong winds will probably abate for a time during the early morning hours except near the south coast possibly, but then will redevelop from the west to northwest by morning across most regions with gusts to perhaps 70-80 km/hr. Except for some rain across the south coast early morning, skies could clear briefly in the morning, then further showers are likely in the windy conditions later. Morning lows 3-5 C except 7-9 C south, and afternoon highs 9-12 C but feeling quite cold in strong winds. Risk of hail showers in west and north by afternoon, longer dry spells and sunny intervals in south and east.

    FURTHER OUTLOOK ... After a rather cold start to Tuesday with lows 1-3 C, it will likely return to an unsettled and mild pattern rather quickly, and highs will continue to hover in the low teens, possibly reaching about 15 C on one or two occasions later in the week as the storm track returns further north. This mild and breezy pattern seems likely to continue for a good part of November too.


    Forecasts for Britain

    TODAY and TONIGHT ... Very mild with outbreaks of rain, heavy at times, but also a few breaks more frequent in southeast England, highs 15-18 C. Overnight lows very mild, 10-13 C.

    SATURDAY ... Mild, breezy, some clear intervals developing briefly then followed by more showers or periods of rain at times, heavier in western districts and across most of Scotland, with highs about 14-16 C.

    SUNDAY-MONDAY ... Windy at times, and risk of a spell of very strong southwest gales in southern England on Monday with gusts to 110 km/hr. Highs generally 10-12 C but 14 C near Channel. These very strong winds will also affect northern France and ferry sailings may be delayed or cancelled.

    OUTLOOK ... Somewhat colder late Monday and Tuesday but then back to a mild and unsettled pattern with occasional strong winds.


    Forecasts for North America

    Continued rather cold in the eastern U.S. and much of eastern-central Canada, but somewhat milder in parts of the plains states and Midwest where highs could return to normal values near 15 C. Another cold push will follow for the weekend but it won't be as cold as the past few days. The west remains largely warm and dry but the western prairies will begin to turn much colder later today as winds veer from west to north, temperatures will drop from mid-teens to near freezing with snow flurries possible. This will only be a glancing blow in regions west of the Rockies and temperatures will fall more gradually there. It should remain warm and dry in the far western U.S. ... My local weather on Thursday was once again sunny and very pleasant at 16 C.

    SUNDAY NIGHT ... A secondary low that will bring very strong winds to southern England will likely miss Ireland to the south but the southeast coast could feel some strong northerly gusts to 80 km/hr just after it hits land in Cornwall around 0500h Monday morning. A band of moderate to heavy rain will bring 20-30 mm rainfalls and risk of spot flooding in southern counties. Winds mainly backing to northeast at around 20-40 km/hr during this phase. Further north, patchy light rain in moderate N to NW winds, lows 6-8 C except 10-12 C southeast.

    MONDAY ... Strong winds will probably abate for a time during the early morning hours except near the south coast possibly, but then will redevelop from the west to northwest by morning across most regions with gusts to perhaps 70-90 km/hr. Except for some rain across the south coast early morning, skies could clear briefly in the morning, then further showers are likely in the windy conditions later. Morning lows 6-8 C except 10-12 C southeast, and afternoon highs 9-12 C but feeling quite cold in strong winds. Risk of hail showers in west and north by afternoon, longer dry spells and sunny intervals in south and east.

    FURTHER OUTLOOK ... After a rather cold start to Tuesday with lows 1-3 C, it will likely return to an unsettled and mild pattern rather quickly, and highs will continue to hover in the low teens, possibly reaching about 15 C on one or two occasions later in the week as the storm track returns further north. The 31st may be quite windy and wet at times. This mild and breezy pattern seems likely to continue for a good part of November too. My long-range forecast calls for a mean temperature of about 7 C in November, slightly above normal.


    Forecasts for Britain

    SUNDAY-MONDAY ... Windy at times, and risk of a spell of very strong to severe and damaging southwest gales in southern England on Monday with gusts to 140 km/hr. Highs generally 10-12 C but 14 C near Channel. These very strong winds will also affect northern France and ferry sailings may be delayed or cancelled. Much less windy north of Bristol to Luton to Norwich although winds increasing in Midlands by late afternoon and evening from WNW 50-80 km/hr as they subside to 60-100 km/hr across the south.

    OUTLOOK ... Somewhat colder late Monday and Tuesday but then back to a mild and unsettled pattern with occasional strong winds.


    Forecasts for North America

    Much colder today in western Canada behind a cold front advancing gradually south into the northern tier of western states. Some snow likely in foothills of Alberta, Montana, 5-15 cm locally. Freezing drizzle mixed in will make this rather treacherous for driving. Also turning cooler on west coast although in the 7-10 C range with drizzle. Some icy stretches on higher sections of mountain highways. Remaining warm and dry in southwest U.S. and this will try to spread northeast although highs will only reach normal values in Midwest (12-16 C). Staying cloudy and cool in the northeast U.S., outbreaks of light rain in places, highs 10-13 C. Sunny and mild in the southeast with highs about 20 C. My local weather on Friday was cloudy with spots of drizzle, light fog and 11-12 C.

    TONIGHT ... A secondary low that will bring very strong winds to southern England will likely just miss Ireland to the south but the southeast coast could feel some strong northerly gusts to 65 km/hr just after it hits land in Cornwall around 0300h Monday morning. A band of moderate to heavy rain will bring 20-30 mm rainfalls and risk of spot flooding in southern counties. Winds mainly backing to northeast at around 20-40 km/hr during this phase. Further north, patchy light rain in moderate N to NW winds, lows 6-8 C except 10-12 C southeast. There could also be some clear intervals in the far north. A close watch is being kept on the storm and updates will be posted if the impacts for Ireland change significantly.

    MONDAY ... Strong winds will probably abate for a time during the early morning hours to about 0800h except near the southwest coast possibly, but then will redevelop from the west to northwest, backing to southwest as troughs develop across most regions with gusts to perhaps 70-90 km/hr. Except for some rain across the south coast early morning, skies could clear briefly in the morning, then further showers are likely in the windy conditions later.

    Forecasts for Britain

    TODAY ... Very windy across the south this morning (W 80-130 km/hr) with widespread tree damage and some disruptions to travel, bursts of heavy rain continuing (a further 5-10 mm in places), some local flooding mostly from overnight heavy rains in the central regions, and morning highs near 15 C with afternoon readings near 10 C. Storm force winds even stronger across Channel, southern North Sea, and nearby France, Belgium to mid-day or afternoon. Wales can expect some moderate gusts later from the northwest, and mostly cloudy skies with a few showers. Northern England and Scotland continue mostly cloudy with moderate westerly winds and showers, highs near 10 C.

    OUTLOOK ... Somewhat colder late Monday and Tuesday but then back to a mild and unsettled pattern with occasional strong winds.


    Forecasts for North America

    Partly to mostly cloudy and milder in many parts of the east with some outbreaks of drizzle or light rain in Ohio valley. Sunny and very mild to warm across southeast, south central and inland southwest, highs generally into the mid-20s. Showers and mountain flurries in the far west spreading south into parts of Nevada and western Utah, windy at times in Arizona but dry. Snow in parts of Alberta and Montana, dry and cold further east across the northern plains and Canadian prairies (temperatures near -5 C). My local weather on Sunday was mostly sunny (cloud was banked up just to the east of the Cascades) and pleasant with a high near 13 C.

    Tuesday, 29 October, 2013

    Forecasts for Ireland


    TODAY ... Variable cloud, more frequent sunny breaks in the east, and most of the remaining showers near the west coast (2-5 mm on average there). Moderate westerly breezes will continue 30-50 km/hr with highs 11-13 C.

    TONIGHT ... Clear intervals, rather cold, but increasing cloud after midnight. Lows could briefly touch 0-3 C then temperatures will probably rise gradually.

    WEDNESDAY ... Showers or periods of rain, windy, mild. Lows 5-7 C and highs 12-14 C. Rainfalls 5-15 mm.

    THURSDAY ... Some dry weather in north and east to start, cloudy with rain developing in south, lows 5-8 C and highs 12-14 C.

    OUTLOOK ... Rain and wind likely at times from Friday to Sunday, temperatures around 10 C, then breezy to windy and a bit cooler, continued rather unsettled. Guidance is somewhat scattered as to timing, but the stronger winds are likely to arrive Friday night or Saturday, and early estimates are for moderately strong gusts in the 70-100 km/hr range. There is also little change in this unsettled Atlantic-dominated pattern foreseen in the week after next weekend.


    Forecasts for Britain

    TODAY ... Partly cloudy, breezy, showers some with hail and thunder, winds west to northwest 40-70 km/hr then clearing from west later afternoon. Highs 12-14 C.

    TONIGHT ... Clear intervals, cool. Lows 3-6 C.

    OUTLOOK ... Similar to Ireland, mainly mild and unsettled with strong winds likely again by the weekend. No sure indications yet for anything as strong as Monday's gales in the south but it remains a possibility.


    Forecasts for North America

    Cold air across western Canada and the northern tier of the U.S. tonight will continue to sink south, allowing a milder Pacific flow to return to Alberta later today, bringing a sharp rise in temperatures there once the snow melts or sublimates and fog dissipates. Snow will continue to push further south into higher parts of the American Rockies and some parts of the Great Basin. Showers will extend from eastern California to western New Mexico as warmer air is pushed east into Texas and the southern plains states. Very mild in the southeast, and slowly turning milder in the northeast U.S. and Great Lakes regions. My local weather on Monday was sunny and mild with a high near 16.

    Forecasts for Ireland


    TODAY ... Showers or periods of rain, breezy to windy, mild. Lows 5-7 C and highs around 13-15 C. Rainfalls 5-15 mm. Winds SSW 35-55 km/hr veering more westerly, somewhat higher gusts near west coast.

    TONIGHT ... Variable cloud, mild, showers more confined to west and north coasts. Southwest winds continuing in the 30-50 km/hr range. Lows 8-10 C.

    THURSDAY ... Some dry intervals between showers in north and east to start, cloudy with rain developing in south and west, and highs 12-14 C. Rainfalls about 5-10 mm.

    FRIDAY ... Possible heavy rain at times in the south (another low will track past Ireland to the south) and showers further north, winds variable and sometimes light but picking up again later in the day to W 40-60 km/hr. Lows near 7 C and highs near 12 C.

    SATURDAY ... Breezy and possibly windy at times, showers or periods of rain, winds SSW 40-70 km/hr veering to westerly later, lows 5-7 C and highs somewhat cooler 9-11 C.

    SUNDAY ... This could change as models get a better handle on a complex situation, but early indications suggest a rather chilly and wet day with highs only around 6 to 8 C except 8-11 C in Munster. Winds could turn more to the east or northeast in Ulster, Leinster and north Connacht. This might produce fog or mist closer to the weak frontal boundary.

    OUTLOOK ... That slightly cooler turn does not seem to have much staying power and it will likely turn milder again with more of what most weather forum people call "mild muck" -- don't shoot the messenger.


    Forecasts for Britain

    TODAY ... Increasing cloud but mostly dry east, light showers developing further west, highs near 10 C.

    TONIGHT and THURSDAY ... Mild and breezy with rain at times, lows near 8 C and highs 12-14 C.

    FRIDAY ... Heavy rain likely in the south, slight risk of strong wind gusts near Channel as a low follows a similar track to Sunday night's event although at a different time of day and not appearing quite as strong on the charts (also not likely to deepen any more than its moderate strength in England). Highs will reach about 14 C in the south and 11-13 C elsewhere. Some rainfalls of 25-50 mm possible.

    OUTLOOK ... Similar trends to Ireland over the weekend and beyond, as a frontal boundary slowly presses south. Some parts of Scotland could see a touch of snow on hills at least around Sunday, but it's more likely to be a cold drizzly rain lower down in Scotland and much of northern England, while staying closer to 10-12 C in the south.


    Forecasts for North America

    A rather strong storm will develop gradually in Colorado today, leading to an outbreak of thunderstorms later today, tonight and on Thursday in the central plains and Midwest states. Temperatures as warm as 22 C will spread north ahead of this low and reach central Missouri, Illinois and Indiana but further north it will be 13-16 C. That is about as mild as today will get in most of the Great Lakes and northeast states and some northern parts of New England will remain in shallow colder air near 7 C. Continued very warm in the south, as gusty showers spread east into New Mexico and Texas, Oklahoma. Snow has now fallen on higher parts of the Great Basin but valleys are well above freezing. That trend will continue, meanwhile milder air is spreading across the Canadian prairies ahead of weak frontal systems dropping southeast from the Yukon. Pacific moisture is finally reaching the west coast further south after what is probably about to become the driest October on record in my region. Today was another sunny, mild day (15 C after a chilly start).

    Forecasts for Ireland


    TODAY ... Some dry intervals between showers in east to start, cloudy with rain developing in south and west, and highs 12-14 C. Rainfalls about 5-10 mm. Moderate southwest winds 40-60 km/hr.

    TONIGHT ... Cloudy with a few showers or periods of light rain, lows 7-9 C.

    FRIDAY ... Possible heavy rain at times in the south (another low will track past Ireland to the south) and showers further north, winds variable and sometimes light but picking up again later in the day to W 40-60 km/hr and highs near 12 C. Potential for 20-30 mm rainfalls in south.

    SATURDAY ... Breezy and possibly windy at times, showers or periods of rain, winds SSW 40-70 km/hr veering to westerly later, lows 5-7 C and highs somewhat cooler 9-11 C. A further 20-30 mm rain possible, some spot flooding likely to develop inland south.

    SUNDAY ... Rather chilly and wet with highs only around 6 to 8 C except closer to 11 C in Munster. Winds could turn more to the east or northeast in Ulster, Leinster and north Connacht. This might produce fog or mist closer to the weak frontal boundary. Once again the rainfalls are likely to be heavier in the south with 10-15 mm possible there.

    OUTLOOK ... That slightly cooler turn does not seem to have much staying power and it will likely turn milder again with very mild conditions mid-week in a strong southwest flow, then becoming even more windy or possibly stormy towards the end of next week and the weekend of 9-10 November.


    Forecasts for Britain

    TODAY ... Mild and breezy with showers at times, and highs 12-14 C.

    TONIGHT into FRIDAY ... Heavy rain likely in the south, slight risk of strong wind gusts near Channel as a low follows a similar track to Sunday night's event although at a different time of day and not appearing quite as strong on the charts (also not likely to deepen any more than its moderate strength in England). Overnight lows 8-10 C, and highs about 14-15 C in the south and 11-13 C elsewhere. Some rainfalls of 25-50 mm possible.

    OUTLOOK ... Similar trends to Ireland over the weekend and beyond, as a frontal boundary slowly presses south. Some parts of Scotland could see a touch of snow on hills at least around Sunday, but it's more likely to be a cold drizzly rain lower down in Scotland and much of northern England, while staying closer to 10-12 C in the south.


    Forecasts for North America

    The secondary severe weather season has arrived -- heavy storms with some severe weather will extend from around Chicago to New Orleans today and from about Detroit to northwest Florida by tonight. This very active front will continue to bring storms to the east coast on Friday. However, today there will be cloudy and warm with highs near 23 C as far north as NYC and 15 C in New England in strong southerly winds. Turning colder in stages across the northern and central plains states, but not a severe drop in temperatures, just back to more normal values near 10 C. Unsettled across the Rockies with snow in many higher elevations, and rain moving onto the west coast to end a three-week dry spell there. My local weather on Wednesday was cloudy with light rain arriving after 4 p.m., and the high was about 14 C.

    Friday, 1 November, 2013

    Forecasts for Ireland


    TODAY ... After some moderate rather than heavy rain at times in the south this morning (another low will track past Ireland to the south) with patchy light showers further north, skies will become partly cloudy with showers redeveloping mid-day, as winds become variable and sometimes light but then increase again later in the day to W 40-60 km/hr with highs near 12 C. Potential for further 5-10 mm rainfalls in south (about 10-15 mm appears to have fallen overnight).

    TONIGHT ... Becoming windy with showers, winds increasing to SW 40-60 km/hr with some higher gusts by morning near west coast, 5-10 mm rain and lows around 7 or 8 C.

    SATURDAY ... Breezy and possibly windy at times, showers or periods of rain, winds SSW 50-80 km/hr veering to westerly later (strongest gusts near south coast), and highs somewhat cooler 9-11 C. A further 20-30 mm rain possible, some spot flooding likely to develop inland south. Leinster may become quite windy in the afternoon and evening (W-NW 50-80 km/hr) and while Ulster and inland Connacht could have rather light winds much of the day, they will also see a gradual increase towards late afternoon.

    SUNDAY ... Rather chilly and wet with highs only around 6 to 8 C except closer to 11 C in Munster. Winds could turn more to the east or northeast in Ulster, Leinster and north Connacht. This might produce fog or mist closer to the weak frontal boundary. Once again the rainfalls are likely to be heavier in the south with 10-15 mm possible there. Skies becoming variable with the odd break towards late afternoon in central and northern counties.

    MONDAY ... Rather chilly compared to recent days with isolated showers or drizzle in a mostly cloudy northeast backing to northwest breeze, morning lows about 2-5 C and afternoon highs 7-9 C.

    OUTLOOK ... Milder in stages, very windy at times (SW 60-100 km/hr) and highs rapidly returning to low teens, very mild nights likely in the windy Atlantic flow. Several rather strong lows will race past to the north and any one of them could intensify enough to produce a few severe gusts, most likely around Thursday and Sunday but timing is very preliminary at this stage.


    Forecasts for Britain

    TODAY and TONIGHT ... Heavy rain likely in the south, slight risk of strong wind gusts near Channel as a low follows a similar track to Sunday night's event although at a different time of day and not appearing quite as strong on the charts (also not likely to deepen any more than its moderate strength in England). Overnight lows 8-10 C, and highs about 14-15 C in the south and 11-13 C elsewhere. Some rainfalls of 25-50 mm possible. Very mild overnight with lows 8-12 C. Rain tapering to showers or drizzle from west to east. At this point, winds are not expected to increase much in any part of England, but could get rather gusty over the Channel and in northern France.

    OUTLOOK ... Similar trends to Ireland over the weekend and beyond, as a frontal boundary slowly presses south. Some parts of Scotland could see a touch of snow on hills at least around Sunday or Monday, but it's more likely to be a cold drizzly rain lower down in Scotland and much of northern England, while staying closer to 10-12 C in the south. Monday could see some locally heavy rainfalls in southeast England as the weak system predicted for Ireland on Sunday slowly intensifies while drifting further southeast.


    Forecasts for North America

    Eastern regions very mild with showers and thunderstorms, gusty SSW winds veering to WSW later, highs 18-21 C. Great Lakes, Midwest, Ohio valley and mid-south will all be turning a bit cooler in gusty westerly winds, rain or showers. Temperatures here will be falling from morning highs of 15-18 C to about 7-11 C later. Clearing and mild in Texas and western sections of the central plains. Rather bland and milder than average in most of the west with some rain here and there. My local weather on Thursday was overcast and rather foggy with a bit of rain at times but probably not enough to spoil our chances of the driest October in many years (normally, like western Ireland, Oct and Nov are wet months around here).

    UPDATE _ Sat 2 Nov 2013 _ 0545h
    ________________________________

    ALERT issued for strong and possibly damaging wind gusts across southwest this morning, gradually spreading northeast towards Leinster by afternoon. A small but powerful low has developed a strong circulation off the west coast and will soon begin to move inland near Galway Bay. The strongest winds will be closer to Kerry and south Clare, but all regions south of the track are at risk for gusts to 70 knots in well exposed locations from south veering to west later in the event. Some squally showers could have briefly tornadic wind gusts. Rainfalls will generally not be too heavy (5-15 mm). By afternoon the strong wind gusts, somewhat reduced to about 55 knots, will be mainly across central counties and north Leinster, parts of east Ulster. It is likely that the very strong winds will continue on the west coast most of the day and could become more extreme when the low is further inland. Monitor conditions and advisories from appropriate government agencies for any possible storm surge in Galway Bay as this now appears possible by afternoon. Some tree damage and power cuts seem likely, driving will be very hazardous partly due to cross-winds, and high tides could be accompanied by overtopping of sea walls in some harbours facing south or west. Marine areas could see wind gusts to force 11-12 off the southwest coasts, seas will become extremely rough with towering waves, and the public are strongly discouraged from risky observing locations as seas could build very rapidly later today, also climbing is strongly discouraged due to even stronger winds on high terrain (180 km/hr possible at summit level in Kerry), or further north due to dense fog and zero visibilities north of the track and ahead of the warm fronts of this system. Watch for updates. Conditions will deteriorate a little more gradually in Wicklow and Dublin climbing areas but could be very bad this afternoon there.

    Forecasts for Ireland

    TODAY ... Very windy with squally showers, some with thunder, except in Mayo, Sligo, Donegal and north Ulster, low cloud, frequent rain and moderate east winds. For most regions, see alert for details, strong gale to storm force wind gusts developing from south veering to west by afternoon, increasing gradually to 80-110 km/hr with gusts to 140 km/hr. Today's highs will be 11-13 C. The southeast may not see quite as strong a blast of winds as the main track from Kerry/Clare to Dublin/Meath as this system is quite compact, but still would expect some gusts to 55-60 knots in Waterford, Wexford and Wicklow. Topography will distort the extreme winds, people on the roads will notice frequent large variations in wind speed and direction making conditions even more treacherous. As the low appears set to intensify during the day, more extreme conditions could develop, watch for updates. In general, winds will be strongest about 2-4 hours after the low has passed to north of any given location.

    TONIGHT ... Very strong winds gradually dying out (W-NW 60-100 km/hr by midnight) with squally showers mainly in north and west, trending to light rain or drizzle by morning, lows 4-6 C.

    SUNDAY ... Variable cloud, showers turning to periods of rain in south, winds much lighter however, backing to east or northeast in the afternoon and evening. Highs 7-10 C and feeling quite cold especially in Ulster, north Leinster. Rainfalls in south about 10 mm.

    MONDAY ... Rain ending early morning for a time, some clearing, frosty to start in central counties, morning lows -1 to +4 C, then increasing cloud, winds increasing from west, occasional light rain, highs 8-11 C.

    TUESDAY ... Very mild and windy with rain or drizzle at times, winds WSW 60-90 km/hr, lows near 6 C and highs near 12 C.

    WEDNESDAY ... Very mild, drizzle or light rain, winds SW 70-110 km/hr, lows near 11 C and highs near 14 C.

    THURSDAY ... Very mild, windy, rain. Lows near 10 C and highs near 14 C.

    OUTLOOK ... Very windy and mild with further rain, perhaps a little more settled by following week but signals for record warmth around mid-month (15-18 C possible).


    Forecasts for Britain

    TODAY will start partly cloudy with isolated showers, rain moving away from southeast, highs near 12 C in most regions, 14 C south. Strong winds and heavy, squally showers will rapidly overspread Wales, western England and southwest Scotland by afternoon, winds rising to reach SSW 70-120 km/hr (ESE 50-80 km/hr in western Scotland). Rainfalls of about 10 mm by late afternoon.

    TONIGHT will become very stormy in most regions with gale to storm force westerly winds developing, most damaging for north Wales and north-central England, gusts to 140 km/hr there, otherwise 110 km/hr. Northern Scotland will stay in more moderate easterly winds with the low tracking through central Scotland. Lows 7-10 C.

    SUNDAY will be windy to start, then calmer by mid-day except for continuing gales in eastern Scotland, highs 8-10 C.

    SUNDAY NIGHT into MONDAY will see rain, heavy at times, crossing Wales and southern England. Lows 7-10 C and highs 7-10 C as temperatures then begin to drop. Some snow could fall on high summits in Wales.

    OUTLOOK is for the same very windy and mild to warm conditions as in Ireland later in the week.


    Forecasts for North America

    Generally turning much cooler across the east, rain or showers, highs near 15 C. Clear and mild central regions, wet and windy near the west coast. My local weather on Friday was wet and rather mild at 11 C. About 20 mm of rain has fallen since morning here.

    An update will definitely be posted today around 1100-1200h. Note, the new moon occurs on Sunday at 1251 UT (GMT) with an eclipse in equatorial Africa. This factors into the forecast in terms of storm surge potential at high tides on west-facing coasts this afternoon. Check with the relevant sources for that information as it updates.

    Sunday, 3 November, 2013

    Forecasts for Ireland



    New moon occurs today at 12:51, with a total eclipse over equatorial Africa.

    TODAY ... Widespread showers ending for a time but heavy rain likely to spread into Munster and south Leinster by afternoon. A few sunny breaks could develop further north mid-day, and in general it will be rather cool with highs 8-10 C. Rainfalls of 15-30 mm later today and tonight in the south. Morning gusty winds will subside and may back into the northeast in many places by afternoon.

    TONIGHT ... Rain continuing in the south, some isolated and perhaps sleety showers further north but also some clear intervals with ground fog or mist forming, slippery roads could develop due to black ice as lows fall to the range of -1 to 3 C (4-7 C south).

    MONDAY ... Rain ending early morning for a time, some clearing, frosty to start in central counties with patchy black ice hazards on roads, and morning lows -1 to +3 C, then increasing cloud, winds increasing from west, occasional light rain, highs 8-11 C.

    TUESDAY ... Very mild and windy with rain or drizzle at times, winds WSW 60-90 km/hr, lows near 6 C and highs near 12 C.

    WEDNESDAY ... Very mild, drizzle or light rain, winds SW 70-110 km/hr, lows near 11 C and highs near 14 C.

    THURSDAY ... Very mild, windy, rain. Lows near 10 C and highs 12 to 14 C.

    OUTLOOK ... Very windy and mild with further rain into the weekend of 9th and 10th, perhaps a little more settled by following week but a dry spell that starts out rather cool is likely to turn very mild later.


    Forecasts for Britain

    TODAY will be windy to start, then calmer by mid-day except for continuing gales in eastern Scotland, highs 8-10 C. Some light rain or showers dying out with sunny intervals possible by mid-day or afternoon.

    TONIGHT into MONDAY will see rain, heavy at times, crossing Wales and southern England (20-40 mm potential, spot flooding). Lows 7-10 C and highs 7-10 C as temperatures then begin to drop. Some snow could fall on high summits in Wales.

    OUTLOOK is for the same very windy and mild to warm conditions as in Ireland later in the week.


    Forecasts for North America

    Eastern regions dry and mild with some sunshine, central portions of the U.S. windy and mild with rain developing, snow developing late in the day and overnight into Monday for the northern plains and eastern prairies after a mild start, some falls of 10-20 cm likely. Rain and windy on the west coast. My local weather on Saturday was very wet (50 mm rain in frequent downpours) and foggy at times with highs near 11 C. We now move back to standard time in North America.

    Monday, 4 November, 2013

    Forecasts for Ireland


    TODAY ... Frost with some risk of slippery roads due to black ice this morning should quickly clear away with sunshine for a while, then increasing cloud, except in far north where cloud and some showers already present. Most places however will remain dry until late evening when some rain arrives from the west. Winds light until late afternoon then westerly 30-50 km/hr with highs 8-11 C.

    TONIGHT ... Cloudy, light rain and moderate westerly winds 35-55 km/hr with higher gusts near Donegal Bay and Galway Bay. Lows 4-7 C.

    TUESDAY ... Rather mild and windy with rain or drizzle at times, winds WSW 60-90 km/hr, lows near 6 C and highs near 12 C.

    WEDNESDAY ... Continuing rather mild, drizzle or light rain, winds increasing late in the day to SW 70-110 km/hr in north, 40-70 km/hr south, morning lows 5-8 C and highs near 12 C.

    THURSDAY ... Very mild, windy, rain. Lows near 10 C and early highs 12 to 14 but falling off to about 6-8 C by afternoon, partial clearing to follow.

    FRIDAY ... Partly cloudy with a few showers, after a rather chilly start (lows about 2-4 C) then highs 10-12 C.

    SATURDAY ... Somewhat uncertain with guidance quite variable from different models, seems likely to be windy and unsettled and could possibly turn considerably colder late in the day. Highs about 8-10 C before that happens.

    SUNDAY ... The general theme of forecast guidance is cool to start and much milder towards evening, possibly a frost if the more extreme solutions are right, but highs struggling back towards 8-10 C perhaps not until evening or overnight.

    MONDAY to WEDNESDAY of following week are indicated to become much milder and could get well above 10 C in a strong southwest flow.


    Forecasts for Britain

    TODAY ... Rain clearing away from the southeast, rather chilly northeast winds for the south, but milder westerlies spreading into parts of the north, so that highs will be only 6-9 C south, but 10-12 C in parts of Scotland and northern England.

    TONIGHT ... Clear with early frost in some eastern counties, otherwise increasing cloud with rain by morning, temperatures 1-4 C rising to 5-7 C.

    OUTLOOK ... Similar trends to Ireland for most regions of Britain but if the cold turn materializes next weekend, Scotland and higher parts of northern England could see snow, albeit not lasting very long as warmer air quickly pushes in by Monday.


    Forecasts for North America

    Cool and dry in northeast U.S. and Great Lakes region, trending to mild or warm and sunny in the southern U.S. ... somewhat milder air is pushing into the Midwest too, with rain in parts of the upper Midwest and western Great Lakes trending to snow in the Canadian prairies. Another rather weak system is spreading cloud and rain into lower elevations of B.C. and WA while snow is falling above 700m. My local weather on Sunday was partly cloudy and rather chilly with highs near 7 or 8 C.

    Tuesday, 5 November, 2013

    Forecasts for Ireland


    TODAY ... Rather mild and windy with rain or drizzle at times, winds in more exposed locations WSW 50-80 km/hr, although 30-50 km/hr for most, and highs near 12 C. Further rainfalls 1-3 mm on average.

    TONIGHT ... Brief clearing inland north could allow some near frost or even short-lived black ice on some roads (lows 0-4 C) but the southern half of the country will remain under enough cloud and with a westerly breeze to stir the air, lows will generally be 5-8 C there. Just some light rain or drizzle in west Munster and possibly later in Connacht.

    WEDNESDAY ... Continuing rather mild, drizzle or light rain, winds increasing late in the day to SW 70-110 km/hr in north, 40-70 km/hr south, morning lows 5-8 C and highs near 12 C. Strong winds will blow all night in the north and may peak around Thursday 0600-0800h at 80-120 km/hr. It won't be that windy further south, WSW 50-80 km/hr.

    THURSDAY ... Very mild, windy, rain. Lows near 10 C and early highs 12 to 14 but falling off to about 6-8 C in the north by afternoon, with partial clearing to follow by evening.

    FRIDAY ... Partly cloudy with a few showers, after a rather chilly start (lows about 2-4 C) then highs 10-12 C.

    SATURDAY ... Breezy to windy with variable skies, showers sometimes rather blustery with hail or thunder possible, and a cooling trend by afternoon and evening. The coldest part of this brief incursion may come well before midnight so that lows near freezing will be replaced Sunday morning by rising temperatures. (see Britain forecast for my thoughts on how close this gets to being wintry in Ireland, it could perhaps snow on highest summits in Donegal and Mayo on Saturday night).

    SUNDAY ... The general theme of forecast guidance remains cool to start (in Ulster and north Leinster in particular) but much milder towards evening, possibly a brief pre-dawn frost with lows -2 to +3 C but highs struggling back towards 8-10 C perhaps not until evening or overnight, 10-12 C in west as rain redevelops.

    MONDAY to WEDNESDAY of following week are indicated to become much milder and could get well above 10 C in a strong southwest flow. There are some hints of a very warm inversion developing which could fail to break down in some northern areas mid-week or later, but it doesn't look like the milder conditions will be prevented from mixing down in the south, west or probably central counties although dense fog and some rather cold overnight lows might be part of this picture by mid-week. However, earlier in the week when guidance is more reliable, it should be very mild night and day with some rain in southwest winds of 50-80 km/hr.


    Forecasts for Britain

    TODAY ... Frequent showers for most regions with somewhat drier conditions spreading in from the west by afternoon, highs 10-12 C, winds W 50-80 km/hr in exposed locations.

    TONIGHT ... Clearing at times with cooler conditions except in the south, lows generally -3 to +2 C but 4-7 C south. Black ice likely to be fairly widespread on roads in parts of rural, inland northern England, Wales and southern Scotland.

    OUTLOOK ... Similar trends to Ireland for most regions of Britain but if the cold turn materializes next weekend, Scotland and higher parts of northern England could see snow, albeit not lasting very long as warmer air quickly pushes in by Monday. The coldest part of this brief incursion is currently timed for late overnight which favours some rather low minima on Sunday morning, to about -4 C in parts of the inland central and northern counties of England and Wales, southern Scotland. Snow, if any does fall, would be most likely in north Wales, Cumbria and over higher parts of central Scotland.


    Forecasts for North America

    Conditions are changing rather slowly in all regions, so continued dry and near normal temperatures in parts of the eastern U.S. and Canada, rain spreading slowly east into the Great Lakes from the Midwest, highs 10-13 C, and mild to warm further south with showers along the weak trailing fronts of the Great Lakes disturbance. Snow tapering to flurries in the northern plains and eastern prairies, clearing further west for a time, light rain moving onto the west coast. My local weather on Monday was generally fair but cool with highs near 7 or 8 C. Drizzle has begun to fall since sunset.

    Wednesday, 6 November, 2013

    Forecasts for Ireland


    TODAY ... Continuing rather mild, drizzle or light rain, winds increasing in stages to reach 40-70 km/hr by late afternoon, and highs around 10 to 12 C. Rainfalls generally light, 3-5 mm.

    TONIGHT ... Strong winds will develop later tonight in the north and may peak around 0700-1100h at 80-120 km/hr. It won't be that windy further south, WSW 50-80 km/hr. Some drizzle or light rain and a brief burst of heavier showers in the north as winds begin to ramp up, temperatures could be a bit lower inland south but most places staying around 7-9 C or even rising somewhat to 10-11 C north.

    THURSDAY ... Very mild, very windy at first (70-110 km/hr), with periods of rain, then more moderate but steady SW winds 50-70 km/hr. Early highs 12 to 14 but falling off to about 6-8 C in the north by afternoon, with partial clearing to follow by evening. Highs about 11-13 C further south at the more ordinary early afternoon hours.

    FRIDAY ... Partly cloudy with a few showers, after a rather chilly start (lows about 2-4 C) then highs 10-12 C.

    SATURDAY ... Breezy to windy with variable skies, showers sometimes rather blustery with hail or thunder possible, and a cooling trend by afternoon and evening. The coldest part of this brief incursion may come well before midnight so that lows near freezing will be replaced Sunday morning by rising temperatures. (see Britain forecast for my thoughts on how close this gets to being wintry in Ireland, it could perhaps snow on highest summits in Donegal and Mayo on Saturday night, but this would melt on Sunday).

    SUNDAY ... The general theme of forecast guidance remains cool to start (in Ulster and north Leinster in particular) but much milder towards evening, possibly a brief pre-dawn frost with lows -2 to +3 C but highs struggling back towards 8-10 C perhaps not until evening or overnight, 11-13 C in west as rain redevelops. Sunday night looks very mild with strong southwest winds, light rain and temperatures steady 10-12 C.

    MONDAY to WEDNESDAY of following week are indicated to stay mild and could get well above 10 C in a strong southwest to west flow. Around mid-week it will probably get a little cooler under high pressure but this will quickly change back to a mild southwest pattern later in the week but with the speed of systems developing in a racing jet stream, trying to time events this far in advance is difficult. We have reached that part of the year when the solar angle is so low that air mass temperature begins to dominate over the daily cycle, and temperatures can be up at night and down in the daytime if the fronts are timed that way. The average temperature will probably be 1-2 deg above normal. Rainfall in general should not be too heavy and the strong winds will assist in drying.

    TODAY ... Partly cloudy with isolated showers, moderate westerly winds of about 40-70 km/hr, highs 9-11 C.

    OUTLOOK ... Similar trends to Ireland for most regions of Britain but if the cold turn materializes next weekend, Scotland and higher parts of northern England could see snow, albeit not lasting very long as warmer air quickly pushes in by Monday. The coldest part of this brief incursion is currently timed for late overnight which favours some rather low minima on Sunday morning, to about -4 C in parts of the inland central and northern counties of England and Wales, southern Scotland. Snow, if any does fall, would be most likely in north Wales, Cumbria and over higher parts of central Scotland. It will turn much milder on Sunday night and stay very mild for most of next week.


    Forecasts for North America

    The rather weak disturbance in the central plains and Midwest is gaining strength slowly and will start to drop heavier amounts of rain today with about 15-25 mm likely in Chicago and St Louis. The dry, not overly mild conditions under mostly cloudy skies will persist nearer to the east coast. Somewhat colder air is pressing south into west-central Canada behind the snowfall that is now largely done, but new snowfalls are beginning in higher portions of the western mountains with rain at lower elevations in rather chilly temperatures not reaching 10 C. The southwest remains warm and dry however. My local weather on Tuesday was overcast with some light rain, fog and drizzle at times, highs near 9 C.

    Thursday, 7 November

    Forecasts for Ireland



    ALERT for isolated gusts to 120 km/hr possible at times this morning in well-exposed locations in northwest counties, from a southwest direction. It is expected that most other locations will peak at around 90-100 km/hr.

    TODAY ... Becoming very windy this morning especially across northern counties (SW 70-110 km/hr), with blustery showers (hail and thunder possible especially around 10-11 a.m.) or periods of rain, then brief clearing followed by more showers in more moderate but steady SW winds 50-70 km/hr. Highs 12 to 14 may be reached rather early in the northwest where temperatures will fall off to about 6-8 C by afternoon. Highs about 11-13 C further south will occur during the more usual early afternoon hours. Rainfalls will vary from 3-7 mm south to 7-12 mm north.

    TONIGHT ... Showers generally ending although they could persist in some parts of west Munster and Connacht. Clear intervals will develop and it will become much less windy. Lows of 2-5 C are expected with slight risk of localized ground frost.

    FRIDAY ... Partly cloudy with a few showers, after a rather chilly start (lows about 2-4 C) then highs 10-12 C. Moderate WSW breezes and rainfalls of about 2-5 mm on average.

    SATURDAY ... Breezy to windy with variable skies, showers sometimes rather blustery with hail or thunder possible, and a cooling trend by afternoon and evening. Morning lows -2 to +3 C, afternoon highs 6-9 C north, 8-11 C south.

    SUNDAY ... Clear intervals around midnight could lead to early frost (in Ulster and north Leinster in particular) after which temperatures are likely to rise steadily towards 5-8 C by morning, then periods of rain, heavier in west, very mild by afternoon and evening, highs near 13 C. Potential for 20-30 mm rainfalls ending late overnight.

    OUTLOOK for next week is generally mild and breezy with frequent frontal passages and wind shifts from SW to WNW. The first of these is timed for Monday night or early Tuesday, a second one is likely around Wednesday afternoon or evening, and a third and perhaps stronger front could arrive towards the following weekend, after which temperatures may fall considerably for a few days. But until then, highs will generally be around or a little above 10 C, nights could be cold at times but depending on timing of cloud and frontal passages, for example Sunday night and again Wednesday night temperatures would likely stay quite high with strong winds. The south could see a pleasant dry spell for two or three days when high pressure drifts closer around Wednesday to Friday. Confidence on the colder turn (after Sunday 17th) is only moderate as the Atlantic influence may continue to at least some extent.


    Forecasts for Britain

    TODAY ... Partly cloudy with showers, strong south-westerly winds of about 50-80 km/hr will increase to about 70-110 km/hr in the north by afternoon and evening with highs 9-13 C. Not as windy over some parts of inland southern England, where trend will also be dry for a time then a steady rain is expected later when a front moving south of Ireland reaches Britain and stalls overnight.

    OUTLOOK ... Similar trends to Ireland for most regions of Britain but if the cold turn materializes next weekend, Scotland and higher parts of northern England could see snow, albeit not lasting very long as warmer air quickly pushes in by Monday. The coldest part of this brief incursion is currently timed for late overnight which favours some rather low minima on Sunday morning, to about -4 C in parts of the inland central and northern counties of England and Wales, southern Scotland. Snow, if any does fall, would be most likely in north Wales, Cumbria and over higher parts of central Scotland. It will turn much milder on Sunday night and stay very mild for most of next week.


    Forecasts for North America

    Rain spreading faster to the east now, should reach the east coast later today with temperatures falling across the Midwest and Great Lakes, inland northeast. Highs near 15 C on the east coast trending to 5-7 C further west. The west coast is also seeing heavier rainfalls from a slow-moving frontal system coming ashore. Most central regions are generally dry if cloudy, with a minor disturbance bringing patchy sleet or light rain to parts of the central plains states. My local weather on Wednesday was overcast with mainly dry conditions, rain this evening however, and highs 7-9 C.

    Friday, 8 November, 2013

    Forecasts for Ireland



    TODAY ... Partly cloudy with frequent showers in western counties, some of these spreading to east after a dry start, highs 10-12 C. Moderate WSW breezes 30-50 km/hr and rainfalls of about 2-5 mm on average although could reach 10 mm in parts of inland west, midlands.

    TONIGHT ... Showers ending in most areas, partial clearing and quite cold with frost and some icy stretches on roads, most problematic in central and inland northern counties. Lows -3 to +2 C.

    SATURDAY ... Breezy to windy with variable skies, showers sometimes rather blustery with hail or thunder possible, afternoon highs 6-9 C north, 8-11 C south. Rainfalls generally 3-5 mm.

    SUNDAY ... Clear intervals from Saturday evening to a little after midnight could lead to early frost (in Ulster and north Leinster in particular) after which temperatures are likely to rise steadily towards 5-8 C by morning, then periods of rain, heavier in west, very mild by afternoon and evening, highs near 13 C. Potential for 20-30 mm rainfalls ending late overnight. Strong southwest winds developing, 70-100 km/hr in exposed parts of west and north, not too windy south or east until later in the day.

    MONDAY ... Windy, very mild, showers at times but also some hazy sunshine in parts of south and east, morning lows 8-11 C and afternoon highs 12-14 C. Winds WSW 70-110 km/hr may diminish somewhat by afternoon.

    TUESDAY ... Breezy with variable cloud, isolated showers, not quite as mild with morning lows 3-6 C and highs 9-12 C.

    WEDNESDAY ... Very mild again, windy with rain sweeping through north and showers at times further south, highs 11-14 C.

    OUTLOOK ... This roller coaster ride of alternating very mild and seasonable days looks set to continue on roughly a two-day cycle although a longer-term cooling trend is still being diagnosed by the models, albeit not as strong a cooling as some had shown previously.


    Forecasts for Britain

    TODAY ... Rain, heavy at times, spreading into the south (15-30 mm) and highs 8-11 C. Further north, variable cloud, showers, highs near 10 C.

    WEEKEND OUTLOOK ... Similar to Ireland although cold air will dominate Saturday night and the milder air mass won't arrive until mid-day in Britain, however, latest guidance suggests more of a sleety mix on hills in the north with snow on higher summits only.

    FURTHER OUTLOOK ... The variable and windy pattern will be fast-moving so that even the timing for Britain will be similar to Ireland, albeit a few hours slower for eastern counties of England.


    Forecasts for North America

    Weak systems now dominate in a cool zonal flow, the wet frontal system that had dominated eastern regions for days has quickly swept through eastern Canada overnight and is being followed by cool, cloudy weather with some light flurries in places, trending to sunshine and near normal temperatures closer to the Great Lakes and inland northeast U.S. ... rain or sleet in parts of the Midwest with highs 5-8 C. ... showers turning to snow inland in western regions. My local weather on Thursday was cloudy with some rain at times, highs near 7 C.

    Saturday, 9 November, 2013

    Forecasts for Ireland



    TODAY ... Breezy to windy at times with partly cloudy skies, showers sometimes rather blustery with hail or thunder possible, afternoon highs 6-9 C north, 8-11 C south. Rainfalls generally 3-5 mm. Winds W 30-50 km/hr turning more northwesterly afternoon and evening. Some snow could settle on higher summits in the north by evening and may be visible for a while Sunday morning before it either melts or disappears behind cloud (and melts).

    TONIGHT ... Clear intervals and frosty in parts of north and east, more cloud likely with milder temperatures south and west. Lows -3 to +2 C north and east but rising from near +2 to +7 in south and west towards morning, with rain and strengthening southwest winds for west Munster.

    SUNDAY ... Periods of rain, heavier in west, very mild by afternoon and evening, highs near 13 C. Potential for 20-30 mm rainfalls ending late overnight. Strong southwest winds developing, 70-100 km/hr in exposed parts of west and north, not too windy south or east until later in the day. The windy and showery conditions will last most of Sunday night and come to an end around Monday morning.

    MONDAY ... Windy, very mild to start but turning a bit cooler by afternoon, showers at times but also some hazy sunshine in parts of south and east, morning lows 8-11 C and morning highs 12-14 C falling off to 8-10 C. Winds WSW 70-110 km/hr may diminish somewhat by afternoon.

    TUESDAY ... Breezy with variable cloud, isolated showers, not quite as mild with morning lows 3-6 C and highs 9-12 C.

    WEDNESDAY ... Very mild again, windy with rain sweeping through north and showers at times further south, highs 11-14 C.

    OUTLOOK ... This roller coaster ride of alternating very mild and seasonable days looks set to continue on roughly a two-day cycle although a longer-term cooling trend is still being diagnosed by the models, albeit not as strong a cooling as some had shown previously. The idea of an inversion high with fog in many areas becoming rather persistent around end of the week is back in the mix and will have to be watched, some places could break free from this fog and have some nice mild afternoon sunshine, other places might be stuck with low cloud and mist all day and that could keep things rather cold. In the longer term, a more variable and at times colder pattern could develop, although I don't see anything resembling 2010 in the works.


    Forecasts for Britain

    TODAY ... Sunny intervals, isolated wintry showers in north, rain or hail south, highs 6-8 C.

    TONIGHT ... Widespread frost, some wintry showers on higher terrain in north, lows -4 to +2 C.

    OUTLOOK ... Similar to Ireland by later Sunday as the roller coaster arrives, and temperatures head up towards a peak near 14 C mid-day Monday, down slightly for Tuesday then back up again Wednesday.


    Forecasts for North America

    Somewhat milder in parts of the lower Great Lakes, northeast U.S. and Midwest, with mixed rain and wet snow further north. Cloudy further south with outbreaks of light rain from a weak system heading for the inland southeast tonight. Mild and dry in the central plains and southwest, snow in parts of western Canada ahead of quite a cold push of arctic air from Yukon and NWT towards the prairies. This won't affect the west coast where it will stay partly cloudy and showery, but some mountain ranges will see a bit of light snow. My local weather on Friday was cloudy but mainly dry and cool with highs about 7 C.

    Sunday, 10 November, 2013

    Forecasts for Ireland


    Now comes that crazy part of the year when nights can be warmer than days, for example, Sunday night when temperatures are likely to peak near or after midnight in the mid-teens.


    TODAY ... Periods of rain spreading gradually northeast, heavier in west, very mild by afternoon and evening, highs near 13 C (temperatures could be slow to rise above 7 C in north Leinster and east Ulster until evening). Potential for 20-30 mm rainfalls ending late overnight. Strong southwest winds developing, 70-100 km/hr in exposed parts of west and north, not too windy south or east until later in the day.

    TONIGHT ... The windy and showery conditions will last most of the night tapering to drizzle, with temperatures up as high as 14-16 C in the south, and 12-14 C further north, foggy on northern hills. Winds should moderate slowly from west to east, but may start as gales from the southwest (70-110 km/hr in exposed locations).

    MONDAY ... Windy, very mild to start but turning a bit cooler by afternoon, showers at times but also some hazy sunshine in parts of south and east, morning lows 8-11 C and morning highs 12-14 C falling off to 8-10 C. Winds from the WSW will diminish somewhat later morning then pick up somewhat again by afternoon, reaching 40-70 km/hr.

    TUESDAY ... Breezy with variable cloud, isolated showers, not quite as mild with morning lows 3-6 C and highs 9-12 C. There should be good sunny intervals for much of the south and east.

    WEDNESDAY ... Becoming very mild again after a rather cold start to the day, and eventually windy (WSW 60-100 km/hr) with rain sweeping through north and showers at times further south, lows -1 to +4 C, then highs 11-14 C.

    THURSDAY ... Continuing rather mild despite winds shifting more northwesterly, showers ending, morning lows 4-7 C and afternoon highs about 10 to 12 C.

    FRIDAY ... Foggy in most locations for a significant part of the morning, and in a few places all day long, but hazy sunshine likely to burn through the mist to make for quite a mild afternoon. Morning lows 2-5 C and afternoon highs at least 7-10 C in fog or mist, 10-14 C in any sunshine.

    FURTHER OUTLOOK ... Mild and breezy, turning a little cooler each day Sunday to Tuesday then much colder mid-week. Highs about 10 C on the weekend, 5-8 C early in the following week, but could drop near or below freezing briefly mid-week (models seem fairly consistent on timing but intensity looks a bit overdone on some). This colder spell could bring some brief lying snow in northern counties, but it doesn't appear to be anything likely to last very long.


    Forecasts for Britain

    TODAY ... Sunny intervals, cold, some wintry showers in north, highs 6-9 C.

    TONIGHT ... Rain, fog, strong southwest winds developing, temperatures rising to about 13-15 C in south, 10-13 C north.

    FURTHER OUTLOOK ... Similar to the forecast for Ireland even for timing, as systems will be moving very quickly.


    Forecasts for North America

    Mild in the eastern U.S., turning much colder in stages across the Great Lakes and Midwest, eventually snow showers are likely (by Tuesday). Cold across inland western Canada and northern plains states, temperatures falling well below -10 C by day and to near -25 C at night. This very cold air will not get very far south as a strong zonal flow develops and weak lows zip east from near Vancouver B.C. to Chicago and on into New England. Anything south of that will stay mild or if close to the boundary will have frequent variations around 3-5 C. Staying quite warm across the southern U.S. ... My local weather on Saturday was overcast with mostly dry conditons and highs of about 10 C.

    Monday, 11 November, 2013

    Forecasts for Ireland


    TODAY ... Breezy, very mild to start but turning a bit cooler by afternoon, showers at times but also some hazy sunshine developing, morning to mid-day highs 12-14 C falling off to 8-10 C. Winds from the WSW will diminish somewhat later morning then pick up somewhat again by afternoon, reaching 40-70 km/hr. Further rainfalls 1-3 mm.

    TONIGHT ... Cloudy intervals, isolated showers or drizzle and colder with lows around 2-5 C.

    TUESDAY ... Breezy with variable cloud, isolated showers, not quite as mild as today with highs 9-11 C. There should be good sunny intervals for much of the south and east.

    WEDNESDAY ... Becoming very mild again after a rather cold start to the day, and eventually windy (WSW 60-100 km/hr) with rain sweeping through north and showers at times further south, lows -1 to +4 C, then highs 11-14 C. Rainfalls of 10-20 mm north but only trace to 5 mm south.

    THURSDAY ... Continuing rather mild despite winds shifting more northwesterly, showers ending, morning lows 4-7 C and afternoon highs about 10 to 12 C.

    FRIDAY ... Foggy in most locations for a significant part of the morning, and in a few places all day long, but hazy sunshine likely to burn through the mist to make for quite a mild afternoon. Morning lows 2-5 C and afternoon highs at least 7-10 C in fog or mist, 10-14 C in any sunshine. Some persistent light rain in moderate southwest winds for northern counties by afternoon and evening, lighter winds prevailing across the south.

    FURTHER OUTLOOK ... Mild and breezy, turning a little cooler each day Sunday to Tuesday then much colder mid-week. Highs about 10 C on the weekend, 5-8 C early in the following week, but could drop near or below freezing briefly mid-week (models still seem fairly consistent on timing and intensity now begins to line up with potential for one or two days with highs in the rather cold 3-5 C range) -- this colder spell could bring some brief lying snow in northern counties, but it doesn't appear to be anything likely to last very long although it may stay cooler than average with frequent frosts when the deeper cold comes to an end after a two or three day visit -- and confidence on this is only moderate at this range.


    Forecasts for Britain

    TODAY ... Rain, fog, strong southwest winds developing, temperatures rising to about 13-15 C in south, 10-13 C north.

    FURTHER OUTLOOK ... Similar to the forecast for Ireland even for timing, as systems will be moving very quickly.


    Forecasts for North America

    Mild in the eastern U.S., turning much colder in stages across the Great Lakes and Midwest, eventually snow showers are likely (by Tuesday). Cold across inland western Canada and northern plains states, temperatures falling well below -10 C by day and to near -25 C at night, but later today Alberta will be warmed by chinook winds to near +7 C. The very cold air will not get very far south as a strong zonal flow develops and weak lows zip east from near Vancouver B.C. to Chicago and on into New England. Today, one of these fast-moving systems will bring 3-5 cm snowfalls to parts of Montana, Wyoming and South Dakota. Anything south of that will stay mild or if close to the boundary will have frequent variations from around 3-5 C to near -10 C. Staying quite warm across the southern U.S. ... My local weather on Sunday was overcast and rather mild with mostly dry conditons and highs of about 12 C. The sun was dimly visible at times through dense altostratus cloud.

    Tuesday, 12 November, 2013

    Forecasts for Ireland


    TODAY ... Breezy (WNW 30-50 km/hr) with variable cloud, isolated showers developing in the north, not quite as mild as today with highs 9-11 C. There should be good sunny intervals for much of the country.

    TONIGHT ... Clear to start in south and east, becoming frosty by about midnight there, lows -3 to +2 C. Cloudy intervals south and west, becoming overcast, lows 3-7 C.

    WEDNESDAY ... Becoming very mild again after a rather cold start to the day, and eventually windy especially in Connacht and west Ulster (WSW 60-100 km/hr) with rain sweeping through north and showers at times further south, then highs 11-14 C. Rainfalls of 10-20 mm north but only trace to 5 mm south.

    THURSDAY ... Continuing rather mild despite winds shifting more northwesterly, showers ending, morning lows 4-7 C and afternoon highs about 10 to 12 C.

    FRIDAY ... Foggy in most locations for a significant part of the morning, and in a few places for much of the day, but hazy sunshine likely to burn through the mist to make for quite a mild afternoon. Morning lows 2-5 C and afternoon highs at least 7-10 C in fog or mist, 10-14 C in any sunshine. Some persistent light rain in moderate southwest winds for northern counties by afternoon and evening, lighter winds prevailing across the south.

    FURTHER OUTLOOK ... Mild and breezy, turning a little cooler each day Sunday to Tuesday then much colder mid-week. Highs about 12 C on Saturday and 10 C on Sunday, then only 5-8 C early in the following week, in strong northwest winds and wintry showers (snow looks possible in higher parts of the north) and it could drop near or below freezing briefly mid-week (models still seem fairly consistent on timing and intensity now begins to line up with potential for one or two days with highs in the rather cold 3-5 C range) -- this colder spell could bring some brief lying snow in northern counties, but it doesn't appear to be anything likely to last very long although it may stay cooler than average with frequent frosts when the deeper cold comes to an end after a two or three day visit -- but confidence on all of this is only moderate at this range. Another possible solution is more of a frosty high replacing the mild zonal flow without as much wind or wintry showers. Note that all of this is a week or more into the future. My research model is showing support for a colder week around then. Unlike 2010, I don't see this deepening into severe wintry conditions.


    Forecasts for Britain

    TODAY ... Showers ending and becoming partly cloudy, continued very mild with highs 13-15 C. Somewhat colder by afternoon in Wales and Scotland.

    FURTHER OUTLOOK ... Similar to the forecast for Ireland even for timing, as systems will be moving very quickly. Thursday could be considerably colder in Scotland than in Ireland or the rest of Britain as that turn to northwesterly winds will be tapping a shallow pool of arctic air near Iceland.


    Forecasts for North America

    Turning rather cold (8-12 C) in the southeast U.S. in a modified arctic outbreak there, but unseasonably cold for much of the northeastern U.S., Midwest, Great Lakes regions, bands of snow squalls although not a very heavy outbreak due to unfavourable upper level wind alignment. Highs only -3 to +3 C and considerably colder in northern Great Lakes and northern plains states, eastern prairies. Much milder further west thanks to a developing chinook, partly cloudy over most of the inland west with rain hugging the outer coasts in a backing south to southeast flow bringing much milder air north from California towards Washington state and British Columbia. My local weather on Monday was pleasantly mild with some brief sunny intervals and highs reached 14 C.

    Just a note on Haiyan, that intense typhoon lost strength over the weekend while making a steady approach to the Vietnam-China border, and is now just a frontal wave moving east through south-central China. I'll keep an eye on the remnants just to see if it can be identified or if it gets absorbed into other systems as it approaches my part of the world. The remnants of several other tropical systems are out ahead of it between Japan and North America. A new storm forming east of Mindanao early today local time seems unlikely to develop much beyond tropical storm strength but will interfere with the relief efforts with its rain bands.

    Wednesday, 13 November, 2013

    Forecasts for Ireland


    TODAY ... Sunny intervals for east and south, cloudy west and north, becoming very mild again, and eventually windy especially in Connacht and west Ulster (SW veering to W 70-110 km/hr) with rain sweeping through north and showers at times further south, highs 11-14 C. Rainfalls of 10-20 mm north but only trace to 5 mm south. Strong and damaging gusts possible around Donegal Bay in well exposed locations.

    TONIGHT ... Continuing windy, temperatures slowly falling from evening levels near 12 C to eventual lows of 4-7 C. Rain becoming more intermittent and showery then ending in all but far northern locations, partial clearing.

    THURSDAY ... Continuing rather mild despite winds shifting more northwesterly, still rather windy in the north (40-70 km/hr), markedly less windy in south, any further showers ending, with afternoon highs about 10 to 12 C.

    FRIDAY ... Foggy in most locations for a significant part of the morning, and in a few places for much of the day, but hazy sunshine likely to burn through the mist to make for quite a mild afternoon. Morning lows 2-5 C and afternoon highs at least 7-10 C in fog or mist, 10-14 C in any sunshine. Some persistent light rain in moderate southwest winds for northern counties by afternoon and evening, lighter winds prevailing across the south.

    SATURDAY ... Mild with some sunshine in southeast, otherwise overcast with light rain developing later in the day, morning lows 3-7 C and highs about 11 or 12 C.

    SUNDAY ... Variable cloud, isolated showers, turning a bit cooler in fresher west to northwest breezes, rain by evening. Lows 2-5 C and highs 7-10 C.

    FURTHER OUTLOOK ... All guidance indicates quite a cold week to follow this mild spell, but details are far from "nailed down" and there could be several attempts to bring in cold enough air masses for snow with either near-miss or partial results depending on region, chances for snow appearing to be greatest mid-week in the north. On average, highs will be around 5-7 C and overnight lows in the moderate frost range of -4 to -2 C but locally it could be a bit colder than that especially if any snow cover develops. The end of this potential cold spell could be rather gradual in terms of less windy and more settled but cool weather to follow, before possibly a return to milder conditions around the end of November. At this point, the chances for snow next week appear best in parts of Ulster and inland Connacht, and on higher ground further south. Mixed showers and hail will also feature prominently as will moderate to strong northwest winds at times.


    Forecasts for Britain

    TODAY ... After a sunny start in most regions, cloud will increase with rain sweeping into Scotland, northwest England and Wales before evening. Other regions are likely to remain dry, with rising temperatures peaking late evening near 13-14 C, and winds rising to SW gales of 60-100 km/hr in most regions but severe local gusts in western Scotland to 130 km/hr.

    TONIGHT ... Very windy and mild with rain tapering off to showers, temperatures steady 11-13 C then falling in western and northern regions to around 5-7 C.

    OUTLOOK ... Much cooler in Scotland and northern England on Thursday, somewhat cooler than today in other regions, all in strong northwest winds with frequent showers north, some snow on hills. Much less windy for most on Friday and Saturday, mild except where any fog fails to dissipate mid-day. Highs generally 8-10 C but could reach 12-14 C locally on Saturday. From then on, roughly the same outcome as for Ireland, a steady drop into below normal temperatures for the better part of a week.


    Forecasts for North America

    Much milder today in the Midwest, Great Lakes and Ohio valley as southwest winds arrive with highs 11-14 C. Further east it will stay cold until tonight when temperatures will begin to rise from today's near freezing highs. This warm front is largely dry but some light snow is possible over Quebec and northern New England at times. Most of western Canada will enjoy a few mild days now ahead of a weekend push of colder air and some snow Friday night, so until then, mild and dry with highs 8-11 C. My local weather on Tuesday was hazy and mild with a few morning showers, highs near 14 C.

    Thursday, 14 November, 2013

    Forecasts for Ireland


    Expect a rather significant change in the weather pattern next week, with temperatures peaking around 12-14 C on Saturday, then a steady decline to values much closer to freezing in the daytime, with severe frosts for a few days next week, and the risk of small amounts of snow in some northern counties (and on higher ground elsewhere). If you're travelling to eastern North America, an even larger change will take place but over the space of a few hours on Monday 18th. Details in the relevant section below.


    TODAY ... Mostly cloudy with some sunny breaks developing by afternoon, still rather windy this morning (NW 40-70 km/hr except 60-100 km/hr in north Ulster), becoming much less windy in the south by afternoon, with any further showers ending, with afternoon highs about 10 to 12 C.

    TONIGHT ... Clear intervals developing, fog may be dense in some inland south and central locations, lows generally 2-5 C but could fall lower in one or two frost-prone locations, and will stay 5-8 C in coastal Connacht and Ulster.

    FRIDAY ... Foggy in most locations during part of the morning, and in a few places this fog could be dense with near-zero visibilities, variable high cloud above this fog but hazy sunshine likely to burn through the mist to make for quite a mild afternoon. Morning lows 2-5 C and afternoon highs at least 7-10 C in fog or mist, 10-14 C in any sunshine. Some persistent mist or drizzle in moderate southwest winds for northern counties by afternoon and evening, lighter winds prevailing across the south. As long as fog does not persist, good drying conditions likely.

    SATURDAY ... Mild with some sunshine in southeast, otherwise overcast with light rain developing later in the day, morning lows 3-7 C and highs about 11 or 12 C. Rain becoming a bit heavier overnight then tapering off to showers.

    SUNDAY ... Variable cloud, isolated showers, turning a bit cooler in fresher west to northwest breezes, rain by evening. Lows 2-5 C and highs 7-10 C.

    FURTHER OUTLOOK ... Monday and Tuesday will become colder with moderate northwest winds, showers becoming wintry on higher ground in north, but also some sunny intervals, lows -3 to +2 C and highs 4-7 C ... Wednesday could be even colder with significant snowfalls developing in parts of the inland north and on higher ground elsewhere, highs only 2-5 C after morning lows near -3 to -1 C ... following this, turning somewhat milder in stages as the northerly feed is cut off by a weak although cool zonal westerly flow in the north, and anticyclonic conditions in the south. Severe or sharp frosts may continue but daytimes may not be as cold and certainly more settled or less windy. The evolution is not too reliable past seven days and the strong North American storm may blast through all of the postulated weak features to create a more rapid warming trend (which would be around Thursday or Friday of next week).


    Forecasts for Britain

    TODAY ... Windy and feeling rather cold despite highs 8-11 C, frequent showers some with hail and thunder, but a few sunny intervals too, with the exception of central Scotland which could see frequent mixed or wintry showers over higher ground and highs only 4-7 C.

    TONIGHT ... Clearing with winds dropping off to moderate in north and light in south, fog developing in some areas. Lows -4 to +2 C inland, 3-5 C coastal.

    OUTLOOK ... Much less windy and partly cloudy or sunny after fog lifts for most on Friday and Saturday, mild except where any fog fails to dissipate mid-day. Highs generally 8-10 C but could reach 12-14 C locally on Saturday. From then on, roughly the same outcome as for Ireland, a steady drop into below normal temperatures for the better part of a week. Mixed precip or cold rain more likely than snow in southern England.


    Forecasts for North America

    Today will feature widespread milder fall weather with partly cloudy skies, just a few light showers in parts of the inland northeast (possibly starting as sleet before warm fronts pass), highs reaching 10 C in northeast states but 15-20 further west. Really cold air is currently bottled up in the far north or else being flushed out of New England. This pattern won't change very much on Friday but the colder air will then begin to press south, bringing widespread snowfalls to inland western Canada by about Friday night or Saturday. A very strong fall storm will develop over the plains states with heavy snowfalls to its north, and severe thunderstorms near the cold fronts. This will push into the Great Lakes region by Monday and temperatures are likely to drop from 15-18 in the warm sector to -7 or lower in the cold arctic gales to follow. Heavy snow squalls will develop on Monday in west to northwest winds of 80-100 km/hr. This sudden change will reach the east coast Monday night. Temperatures in New York City for example could drop from 21 C to -5 C from mid-day Monday to Tuesday morning. Severe thunderstorms are likely from the Ohio valley to the New England coast and further south into Alabama to the Carolinas during this event. ... Almost an afterthought, my local weather on Wednesday was cloudy and very mild at 15 C. This is the developing stage of the storm to come. Meanwhile, remnants of Haiyan are today phasing with a separate system to the west of Japan. Not much will happen now to these remnants and the energy of the monster typhoon is mostly dissipated.

    Forecasts for Ireland


    TODAY ... Foggy in some parts of the inland south and west during part of the morning, otherwise generally overcast although thin layers of high cloud in some parts will allow some sunshine to break through, highs 11-14 C. Some persistent mist or drizzle in moderate southwest winds for northern counties by afternoon and evening, lighter winds prevailing across the south.

    TONIGHT ... The higher cloud will persist with some breaks, watch for a lunar halo around the almost full moon, with mist or fog patches likely by dawn, and lows 4-7 C.

    SATURDAY ... Mild with some sunshine through partial high cloud in southeast, otherwise overcast with light rain developing later in the day, and highs about 11 or 12 C. Rain becoming a bit heavier overnight then tapering off to showers.

    SUNDAY ... Variable cloud, isolated showers, turning a bit cooler in fresher west to northwest breezes, rain becoming heavy by evening. Lows 2-5 C and highs 7-10 C. Potential for 10-20 mm rainfalls during the afternoon and evening to overnight period.

    FURTHER OUTLOOK ... Monday and Tuesday will become colder with moderate northwest winds, showers becoming wintry on higher ground in north, but also some sunny intervals, lows -3 to +2 C and highs 4-7 C ... Wednesday could be even colder with significant snowfalls developing in parts of the inland north and on higher ground elsewhere, highs only 2-5 C after morning lows near -3 to -1 C ... following this, turning somewhat milder in stages as the northerly feed is cut off by a weak although cool zonal westerly flow in the north, and anticyclonic conditions in the south. Severe or sharp frosts may continue but daytimes may not be as cold and certainly more settled or less windy. The evolution is not too reliable past seven days and the strong North American storm may blast through all of the postulated weak features to create a more rapid warming trend (which would be around Thursday or Friday of next week). These views from yesterday have not really changed with the latest guidance and it remains quite uncertain how cold it may actually get mid-week and also how long that degree of cold might then last. The average of all guidance would suggest some potential for snow by about Wednesday, and a very gradual warming trend thereafter.


    Forecasts for Britain

    TODAY ... Some weak sunshine at times through layers of higher cloud, mist or fog in a few valleys may persist, but for most places good visibility and dry with highs 10-13 C.

    OUTLOOK ... Much less windy and partly cloudy or sunny after fog lifts for most on Friday and Saturday, mild except where any fog fails to dissipate mid-day. Highs generally 8-10 C but could reach 12-14 C locally on Saturday. From then on, roughly the same outcome as for Ireland, a steady drop into below normal temperatures for the better part of a week. Mixed precip or cold rain more likely than snow in southern England but solutions are quite varied on different models, the most likely theme is cold, wet and a little above freezing except for snow on hills and more widely in Scotland.


    Forecasts for North America

    Becoming windy and turning much colder in western Canada, snow developing tonight and becoming heavy over some parts of the Rockies by tomorrow, mixed or sleety precip on the coast as far south as Portland OR by late Saturday, but remaining somewhat warmer in the southwest states. Very mild all weekend in central and eastern regions with rain developing, turning stormy on Sunday in central regions, very strong winds across the Midwest and Great Lakes reaching the northeast states by Monday. Highs this weekend will reach the mid to high teens to low 20s in the southeast, but the air mass replacing this on Monday will become sub-freezing by the overnight hours and heavy snow squalls with winds gusting to 100 km/hr are likely in the Great Lakes region Monday. Severe thunderstorms are likely in many areas of the eastern U.S. by Sunday, reaching the east coast on Monday, then rapid clearing on gale force westerly winds. ... My local weather on Thursday was generally clear and mild with highs near 14 C. Rain is expected by morning.

    Saturday, 16 November, 2013

    Forecasts for Ireland


    TODAY ... Mild with some weak sunshine through partial high cloud in southeast, otherwise overcast with light rain developing later in the day, and highs about 11 or 12 C. Rain becoming a bit heavier overnight then tapering off to showers.

    TONIGHT ... Cloudy with some clear intervals, isolated showers mainly over northwest, lows 2-5 C.

    SUNDAY ... Variable cloud, isolated showers, turning a bit cooler in fresher west to northwest breezes, rain becoming heavy by evening, with highs about 8-12 C. Potential for 10-20 mm rainfalls during the afternoon and evening to overnight period.

    MONDAY ... Becoming quite windy (WNW 50-80 km/hr) with passing showers containing some hail and dropping snow on high terrain. Lows about 2-4 C and highs 8-10 C.

    TUESDAY ... Cloudy with sunny intervals, cold, passing showers becoming wintry over higher parts of north. Lows -2 to +2 C and highs 6-9 C.

    WEDNESDAY ... Partly cloudy, sleety showers at times, cold. Lows -2 to +2 C and highs near 8 C.

    OUTLOOK ... Milder air will try to work its way back in from the west, and may eventually succeed at least in western counties, but the temperature trend will be rather slow to rise overall as nights may become colder in more anticyclonic conditions. Confidence is not overly high beyond mid-week and a possible solution would be much faster warming with a return to above normal temperatures.


    Forecasts for Britain

    TODAY ... Some weak sunshine at times through layers of higher cloud, mild with a few showers developing in north by afternoon. Highs 12-14 C south and 10-12 C north.

    TONIGHT ... Rain developing, mild, foggy. Lows 5-8 C.

    OUTLOOK ... Similar trends to Ireland from Sunday onward, with a gusty frontal passage Monday leading in much colder weather. When the milder air begins to push weakly back into Ireland, it may take several days longer to reach most of Britain, so that there will be continuing threats of light snow in parts of eastern England and higher parts of the north, and somewhat lower daytime highs in the 2-5 C range later in the week.

    Forecasts for North America

    Becoming windy and much colder in western Canada, 10-20 cm snow developing from early morning and becoming heavy over some parts of the Rockies by this afternoon, mixed or sleety precip on the coast as far south as Portland OR by late Saturday, but remaining somewhat warmer in the southwest states with scattered showers and a few thunderstorms in gusty southwest winds. Very mild all weekend in central and eastern regions with rain developing, turning stormy on Sunday in central regions, very strong winds across the Midwest and Great Lakes reaching the northeast states by Monday. Highs this weekend will reach the mid to high teens to low 20s in the southeast, but the air mass replacing this on Monday will become sub-freezing by the overnight hours and heavy snow squalls with winds gusting to 100 km/hr are likely in the Great Lakes region Monday. Severe thunderstorms are likely in many areas of the eastern U.S. by Sunday, reaching the east coast on Monday, then rapid clearing on gale force westerly winds. .. meanwhile, my weather on Friday was wet and colder than recent days with highs of about 7C.

    Sunday, 17 November, 2013

    Forecasts for Ireland


    Astronomy note: Full moon occurs today at 15:17h.

    TODAY ... Cloudy, still rather mild in the south and east, where it should remain dry until well into the afternoon. Rain will spread from Connacht and Donegal into Munster and rest of Ulster around mid-day, 5-10 mm likely. Highs 8-10 C north and 9-12 C south.

    TONIGHT ... Rain ending as showers in north and west, becoming windy after midnight (NW 50-70 km/hr), lows 2-5 C. Rain continuing most of the night elsewhere, lows 4-7 C.

    MONDAY ... Windy and colder with passing squally showers with some hail, snow on higher terrain. Winds NW 50-80 km/hr, highs 6-9 C.

    TUESDAY ... A frosty start, some sunshine followed by increasing cloud, winds backing into the west but remaining rather strong at 40-70 km/hr. Rain will then arrive during the late afternoon or evening. Morning lows -2 to +3 C and highs 7-10 C.

    WEDNESDAY ... Morning showers with gusty northwest to northerly winds, lows about 2-5 C and highs 5-8 C, feeling very cold due to the winds.

    THURSDAY ... Cold with isolated wintry showers, some accumulations of snow possible during the early morning in higher parts of north. Lows -1 to +3 C and highs 6-9 C.

    FRIDAY to SUNDAY currently looking somewhat milder although nights could remain frosty, but days should feel milder, due more to slack winds than warming temperatures with lows generally -3 to +1 C and highs 7-10 C.


    Forecasts for Britain

    TODAY ... Increasing cloud, showers developing north and west, highs 9-12 C.

    OUTLOOK ... The pattern will be similar to Ireland with rain and gusty winds moving through early Monday and again Tuesday night or Wednesday, but some snow could fall in north and on higher ground. Highs will be generally about 8 to 10 C. Later in the week western districts will probably see some improvement but eastern regions could remain in more of a wintry north to northeast flow and highs only 4-7 C there.


    Forecasts for North America

    Stormy conditions will develop across the Midwest, Ohio valley and central plains states with severe thunderstorms and a sudden fall in temperatures from near 18 C to around 7 C, winds gusting from SW to about 100 km/hr. Rain and thunderstorms will develop further east and this sharp front will arrive there tonight. Cold and windy in parts of central Canada and the northern plains states. A new disturbance is moving inland from the Pacific and will bring rain to low elevations, snow to mountains across much of the western interior, although it will be dry in the southwest U.S. with seasonably mild highs there (15-20 C). My local weather on Saturday was cloudy with a few sunny breaks, isolated showers, and the snow line has come down to about 400m now with highs near sea level of 7 C.

    Monday, 18 November, 2013

    Forecasts for Ireland


    TODAY ... For northern and most western counties, breezy and colder with passing squally showers with some hail, snow on higher terrain. Winds NW 40-60 km/hr, highs 6-9 C. For south and east, as well as lower terrain in southwest, mixture of sunshine and cloud, isolated showers, occsaionally breezy (W-NW 30-50 km/hr) and highs 8-10 C.

    TONIGHT ... Clear intervals with lows -2 to +3 C, frost in sheltered spots but ongoing northwesterly winds 40-60 km/hr will prevent widespread frost. A few wintry showers may stream inland around Donegal Bay at times but most places will remain dry.

    TUESDAY ... A cold and frosty start, some sunshine followed by increasing cloud, winds backing into the west but remaining rather strong at 40-70 km/hr. Rain will then arrive during the late afternoon or evening. Morning lows -2 to +3 C and highs 7-10 C.

    WEDNESDAY ... Morning showers with gusty northwest to northerly winds, increasing to 50-80 km/hr, lows about 2-5 C and highs 5-8 C, feeling very cold due to the winds. Rainfalls generally 3-5 mm, some snow on hills by evening.

    THURSDAY ... Cold with isolated wintry showers, some accumulations of snow possible during the early morning in higher parts of north. Lows -1 to +3 C and highs 6-9 C.

    FRIDAY to SUNDAY currently looking somewhat milder although nights could remain frosty, but days should feel milder, due more to slack winds than warming temperatures with lows generally -3 to +1 C and highs 7-10 C.

    OUTLOOK ... Guidance is somewhat mixed but the general trend seems to be a continuation of rather cold and settled conditions although at times it may be close to normal values for late November as slightly milder air seeps into the circulation. There is probably some chance that most guidance will be wrong and we'll see a more rapid return to unsettled and mild conditions -- this is because there hasn't been much consistency to past few days of model output which illustrates that the models probably don't find very strong signals at present. This early in the winter, without a robust cold influence, it's fairly easy for the atmosphere to return to its natural default of a mild westerly.


    Forecasts for Britain

    TODAY ... Showers ending from west to east, some sunny intervals developing, becoming rather breezy with highs 8-11 C.

    OUTLOOK ... The pattern will be similar to Ireland with a cold night ahead, some frost, then widespread rain and gusty winds moving through again on Tuesday night and Wednesday, although some snow could fall in north and on higher ground especially in Scotland. Highs will be generally about 7 to 10 C from north to south. Later in the week western districts will probably see some improvement but eastern regions could remain in more of a wintry north to northeast flow and highs only 4-7 C there.


    Forecasts for North America

    Today will see very strong winds from a westerly direction across most of the Great Lakes and northeast U.S., with snow squalls developing north of the lower Great Lakes where it will remain a bit too mild except on higher hills in PA and NY states. Highs will range from 7 C near the lower lakes to -2 C in the central Great Lakes, and after morning highs near 15 along the eastern seaboard it will drop gradually to about 8 C. Some gusts to 100 km/hr are likely but there won't be any further tornadic storms as the weakening front moves into Quebec and New England, but some wind damage is likely. Further south the weather will remain clear to partly cloudy and rather mild. Colder air wrapping around the deep low will be held back by the rapid development of a new low over Montana which will move quickly northeast, setting off a near-blizzard snowstorm in parts of western Canada inland from the showery Pacific coast, as temperatures across the prairies remain below -10 C except near the border. Into the west-central U.S., much milder air is streaming in from the Pacific today and will hold on for most of the week holding the very cold arctic air in its current location north of the border, although some will seep into Minnesota and the northern parts of Wisconsin and Michigan where heavy lake effect snow will occur. ... My local weather on Sunday was partly to mostly cloudy with a high of 9 C.

    Tuesday, 19 November, 2013

    Forecasts for Ireland


    TODAY ... A cold and frosty start, some slippery roads with a few covered by slushy snow or hail in higher parts of northwest, passing sleety showers but most places will break to intervals of sunshine mid-day followed by increasing cloud, winds backing into the west but remaining rather strong at 40-70 km/hr. Rain will then arrive during the late afternoon or evening and could start as sleet on higher ground. Highs 6-10 C with the higher readings confined to west coast.

    TONIGHT ... Very windy and raw with rain mixing at times with wet snow on higher ground, temperatures steady around 3-4 C at best (except for a few outer coastal locations at 6-7 C). Winds NW 50-80 km/hr will make it feel very close to freezing. Rainfalls 5-8 mm.

    WEDNESDAY ... Rain ending as showers with gusty northwest to northerly winds, 50-80 km/hr, and highs 5-8 C, feeling very cold due to the winds. Further rainfalls generally 1-3 mm, some fresh snow on hills by evening.

    THURSDAY ... Cold with isolated wintry showers, some accumulations of snow in 3-5 cm range possible during the early morning in higher parts of north. Lows -1 to +3 C and highs 6-9 C.

    FRIDAY to SUNDAY still looking somewhat milder although nights could remain frosty, but days should feel milder, due more to slack winds than warming temperatures with lows generally -3 to +1 C and highs 7-10 C.

    OUTLOOK ... A little milder next week, dry in most places for the first few days, and highs 8-11 C, slight to moderate frosts inland.


    Forecasts for Britain

    TODAY ... Cold and windy, a few passing showers (sleety on higher terrain) and also a few sunny intervals, highs 5-8 C. Heavy hail showers may develop in sea effect bands over southwest England and north Wales.

    TONIGHT and WEDNESDAY ... Windy with rain, sometimes mixing with sleet or snow in north and on higher ground in south. Highs 6-9 C. Winds NW to N 60-100 km/hr in more exposed locations.

    OUTLOOK ... Similar to Ireland with a very gradual warming trend, and much less windy after Thursday.


    Forecasts for North America

    Dry and milder in most eastern regions as the strong winds slowly moderate, lake effect snow becoming more confined to central and northern Ontario where it will remain quite cold in gusty NW winds. Very mild in most central regions as southerly winds develop ahead of a front dropping south from Montana. Heavy snow at times to the north of low pressure moving through southern Alberta into Saskatchewan (20-30 cm), highs near -10 C there. Snow also heavy across most of interior B.C. but rain on the coast ending as showers. My local weather on Monday was overcast with rain, heavy at times, and highs near 8 C.

    Wednesday, 20 November, 2013

    Forecasts for Ireland


    TODAY ... Rain ending as showers (by about 0900h near south coast, sooner elsewhere) with gusty northwest to northerly winds, 50-80 km/hr, temperatures steady 6-9 C, but feeling very cold due to the winds. Further rainfalls generally 1-3 mm, some fresh snow on hills by evening.

    TONIGHT ... Not quite as windy and a slow clearing trend although further showers, some becoming wintry on hills, will affect east Ulster and coastal Leinster. Winds northerly 40-60 km/hr. Lows -1 to +3 C, some frost and icy roads in a few inland locations where the wind is not as strong.

    THURSDAY ... Cold with isolated wintry showers, some accumulations of snow in 3-5 cm range possible during the early morning in higher parts of north as well as above 400m in Dublin and Wicklow, highs 6-9 C. Winds north to northeast 30-50 km/hr will make it feel colder.

    FRIDAY to SUNDAY still looking somewhat milder although nights could remain frosty, but days should feel milder, due more to slack winds than warming temperatures with lows generally -3 to +1 C and highs 7-10 C.

    OUTLOOK ... A little milder next week, dry in most places for the first few days, and highs 8-11 C, slight to moderate frosts inland. Fog could become more frequent during this spell, and some of the fog could be persistent given the low solar angle, so highs would not reach those levels where fog fails to dissipate (a few inland valleys). However, for this time of year, the weather will become increasingly pleasant for coastal regions in particular (and that is of course where most people tend to live).


    Forecasts for Britain

    TODAY ... Windy with rain, sometimes mixing with sleet or snow in north and on higher ground in south. Highs 6-9 C. Winds NW to N 60-100 km/hr in more exposed locations. Snow more likely by afternoon and evening on higher ground as freezing levels drop gradually towards 400m.

    TONIGHT and THURSDAY ... Further sleety showers, strong northerly winds, cold and raw with overnight lows -2 to +3 C and highs on Thursday about 5-8.

    OUTLOOK ... Similar to Ireland with a very gradual warming trend, and much less windy after Thursday.


    Forecasts for North America

    Very cold in most of western Canada after a briefly milder spell in southern Manitoba early morning, snow now moving away from the prairies and towards Hudson Bay, highs across most of the populated areas in this region near -15 C and even colder further north. Clear and cool in B.C. under modified arctic air. This colder air is surging south into the central U.S. but will be held up by developing low pressure in Colorado that will move gradually east towards the lower Great Lakes. This is a weak system and will create just light sleety precipitation in parts of the Midwest and central plains. Further south it will be relatively warm at 15-18 C, with a few outbreaks of rain in mostly cloudy conditions. The northeast U.S. and Great Lakes continue to enjoy dry and relatively mild conditions, but far eastern Canada will see strong northerly winds from a developing gale off the Newfoundland coast. Meanwhile my local weather on Tuesday was sunny and cold with a high near 5 C.
