Forecasts for Ireland

TODAY ... Some morning light rain or drizzle should dissipate soon, to be followed by cloudy skies with sunny intervals developing, then increasing afternoon cloud, and further periods of light rain later or by evening (overnight southeast). Highs about 18 to 21 C. Rainfalls in total about 5 mm on average.

TONIGHT ... Showers ending from northwest to southeast mostly before midnight, then some clear intervals, fog patches, lows 7-10 C.

THURSDAY ... Hazy, rather warm, further showers possible with highs 18-21 C. Further rainfalls of 3-5 mm.

FRIDAY ... Partly cloudy, breezy to windy and not quite as warm, isolated showers, winds WSW 40-60 km/hr, lows 8-11 C and highs 16-18 C.

WEEKEND OUTLOOK ... Breezy to windy both days and rather warm again as highs edge back towards 20 C in a moderate W-SW flow. Monday then looks quite blustery and a bit cooler. Showers may be mainly confined to north until about Sunday afternoon-evening then more widespread.


Forecasts for Britain

TODAY will see a few showers developing across central regions reaching parts of the south by afternoon, highs 17-21 C.

The outlook is broadly similar to Ireland beyond that.


Forecasts for North America

Still in Ottawa (in both senses of the term) where we never got into the warmer air that has flooded across the south of Ontario and all of the northeast U.S. Heavy thunderstorms are rumbling past to my north at 0115h local time and more appear to be heading my way for the day, with the heat to the south setting a few records (which are near 35-37 C). I think it might reach 25 C here at some point between clusters of storms. Have my camera ready in case I'm out and about at the right moment. Meanwhile, my quick look at conditions elsewhere reveals little overall change with heat dominating most of the U.S. I must beg your indulgence as I settle into a much briefer on-line "day" that is also at a rather odd hour of "night" but will at least have some active weather for a change -- as you must have noted over four years, I live in one of the least active weather zones on this continent and anywhere else for that matter. Ottawa is a different story with frontal passages that induce envy, even if nothing else does.

Friday, 13 September, 2013

Forecasts for Ireland

TODAY ... Partly cloudy in most regions, some lingering rain south coast, and other showers moving into west but tending to die out later as it becomes more breezy and somewhat cooler with further isolated showers, winds increasing later to WSW 40-60 km/hr, lows 8-11 C and highs 16-18 C.

TONIGHT ... Clear intervals, isolated showers, lows 4-7 C.

SATURDAY ... Partly cloudy to overcast with showers developing, winds increasing later in day to SW 40-60 km/hr. Highs near 19 C.

SUNDAY ... Breezy to windy with highs closer to 17-18 C as winds will rapidly increase from a westerly direction (50-70 km/hr) with rain spreading into the north, showers further south.

MONDAY ... Blustery with squally showers at times, some sunshine too, highs near 16 C.

(sorry limited time today, will resume full forecasts tomorrow ... my local weather in eastern Canada showery and turning much cooler at present).

UPDATE _ Sunday, 15 September, 2013 _ 0630h
____________________________________________

Just an update for today and tomorrow, due to internet time constraints for me ...

TODAY will see rain ending across the east fairly soon, then variable cloud to follow with passing showers. Longer or heavier showers are likely in Connacht and west Ulster. Rainfalls of 5-15 mm are likely. Winds will be southwest 40-70 km/hr at first, then W 50-80 km/hr later, with some higher gusts near squally showers and especially across the northwest coastal regions. Highs of about 17 C will probably occur before mid-day in the south and east, 15 C west and north, and in all cases temperatures are likely to drop a few degrees during the afternoon.

TONIGHT and MONDAY will remain blustery and showery with WNW winds 40-70 km/hr for most regions but 60-100 km/hr near Donegal Bay and exposed areas. Lows near 7 C and highs only 12-15 C.

Had a pleasant sunny day in Ottawa, high 17 C after quite a cool start.

Tuesday, 17 September, 2013

Forecasts for Ireland


TODAY ... Intervals of rain, low cloud or fog in parts of north and east, highs 12-17 C warmest in south and west Munster. Further rainfalls 10-25 mm, heaviest to north of the track of a wave of low pressure likely to track about Sligo to Dublin. Some hazy sunshine could develop by afternoon in parts of the west as this feature and its weak cold front pass to the east.

TONIGHT ... Moderate westerly breezes dying out away from west coast, partly cloudy with clear intervals, rather cold away from south and west coasts, lows 3-6 C but 6-9 C south and west coasts.

WEDNESDAY ... Becoming partly cloudy to sunny at times, showers more isolated if any, and highs 14-17 C. Moderate breezes at times.

THURSDAY to SUNDAY ... Gradual improvements likely with any rain largely confined to north, highs rising through 16-20 C range.

OUTLOOK ... Rather pleasant late summer or warm autumn conditions appear likely to settle in for some time once the current deep low fills up and moves east. The only role of Humberto seems to be assisting in returning the jet stream to the north. Highs could reach the low or even mid 20s as much warmer air settles in over the region next week.


Forecasts for Britain

Rain will spread into the west this morning, heaviest in Wales and the Midlands by mid-day and afternoon, and spreading to the southeast by late in the day. Rather chilly in northern England and Scotland, highs 9-13 C there. Otherwise about 15 C in the rain and 17-19 C by afternoon in the southwest.

The forecast then becomes very similar to the Ireland forecast and much warmer weather will spread in next week.


Forecasts for North America

Today will bring ideal early autumn weather to the Great Lakes, northeast U.S. with highs near 20 C. Cloud and showers are spreading from the plains states into the Midwest but this is a weak and slow-moving system. Further cloud and showers cover the west coast and the southeastern states. Meanwhile there's a late summer warm to hot spell continuing over much of west-central Canada and the northern Rockies, northern plains states.

In Ottawa today, it was clearing up with a fresh, cool northerly breeze and the high was only 13 C. Clear and quite cold out at 0130h.

Thursday, 19 September, 2013

Forecasts for Ireland

Astronomy note: full moon is today at 12:14 IST (at that time, visible mainly from the Pacific regions).

TODAY ... Rain could be heavy at times in Ulster and nearby parts of Connacht and north Leinster, 10-15 mm further this morning ending by mid-day then somewhat clearer skies already present in parts of west and south should gradually replace the rain, leading to some breezy and partly cloudy conditions with a few additional showers and highs 12-15 C north and 15-18 C south.

TONIGHT ... Partly cloudy, isolated showers, lows 5-8 C.

FRIDAY ... Variable cloud, rather mild with highs 16-19 C.

SATURDAY ... Low cloud and some drizzle or light rain at times in north, hazy sunshine developing south, quite humid. Highs 15-20 C.

SUNDAY and into NEXT WEEK ... The current word on the warm spell appears to be that it may peak near 23 C early next week, cool off slightly under continuing sunny skies to 15-17 C range (quite chilly nights with dense fog patches) then another warmer interval would likely follow near end of month.


Forecasts for Britain

TODAY will be wet with rain likely to be heaviest in north Wales and north-central England where 20-40 mm could fall, highs near 16 C. A few thunderstorms could develop across the south, highs near 18 C.

From tonight on, the pattern is basically similar to Ireland.


Forecasts for North America

Warm and dry in the east, highs 22-25 C. Widespread showers and a few thunderstorms central plains and Midwest, highs 24-27 C. Much cooler in western prairies and northern plains, rain may change to sleet or wet snow in places, highs 4-8 C. Heavy rain eastern prairies, upper Midwest and western Great Lakes, highs 10-15 C. Mild to warm and dry in far west, rain spreading onto central B.C. coast. In Ottawa on Wednesday it was clear, warm (almost hot) in the sunshine and around 22 C.

Saturday, 21 September, 2013

Forecasts for Ireland

TODAY ... Low cloud and some drizzle or light rain at times in north and parts of west, hazy sunshine developing south and east, quite humid. Highs 16-22 C with the warmest likely to be inland southeast.

TONIGHT ... Extensive fog or mist, mild. Lows 11-14 C.

SUNDAY ... Hazy sunshine, some coastal low cloud or mist more persistent in west, highs near 22 C inland and 17 C near some coasts.

MONDAY ... Warm sunshine likely inland and east coast, fog or low cloud near most other coasts, morning lows 8-12 C and afternoon highs 17-23 C.

TUESDAY to THURSDAY ... Continued rather warm but probably more extensive low cloud each day across west and north, sunshine becoming more restricted to mid-day hours and only in parts of south and east. Highs falling somewhat into 17-20 C range, somewhat colder at night especially east-central and south inland where 3-7 C possible although cooler locations will then experience dense fog.

OUTLOOK ... It seems likely that relatively warm weather (17-21 C) will persist through the week and into the weekend but it could then turn much cooler (9-13 C) with gusty winds and showers developing.


Forecasts for Britain

In general, the same outlook is valid for Britain, although some spots could reach 25 C early next week, notably south central, west Midlands, inland south Wales. Dense fog will be widespread most nights for the next week and this could persist well into the daytime hours in some valley locations. Very light winds will lead to some persistence of fog or low cloud even into mid-day hours in a few locations.


Forecasts for North America

Heavy showers and thunderstorms will continue to move slowly east to reach a line from about Montreal to Washington DC by afternoon. To the east it will remain sunny and very warm, but the front is weakening and temperatures will fall only a few degrees after it passes (to 17-21 C). Another warm spell will quickly build up next week. Warm dry conditions prevail now almost to the west coast where a front is edging inland with moderate to heavy rainfalls approaching Vancouver and Seattle now. In Ottawa on Friday, the weather was sunny and quite warm (27 C) and at 0130h it is warm and sultry with a strong southwest breeze (21 C). Reports of heavy rainfalls further west with some local flooding around London, Ontario. The front is weakening and I expect to see about 10 mm rain here on Saturday.

Monday, 23 September, 2013

Forecasts for Ireland

TODAY ... Warm sunshine likely inland and east coast, fog or low cloud near most other coasts, morning lows 8-12 C and afternoon highs 17-25 C. The very warm inland readings could edge closer to the west coast as winds back more to southeasterly.

TONIGHT ... Mist or fog patches redeveloping, mild and humid, lows 11-15 C.

TUESDAY to THURSDAY ... Continued rather warm but probably more extensive low cloud each day across west and north, sunshine becoming more restricted to mid-day hours and only in parts of south and east. A few showers may develop most likely in parts of the southwest, and across the north. Highs falling somewhat into 17-20 C range, somewhat colder at night (inland southeast to northeast mainly) with some readings as low as 3-7 C possible although cooler locations will then experience dense fog.

OUTLOOK ... It seems likely that relatively warm weather (17-21 C) will persist through about Friday or Saturday, with increasing chances for rain spreading in from the southwest, after which Sunday and early next week may turn considerably cooler with the risk of strong winds at times, and highs falling into the more seasonable 12-15 C range.


Forecasts for Britain

In general, the same outlook is valid for Britain, although some spots could reach 25+ C each day this week, notably south central, west Midlands, inland south Wales. Dense fog will be widespread most nights for the next week and this could persist well into the daytime hours in some valley locations. Very light winds will lead to some persistence of fog or low cloud even into mid-day hours in a few locations. When rain does develop later in the week, it could take several additional days to spread into all parts of southeast England but will move more readily across Wales, northern England and Scotland.


Forecasts for North America

Most of the eastern half is now under high pressure with gradually warming temperatures although it will be chilly from about Toronto to central PA eastward into the Maritimes where wind and rain continue from a slow-moving low. The western provinces of Canada and adjacent northwest U.S. are under troughs of low pressure and outbreaks of showery rainfall but it remains warm and dry further south. In Ottawa on Sunday, it was partly to mostly cloudy with brief showers and a cool high of 14 C.

I will be back to home base around Monday 30th, meanwhile there may be a few days of travel later this week and I may require a bit of assistance so get ready to repeat these words: "little change expected" works like a charm most of the autumn anyway.

Wednesday, 25 September, 2013

Forecasts for Ireland

TODAY ... Some dense fog inland east and central counties this morning, then becoming partly to mostly cloudy with some brighter intervals, mild to warm again, humid, isolated showers, highs 17-20 C.

TONIGHT ... Cloudy, fog patches, mild, lows 7-10 C.

THURSDAY ... Continued cloudy with a few sunny spells and continued rather warm, highs of about 16-19 C. Some light showers may develop in west.

FRIDAY to SUNDAY ... Cloudy with highs generally 16-19 C and some outbreaks of light rain developing gradually from southwest to northeast.

OUTLOOK ... Models are increasingly "warm" biased now with outbreaks of heavier rain likely to follow towards end of the month into early October in a continued southerly flow. Highs will likely remain around 16-19 C.


Forecasts for Britain

Most regions will have similar conditions to the above forecasts for Ireland, although rainfall will tend to spread more rapidly north than east when it does begin to arrive towards the weekend. Highs could also be slightly warmer in regions to south and east of about B'ham to south Yorkshire, and could reach about 22-23 C on occasion.


Forecasts for North America

Warm and dry in most of the eastern and central U.S. and adjacent parts of eastern Canada, with rain spreading towards the Carolinas and parts of southern Virginia. Outbreaks of rain continue in parts of western Canada and this turns to wet snow over some of the higher terrain. It was a warmer sunny day in Ottawa on Tuesday, high near 18 C and clear overnight with a view of the waning half moon close to Jupiter.

I begin the long trek home on Thursday with various stops en route, so will update the forecast tomorrow, possibly taking a few days off to around Monday after that.

Tuesday, 1 October, 2013

Forecasts for Ireland

TODAY ... Very mild and humid with bands of heavier showers moving north, with some thunder possible ... rainfalls of 10-20 mm on average although some places outside that range ... also a few brief sunny intervals ... winds generally SE 30-50 km/hr but some exposed areas could see much higher gusts at times (Malin Head has reported near 100-km/hr gusts this morning). Highs about 17-20 C. Some heavier rainfalls could develop north-central and inland eastern counties by late afternoon with local potential for 30 mm and flash flooding.

TONIGHT ... Further showers, heavy at times, very mild, moderate southeast winds. Lows 13-16 C. Some further rainfalls of 10-20 mm. Foggy on hills especially in parts of north.

WEDNESDAY ... Heavy showers or periods of rain, very mild, 20-30 mm rainfalls in some places, risk of spot flooding and thundery downpours. Highs about 16-19 C.

THURSDAY ... Continued mild, unsettled, 10 mm rain or more, lows 12-15 C and highs 16-19 C.

FRIDAY ... Showers more isolated, very mild, some sunny breaks developing, misty or foggy in some coastal regions, lows 10-13 C and highs 15-18 C.

SATURDAY ... Cloudy with light rain in parts of north, but hazy sunshine may develop in central and southern regions, very mild or warm, lows 8-11 C and highs 17-20 C.

SUNDAY 6th to TUESDAY 8th ... Very mild or warm, some sunshine, rain more likely in west and north although eventually another rain event for most of the country, highs 18-22 C.

FURTHER OUTLOOK ... In general, somewhat cooler for a few days especially across the north but staying close to normal or a bit above, then warming back into high teens by mid-October.


Forecasts for Britain

In general, the same pattern will prevail, but at first, the rain predicted for Ireland will affect mainly western parts of Britain and much of Scotland. Later this week, heavier rainfalls will spread across eastern regions as well. Temperatures will be similar and warmer than average by 2-4 C deg.

Forecasts for North America

The pattern remains warm and dry in most of the eastern and central regions and cool but wet in the west. Some heavier showers are moving inland overnight and will reach the western prairies and northern plains after brief clearing once the current showers move further east towards northern Ontario. Highs today will range from 20-23 C in the Great Lakes and Midwest to around 26 C in the mid-Atlantic states, all about 5 deg above normal for early October. This warmth also covers large parts of the central states. Temperatures in western Canada are closer to 12-14 C at lower elevations and there has been some early snowfalls on higher terrain. My local weather (now back in Vancouver) was cloudy, windy and showery with highs only 13 C.

Thursday, 3 October, 2013

Forecasts for Ireland

TODAY ... Continued mild, heavy rain (10-20 mm) at times in eastern counties with some thunder, 10-20 mm rain, and highs 16-19 C. Some hazy sunshine at times in west, scattered outbreaks of light rain developing later, 2-5 mm for most locations. Highs 17-20 C.

TONIGHT ... Some heavier rain is likely overnight into early Friday across Leinster. Fog may develop at that time in central counties. Misty or low cloud further west, some clearing inland towards morning. Lows 8-11 C west and about 12 C east.

FRIDAY ... Showers more isolated, very mild, some sunny breaks developing, misty or foggy in some coastal regions, and highs 15-18 C.

SATURDAY ... Cloudy with light rain in parts of north, but hazy sunshine may develop in central and southern regions, very mild or warm, lows 8-11 C and highs 17-20 C.

SUNDAY 6th to THURSDAY 10th ... Very mild or warm, some sunshine, rain more likely in west and north although eventually another rain event for most of the country, highs 18-23 C. Chance of some record high temperatures and very mild at night, lows 11-15 C. Risk of dense fog overnight and morning hours especially inland south and east.

FURTHER OUTLOOK ... Any return to more normal temperatures will perhaps be rather brief as the pattern remains very mild for October. There is some chance of a record warm monthly average (around 13-14 C) after a first half that will almost certainly exceed 15 C.


Forecasts for Britain

TODAY will be very mild to warm but some heavy thundery showers will develop later in the southwest. Highs 18-22 C.

Otherwise, the general outlook is very similar to Ireland with very warm temperatures almost every day for the foreseeable future, rain mostly in the western and northern regions.


Forecasts for North America

Continued very warm and sunny in the east, outbreaks of thundery rain in the Midwest, as systems are rather slow-moving. There is also some dry and warm weather in parts of the central and southwestern states. Rain is moving across the Rockies and other western mountains with some brief clearing on the west coast. My local weather on Wednesday was wet and chilly with highs only 11-12 C.

Saturday, 5 October, 2013

Forecasts for Ireland

TODAY ... Mostly cloudy with some brighter intervals across the south and east, a few outbreaks of drizzle or light rain at times in the north. Highs 17-20 in the south and east, 15-18 C north.

TONIGHT ... Cloudy, mild, drizzle in parts of north, fog or mist. Lows 9-13 C.

SUNDAY ... Cloudy with some intervals of hazy sunshine in the south and east, isolated showers but most places dry except for extensive morning dew, mild or warm with highs 18-21 C.

MONDAY ... Continuing warm with some risk of locally heavy showers across the far north, isolated showers elsewhere but also some hazy sunshine at times, lows 10-13 C and highs 18-21 C.

TUESDAY to THURSDAY ... Hazy sunshine and quite warm, light winds, mist or extensive fog may be slow to clear in morning hours inland, lows 8-11 C and highs 18-22 C.

FURTHER OUTLOOK ... The pattern seems likely to continue with only minor variations to produce one of the warmer Octobers in recent years.


Forecasts for Britain

The pattern will be similar to the above with temperatures generally running about five degrees above normal in most regions. On Monday, the heavier showers that might graze parts of Ulster will definitely head for western and central Scotland where 10-20 mm rain could develop. Otherwise most of England and Wales will be in a warm, dry pattern with risk of dense fog each night, increasing in coverage and severity as pressures rise mid-week.


Forecasts for North America

On Friday evening, severe storms with damaging tornadoes developed around Sioux City, Iowa, and these storms could redevelop later today in parts of Wisconsin, Illinois and western Michigan, northern Indiana. A snowstorm has brought 20-40 cm of snow to parts of the Dakotas and this will move into southern-central Minnesota but snow amounts will be reduced as temperatures will be a bit higher there, wet snow will turn to sleet or rain. Further south, it's likely to be a warm, dry weekend until one reaches the Gulf coast where Karen's rain and wind will arrive by Sunday. Western regions will see increasing cloud followed by rain. My local weather on Friday was cloudy with some sunny intervals and a high near 14 C.

Monday, 7 October, 2013

Forecasts for Ireland

TODAY ... Continuing warm with some risk of locally heavy showers across the far north, isolated showers elsewhere but also some hazy sunshine at times, a more organized band of heavy showers is likely to move through north Connacht, Ulster and north Leinster late in the day, bringing about 5-10 mm rainfalls there. Highs 18-21 C.

TONIGHT ... Showers continuing in parts of the north, otherwise mainly partly cloudy and dry with isolated showers possible, winds picking up from a westerly direction 30-50 km/hr, lows 7-10 C.

TUESDAY ... Breezy, cloudy with sunny intervals (more frequent in south), turning somewhat cooler (winds W 40-60 km/hr), a few showers mainly in northern regions, and highs 15-18 C.

WEDNESDAY ... Considerably cooler with moderate northerly breezes stronger over east Ulster and Leinster where 30-50 km/hr at times, isolated showers and highs 11-14 C although could reach 16 C near south coast.

THURSDAY-FRIDAY ... Sunny intervals each day with highs 12-16 C, cold at night under mainly clear skies with some fog patches, lows 0-4 C. Moderate north to northeast breezes near Irish Sea coasts. Rather light northeast winds elsewhere.

OUTLOOK ... Somewhat milder again (more so at night than daytime) in east to southeast breezes, lows 4-7 C and highs 13-17 C. Some risk of drizzle or light rain spreading into south late weekend or next week. Eventually a milder southerly flow is likely to return.


Forecasts for Britain

TODAY ... Showers heavier in Scotland and parts of northern England (10-20 mm rainfalls), but some parts of southern England and Wales remaining dry with sunny intervals. Highs about 22 C in parts of south, 15-18 C in Scotland.

OUTLOOK ... Turning cooler in stages with strong northerly winds developing in eastern regions mid-week. Similar temperature trends to Ireland, somewhat stronger northwest to north winds mid-week.


Forecasts for North America

Rain or showers with some thunderstorms moving further east to reach large cities of east coast later today. Sporadic heavy showers from remnants of Karen moving inland throughout the southeast U.S. Mild and dry across much of the west as rain spreads into north-central B.C. My local weather on Sunday was sunny with increasing high cloud, highs near 19 C.

Important: Please note legal disclaimer which can be seen at bottom of post 2565 dated 24 July 2012.

Wednesday, 9 October, 2013

Forecasts for Ireland

TODAY ... Considerably cooler with moderate northerly breezes stronger over east Ulster and Leinster where 30-50 km/hr at times, isolated showers across the north eventually reaching central counties by afternoon, and highs only 11-14 C for most, although the mid-day temperature could reach 16 C in parts of Munster and south Leinster, as some sunny intervals will develop in the south this morning. Winds becoming quite gusty near showers by mid-day.

TONIGHT ... Cloudy with clear intervals, isolated showers dying out, rather breezy especially near north and east coasts, as winds veer gradually into the NW to N at 30-50 km/hr. Lows 4-7 C.

THURSDAY ... Sunny intervals, more frequent cloudy spells in north and east, cool with moderate N to NE winds, 30-50 km/hr, highs 11-14 C milder in west and south.

FRIDAY ... Sunny with cloudy intervals, more frequent cloud in parts of the southeast, moderate northeast winds although lighter and more variable in west Ulster and north Connacht ... morning lows 0-4 C, afternoon highs about 12-16 C with the milder values in northwest counties.

WEEKEND OUTLOOK ... Cloudy with some sunny breaks, these more frequent in west Ulster and north Connacht, slight risk of showers or intervals of light rain in parts of the southeast, but many places could remain dry until Sunday afternoon or evening when a more widespread light rain or drizzle could develop in light east winds. Lows 7-10 C and highs 12-16 C. Rainfall estimates at this early stage are quite uncertain, it could be trace to 3 mm amounts or somewhat heavier in places (5-15 mm possible inland south, but not certain).

FURTHER OUTLOOK ... Temperatures will likely edge back up a degree or two and will therefore return to the above normal category as normal values tend to fall about that much each week at this time of year. Some highs of about 18 or 19 C are possible once winds turn more southerly again. There will also be a chance of heavier rainfalls returning.


Forecasts for Britain

TODAY ... Variable cloud, bands of showers developing in central and northern regions, turning colder by afternoon ... highs in south near 18 C, central 15 C and north 12-14 C. Winds becoming NW 40-60 km/hr.

TONIGHT ... Windy, showers, cold. Lows 4-7 C.

THURSDAY-FRIDAY ... Variable cloud, some sunshine at times in west and north, showers becoming more frequent then turning to steady rain in parts of eastern England, later southern England, highs generally near 12 C. Strong northeast winds developing in parts of east and inland south.

SATURDAY-SUNDAY ... Cloudy, drizzle or light rain in parts of south, east winds and highs 14-17 C.


Forecasts for North America

The remnants of Karen are now off the Carolina coast and heavy rain will move north into southern Virginia today and as far north as Long Island and New Jersey, Pennsylvania by tonight and Thursday, accompanied by strong east winds 50-80 km/hr. Highs of about 15 C can be expected in this marine flow, but the warm dry spell will continue further north and west with dense fog widespread under calm conditions at night. Highs of 23-27 C will continue for several more days. It has also warmed up considerably in parts of the west as the storm track there has shifted well to the north, but rain has spread inland over most of British Columbia. My local weather on Tuesday was partly cloudy with highs near 15 C.

UPDATE _ Friday 11 October 0600h
_________________________________

MTC will be away from the internet over the weekend. This morning's updated forecast basically follows on from the above posted yesterday. Today should become quite pleasant in most regions once the morning chill is overcome by sunshine. The best temperatures of 14-15 C are likely to be recorded in places such as south Donegal and west Mayo, possibly parts of Clare and Kerry, west Cork and Limerick, where a land breeze downslopes a little over local hills.

I will be in a remote location for the next 72h and unable to log in, so perhaps someone will step in and post a forecast or two.

Anyway, the winter and its more interesting weather will come soon enough. Have a pleasant weekend, I hope to enjoy a change of scenery (back to the mountains).

Tuesday, 15 October, 2013

Forecasts for Ireland

TODAY ... Rain will spread rather slowly northeastward across west Munster reaching parts of Connacht and Leinster by this evening. Elsewhere, some morning fog or low cloud may clear for a time but then more cloud will spread in. Winds will increase gradually from the southeast to reach 30-50 km/hr in exposed locations. Highs 14-16 C and rainfall amounts in southwest about 10 to 15 mm.

TONIGHT ... Rain may become rather heavy at times with some thunder towards morning, with heaviest amounts from Connacht to south-central Leinster, 10-20 mm. Lows about 10-12 C.

WEDNESDAY ... Periods of rain will continue rather heavy with thunder at times in Leinster, Ulster as more showery and variable conditions spread into Munster and Connacht. Further rainfalls of 15-30 mm possible. Highs about 15 to 17 C mildest inland southwest. Winds veering from E-SE 30-50 km/hr to SSW 25-45 km/hr although some higher gusts possible.

THURSDAY-SUNDAY ... This period will be mild and showery with winds generally from a southerly direction, sometimes increasing to 40-60 km/hr. Highs will be generally around 15-16 C and overnight lows not much cooler than the daytime highs, 9-12 C. Total rainfalls of about 20-30 mm likely.

OUTLOOK ... Very mild to start next week with highs 16-18 C, then returning to low to mid teens with showery conditions frequent.


Forecasts for Britain

The overall trends will be similar although today, there are more widespread showers across much of England and Wales, then tonight and Wednesday morning, some eastern sections of England will be under the dry slot now present in eastern Ireland. Other than those details, the trends will be similar and temperatures will generally average 2-3 C deg above normal.


Forecasts for North America

The west coast will continue to enjoy mild and sunny days and crisp, frosty nights under high pressure. As the flow amplifies, much colder air is moving south into central Canada and will reach the northern plains, western Great Lakes and Midwest U.S. by tonight and Wednesday, dropping temperatures into the 7-12 C range (2-5 C in parts of Canada). Relatively warm conditions prevail further east and across most of the southeast and south central states, with some rain lingering near the Long Island and New Jersey coasts. A possible tropical storm is being monitored south of Bermuda. Meanwhile, my local weather on Monday was sunny and about 14 C.

Saturday, 19 October, 2013

Forecasts for Ireland

TODAY ... Partly cloudy with occasional showers or intervals of heavy rain as waves of moisture are moving north but rainfalls are likely to be heavier in Leinster and east Ulster (15-25 mm potential with afternoon thunder possible), showers not as heavy further west but in some isolated cases may also be heavy, but some brighter intervals also possible. Highs generally 16-18 C. Moderate SSE winds 35-55 km/hr.

TONIGHT ... Foggy, very mild, further showers (5-10 mm), lows 11-15 C.

SUNDAY ... Showers at times, turning to heavy rain in the south by evening. Winds moderate southerly 35-55 km/hr with some higher gusts in west by late afternoon and evening, and highs 14-17 C. Rainfalls 15-30 mm.

MONDAY ... Windy, rain (heaviest across southeast early in the day) tapering to showers, some clearing later, gusty SW winds easing. Highs near 15 C. Rainfalls 5-15 mm except 15-25 mm southeast.

TUESDAY ... Further bursts of heavy rain and very mild, lows 11-14 C and highs around 15-16 C.

WEDNESDAY ... Showers more isolated and some sunny intervals developing, not quite as mild. Lows 7-9 C and highs 11-15 C coolest in Connacht and west Ulster.

THURSDAY to SATURDAY will see another pulse of moisture and warmth heading northeast across Ireland, timing somewhat uncertain from model spread but expect about two days of wet weather near end of the week with highs 14-16 C.

FURTHER OUTLOOK ... The last week of the month also looks very mild and could even feature some record warmth at times in a southwest flow.


Forecasts for Britain

TODAY ... Further showers and bursts of heavier rain in some western regions, highs 17-20 C.

OUTLOOK ... The same very mild and showery pattern will prevail in Britain as in Ireland, timing of most rain and wind events about the same or with a short lag time but heavier showers and stronger winds mainly confined to western and northern regions but also parts of south. Tuesday could see locally very heavy rainfalls and thunderstorms in south central England.


Forecasts for North America

A fresh batch of colder air is streaming south behind a showery disturbance now located in the lower Great Lakes and Ohio valley. This front will reach the east coast late this afternoon but out ahead it will be partly cloudy and 18-20 deg C. Highs closer to 10 C will be the rule in the Midwest and even closer to freezing further north where a snowfall is expected in parts of Manitoba and northern North Dakota. Further west, the warm and dry pattern continues with extensive morning fog that in some places is very slow to disperse even at mid-day. My local weather on Friday was foggy to start, sunny mid-day then foggy again this evening. The high was 14 C -- we have very warm air aloft creating a very strong inversion.

Sunday, 20 October, 2013

Forecasts for Ireland

TODAY ... Showers at times, one or two heavy and thundery, but also some dry intervals and even a bit of sunshine, before afternoon cloud and showers turn to heavy rain in the south by evening. Winds gradually increasing to become moderate southerly 35-55 km/hr with some higher gusts in west by late afternoon and evening, and highs 14-17 C. Rainfalls 10-20 mm.

TONIGHT ... Heavy rain at times across the south and east although this will tend to move rather slowly once north of a Dublin-Galway line, thus rainfall amounts 10-20 mm south, 3-6 mm north and mostly later overnight there. Very mild with lows 10-13 C.

MONDAY ... Windy, rain (heaviest across southeast early in the day) tapering to showers, some clearing later, gusty SW winds easing. Highs near 15 C. Rainfalls 5-15 mm except 15-25 mm southeast.

TUESDAY ... Further bursts of heavy rain and very mild, lows 11-14 C and highs around 15-16 C. Rainfall potential 15-30 mm.

WEDNESDAY ... Showers, still heavy in Leinster during the morning, otherwise more isolated with some sunny intervals developing, not quite as mild. Lows 7-9 C and highs 11-15 C coolest in Connacht and west Ulster. Further rainfalls of about 5-10 mm east mainly.

THURSDAY ... Some sunshine to start, increasing cloud, morning lows 4-8 C for most, 10 C south coast, 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 central counties, highs 14-17 C. Winds becoming southerly 30-50 km/hr.

NEXT WEEKEND OUTLOOK ... Rain should begin to ease Saturday morning and there could be some brighter spells by afternoon with highs 12-14 C, fresh westerly breezes developing, then Sunday will be a partly to mostly cloudy day with a few showers in fresh backing southwesterly winds, highs 12-14 C.

FURTHER OUTLOOK ... It seems likely that the last few days of the month will be very mild again but it could turn windy or even stormy around the start of November. Highs may be into the mid-teens at times.

I will pause the Britain and North America forecasts for one day as nothing much has changed from the previous report, even my weather is about the same as the previous day, morning fog and afternoon sunny spells with highs in the 14-17 C range. Some dense fog persisted all day closer to the coast.

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.

Thursday, 24 October, 2013

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.

Saturday, 26 October, 2013

Forecasts for Ireland

ALERTS for strong winds in northern, central counties on Sunday, some gusts to 110 km/hr possible ... ALERT for heavy rainfalls over the next 48h especially across the south where 30-40 mm may accumulate by Monday morning ... TRAVEL ALERT for severe winds to 140 km/hr in parts of southern England, Channel and northern France on Monday -- this storm will have only indirect impacts on Ireland (see forecasts).

TODAY ... Breezy, showers or periods of rain redeveloping around sunrise in the west to mid-morning east, with 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 but squally showers may develop in north.

TONIGHT ... Showers or periods of rain, increasing SW winds to 70 km/hr and mild, lows 6-10 C. Further rainfalls of 5-10 mm.

SUNDAY ... Partly cloudy, showers (5-15 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, some gusts to 110 km/hr in well-exposed locations) with lows 7-9 C and highs about 13 or 14 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

TODAY ... 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 to near 18 C southeast.

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.

Monday, 28 October, 2013

Forecasts for Ireland

TODAY ... Gusty winds will redevelop this morning from a west to northwest direction, backing to southwest as troughs develop across most regions with gusts to perhaps 70-90 km/hr, although most of the time speeds will be in the range of 40-60 km/hr. Further showers with some hail and the slight risk of thunder (inland southwest most at risk) will bring 5-10 mm today, with highest temperatures 10-13 C.

TONIGHT ... Gradual clearing, showers more confined to Atlantic coasts then dying out there as well, moderate west to northwest winds. Lows 4-7 C.

TUESDAY ... Variable cloud, showers more isolated and some places dry, moderate west winds backing to southwest, highs 11-13 C.

WEDNESDAY ... Showers or periods of rain, windy, mild. Lows 5-7 C and highs 12-14 C. Rainfalls 5-10 mm.

THURSDAY ... Some dry weather in north 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.


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.

Wednesday, 30 October, 2013

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).
