Forecasts for Ireland

TODAY ... Showers and thunderstorms becoming widespread, covering most of the west from the Atlantic, with isolated showers reaching parts of east Ulster and north Leinster from the Irish Sea. By mid-day all but a few places in the southeast are likely to see 10-20 mm rain with some storms becoming severe in places (most likely Clare, Galway and Mayo as well as nearby parts of other counties). Continuing rather warm and humid, with afternoon highs 22-25 C. Turning noticeably fresher in west Munster during the afternoon and evening. Moderate southerly winds 15-30 km/hr but risk of higher gusts near storms, as well as hail and torrential downpours locally bringing flash flooding to a few locations.

TONIGHT ... Showers dying out gradually with fog or mist developing, still rather warm except in parts of the southwest, lows generally 14-17 C although closer to 12 C in southwest.

WEDNESDAY ... Variable cloud, showers, much cooler in west and somewhat cooler in east where more sunshine could develop in south to southwest winds of 20-40 km/hr. Lows 12-15 C and highs about 18-23 C. Some heavy or severe storms could develop in a few central locations, most likely in the western half of the country. Heavy rain may also develop in Leinster during the evening and overnight into Thursday morning. Some rainfalls of 20-25 mm possible, widespread 10-15 mm should begin to ease the current drought.

THURSDAY to MONDAY (29th) ... Partly cloudy to overcast and continuing closer to seasonal normal temperatures with frequent showers at times. Further rainfalls of about 20 mm during this period will bring further relief to lingering drought. Highs generally 17-24 C (with the warmest readings southeast) with lows about 8-11 C.

FURTHER OUTLOOK ... The month will likely end with rather unsettled weather then a gradual warming trend is likely to follow around the first few days of August but no indications yet of a return to hot weather, probably if that comes it will be closer to two weeks away.

Forecasts for Britain

TODAY will be warm and humid with widespread showers and thunderstorms, which could become heavy or severe. Highs 23-27 C over most of the south, 21-24 C further north, although 18-20 C near most coasts where it could be rather foggy at times.

The outlook is similar to Ireland, widespread heavy showers and thunderstorms on Wednesday, followed by somewhat cooler weather although southeast England will stay rather warm in the 24-29 C range most days, but highs will trend to about 20 C in northwest England and Wales, 18 C in Scotland later this week. Frontal boundaries may be rather weakly defined which suggests daily cycles of afternoon and evening isolated thunderstorms in central regions mostly. Heat may try to return to the southeast around Friday which could set off some very heavy thunderstorms around London.


Forecasts for North America

An active cold front is developing and could bring severe storms to the Midwest and Great Lakes later today, while it remains warm and humid further east and south with only isolated storms. Considerably cooler air is moving south from central Canada into the upper Midwest and parts of the northern plains and eastern prairies, with the front also pushing west into the central Rockies. Warm and dry further west.

My local weather on Monday was sunny with cloudy intervals and warm with highs near 25 C.

Thursday, 25 July, 2013

Forecasts for Ireland

TODAY ... Some heavy showers and developing thunderstorms in a north-south line in central counties will drift slowly northeast, bringing 10-20 mm rainfalls to parts of inland Leinster, east Connacht and later central and east Ulster. By afternoon these showers are likely to be more confined to east Ulster. Partly cloudy to sunny conditions should prevail in some southeastern counties and much of the west, with just a few isolated showers separate from the feature already described. This more settled weather will push east to replace the line of showers. Highs for most will be 19-23 C but within the slow-moving line of heavy showers temperatures will be around 16 C, and some outer coastal districts in the southwest could be held to about 18 C by sea breezes.

TONIGHT ... Further showers, some becoming heavy, in Ulster. Partly cloudy elsewhere with one or two isolated showers and a slight risk of a brief thunderstorm. Misty towards dawn with lows 13-16 C.

FRIDAY ... Intervals of cloud and sunshine, isolated showers, and afternoon highs 19-23 C.

SATURDAY ... Showers with isolated thunder, heavy at times in parts of south and west. Partly cloudy for most of the day in east and north, showers arriving later. Highs near 20 C. Rainfalls of 10-20 mm south and west.

SUNDAY ... Variable cloud, frequent showers and risk of a thunderstorm, rather warm and humid with highs near 21 C. Rainfalls near 10 mm.

FURTHER OUTLOOK ... Monday is likely to remain unsettled, but there are signs of a gradual warming trend around the end of the month and perhaps a return to very warm weather at times in August.


Forecasts for Britain

TODAY will continue mostly cloudy with some sunny breaks, widespread showers and a few thunderstorms, 10-15 mm rainfalls for many, with highs 23-26 C over most of the south and central regions, 18-21 C further north.

Friday could see some sunshine in places but heavy showers and severe storms could develop across the south and east as hot, humid air tries to push back from France into London and Kent, Surrey and Sussex. The weekend will then turn cooler in stages with severe storms possible in the southeast on Saturday, and occasional showers elsewhere but heavier rain into western Scotland. Hot weather could return to at least southern Britain around the end of July and first few days of August. Basically, the pool of somewhat cooler air already present to the west of Ireland never makes much eastward progress and is squeezed out of the picture by returning high pressure from the south, and in fact the interruption to the heat wave is almost negligible in southeast England. Further east into central Europe the pattern remains hot and largely dry with scattered outbreaks of thunderstorms.


Forecasts for North America

The pattern is basically warm and humid almost everywhere now with rather weak frontal systems that can bring isolated heavy storms. The most significant front is now moving east from the high plains and central prairies towards the upper Midwest. Hot and dry conditions prevail closer to the west coast. Meanwhile, T.S. Dorian will make steady progress west for several days and could become a player for the east coast of the U.S. later next week as it tracks north of the Caribbean region towards the Bahamas.

My local weather on Wednesday was once again sunny and warm with highs near 26 C. The official weather station for Vancouver at the airport has seen no rain since 28th of June although I've seen a bit here (less than 1 mm).

Saturday, 27 July, 2013

Forecasts for Ireland

TODAY ... Showers with isolated thunder, heavy at times in parts of south and west. Partly cloudy for most of the day in east and north, showers arriving later there, if at all. Highs near 20 C. Rainfalls of 10-20 mm south and west.

TONIGHT ... Partly cloudy to overcast, a few showers continuing in west, warm and muggy with lows about 14-17 C.

SUNDAY ... Variable cloud, frequent showers and risk of a thunderstorm, rather warm and humid with highs near 21 C. Rainfalls near 15 mm on average and a few spots closer to 30 mm with risk of spot flooding. The heaviest rainfalls are likely to occur late in the day in central counties but all regions will be prone to some heavier falls locally.

MONDAY ... Heavy showers or thunderstorms at times, with a gradual clearance from west to east late in the day. Rainfalls 10-30 mm. Morning lows about 14 C and highs 18-21 C.

TUESDAY ... Some sunny intervals, followed by increasing cloud, showers or thunderstorms, some heavy or severe, rather warm and humid. Highs 21-24 C.

OUTLOOK ... The rather warm and unsettled regime of southerly winds could persist for about a week but there remains a chance of even warmer weather developing which would generally push the storm risk mainly to the west and north again.

Forecasts for Britain

TODAY will bring widespread heavy thunderstorms as hot, humid air over the southeast and most of France interacts with a frontal wave that will develop this morning over northern France and then move up into Britain this afternoon. Some very heavy rains are indicated in south central and east Midlands regions, 25-50 mm potential. Highs will range from the low 20s in the rain and further north, to 24-27 C southeast and 27-30 C possible as 32 C temperatures will be established across the Channel.

SUNDAY will become cooler with showers and sunny intervals, highs 18-23 C.

Beyond that, the trends should be similar to Ireland although with higher temperatures in general and a return to hot, dry weather will likely develop fairly early in August for southeast England.


Forecasts for North America

The most prominent feature will be a strong cold front advancing east through the Great Lakes, Ohio valley and central plains states leading rather cool (for late July) air from central Canada into the Midwest. Highs of only 15-18 C will be recorded in parts of the upper Midwest and northern plains, eastern prairies and much of the upper Great Lakes. Ahead of the front, widespread storms will develop across the mid-Atlantic states in a southeasterly flow and it will be humid with highs near 25 C. The west, meanwhile, continues to see hot, dry weather with just a shallow incursion of cooler air from the Yukon into northern B.C. and Alberta setting off a few storms near the Peace River region.

My local weather on Friday was sunny and hot with highs near 30 C inland and mid-20s closer to the ocean.

Monday, 29 July, 2013

Forecasts for Ireland

TODAY ... Heavy showers or thunderstorms at times in north, more widely dispersed showers for south, with a gradual clearance from west to east mid-day west, afternoon east. Some spot flooding possible in north Connacht and west Ulster around Donegal Bay this morning to mid-day. In general, rainfalls 10-20 mm north and 3-7 mm parts of south, east, with highs 18-22 C.

TONIGHT ... A few clear intervals, isolated showers in a few locations, lows about 14 C.

TUESDAY ... Some sunny intervals, followed by increasing cloud, showers or thunderstorms, some heavy in parts of west Munster, although it may remain largely dry further east ... rather warm and humid. Highs 21-24 C.

WEDNESDAY ... Partly cloudy, warm and humid, occasional showers or thunderstorms, highs near 23 C.

THURSDAY ... Frequent showers and possibly some heavy rainfall in places, turning a bit cooler and fresher especially in Connacht, highs 18-21 C.

OUTLOOK ... Model guidance is inconclusive but I suspect that warmer weather is about to return in stages, and perhaps rather quickly once this mid-week disturbance pushes through, so look for highs into the mid 20s by about the weekend or early next week.


Forecasts for Britain

TODAY ... Warm and humid with a few isolated showers and thunderstorms, highs about 24 C for most, 18-21 C Scotland.

OUTLOOK ... Similar trends to Ireland with heavy rains at times central and northern regions towards Thursday. Heat likely to return gradually by about next weekend and possibly near 30 C in a week to ten days.

Forecasts for North America

The recent very cool spell is moderating in the Midwest and Great Lakes regions as temperatures recover to about 24 C today, otherwise, the patterns remain about the same in other regions with hot and dry conditions over most of the west now extending into central portions of the U.S. ... Forecasters were ready to write off Dorian but now it appears that "he" may recover somewhat and return to tropical storm status in the Bahamas by tonight or Tuesday.

My local weather on Sunday was sunny and quite warm with afternoon towering cumulus to the north, dry here (30 days without rain now) ... high was 24 C.

Wednesday, 31 July, 2013

Forecasts for Ireland

ALERT for heavy rainfalls today and tomorrow, heaviest in parts of Connacht, Ulster and nearby parts of Munster, Leinster, while the southeast (after this morning) may remain relatively dry. Some spot flooding at times and some severe thunderstorm activity each day from now to about Thursday. Dublin remains somewhat on the margins of this heavier rainfall and severe storm zone, risks increase to north and west.

TODAY ... Cloudy, warm and humid, occasional showers or thunderstorms, with some heavy falls of 20-40 mm possible by end of the day in the north and parts of the west, closer to 10 mm southeast, 20 mm Dublin. Highs near 20 C except 22-23 C in the inland southeast where some hazy sunshine could break through the overcast this afternoon. The area of rain currently drifting north will likely weaken somewhat then redevelop early afternoon from west to east across Connacht and Ulster, north Leinster, while a second area of possibly heavy thunderstorms could develop around Laois and affect parts of the Dublin-Wicklow region this afternoon. Despite all this mention of rain, there could be some decent dry intervals in some locations particularly the southwest and west by afternoon.

TONIGHT ... Rain tapering to drizzle, isolated thundershowers possible, very muggy with lows 14-17 C.

THURSDAY ... Frequent showers and possibly some heavy rainfall in places, risk of severe storms greatest in Connacht, Ulster and north Leinster, nearby parts of west-central Munster. Potential for 15-30 mm rain, wind gusts to 70 km/hr with some storms, and 2 cm hail, highs 18-21 C. Moderate south to southwest winds except for the gustier intervals around storms 30-45 km/hr.

FRIDAY ... Cloudy with sunny intervals, relatively isolated showers with hit or miss 2-5 mm rainfalls, highs near 18 C.

SATURDAY ... Occasional sunny intervals with just a few isolated showers, warm with highs near 22 C.

SUNDAY ... Increasing cloud east, warm with highs 22-24 C. Showers and thunderstorms likely in the west, reaching central counties mid-afternoon but eastern counties towards evening.

FURTHER OUTLOOK ... The following week looks somewhat improved with higher pressures building in and temperatures staying near 21-23 C if not slightly warmer at times.


Forecasts for Britain

TODAY will become cloudy with showers developing, warm and humid, highs near 23 C.

THURSDAY-FRIDAY will bring widespread heavy thunderstorms and periods of rain to west and north, but will be hot and humid in the east and south until late Friday when the storms may finally arrive. Highs west and north 20-23 C but 29-32 C east and south.

OUTLOOK is for warm and dry weather once this frontal system moves through early Saturday, with a brief interruption in some western and northern districts around Monday. Highs will average about 25 C.

Forecasts for North America

A rather bland pattern now prevails across the continent with some showers or thunderstorms approaching the mid-Atlantic states from the west, near normal temperatures in most eastern and central regions. Hot and dry conditions prevail further west, with gradual development of isolated storms over mountain ranges today leading to more widespread storms on Thursday. As I'm travelling on Thursday in B.C., I hope to get some good views of storms and possibly some pictures to follow on Friday.

My local weather on Tuesday was sunny and very warm, highs near 26 C. The month of July remains bone dry locally and should end that way although it could rain just around midnight. This is rather unusual but not unprecedented, in 1951 there was a 58-day dry spell, this one is now 33 days long.

UPDATE _ Friday, 2 August, 2013 _ 0830h
_____________________________________

Forecast remains essentially the same as given yesterday ... I will post a more complete version as usual on Saturday morning, but for today, just adding this more detailed look at today's forecast ...

TODAY will start out mostly cloudy in most regions and partly cloudy in east and south coastal districts. Strong southwest winds with gusts to 70 km/hr are likely to persist most of the day in Connacht and west Ulster with some squally showers at times. Highs will be about 17 C there. In most other regions, more moderate southwest winds gusting to 50 km/hr with occasional showers developing, one or two becoming thundery with the risk of hail and gusty winds, most likely places to see more severe storms would be in a zone extending from Cork in the southwest to Meath in the northeast. Highs will range from 19 to 21 C in the larger part of the country.

TONIGHT should see most of the showers and stronger wind gusts moving away to the north or dissipating, leading to some clear intervals and lows about 8-11 C. I was asked about the Oxygen event and basically would say expect a bit of everything later today and overnight, a fairly decent day tomorrow with slight risk of a shower. Not sure how long into the weekend the question is valid but wet weather appears likely by Sunday mid-day to evening lasting into part of Monday (in eastern Ireland in general, for the west the timing would be earlier).

Have a great weekend in any case. Watch the thunderstorm thread here for updates on storm potential later today. I don't expect to be awake much past 0930h having just emerged from a deep sleep following a long drive, and feeling like a second deep sleep is now required. On our way here, we saw a number of developing thunderstorm cells but more active weather seemed to be further south than our route took us, maybe Friday will bring some more inspiring skies for pictures, today had a veil of higher cloud so that you couldn't see much of the storm structure anyway, but there was some lightning over one of the three ranges that we crossed to get here (here being south central B.C.).

UPDATE _ Sunday 4 August _ 0845h
__________________________________

Just a brief update on the approaching rainfall for the south ... the southeast, notably Wexford, will see periods of moderate rain by this afternoon with heaviest amounts near 20 mm, but further north it may be light and patchy reaching about as far north as Limerick to Dublin at some point this evening to midnight, however amounts away from the southeast will be light (2-5 mm) and large portions of Connacht and Ulster could remain dry or see separate light showers giving a trace to 2 mm. The last of this rain should be ending around 0900h Monday in Dublin and Wicklow, then the rest of Monday should be fairly dry in most areas with just isolated showers.

At my current location, Saturday was a mainly sunny and very warm day (about 28 C and humid) with showers gradually building up in all four quadrants over mountains, then these appeared to merge into a brief downpour oddly without thunder, with very interesting skies including a bright rainbow. Hope to post a picture or two during the next day or two.

SATURDAY ... Partly cloudy to overcast, risk of some occasional drizzle or light rain in some parts of west and north but generally a dry day, highs 17-19 C.

SUNDAY ... Mixture of cloud and sunshine in most areas, mostly cloudy north, where some drizzle or light rain possible at times. Lows 7-10 C and highs 17-20 C best in the inland southeast.

MONDAY ... Partly cloudy, slight chance of showers mainly west and north, lows about 6-9 C and highs 16-18 C.

TUESDAY ... Some sunny breaks east during morning but generally clouding up with rain later, looks like about 5-10 mm ... lows 7-10 C and highs 17-19 C.

WEDNESDAY ... Potential for heavy showers and perhaps a few thunderstorms, lows 11-13 C and highs 17-20 C.

FURTHER OUTLOOK ... The mid-week unsettled spell should gradually improve to more settled conditions and near-average temperatures. There are some signs of warmer weather returning later in August.

Sunday, 11 August, 2013

Forecasts for Ireland

TODAY ... Rather cloudy in general with a few sunny intervals developing mostly in central counties, light showers at times in north and isolated showers possible elsewhere. Highs 17-20 C.

TONIGHT ... Partly cloudy, some partial clearing but views of the Perseids may be interrupted at times by passing cloud, lows 8-11 C.

MONDAY ... Partly cloudy to sunny, relatively warm with highs 18-21 C. Evening and overnight clear intervals more frequent in east.

TUESDAY ... Increasing cloud, warm, lows 8-11 C and highs 19-22 C with rain arriving in the southwest around evening.

WEDNESDAY ... Rather cloudy, warm and humid, showers and risk of a thunderstorm across parts of west, central and inland north ... morning lows 11-14 C and highs 21-23 C for most, 19-21 C north.

THURSDAY ... Showers and a few thunderstorms, lows 12-14 C and highs about 21 C.

OUTLOOK ... Temperatures are likely to improve further once the fronts clear on Thursday, and we could be seeing a subdued warm pattern not quite as hot as the June or July episodes, but in the 23-25 C range, before too long.


Forecasts for Britain

TODAY will become partly cloudy with isolated showers, highs 21-23 C.

The pattern will continue to be quite similar to Ireland in this mobile west to southwest upper flow, with the main difference being timing of frontal passages about 6-9 hours later in general.


Forecasts for North America

Since our last forecast for North America, trends have been generally rather bland and near normal in most regions, although very wet at times in the south central U.S. That trend is somewhat in decline now but there are widespread thunderstorms across the north central and northwest U.S. extending into parts of southern B.C., becoming heavy at times. Temperatures are generally rather close to seasonal normals but it's anomalously warm in the subarctic regions of Canada where 25-30 C temperatures extend right to the shores of the Arctic Ocean and 21-24 C in some portions of the arctic islands.

My local weather on Saturday was cloudy to start, with isolated showers, then sunny by afternoon and about 25 C.

Tuesday, 13 August, 2013

Forecasts for Ireland

TODAY ... Cloudy with a few mid-day and afternoon brighter intervals, mostly in south central counties, rather warm and muggy, highs 19-22 C with a few outbreaks of mid-day rainfall across the north and east, then a few more showers arriving in the southwest around evening. Rainfalls by midnight in the range of 3-5 mm in most places.

TONIGHT ... Cloudy, misty, warm or mild, lows 11-14 C. Some patchy drizzle mostly across the south.

WEDNESDAY ... Rather cloudy, warm and humid, showers and slight risk of a thunderstorm across parts of west, central and inland north with highs about 21-23 C for most, 19-21 C north. Some places dry but a few rainfalls of 5-10 mm possible.

THURSDAY ... Showers and a few thunderstorms (slight risk some will become severe), lows 12-14 C and highs about 21 C. Breezy to windy by afternoon (veering SSW to WSW 30-50 km/hr) and clearing gradually. Rainfalls 10-15 mm.

FRIDAY ... Partly cloudy to sunny, highs about 21 to 23 C.

WEEKEND OUTLOOK ... Showers arriving Friday night should clear east Saturday morning, then a breezy and partly cloudy weekend with near normal temperatures (highs 18-21 C) warming to the low to mid 20s by the following week, with mainly dry conditions the prevailing theme.


Forecasts for Britain

TODAY will be partly to mostly cloudy with a few showers mainly in western and northern counties. Highs 20-23 C highest in the inland south.

The trend from tomorrow on will be similar to Ireland with some of the rainfall events about six hours later on average, as fronts continue to sweep east from the Atlantic. This means that Thursday could see some heavy or severe afternoon thunderstorms in parts of Wales and central England.


Forecasts for North America

Unseasonably cool air is moving south through the Great Lakes and Midwest regions behind an area of heavy showers and thunderstorms that will reach most of the larger cities on the east coast during the day. Highs only 15-19 C behind this front, 20-24 C during its passage. Hot and humid further south with widespread heavy thunderstorms likely. Meanwhile the northern plains states and parts of the central plains are also rather cool under the core of high pressure associated with the northerly winds further east, highs will reach about 26 C after quite a cool start. A frontal wave moving across Alberta and Saskatchewan is bringing severe storms overnight and will redevelop this afternoon in Manitoba and North Dakota. The southwest remains seasonably hot with isolated thunderstorms mainly over higher terrain. The west coast is generally clear except north of Vancouver where rain is developing for the overnight hours and later today, some heavy falls may occur but it should remain largely dry in the Pacific northwest states with isolated storms.

My local weather on Monday was partly cloudy at first, sunny by afternoon, and around 24 C.

Thursday, 15 August, 2013

Forecasts for Ireland

TODAY ... The morning could remain dry and relatively bright in eastern counties, as heavy showers and a few thunderstorms (slight risk some will become severe) advance into the west then spread across the east by afternoon, with highs about 19 C west to 21 C east. Breezy to windy by afternoon (veering SSW to WSW 30-50 km/hr) and clearing gradually in parts of the north and west, as more showers develop across the south. Rainfalls 10-20 mm for most, heavier amounts likely to run from south Clare and north Limerick northeast towards Meath, Louth, Cavan and Down. Thunder may be rather isolated at first, but we will be watching for development around Offaly-Laois-Westmeath-Meath-north Kildare-west Dublin by mid-afternoon. Heavy downpours are more certain.

TONIGHT ... Showers ending around midnight in east, followed by clearing, gusty WSW winds 30-50 km/hr, lows of 11-13 C.

FRIDAY ... Partly cloudy to sunny, breezy (WSW 30-50 km/hr) with highs about 19 to 21 C. Some isolated showers later in the day mostly in Connacht and west Ulster, then a more general and heavier rain by evening, lasting overnight into Saturday morning with lows of 12-15 C.

SATURDAY ... Showers arriving Friday night should clear east during the morning, winds increasing to westerly 40-70 km/hr, lows 12-15 C and highs 17-20 C. Rainfalls (mostly early in the day) about 10 mm.

SUNDAY ... Partly cloudy and somewhat cooler with further showers, mostly west and north, highs 16-19 C. Quite breezy at times (WNW 40-60 km/hr), with a rather autumnal feel but this won't last very long. ...

FURTHER OUTLOOK ... Gradually warmer and mostly dry with some chance of overnight showers late Monday night into the daytime hours of Tuesday mainly north of a Galway to Dundalk line, possibly becoming quite warm in the south during Tuesday and then in all regions later in the week with highs into the mid 20s. This warm spell may feature east winds and somewhat cooler readings near the east coast (18-21 C) and warmest weather in west Munster and Connacht (24-26 C). Some models are indicating a rather prolonged warm spell developing and it should be dry and sunny most of that time but details will emerge later.


Forecasts for Britain

TODAY will feature several rounds of heavy showers and the risk of some heavy to borderline severe thunderstorms (most likely to develop inland west) with highs near 22 C south, 17-19 C north.

The trend from Friday on will be similar to Ireland with a dry interval later Friday, showers becoming heavy on Saturday in blustery winds, then a gradual improvement with the possibility of highs reaching 24-27 C later in the week.


Forecasts for North America

It will remain dry and cool in parts of the northeast, Great Lakes with showers advancing into the Midwest from the north-central plains. Very warm and humid with scattered storms in the southeast states, mainly hot and dry in the west, trending to warm and showery in western Canada. The Cape Verde tropical system is now Tropical Depression No. 5 (the next name is Erin), and the Caribbean system may interact with land (the Yucatan peninsula) before reaching tropical storm status (if not Erin, then Fernand) later this weekend in the Gulf of Mexico.

My local weather on Wednesday was cloudy and warm with a rare (for this summer) rainfall of 2-3 mm during the late afternoon, highs near 23 C.

Saturday, 17 August, 2013

Forecasts for Ireland

TODAY ... Showers will be generally rather light and most will clear east during the morning, with winds increasing to westerly 40-70 km/hr, and highs 17-21 C. Rainfalls (mostly before noon except mid-afternoon southeast) about 5-10 mm. Guidance has been cutting back the amounts but it could be a rather persistent light rain in any case for a few hours. Later showers more isolated and hit or miss in nature.

TONIGHT ... Isolated showers mostly confined to northwest coastal regions, breezy to windy and feeling quite cool as lows drop to 7-9 C. Winds continuing blustery from W at 30-60 km/hr.

SUNDAY ... Partly cloudy and somewhat cooler with further showers, mostly west and north, morning lows 7-9 C and highs 16-19 C. Quite breezy at times (WNW 40-60 km/hr), with a rather autumnal feel but this won't last very long. ...

MONDAY ... Frequent sunny intervals, lows 7-9 C and highs 18-20 C.

TUESDAY ... Showers and chance of a thunderstorm mainly north and west, although some recent guidance is showing most of this rainfall staying offshore except for the immediate shorelines of Donegal Bay then by Tuesday night north Ulster. Some warm sunny intervals developing further south, highs may range from 18 or 19 C north to 23-25 C south. Winds increasing to S-SW 40-60 km/hr.

WEDNESDAY ... Breezy and warm for most, slight chance of morning showers lingering in north before clearing, highs 21-25 C.

OUTLOOK ... Sunny and quite warm mid-week into the weekend, highs generally into the 24-27 C range, some cooling sea breezes mainly east coast but affecting all coasts at times in a rather light and variable wind pattern that will feature east to northeast breezes more frequently than other directions.

Forecasts for Britain

TODAY will become very breezy and further showers or isolated storms will develop mainly in the south and some lighter bands in Wales and central England. Highs 19-22 C south, 16-18 C central and 14-17 C north. Winds about 40-70 km/hr from the west by afternoon.

TONIGHT through SUNDAY and MONDAY should be a largely dry interlude with just a few lingering morning showers in east on Sunday ... breezy and cooler with highs near 18 C.

FURTHER OUTLOOK is for increasingly warm weather with plenty of sunshine next week and the possibility of highs reaching 24-27 C later in the week.


Forecasts for North America

The east will see a warming trend this weekend under sunny skies and highs will reach the 24-27 C range but humidity levels will remain quite low. Further outbreaks of very heavy rain likely in the southeast, and some unusually cool daytime temperatures as a result of cloud and east winds, only 22-25 C in some places. Atlanta had a record low maximum of only 19 C on Friday. Meanwhile the west is heating up and this heat is also covering a good portion of central-western Canada, with cloudy and warm conditions further west near the B.C. coast, and some outbreaks of light rain there. Erin continues to cling to minimal tropical storm status in the central tropical Atlantic, and the potential for Fernand still seems about 50-60 per cent likely for some portion of the Texas coast by about Monday-Tuesday.

My local weather on Friday was partly cloudy, very warm and humid with a few sprinkles of rain and highs near 25 C (the humidity levels are quite unusual conditions for the west coast).

Forecasts for Ireland


TODAY ... Morning cloud and isolated light rain showers will tend to clear to at least partly sunny skies mid-day with increasing higher cloud by afternoon, and highs 18-20 C. A few parts of the west could see 1-2 mm rain but otherwise it should be generally dry.

TONIGHT ... Some clear intervals but mostly cloudy and rather mild with lows about 11-13 C.

TUESDAY ... Mostly cloudy, warm especially in parts of the south where some sunshine could develop at times by afternoon. Mainly dry until late afternoon or evening when some showers are likely in the northwest, spreading across the north overnight. Amounts could be rather slight, 3-7 mm on average, with parts of the south and east remaining dry. Highs may range from 18 or 19 C north to 22-24 C south. Winds increasing to S-SW 40-60 km/hr.

WEDNESDAY ... Some light rain during the morning in parts of north-central to northeastern Ireland early morning, then by late morning becoming partly cloudy, breezy and warm for most, morning lows about 14 C and highs 21-25 C.

THURSDAY ... Some hazy sunshine and rather warm, highs about 22-25 C.

FRIDAY ... Partly cloudy to overcast, some showers developing in southwest, highs 21-24 C.

WEEKEND OUTLOOK ... The models are rather indecisive about the prospects for the weekend at this early stage, the theme appears to be a slight cooling trend with at least isolated showers and possibly heavier showers in some places, with gusty winds indicated on at least one model, but temperature changes may be rather subtle as one warm ridge is replaced by another one after a brief interruption from a weak or possibly moderate trough. Highs are likely to remain close to 20 C then could return to the low or mid-20s at some point next week.


Forecasts for Britain

TODAY ... Mostly cloudy with isolated showers, some sunshine at times mid-day and afternoon in the south and parts of Scotland. Highs 18-21 C.

A similar trend to Ireland will follow with any rain from the Tuesday night or Wednesday weakening frontal disturbance affecting mainly western parts of northern England and southern Scotland.


Forecasts for North America

The general pattern is warm and dry across the northern half of the U.S. and adjacent southern Canada, and quite hot in the central plains states. The southeast remains unsettled and is having a relatively cool and wet summer this year. Meanwhile, Erin has died out and Fernand never managed to develop as a tropical system at all, although there is a circulation and areas of rainfall in the western Gulf.

My local weather on Sunday started out cloudy and drizzly, then became sunny by late afternoon with a high near 21 C.

Forecasts for Ireland


TODAY ... Some scattered outbreaks of drizzle or light rain during the morning in parts of the west, south coast, and east Ulster, then by late morning becoming partly cloudy, breezy and warm for most, although some light rain could persist near the central south coast. Highs inland will respond to any sunshine but will range from 21-24 C, warmest in the inland south and southeast. Highs near most coasts and especially across the north about 19 C.

TONIGHT ... Warm, humid, foggy at times with isolated drizzle mainly near coasts. Lows 14-17 C.

THURSDAY ... Some hazy sunshine and rather warm, highs about 22-25 C. There could still be a few spots of drizzle or mist near some coasts.

FRIDAY ... Partly cloudy to overcast, some showers developing in southwest, some of these becoming heavy at times with risk of thunder, lows about 15 C and highs of 21-24 C, with gusty southwest winds 40-60 km/hr developing.

SATURDAY ... Variable cloud, a few showers, breezy (WSW 30-50 km/hr) and morning lows 9-11 C, highs 19-22 C. Warmer in the southeast inland than most other regions.

SUNDAY ... Partly cloudy, isolated showers, breezy (WNW 30-50 km/hr) with morning lows 8-10 C and highs 20-22 C.

OUTLOOK ... (continued same from yesterday) ... The following week is looking mainly dry and somewhere between normal in temperature and very warm depending on which model has the best handle on the position of the large Atlantic high that all seem to indicate will develop to the southwest or west of Ireland. Some guidance would have us believe that temperatures could reach the mid or even higher 20s but caution is still needed given the spread of solutions.


Forecasts for Britain

TODAY ... Quite warm for most, heavy showers moving through Scotland after largely missing Ireland to the north ... 10-15 mm rain on average in parts of south-central Scotland, but dry for most of Wales, central and southern England. Highs near 25 C in the south but only 15-18 C in the north. Winds rather blustery at times with the northern showers, WSW 40-70 km/hr. Not quite that breezy central and rather light winds inland south.

OUTLOOK ... Warm on Thursday, showers and turning a bit cooler by late Friday and variable over the weekend with showers and gusty west to southwest winds at times, highs abour 27 C on Thursday, 21-24 C rest of the period in south, 17-20 C north.


Forecasts for North America

Warm and dry in Great Lakes, inland northeast and Midwest, trending to hot and humid in central states. A rather strong cold front is moving through the upper Great Lakes but likely won't push very far south of northern Lake Superior. Rain continues to plague parts of the inland southeast where temperatures are slowly recovering from record low values (which in their case would be near normal values for Ireland). Atlanta recently had about four or five days without reaching 80F (27 C) which is very unusual there in August. This colder pool is shallow and does not extend much further west than the Mississippi River, while Texas remains seasonably hot and humid and the southwest also have relatively normal summer heat and isolated storms.

My local weather on Tuesday was pleasant, sunny and about 23 C.

Friday, 23 August, 2013

Forecasts for Ireland


TODAY ... Showers and a few isolated thunderstorms will continue to move east and there may be partial clearing in the west by mid-day, then another interval of cloud with risk of showers developing again later afternoon or evening as the earlier clearing moves through Leinster and east Ulster. Highs should reach 21-23 C during brief sunny intervals, and somewhat gusty southwest winds 40-60 km/hr will gradually develop. Rainfalls of 5-15 mm (soon to be largely finished in central and western counties) heaviest in east Ulster and north Leinster. It's interesting to note that the later (second) feature is not very developed on most guidance beyond mid-level cloudiness but I have a hunch that it may produce some briefly heavy showers too. An update may be required around mid-day for that (affecting west then central counties afternoon and evening).

TONIGHT ... Any showers likely ending before midnight in the east, then a clearing trend with the Moon rising around 11 p.m. to midnight providing a nice skyscape. Lows 9-12 C.

SATURDAY ... Sunny at first then variable cloud, and a few showers developing, breezy (WSW 30-50 km/hr), highs 19-22 C. Warmer in the southeast inland than most other regions. Rainfalls only 2-5 mm.

SUNDAY ... Partly cloudy, isolated showers, breezy at first (WNW 30-50 km/hr) then pleasant with light winds and some sunshine ... morning lows about 8-10 C and highs 20-23 C.

MONDAY-TUESDAY ... Partly cloudy, generally dry but some isolated showers possible mainly in Connacht and west Ulster, west to northwest breezes resuming at 30-50 km/hr and lows 6-9 C, highs around 19 to 21 C for most.

FURTHER OUTLOOK ... Warmer and at times very warm towards the end of the month. Some highs in the low to mid 20s likely by end of next week. Some low cloud near coasts but generally a very nice spell of sunny weather with light winds to end the month.


Forecasts for Britain

TODAY will become hot and humid in the southeast, then heavy showers and thunderstorms are likely by Friday night and Saturday morning. Highs 24-27 C in the south, 21-24 C central England and Wales, 18-21 C northern England and southern Scotland, 15-18 C northern Scotland where frequent showers are also likely.

FURTHER OUTLOOK will see quite similar weather to Ireland and the trend will be generally dry and near normal in temperature for several days through the weekend and early next week, then warmer in stages to near 30 C.


Forecasts for North America

Hot and humid weather will rapidly return north in the Great Lakes and Midwest and the southeast will continue to dry out, highs throughout should be near 30 C or a bit higher. A weak tropical system is drifting west in the Gulf of Mexico, but its main impact on land is to allow drying of the lower and mid-levels as winds shift to a more northerly direction. Texas remains quite hot and most of the west is sizzling under a sprawling ridge, highs are generally close to 40 C inland and near 28 C on the Pacific coast. A few weak thundershowers are drifting east through the Pacific northwest states and southern B.C. due to a weak and dissipating cold front.

My local weather on Thursday was sunny with increasing high cloud, highs near 26 C. There was virga but no rain around sunset.

Sunday, 25 August, 2013

Forecasts for Ireland


TODAY ... Partly to mostly cloudy at first with isolated showers, 2-5 mm rain in some parts of Connacht and west Ulster, but this activity will tend to fade away later with more sunshine developing ... breezy at times (WNW 30-50 km/hr) through the morning, then increasingly pleasant with lighter winds ... highs 17 north, 19 central, west and 20-23 C south, east.

TONIGHT ... Clearing skies, rather foggy or misty after midnight in some lower lying rural districts. Lows 6-9 C.

MONDAY ... Sunny with cloudy intervals, warm with afternoon highs 21-24 C for most, warmest in the south, but some parts of north around 17-18 C. Light northerly breezes may be more noticeable in Ulster and north Connacht where there could also be some longer cloudy intervals.

TUESDAY ... Increasing cloud, some light rain likely to spread across parts of the north and west, but some uncertainty about how far this will continue to advance before drying out, so that southeast could remain dry and even partly sunny. In any event rainfalls will be rather light, 2-5 mm potential north and west to trace amounts southeast. Lows 8-10 C and highs 18-21 C for most, 21-24 C possible in southeast if rain holds off.

WEDNESDAY to FRIDAY ... Hazy sunshine, warm or very warm, light and variable winds with sea breezes in various coastal regions, light winds inland ... lows 6-10 C and highs 21-26 C warmest inland south and west. This pleasant interval will gradually break down to scattered showers and gusty westerly winds although some sunshine will continue and some parts of the southeast could remain dry.

FURTHER OUTLOOK ... Somewhat greater chance of isolated showers on the weekend of 31 Aug-1 Sep although quite a bit of dry weather too and while some models are showing potential for cooler temperatures and gusty winds I am tending to a more moderate solution with highs about 20-22 C south and 16-18 C north, then likely returning to warm and dry 23-26 C in the first week of September under sprawling high pressure. Nights then should be clear with fog patches each morning.


Forecasts for Britain

TODAY will bring variable cloud, some afternoon sunshine more sustained in west and northwest, scattered showers in east mainly but tending to drift into south central England before dissipating by late afternoon, and highs 18 to 20 in the south and east, 17 to 19 west and north.

Most of next week will be warmer and drier except for some rain in Scotland and parts of northern England on Tuesday. Highs will be similar to Ireland in southern and central England, that is near 21 C at first to 25 C later in the week. It may be a few degrees cooler in parts of Scotland especially the west and north. A brief interruption is possible especially in Scotland around next weekend, gusty west to northwest winds and showers may develop but the conditions in southern England may only change slightly before warming back into the mid 20s in early September. The first of the autumnal overnight fog under otherwise clear skies could become a major detail, and this warm, dry settled interval could last several weeks once it resumes, with some highs of about 28-30 C possible in early September in southern England.


Forecasts for North America

The northeast U.S. and Ohio valley, lower Great Lakes will see an interval of very pleasant sunny weather with low humidity, comfortable overnight lows and warm days near 25 to 27 C. It will be hotter and more humid in the Midwest and central to northern plains states, highs 32-35 C. Some intense storms will develop in Minneosta moving towards the central Great Lakes. Hot and humid in Texas, and an outbreak of heavy monsoonal storms in northern Arizona and southern Nevada-Utah later today ... Las Vegas could see urban flooding with some cells capable of dropping 50 mm rain in the vicinity by afternoon. My local weather on Saturday was mostly cloudy with sunny breaks, and showers in the area although apart from some early morning drizzle we had no rain where I was.

Tuesday, 27 August, 2013

Forecasts for Ireland


TODAY ... Cloudy at first, scattered outbreaks of drizzle or light rain, but with a slight clearing trend mid-day as most of this drizzle moves further east with just patchy low cloud and coastal drizzle left over for parts of the northwest. Highs will average about 18 C but could push a little above 20 C anywhere that sees an hour or two of sunshine mid-day. Further rainfalls only trace to about 2 mm at most.

TONIGHT ... Cloudy with some clear intervals, mild, lows about 10-13 C.

WEDNESDAY ... Partly to mostly cloudy with afternoon sunshine developing, some patchy morning drizzle near south and west coasts, highs about 18-22 C.

THURSDAY ... Sunny with cloudy intervals, showers developing in west, slight risk of a brief thunderstorm in Connacht. Lows 9-12 C and highs 20-23 C.

FRIDAY ... Variable cloud, showers and a few thunderstorms more likely in north and around late morning to mid-day, breezy (WSW 40-70 km/hr in the north, 30-50 km/hr in the south) ... lows 9-12 C and highs 21-24 C.

SATURDAY ... Breezy, variable cloud north, sunny intervals south, with isolated showers, more frequent in Ulster and north Connacht where some could produce hail and thunder briefly, generally fresher in WNW winds 40-70 km/hr in the north, 30-50 km/hr south ... lows 8-11 C and highs 17-21 C.

SUNDAY ... Sunny with cloudy intervals, isolated showers, less breezy, morning lows about 5-8 C and afternoon highs 18-21 C. Light rain or drizzle may brush the northwest and north coastal regions by evening.

OUTLOOK ... Monday will probably be mostly cloudy with drizzle in parts of the north, hazy sunshine could break through in the south, then warmer air will push in for several days but the main question is whether cloud in this westerly air stream will break up enough to allow temperatures to reach the low or mid 20s, with 18-20 C possible if there's more cloud. Eventually this somewhat dull spell of weather could break to partly cloudy and fresher northwest winds briefly then another dry and somewhat sunnier spell is likely. The next week or two look rather dry except for isolated near normal amounts in the inland north.


Forecasts for Britain

TODAY will be overcast with some persistent mist or haze, and just a few sunny breaks, as light rain or drizzle edges further east into Wales and southwest England, highs near 21 C.

The outlook for Britain is generally about the same as yesterday, namely, dull and near normal temperatures most of this week, highs 21-23 C south and 18-20 C north, then cooler in stages with occasional light showers developing towards the weekend with a few heavier showers or brief thunderstorms Friday and Saturday in parts of western Scotland and northwest England, highs about 17-19 C. Fair and rather warm by Sunday and next week, mixture of sun and cloud, highs 22-24 C.

Forecasts for North America

Heavy showers and thunderstorms again in parts of the Great Lakes region, as very warm and humid air is confined mainly to central plains states and Midwest, somewhat cooler in New England and Quebec. More showery than recent days in Texas, slowly drying out over parts of the inland southwest that have seen locally heavy monsoonal rainfalls, but still a few thunderstorms scattered around with temperatures not quite as hot as usual (35-40 C instead of well into the 40s at lower elevations, and decidedly cool at higher elevations where record low daytime temperatures near 15 C have been observed on the higher plateaux. My local weather has been about the same as your own, dull with glimpses of sun and some drizzle at times, 18-20 C.

Thursday, 29 August, 2013

Forecasts for Ireland


TODAY ... Cloudy this morning with spotty drizzle followed by brighter skies and even a few some sunny intervals, isolated showers developing in west, slight risk of a brief thunderstorm in Connacht. Highs 20-23 C. Rainfalls only about 1-3 mm with some places staying dry. Rather light winds becoming SSW 20-40 km/hr at times.

TONIGHT ... Occasional showers, rather warm and humid with mist or fog patches, lows 12-15 C.

FRIDAY ... Variable cloud, showers and a few thunderstorms more likely in north around late morning to mid-day, breezy (WSW 40-70 km/hr in the north, 30-50 km/hr in the south) ... highs 21-24 C in south, 18-21 C north.

SATURDAY ... Breezy, variable cloud north, frequent sunny intervals south, with isolated showers more frequent in Ulster and north Connacht where some could produce hail and thunder briefly, generally fresher in WNW winds 30-50 km/hr ... lows 8-11 C and highs 17-21 C. Less breezy by afternoon and evening as a ridge of high pressure settles over the south.

SUNDAY ... Sunny with cloudy intervals, isolated showers possible but confined to a few parts of the north and west, rather calm in the morning with winds gradually increasing to SW 30-50 km/hr by afternoon ... morning lows about 5-8 C and afternoon highs 18-23 C. Light rain or drizzle may brush the northwest and north coastal regions by evening.

MONDAY ... Becoming mostly cloudy with drizzle in parts of the north, developing to showers and spreading across other regions by afternoon, some morning hazy sunshine could break through in the south, then some rain or showers followed by warmer air will push in late in the day. Highs 18-22 C.

TUESDAY to THURSDAY ... Mainly dry and fine mid-week with temperatures a little above normal in the low 20s, any chance of rain either across far north or arriving later Wednesday west into Thursday afternoon east. Turning cooler with fresh westerly winds on Thursday.

OUTLOOK ... Showery and cooler towards end of the week but another dry spell to follow with temperatures near or slightly above normal 7-15 Sept.


Forecasts for Britain

TODAY will be overcast with light showers, highs 20-23 C for most but around 17-19 C in Scotland and higher parts of northern England,

The outlook for Britain is fair and rather warm on Thursday and early Friday followed by gusty winds, showers and a cooler, fresher weekend. Highs will average 23-25 C tomorrow and Friday, and 18-21 C on the weekend in most regions, although quite windy at times in Scotland with heavier showers there. The following week will be similar to Ireland as per the above outlook. Temperatures will remain a bit above normal except near normal on Thursday and Friday. Rainfall will be somewhat below average for the period.


Forecasts for North America

Some of the hottest weather of this summer continues in the central states and parts of the Midwest, Ohio valley with highs 34-38 C. The northeast, mid-Atlantic states and Great Lakes region are mostly a bit cooler now as a weak frontal boundary has pushed south, bringing highs of about 24-27 C. Severe storms are moving across the Dakotas towards northern Minnesota and parts of Manitoba and northwest Ontario. Further west, it's cloudy with a few showers and normal late August temperatures in the 20s. Texas and parts of the southwest have returned to a hot, dry pattern. My local weather on Wednesday was cloudy with outbreaks of light rain and highs of about 20 C.

Saturday, 31 August, 2013

Forecasts for Ireland

TODAY … Breezy, variable cloud north and west, partly cloudy but frequent afternoon sunny intervals south and east, with isolated showers more frequent in Ulster and north Connacht where some could produce hail and thunder briefly, generally fresher in WNW winds 30-50 km/hr … highs 16-19 C. Less breezy by afternoon and evening as a ridge of high pressure settles over the south, showers then dying out over the north.

TONIGHT ... Clear intervals, cool with lows 6-10 C, coolest inland south and east.

SUNDAY … Sunny with cloudy intervals, isolated showers possible but confined to a few parts of the north and west, rather calm in the morning with winds gradually increasing to SW 30-50 km/hr by afternoon … morning lows about 5-8 C and afternoon highs 18-23 C. Light rain or drizzle may brush the northwest and north coastal regions by evening.

MONDAY … Becoming mostly cloudy with drizzle in parts of the north, developing to showers and spreading across north-central regions by afternoon or evening, morning hazy sunshine should persist in the south, then overcast by afternoon except near the southeast coast where sunshine could continue longer, and likely staying dry in the south. Highs 18-23 C warmer in the south.

TUESDAY ... Overcast with light rain or drizzle at times in the northwest, trending to partly cloudy and warm in the southeast, highs 17-23 C warmest in the southeast.

WEDNESDAY ... Showers and risk of a thunderstorm, turning somewhat cooler in the west and north, highs 16-21 C.

OUTLOOK ... Most of the guidance signals a cooler interval on Thursday and Friday with warmer weather returning over the weekend of the 7th-8th and very warm in the following week. The latest European model guidance adds the rather different scenario of the flow rapidly changing to easterly late in the week with a rapid infusion of warmer air from the east, whereas some of the other models have continued westerly flow that swings more to northerly for a few cooler days then back to southwesterly for the warming trend. With this uncertainty, we can only stress the general theme of a cooler end to the week and warming beyond that. The details remain uncertain.

SEASONAL OUTLOOK for autumn 2013 is generally warmer than average and relatively dry, with chance of a cooler interval late September and early October. Otherwise, expect near normal or slightly above much of the time, and perhaps well above normal at times in November.


Forecasts for Britain

TODAY will be sunny with cloudy intervals, and isolated showers or thunderstorms developing mainly to the west and north of the Midlands. Highs will range from 22 C in the southeast to 17 C in northern England and most of Scotland where it will be quite breezy (W 50-70 km/hr at times). A few of the northern showers could contain hail and thunder.

OUTLOOK is generally dry and near normal in temperatures for several days, with some patchy dense fog at night in rural southern England. The outlook from mid-week on is similar to Ireland with the same set of uncertainties about the circulation pattern, with some chance of much warmer air from the continent reaching parts of southeast England while other regions turn a bit cooler at the end of the week.


Forecasts for North America

The heat continues in parts of the Midwest, central plains and Ohio valley with more frequent thunderstorms today. Highs will reach the low 30s. Showers and thunderstorms becoming frequent in the northeast states, highs 25-28 C. Warm and dry across large portions of the western U.S. but unsettled with widespread showers and a few thunderstorms near the Canadian border and into western Canada. My local weather on Friday was overcast with a few sunny breaks, following an overnight heavy thunderstorm that started fires with lightning strikes around the greater Vancouver region. This was one of the two or three most intense thunderstorms I've seen here in almost twenty years although rather typical of storms inland and further east.

Monday, 2 September, 2013

Forecasts for Ireland

TODAY … Mostly cloudy with drizzle in parts of the north, developing to a few spotty showers and spreading across some north-central regions by afternoon or evening, rainfalls only 1-3 mm at most, and confined to Ulster, north Leinster and north Connacht, meanwhile morning hazy sunshine through extensive high cloud should persist in the south, becoming partly cloudy to overcast by afternoon except near the southeast coast where sunshine could continue longer, and likely staying dry in the south. Highs 18-23 C warmer in the south. The morning may be rather windy in the north (WSW 30-50 km/hr) but less so near the south coast and parts of Leinster.

TONIGHT ... Less windy in the north with the cloud breaking to some extent except near outer headlands, where some drizzle may continue, clear intervals most other regions, lows about 8 to 11 C, coolest inland south.

TUESDAY ... Overcast with light rain or drizzle at times in the northwest, trending to partly cloudy and warm in the southeast, lows 7-10 C and highs 17-23 C warmest in the southeast and east.

WEDNESDAY ... Showers or periods of rain, 10-15 mm on average, turning somewhat cooler in the west and north, continuing fair and warm in parts of the south and east, at least until mid-day or afternoon, with lows 7-12 C and highs 16-22 C.

THURSDAY ... Morning showers followed by variable cloud and cooler in northerly breezes. Lows 10-13 C and highs 13-16 C.

FRIDAY ... Partly cloudy with isolated showers, lows 4-8 C and highs 14-17 C.

OUTLOOK ... It seems fairly certain that winds will back to easterly and somewhat warmer air will return eventually but there could be a rather cloudy and wet interval around the weekend with highs 14-17 C as low pressure forms in the vicinity of southwest England during the weekend. This may spread rain or drizzle across some parts of the south and east but may leave the north and west dry if rather cloudy. Warmer and drier conditions will follow as this low loses its circulation and is forced out by swelling high pressure to the northwest ridging through to Scandinavia. Eventually it could be as warm as the low to mid 20s by middle or end of next week as this pattern allows for sunshine and light east winds.


Forecasts for Britain

TODAY will be partly cloudy with some rather dense higher cloud obscuring the sun and possibly one or two brief showers developing, but on the whole it should become dry and even sunny in most of the south, more cloudy but dry in central regions and overcast with one or two showers in the north. Highs will range from 23 C in the inland south, to 16 C in parts of western Scotland, where it will also be quite breezy (SW 40-60 km/hr), and around 19-22 C in much of Wales and central to northern England with moderate westerly breezes.

OUTLOOK is generally dry and near normal in temperatures for several days, with some patchy dense fog at night in rural southern England. Highs Tuesday to Thursday in the south will average 23-25 C. Rain will slowly overspread southern parts of Britain on Thursday after gathering over northern and central regions late Wednesday, and then it will turn considerably cooler for two or three days with highs around 16 C. Showers will develop during the weekend over parts of southwest England and Wales, but it may remain dry if cloudy further east and north, then drier and sunny conditions will spread in from the north early next week with a gradual warming trend back into the 20s.


Forecasts for North America

More showers and thunderstorms will develop today (Labor Day in the U.S. but Labour Day in Canada) in many parts of the east while a slightly cooler but continuing warm and humid air mass drops south into the Midwest with highs near 27 C. It will remain quite hot further south and west, with outbreaks of showers and thunderstorms over many parts of the western mountains and plateaux, but dry and sunny near the west coast. My local weather on Sunday was sunny and very warm with highs near 26 C.

Wednesday, 4 September, 2013

Forecasts for Ireland

TODAY … Showers or periods of rain will edge slowly east from the Atlantic coast, eventually bringing 10-15 mm rain on average, with the afternoon turning somewhat cooler in the west and north, but continuing fair and warm in parts of the south and east, with perhaps more cloud than sun in most places, but quite warm until the rain arrives, with highs 16-22 C, warmest in Leinster and east Munster.

TONIGHT ... Rain becoming rather light and drizzly before ending, and some locations around Wexford could remain dry, winds shifting to northwesterly and lows around 10 C to 13 C in the southeast.

THURSDAY ... Morning showers followed by variable cloud and cooler in northerly breezes 25-45 km/hr, highs 13-16 C.

FRIDAY ... Partly cloudy with isolated showers, quite cool to start with lows only 3-7 C in most inland locations, and highs 14-17 C. Winds rather variable but trending towards the northeast.

SATURDAY ... Periods of rain (10-20 mm) in most regions (confidence in this has grown to about 70% now) and rather cool with northeast winds backing to southeast by the overnight hours. Temperatures steady 10-13 C but could reach 16 C if the skies are not continuously overcast in some places.

SUNDAY ... Variable cloudiness, showers with brief sunny intervals, and highs 16-18 C.

OUTLOOK ... There could be further bouts of showery rainfalls as this disturbance becomes trapped under a ridge of high pressure to the north, or drifts further north and splits into several centres, yet at the same time, situations like this often turn out more variable with some decent spells of weather embedded in the circulation as well as the showery portions. Eventually there will likely be some fair and warmer conditions for part of the mid-week but signals are generally not very strong.


Forecasts for Britain

TODAY will be sunny with cloudy intervals and very warm with highs 24-27 C in the inland south and central regions, 18-22 C further north. Showers will move into parts of western Scotland by afternoon or evening.

TONIGHT will see showery outbreaks of rain in parts of the north-central regions but it will stay partly cloudy and very mild further south, rain arriving by morning in the southwest and parts of Wales, west Midlands. Lows about 14 to 17 C.

OUTLOOK is for wet weather to become more frequent as rain moves north from France towards Friday and the weekend, some heavy falls could develop. This weather pattern will slowly break down to variable cloudiness and just showers here and there with near normal temperatures.

Forecasts for North America

It will remain fair and very warm across large sections of the U.S. and southern Canada with much cooler air moving southeast into the upper Great Lakes preceded by showers. This fall-like air mass is headed more for New England than the rest of the northeast or Midwest. Showers are scattered across most of the higher elevations of the west. My local weather on Tuesday was overcast with periods of rain and fog, clearing late afternoon, with highs near 19 C.

Friday, 6 September, 2013

Forecasts for Ireland

ALERT for heavy rains in north Leinster and east Ulster tonight and Saturday morning, amounts of 20-30 mm in total with moderately strong northeast winds 40-60 km/hr. It will also be wet and windy elsewhere but amounts of rain will be closer to 15-20 mm. This inclement weather will feel much colder than recent days.

TODAY … Partly cloudy with isolated showers, heavier in west Munster this morning (5-8 mm locally there), and quite cool to start (Mountdillon was reporting 1 deg C before dawn) with morning temperatures slow to reach 10-12 C in most inland locations, and eventual highs of 14-17 C. Winds rather variable but trending towards the north then northeast at 20-40 km/hr. Some locally heavy showers are likely in parts of Leinster by late afternoon.

TONIGHT ... Rain will become heavy at times (10-20 mm) in north Leinster and east Ulster with winds near the coast NE 40-60 km/hr, elsewhere just drizzle or cloudy skies and winds 25-45 km/hr. Lows 7-9 C.

SATURDAY ... Periods of rain (15-30 mm) in most regions and continuing rather cold with northeast winds 30-50 km/hr adding chill in some parts of Ulster and Connacht, north Leinster, but these winds should ease around mid-day while picking up from the west to northwest across the south and west due to the movement north of low pressure. Temperatures steady 10-13 C but could reach 16 C if the skies are not continuously overcast in some places -- this would be more likely in west Munster or parts of the inland southeast.

SUNDAY ... Variable cloudiness, showers with brief sunny intervals, and highs 14-17 C. Rain is more likely to be heavy near north and south coasts, and amounts may range from 10-15 mm in these bands, to 3-5 mm elsewhere.

MONDAY ... Cloudy with a few sunny breaks, further showers, temperatures recovering slightly to highs of 15-18 C.

OUTLOOK ... There will be a gradual drying and warming trend as higher pressure to the west begins to move closer, but the north could see further rainfalls at times. Highs by middle of next week could be closer to 20-22 C, and further warming is possible beyond that, as some models are showing a gradual swelling up of high pressure around 12th to 15th while low pressure that contains remnants of slow-moving Gabrielle drifts north towards Greenland in the west-central Atlantic. So summer may not be quite done yet although this weekend is likely to feel more like late October.


Forecasts for Britain

TODAY and SATURDAY will be generally wet days especially in southern England where 20-40 mm could fall, in variable cyclonic winds (easterly north of about Cambridge to B'ham to central Wales, northwesterly in Cornwall and Devon). Highs will be about 14-17 C and temperatures will only fall a degree or two at night. Heavy rain will tend to move further northwest late tonight and Saturday with more showery conditions to follow across the south. The stronger east winds will move north across Scotland by later Saturday and moderate southwest winds will then replace them across the south and central regions.

OUTLOOK is for this weather pattern will slowly break down to variable cloudiness and just showers here and there with near normal temperatures.


Forecasts for North America

Most regions continue to bask in very pleasant sunny weather with highs generally in the high 20s to low 30s. It's somewhat cooler still in New England and Quebec, and even warmer across the south central to southwest states. Heavy showers and thunderstorms continue in parts of the northwest states and British Columbia. My local weather on Thursday was cloudy with showers and evening thunderstorms (some locally severe in terms of frequent lightning) and highs were about 20 C.

Please note: I will try to update the forecast Monday morning at the usual time but I am going to be away from home base for a few weeks and I'm not sure what access I might find to the internet. So if there's no forecast, watch for a later update instead.
