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.

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.

TODAY … Variable cloudiness, showers or periods of light rain and drizzle, with brief sunny intervals, the rainfall becoming more banded through the day, and highs 14-17 C. Further amounts may range from 10-15 mm in these bands, to 3-5 mm elsewhere, and sunshine of 2 to 6 hours can be expected.

TONIGHT ... Mainly cloudy, light showers, lows 5-8 C.

MONDAY ... Cloudy with a few sunny breaks, further showers, temperatures recovering slightly to highs of 15-18 C after morning lows 5-8 C.

TUESDAY-WEDNESDAY ... Continued rather cloudy and somewhat unsettled although showers more prevalent in north, lows 5-8 C and highs 16-19 C.

OUTLOOK ... Rather extensive and heavy showers Thursday followed by breezy weather and somewhat cooler again, highs near 20 C Thursday, 16-18 C Friday to Sunday. The week beyond next weekend could turn out quite warm.


Forecasts for Britain

TODAY ... Variable cloud, showers and one or two brief thunderstorms, humid but not overly warm with highs 16-19 C.

OUTLOOK ... Very similar trends to Ireland can then be expected.


Forecasts for North America

Warm and dry in many parts of the eastern and central U.S., but heavy showers and thunderstorms in the Dakotas, Minnesota. Rather cloudy across most of the Gulf coast, and parts of the far west. Outbreaks of rain fairly common across western Canada. My local weather on Saturday was cloudy to start, sunny and very warm by afternoon, highs near 25 C.

Tuesday, 10 September, 2013

Forecasts for Ireland

TODAY ... Intervals of cloud and sunshine, isolated showers most likely near north coast. Highs 17-20 C.

TONIGHT ... Clear intervals, some mist or fog patches. Lows 6-9 C.

WEDNESDAY ... Sunny intervals with increasing afternoon cloud, periods of light rain later or by evening (overnight southeast). Highs about 18 to 21 C.

THURSDAY ... Hazy, rather warm, further showers possible. Lows 7-10 C and highs 18-21 C.

OUTLOOK ... Breezy, not quite as warm with strong gusts at times in north around Sunday-Monday (westerly 60-80 km/hr). Highs generally about 17 C south to 14 C north. Some risk of showers north and west but frequently dry.

Forecasts for Britain

TODAY will be mostly cloudy with intervals of rain in the east and southeast, highs there about 15 C, trending somewhat warmer in west and north-central although 18 C about the top reading, rather breezy from north with the eastern showers.

OUTLOOK will then become more similar to Ireland as this mid-week disturbance fades out.

Forecasts for North America

I have relocated for three weeks to Ottawa in eastern Canada where I'm likely to see some heavy thunderstorms at times today, part of a frontal wave moving east through the central Great Lakes. Further south, it's hazy and very warm with highs near 30 C. Large parts of the central U.S. will be dry and warm to hot again today, more showers further west.

Thursday, 12 September, 2013

Forecasts for Ireland

TODAY ... Hazy or cloudy with limited sunny breaks, rather warm, further showers possibly becoming steady rain by afternoon or evening with highs 18-21 C. Further rainfalls of 3-5 mm.

TONIGHT ... Cloudy, rain continuing in south, mild with lows 11-14 C.

FRIDAY ... Partly cloudy in most regions, some lingering rain south coast, breezy to windy and not quite as warm, isolated showers, winds increasing later to 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 at least on Saturday as highs edge back towards 20 C in a moderate W-SW flow. Sunday could be closer to 17-18 C and winds will rapidly increase from a westerly direction with rain spreading into the north, showers further south. Monday then looks quite blustery and a bit cooler.

Forecasts for Britain

TODAY will cloud and a few showers developing with brief sunny intervals, rather warm with highs 17-21 C.

The outlook is broadly similar to Ireland beyond that.


Forecasts for North America

Heavy storms will sweep through the northeast ending a brief heat wave that saw highs reach 35 C in places on Wednesday, then a secondary cold front will terminate all warmth in the east later today or tonight, creating a second band of weaker thundershowers (I saw distant lightning twice in Ottawa and could see more storm action this afternoon). The western half of the continent is baking under brilliant sunshine and highs into the 30s (40s southwest U.S.) and any cooler air is wedged in between over Manitoba, northern Ontario and this will spread south but modify rather quickly to give a fine weekend in most places as eastern and western highs join coast to coast. Eastern Canada will see the remnant low of Gabrielle and locally heavy rain later today.

Saturday, 14 September, 2013

Forecasts for Ireland

TODAY ... Partly cloudy (some nice sunny intervals for parts of the morning and mid-day) to overcast by afternoon with showers developing, winds rather light and variable at first, increasing later in day to SW 40-60 km/hr. Highs near 15 or 16 C in the north to 18 or 19 C south and east.

TONIGHT ... Windy with showers or periods of rain heavier in north and west where 5-10 mm likely, winds WSW 40-60 km/hr and lows 8-10 C.

SUNDAY ... Breezy to windy with highs of 16-18 C as winds will rapidly increase from a westerly direction (50-70 km/hr) with rain spreading across all regions during the morning, blustery showers at times with chance of hail mainly in Connacht and west Ulster. Gusts to 90 km/hr possible near northwest coast. Sunday night will likely continue very blustery with winds slowly veering more to WNW 50-70 km/hr, low of about 9 C.

MONDAY ... Blustery with squally showers at times, some sunshine too, highs near 16 C in sheltered parts of south, otherwise 13-14 C.

OUTLOOK ... Models are backing off any sustained improvements with smaller disturbances coming along behind this Sunday-Monday large-scale wind/rain event, so expect further showers and rather cool temperatures in general most of the week. Further down the road, Humberto could attempt to make a run towards the northeast from west of the Azores later next week but most guidance shows this system being eliminated before it reaches Ireland -- if it does become a factor, it would most likely be around 8-10 days from now.

Forecasts for Britain

TODAY will feature some improvement as a weak ridge develops and some sunshine breaks through widespread cloud, highs 17-19 C. Squally showers will reach western Scotland before evening and then spread rapidly further south. TONIGHT will become windy and showery anywhere north of Bristol to Norfolk. SUNDAY and MONDAY will have windy and showery conditions with highs near 18 C south to 14 C north. The OUTLOOK is similar to Ireland generally although some better spells could develop in the southeast.

North American forecasts

Hot and dry in many parts of the west with continuing rainfalls in some parts of the southern Rockies. Cool and sunny in the Midwest and northeast U.S., cloudy further south with occasional light rain, highs only 16-20 C. In Ottawa today it was cloudy and (bl**dy) cold with a stiff northerly wind and 10-12 C temperatures. That compares to 30 C on Wednesday afternoon! :eek::D

Monday, 16 September, 2013

Forecasts for Ireland


TODAY ... Very windy especially near north and west coasts, and other well-exposed locations. Winds from WNW at 60-100 km/hr at times. Squally showers, one or two with hail and thunder, with rainfalls of about 5-10 mm on average. Best chance of any sunshine near south coast and parts of Wicklow. Highs only 12-15 C.

TONIGHT ... Winds not as strong, cloudy with outbreaks of light rain especially after midnight in west and south. Lows 7-9 C.

TUESDAY ... Intervals of rain, low cloud or fog in parts of north and east, highs 14-17 C warmest in south and west Munster. Rainfalls 15-25 mm.

WEDNESDAY ... Becoming partly cloudy to sunny at times, showers more isolated if any, lows 3-6 C and highs 14-17 C.

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.

Forecasts for Britain

Similar to above, Monday especially windy in Scotland, Tuesday particularly wet in southwest England.

Forecasts for North America

Rain moving east through the inland northeast U.S. and lower Great Lakes will be followed by a renewed push south of cool high pressure clearing skies later on in some areas, highs only 13-16 C. Warmer to south although average September highs in 20s. Very warm further west, 30-35 C into Alberta and Montana. Rain closer to the west coast and Hurricane Ingrid moving inland on east coast of Mexico late today or tonight.

Presently in Ottawa I have rain and 12 C after a cloudy day with high 17 C.

Wednesday, 18 September, 2013

Forecasts for Ireland


TODAY ... Becoming partly cloudy to sunny at times, showers more isolated and tending to die out over south, possibly redeveloping later for parts of the north. Highs 14-17 C. Moderate westerly breezes at times.

TONIGHT ... Increasing cloud, rain for northern counties, showers or mist further south. Lows 7-10 C.

THURSDAY ... Rain could be heavy at times in Ulster and nearby parts of Connacht and north Leinster, 10-15 mm by mid-day then somewhat clearer skies already present in parts of west and south should gradually replace the rain with highs 12-15 C north and 15-18 C south.

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 ... Another 2013 warm spell !! This may not prove to be the best summer / early autumn ever, but it has provided its share of fine weather and another pleasant spell is foreseen for part if not all of next week. Highs could reach the lower 20s inland. Extensive fog and coastal low cloud may accompany this spell due to light or even calm winds under high pressure.


Forecasts for Britain

TODAY will be partly cloudy to overcast with isolated showers, highs 14-17 C.

The extended forecast is generally very similar to the Ireland forecast and much warmer weather will spread in next week. Rain moving through on Thursday into early Friday will likely be heaviest in north Wales and north-central England.


Forecasts for North America

The fine spell of clear weather continues for today in parts of the northeast U.S. and eastern Great Lakes. Cloud continues to spread in slowly from the west across the Ohio valley and central to western Great Lakes. Highs in most of these regions are seasonable near 22-24 C. Rain has spread east from the Rockies overnight and today will be quite wet and much cooler than recent days in Alberta and western Montana, with the risk of severe storms in a few parts of Saskatchewan, western Manitoba and the Dakotas. Further south it remains warm and dry. The west coast is now seeing some clearing.

In Ottawa on Tuesday it was perfectly clear and sunny with a pleasant high of about 20 C. The overnight is also clear with an almost full moon and it's quite chilly at about 7 C.
