UPDATE __ Wed 26 July 2017 __ 6 p.m.
__________________________________________

ALERT for heavy thunderstorms and brief torrential downpours with a squall line feature now entering north-central Leinster, likely to race eastward to the Irish Sea coast by 8 p.m., and affecting most if not all counties in Leinster (Wexford may not be included), east Ulster (south of Lough Neagh-Belfast), and whatever portions of Connacht remain ahead of this feature (effects already noted further west).

Expect to find flooded portions of roads if you are heading northwest out of Dublin, if this happens to miss the capital region, or affecting mainly north Dublin and Kildare, which seems possible although not guaranteed. The worst of this storm seems likely to head across Longford, Offaly, Westmeath, Cavan, Louth and Meath. It is fast moving, 10-20 mm of rain can fall in less than an hour, some lightning has been reported and small hail is possible. Wind gusts to at least 80 km/hr are likely. Very small risk of an isolated F-1 tornado in this set-up (again most likely to be in rural areas well north or northwest of Dublin).

Temperatures fall sharply with this front, currently only 12 to 13 degrees over much of Connacht.

Forecasts for Ireland


TODAY ... Intervals of cloud and sunshine, passing showers still rather widespread during the day, with slight chance of a thunderstorm, highs 17 to 19 C. Not quite as windy as Thursday but some moderate southwest gusts at times (40 to 70 km/hr). An area of moderate rainfall will brush the south coast mid-day but most of that should be over the ocean.

TONIGHT ... Mostly cloudy, occasional light rain, lows 8 to 11 C.

SATURDAY ... Partly cloudy, a few showers and a further reduction in the winds, to southwest 30 to 50 km/hr, morning lows near 8 C and afternoon highs near 19 C.

SUNDAY ... Partly cloudy, cool with occasional showers, breezy at times (westerly 40 to 70 km/hr), lows near 8 C and highs 16 to 18 C.

MONDAY ... Mostly cloudy, a few intervals of light rain, cool, highs near 17 C.

TUESDAY ... A few sunny intervals to start, lows near 7 C and highs near 21 C, then windy with rain by late in the day, strong southerly winds developing overnight into Wednesday morning (50 to 80 km/hr).

OUTLOOK ... The strong low discussed in yesterday's outlook is still there on most guidance charts and passes to the west of Ireland by Wednesday, lingering around to the north on Thursday and slowly crossing Britain on Friday. The heaviest rain is well out ahead of the system (in the late Tuesday and early Wednesday forecast above), but more showers will follow from Wednesday afternoon to about Saturday the 5th of August. Beyond that, the charts are not showing much sign of improvement but this will depend on the actual track taken by the low during next week.

My local weather on Thursday was mostly cloudy in the morning then sunny by afternoon with a somewhat cooler high of 23 C.

Sunday, 30 July, 2017

Forecasts for Ireland


TODAY ... Widespread showers and a few thunderstorms, 5 to 10 mm amounts on average, 15 to 20 mm potential in a few spots. There may be a break between one band this morning and a second one due to arrive mid-day to early afternoon on the west coast, so some brief sunny breaks are possible especially over the southeast. Highs 17 to 20 C.

TONIGHT ... Frequent showers or light rain, about 5 mm, lows near 12 C.

MONDAY ... Intervals of cloud and sunshine with showers and a few thunderstorms, highs near 19 C.

TUESDAY ... Some sunny intervals in south and east, mostly overcast in west and north, with some rain at times near coasts. Light winds at first, increasing to southeast 40 to 70 km/hr at least for Munster and Connacht, south Leinster, where heavier rain may develop by evening. Morning lows 6 to 9 C and afternoon highs about 18 to 20 C.

WEDNESDAY ... Warm and humid, winds veering from southeast 40-70 km/hr to south-southwest 40-60 km/hr, heavy showers and possible thunderstorms with some partial clearing by afternoon, morning lows near 12 C and afternoon highs 19 to 21 C.

THURSDAY ... Partly cloudy, showers, rather breezy at times, lows near 10 C and highs near 18 C.

OUTLOOK ... Friday to Monday (4th to 7th August) looks rather cool and unsettled with a west to northwest flow, moderate breezes, and highs 16 to 19 C.

FURTHER OUTLOOK ... There could be a brief break in the action around Tuesday the 8th then back to an Atlantic regime with frequent showers.

My local weather on Saturday was sunny with a fresh sea breeze and highs near 22, much warmer further inland. It has turned rather cool for late July in the eastern states, with highs in the mid-20s and heavy rainfalls around Washington D.C. in the past two days (about 100 mm in places).

Tuesday, 1 August, 2017

Forecasts for Ireland


TODAY ... A mixture of cloud and sunshine for most, as shower activity retreats north into Ulster. There could be some isolated showers elsewhere, but many will enjoy a brief break from the rain with highs of 18 to 20 C.

TONIGHT ... Overcast, rain becoming heavy at times (10-15 mm), but moving quickly northeast followed by partial clearing in the west. Mild with lows 11 to 14 C. Winds becoming moderate southeast 40 to 70 km/hr, then southerly 30 to 50 km/hr by morning.

WEDNESDAY ... Rather warm and humid with the heavier rain ending by mid-morning in Leinster and Ulster, followed by some clearing but further showers and isolated thunderstorms. Highs 18 to 22 C.

THURSDAY ... Breezy to windy at times, partly cloudy with a few showers, cooler, morning lows 8 to 10 C and afternoon highs 16 to 19 C.

FRIDAY ... Variable cloud, isolated showers, more sunshine near south and east coasts, lows 7 to 10 C and highs 16 to 19 C.

SATURDAY ... Partly cloudy, a few showers, lows near 8 C and highs 18 to 20 C.

SUNDAY and MONDAY ... Frequent showers or periods of rain, rather cool. Lows near 10 C and highs 15 to 17 C.

OUTLOOK ... Warmer for a day or two Tuesday 8th-Wednesday 9th, highs 21 to 23 then becoming unsettled again with highs 18 to 20 C.

My local weather on Monday was sunny and hot with highs near 30 C. Scorching heat is developing over the western U.S. states and Canadian provinces, with highs reaching the mid-30s even near the coast, to near 40 C inland. The fire situation has been somewhat under control but this won't be very helpful. Meanwhile, unexpected Tropical Storm Emily formed rapidly west of Florida, moved across the state in a weakening condition, and may redevelop over the open Atlantic heading northwest of Bermuda. Any remnants of that would likely have lost tropical characteristics several days before reaching Ireland perhaps by next week.

Thursday, 3 August, 2017

Forecasts for Ireland


TODAY ... Just a few light showers left over now, and these should dissipate soon before some sunny intervals develop mid-day. A few more scattered showers are possible by afternoon and evening but in general, amounts only 1-3 mm and some places could have a dry day. Moderate west to northwest winds 40-60 km/hr at times, with rather cool highs of 16 to 18 C.

TONIGHT ... Some clear intervals, cool with lows 5 to 9 C for most, around 10 C in some coastal and urban locations. Still a slight risk of showers near Atlantic coasts.

FRIDAY ... Variable cloud, isolated showers, more sunshine near south and east coasts, moderate northwest winds, and cool with highs 16 to 19 C.

SATURDAY ... Partly cloudy, a few showers, lows near 8 C and highs 18 to 20 C.

SUNDAY and MONDAY ... Frequent showers or periods of rain, rather cool. Lows near 10 C and highs 15 to 17 C.

OUTLOOK ... Warmer for a day or two Tuesday 8th-Wednesday 9th, highs 21 to 25 then becoming more unsettled again with highs 18 to 21 C. The latest guidance backs off a little on how unsettled it becomes and there is some hope of further dry spells developing by the weekend of 12th-13th, with highs around 22 C. The overall look of the next two weeks on the weather charts is quite average for early to mid- August.

My local weather on Wednesday was a bit like Dante's inferno, hot and smoky, with highs reaching 32 C locally and 37 C further inland. Some parts of the Pacific northwest states were a little over 40 C. There are now fires burning in central B.C., southern Alberta, western Montana and central Idaho, and a lot of smoke from all of these is drifting in a westward direction now as a large-scale heat trough has developed over the inland west. That leaves central and eastern North America in a relatively cool pattern with some heavy rainfalls in the Dakotas and Minnesota on Wednesday. The pattern is rather static although we do expect a slight decrease in the heat next week.

Excitement is mounting as we prepare to go chase the total solar eclipse in Oregon or Idaho (possibly Wyoming) on August 21st, by "chase" I mean select an optimal spot based on weather guidance the day before, already being somewhere near the track. So I will be away from this desk for about ten days starting on the 15th.

Saturday, 5 August, 2017

Forecasts for Ireland


TODAY ... Partly cloudy, scattered showers with isolated thunderstorms, more widespread in Ulster and north Connacht where 10-15 mm rainfalls could occur, more of a hit-or-miss 2 to 5 mm further south. Highs 16 to 19 C.

TONIGHT ... Rain developing (10-15 mm) with fog and lows near 12 C.

SUNDAY ... Rain becoming more confined to Leinster and east Ulster during the morning, as partly cloudy conditions develop further west, and eventually some clearing further east. A few more showers are likely after the clearance mainly across northern counties. Cool, with highs only 15 to 17 C.

MONDAY ... Occasional showers, some sunny breaks, and continued rather cool with lows 6 to 9 C and highs 16 to 19 C.

TUESDAY ... Very cool with a few showers, some breaks in the overcast, and northwesterly breezes, lows 5 to 8 C and highs 14 to 17 C.

WEDNESDAY ... Some hazy sunshine at times, warmer, highs 18 to 22 C.

THURSDAY ... Increasing cloud, some rain by afternoon and evening (heavier north) and continuing warmer with highs around 21 C.

OUTLOOK ... Rather unsettled but fairly warm by end of the week and into the following weekend, highs 20 to 23 C. Beyond that, although confidence is low, the guidance suggests a continued unsettled pattern.

My local weather on Friday turned out rather cloudy from a combination of smoke haze and marine cloud, it was warm and humid although a sea breeze kept it from reaching 30 C in most places, closer to 24 C at my location. Near-record heat continues inland (although I notice that it was 5 degrees warmer in 1961 than today's highs, must have been a scorching spell then, for example 44 C in southeast WA state in 1961, about 39 today).

Monday, 7 August, 2017

Forecasts for Ireland


TODAY ... Continued rather cool and unsettled with passing showers, becoming somewhat more frequent by mid-day. Highs only 14 to 16 C north, 16 to 18 C south.

TONIGHT ... Showers gradually ending, some clear intervals developing although considerable low cloud will linger in a northwest flow, lows 8 to 11 C.

TUESDAY ... Cloudy with some sunny intervals, occasional showers developing and one or two thunderstorms in the central and northern inland counties. Moderate north-northwest winds 40-60 km/hr, highs only 14 to 17 C.

WEDNESDAY ... Sunny with cloudy intervals, most places dry, and becoming warmer by afternoon. Morning lows 5 to 9 C, afternoon highs 18 to 20 C.

THURSDAY ... Hazy sunshine with increasing cloud by late in the day, warm. Lows about 10 C and highs about 20 to 23 C. Rain may brush northwest coastal districts by evening and overnight, with this rain fragmenting to showers as it moves a bit further south by Friday early morning.

FRIDAY ... A few showers, then partial clearing, continued rather warm, highs about 20 to 23 C.

OUTLOOK ... The warmer spell may persist with just slightly unsettled intervals during the weekend, but certainly improved over this past few days, as highs continue to register in the low 20s inland. Eventually a more breezy, autumnal westerly regime will arrive and drop temperatures back into the 15 to 18 C range, around the third week of August.

My local weather on Sunday continued rather hazy although some of the smoke we have been enduring has drifted back to the southeast, so that the sun was shining almost at normal strength. Highs reached about 25 C.

Wednesday, 9 August, 2017

Forecasts for Ireland


TODAY ... Sunny intervals in most regions, somewhat more cloud in the northwest where isolated showers are possible. One or two showers could also develop by afternoon near the Wicklow coast but these may remain over the Irish Sea, drifting south. Winds northerly 20-40 km/hr. Highs 17 to 20 C, warmest near south coast.

TONIGHT ... Clear intervals, cool, lows 7 to 10 C. Somewhat more cloud near north coast, lows 10 to 12 C. Light winds.

THURSDAY ... Hazy sunshine for the south and central counties, increasing cloud across the north, rather warm, highs 17 to 22 C, warmest east coast, midlands, inland south. Moderate southwest winds developing by afternoon.

FRIDAY ... Early morning rain in the north will tend to fragment to showers as it tries to push further south by late morning, and the south could remain dry all day. Cloud will be prevalent but some sunny breaks could develop across the south by afternoon. Lows 11 to 14 C and highs 18 to 22 C in moderate southwest winds.

SATURDAY ... Sunny intervals, morning lows 8 to 10 C and afternoon highs about 18 to 20 C.

SUNDAY ... Some sunshine in north and east, increasing cloud for south and west, rain arriving by evening in Munster. Morning lows 5 to 9 C, afternoon highs 16 to 19 C. In light southeast winds, the warmest part of the country is likely to be inland north, midlands.

MONDAY ... Some rain at times, then partial clearing, highs near 17 C.

OUTLOOK ... Breezy to windy most days next week (typically WSW 40-60 km/hr), temperatures generally near or slightly below normal (highs 16 to 19 C) and near average amounts of rain.

My local weather continued quite hazy and warm on Tuesday, with highs about 26 C. We are expecting a gradual freshening of this stagnant smoky air mass from end of the week through early next week as the extensive heat trough over western North America weakens, but then it may return later in August at times.

Friday, 11 August, 2017

Forecasts for Ireland


TODAY ... The last area of rainfall should make steady progress east this morning and add just 2-3 mm to the overnight totals (5-10 mm), then partial clearing will follow as winds veer more to the west and pick up to 40-60 km/hr. Highs may only reach 15 C in the north but should be closer to 19 or 20 C in the south and east, while the west reaches 17 or 18 C. Although it will generally clear up, one or two isolated showers will probably develop near the northwest coast this afternoon.

TONIGHT ... Clear intervals and cool, lows inland 4 to 8 C, coastal and urban locations closer to 10 C.

SATURDAY ... Sunny with cloudy intervals, highs 17 to 20 C.

SUNDAY ... Another clear and cool start, lows similar to those in the "tonight" forecast above, then sunny for east and north, increasing cloud south and west, highs near 19 C except where sea breezes hold temperatures closer to 16 C.

SUNDAY NIGHT ... Rain will spread across the country from early evening in Munster to midnight or later in north Leinster and Ulster, 5-10 mm expected, with lows around 12 C.

MONDAY ... Rain ending, turning rather cool, highs 15 to 17 C.

TUESDAY ... Partly cloudy, breezy, highs near 18 C.

OUTLOOK ... Unsettled by middle of next week, but then indications that it may be slowly turning warmer athrough mid-month and turning very warm at times in the second half of August.

My local weather on Thursday was hazy and hot with highs near 30 C.

Sunday, 13 August, 2017

Forecasts for Ireland


TODAY ... Mostly cloudy, with a few sunny breaks in parts of Leinster and Ulster, some drizzle near Galway Bay could spread a little further inland, but generally a dry day with highs 15 to 18 C.

TONIGHT ... Rain spreading into Munster and south Connacht by evening will then move across other regions before midnight, and about 5 to 10 mm will fall in most places, with lows 10 to 12 C.

MONDAY ... Rain tapering off to showers, then some partial clearing, highs 16 to 19.

TUESDAY ... Partly cloudy, isolated showers, lows near 8 C and highs near 18 C.

WEDNESDAY ... Heavy showers, highs near 19 C.

OUTLOOK ... Unsettled to the weekend, highs 17 to 19 C, possibly a little warmer by the weekend (19th-20th) and into Monday 21st, but with the risk of heavy rain developing.

My local weather cleared up somewhat on Saturday with sunshine less filtered by haze than all of the past two weeks, highs near 23 C. Overcast now with rain moving in (set to last a few hours then back to dry weather next week). A new tropical storm (now Tropical Depression number 8) is forming east of Bahamas.

Tuesday, 15 August, 2017

Forecasts for Ireland


TODAY ... Partly cloudy, isolated showers, more frequent near Atlantic coasts, highs near 18 C. Moderate southwest winds 30-50 km/hr.

TONIGHT ... Increasing cloud, rain spreading into west around midnight and then towards east coast by morning. Lows 12-14 C.

SATURDAY ... Sunny intervals to start, increasing cloud with rain by late afternoon or evening, warmer and humid, highs near 21 C.

SUNDAY ... Partly cloudy, showers, breezy, highs 18 to 20 C.

OUTLOOK ... Becoming somewhat warmer next week, some sunshine in the first few days with highs 21 to 23 C.

My local weather on Monday was partly cloudy with highs near 21 C. Now-hurricane Gert west of Bermuda will continue to push northeast. Remnants will be between Iceland and Ireland by Saturday and may energize the frontal system timed for Saturday evening and overnight although the circulation will begin to fall apart before the core reaches the vicinity of Ulster or Scotland.

So, heading out for a week of holiday and hoping to see the total eclipse on Monday the 21st, back here around the 23rd. Thanks in advance to those who provide some forecasts.
