Forecasts for Ireland


TRENDS for the week of 12 to 18 May 2021 --

-- Temperatures will average about 1 deg below normal, a blend of days being 1-2 below and nights near or slightly above normal.
-- Rainfalls will average 25 to 50 per cent above normal, with parts of the northwest possibly closer to average.
-- Sunshine will average about 50 to 75 per cent of normal values but amounts will be variable from place to place as slow moving cloud systems compete with dry slots offering considerable sunshine. The midlands may see more sunshine than other regions.
-- Wind speeds will be generally rather light to moderate.


FORECASTS

TODAY some showers and isolated thunderstorms will develop over Munster and these will slowly move further east and then northeast, to cover much of south Leinster by afternoon. A separate area of heavy showers has emerged from Scotland into northern Ulster and this will track south into other parts of Ulster and then Connacht during the afternoon. A few places could escape both systems and remain dry. Any morning sunshine will likely fade behind increasing cloud. 10 to 20 mm rainfalls are possible with these disturbances, and some thunderstorms could produce hail. Highs 13 to 16 C.

TONIGHT will see a clearing trend again with showers more isolated, lows 1 to 4 C.

THURSDAY will have new outbreaks of showers and thunderstorms, the central counties seem most at risk for heavier amounts. A slight northerly breeze will feel a bit cooler than these past few days, highs 10 to 14 C.

FRIDAY will have variable amounts of cloud and outbreaks of showery rain, lows 1 to 4 C and highs 11 to 15 C.

SATURDAY will be cloudy with a few brighter intervals, and showery outbreaks of rain with lows near 7 C and highs around 14 C.

SUNDAY will bring cloudy skies with a few breaks, and heavy showers, isolated thunderstorms, lows near 7 C and highs near 14 C.

MONDAY will be overcast with rain becoming heavy at times, lows near 8 C and highs 12 to 14 C.

The outlook for next week is for this unsettled weather regime to continue with further pulses of heavy rainfall likely towards Thursday 20th and the following weekend. Any improvements later in the month may be rather faint.

My general outlook for summer is fairly simple, this unsettled and rather cool pattern seems likely to persist into parts of June and there could be slow improvement through late June and July with a good chance for the situation to reverse to warm and dry weather at times in late July and parts of August. So the key word there is improving, but at the same time the rather localized nature of the disturbed weather the past few days points to the difficulty of establishing anything much more than a general trend, specific locations could vary in all time scales as we saw yesterday where some enjoyed a lot of sunshine.

Forecasts for Ireland


TRENDS for the week of 14 to 20 May, 2021

-- Temperatures will average 1 to 2 deg below normal values.
-- Rainfall will average near normal to 25 per cent above.
-- Sunshine will average 50 to 75 per cent of normal.
-- Wind speeds will be light to moderate, and wind directions turning more northerly at times.


FORECASTS

TODAY will have some morning sunny breaks, most prevalent in west Munster and parts of Connacht. Cloud will increase around mid-day with overcast skies in most places by afternoon. Some outbreaks of showery rain, more widespread in the north, 3 to 5 mm amounts expected. Rain will spread into west Munster by late afternoon or evening from the west. Highs 12 to 15 C.

TONIGHT will be overcast with occasional rain, 5 to 10 mm expected. Lows 6 to 8 C.

SATURDAY will have widespread showers with a few brighter intervals developing by afternoon, isolated thunderstorms possible in the midlands. Highs 13 to 16 C.

SUNDAY will have some outbreaks of light rain followed by variable cloud and showers or patchy drizzle, turning a bit cooler in light northerly winds, lows 5 to 7 C and highs 12 to 14 C.

MONDAY and TUESDAY will bring variable cloud and a few showers, cool, lows 4 to 6 C and highs 12 to 14 C.

WEDNESDAY and THURSDAY look similar but with some chance of longer sunny spells developing in a few places, temperatures falling slightly further at night mostly, lows 2 to 5 C and highs 12 to 14 C.

FRIDAY and SATURDAY then look partly cloudy and cool with lows -1 to +2 C with local frosts returning, and highs around 13 C.

The OUTLOOK is for warmer weather to develop in the final week of May, with perhaps a return to normal or even slightly above normal temperatures at times (around 20 C).

My local weather on Thursday was sunny and pleasant with a high near 19 C.

Sunday, 16 May, 2021

Forecasts for Ireland


TRENDS for the week of 16 to 22 May, 2021 --

-- Temperatures will average 2 to 3 deg below normal values.
-- Rainfall will average 25 to 50 per cent above normal values.
-- Sunshine will average 50 per cent of normal.
-- Winds will remain fairly light to moderate until Wednesday night but then could become strong for much of Thursday before abating.


FORECASTS

TODAY will be partly to mostly cloudy, with showers and isolated thunderstorms by mid-day and afternoon, rainfalls in the range of 5 to 10 mm for most places, and highs 13 to 15 C.

TONIGHT will become partly cloudy with fewer showers, cool with lows 3 to 7 C.

MONDAY will be partly cloudy with showers, some longer dry spells and sunny breaks could develop and highs will be in the 13 to 15 C range.

TUESDAY will be partly cloudy with showers, lows 2 to 5 C and highs 12 to 14 C.

WEDNESDAY will bring some morning dry spells and limited sunshine then increasing cloud, rain sweeping in from the Atlantic by late in the day as winds increase rapidly. Lows 2 to 5 C and highs 13 to 15 C.

THURSDAY will be windy and wet as an unusually strong Atlantic low hits the west coast and then weakens to drift across the southern half of the country. Northern regions will have very cool temperatures, easterly winds 50 to 80 km/hr and 20-30 mm rainfalls with temperatures steady 8 to 10 C. Southern regions will get into somewhat milder air with spells of heavy rain, possible thunderstorms, and gale force southwest winds in coastal areas 60 to 100 km/hr. These winds may cause some disruption and minor damage to trees. Later in the day the storm will be less intense but showery weather will continue and winds will become northwest 40 to 70 km/hr. Lows near 8 C and highs 12 to 14 C for the south.

FRIDAY will be partly cloudy and cool with passing showers, lows near 6 C and highs 12 to 15 C. Northwest winds will continue for a while before a southwest flow resumes.

The OUTLOOK is rather uncertain, model runs keep changing considerably from one time to the next, and in the past few tries we have seen continued cool and unsettled, warmer and drier, and now a mixture, so the best idea here is to expect a bit of everything in the final week of May, perhaps some partial relief from the cool temperatures but not as certain to escape the cloud and rain.

My local weather on Saturday was sunny and warm with a high near 25 C.

Tuesday, 18 May, 2021

Forecasts for Ireland


TRENDS for the week of 18 to 24 May, 2021 --

-- Temperatures will average 1 to 2 deg below normal values.
-- Rainfall will average near normal to 25 per cent above normal in the inland north.
-- Sunshine will average 75 per cent of normal values.
-- Rather light winds until Thursday then strong winds gradually abating to moderate on Friday, generally moderate wind speeds from then to Monday.


FORECASTS


TODAY will be partly cloudy with just a few widely scattered showers at first, but a somewhat more organized band of showers can be expected by afternoon through the midlands, moving east to reach the east coast by evening. This will bring about 3-5 mm rainfalls to most places. Highs 12 to 15 C.

TONIGHT will bring an end to the showers for a while, and partly cloudy to clear skies will develop again, lows in the 2 to 5 C range.

WEDNESDAY will have some brighter intervals in the morning to mid-day hours, then increasing cloud, just isolated showers mostly in parts of west Munster and northern counties. Winds generally light southerly but increasing by evening to southerly 40-70 km/hr. Highs 12 to 15 C.

OVERNIGHT into THURSDAY periods of rain and strong southwest winds developing, 50 to 80 km/hr, variable cloud with passing showers by mid-day and afternoon, highs in the south 14 to 17 C, but the north will stay in somewhat cooler air and winds will turn more to an easterly direction as low pressure arrives on the west coast by late in the day, leading to a steady rain in the north (10-20 mm amounts generally in all regions).

FRIDAY this disturbance should be steadily moving away into Britain leaving behind a moderate west to northwest flow (40 to 70 km/hr) with partly cloudy skies and isolated showers, cool with temperatures steady around 11 to 13 C.

SATURDAY will be partly cloudy to overcast and cool with outbreaks of showery rain at times, winds westerly at about 40 to 70 km/hr. Lows near 4 C and highs 12 to 14 C.

SUNDAY and MONDAY will be quite cool as winds turn more northerly, and temperatures could be only around 12 to 14 C for highs, with occasional showers.

The OUTLOOK is for drier weather to set in later next week, still unclear whether there will be an accompanying warmer temperature trend or just more sunshine making it perhaps feel a bit warmer even if temperatures don't necessarily come up much. There are some guidance maps suggesting a bit of an easterly flow with this stronger high pressure area, if so that will perhaps lead to an east-west difference of several degrees (14 to 19 C) with the west warmer.

My local weather stayed sunny most of the day with a rapid increase in cloud by evening, and showers just off to our west marking a cold front, gusty south winds during the day and very warm temperatures near 26 C. It will turn a lot colder overnight here and there's some chance of seeing snow mixing in with the cold rain we're expecting, certainly snow will return to local hilltops that have just lost their snow cover in this warm spell.

Forecasts for Ireland


Blog format returns today, the trends are unfolding as expected and basically the same trends as we've seen most of this month will continue for a few more days, followed by a drier trend next week.

An Atlantic low pressure system that would not be out of place in November has been moving steadily towards the west coast. The centre of this low will make a landfall in Galway later this afternoon and then will cross the central counties to emerge into the Irish Sea around Dundalk late tonight.

If you are located near this track, including Galway, most of the midlands and Dublin, expect winds to become more moderate later today when the low is closer, and in some cases there may be a brief calm interval with the low overhead (that more likely in Meath than Dublin). Further north, east winds will continue and will remain in the range of 50 to 80 km/hr. Rain will be steadier further north and more showery in nature further south, but eventually most places will get similar totals of about 20 mm (30-50 mm localized maximum rainfalls could occur over higher terrain especially in Kerry and west Cork).

It will be quite rough off the south coast with winds of 80-120 km/hr, and some of these gusts will reach at least outer headlands if not a little further inland at times in the south. Around Dublin, wind gusts of 70-90 km/hr seem likely for much of the day before that lull begins around midnight. The south coast winds will be south to southwest for most of the day, veering to westerly then northwesterly overnight. The Atlantic coast will also be quite windy although closer proximity to the low centre probably means somewhat more moderate speeds for Clare and south Galway. In some places winds will begin to veer from southeast to southwest later this morning and further north they will back from southeast to northeast, depending on which side of the low track you are located.

Temperatures will be in the 13-15 C range most of the day in the south, could peak a bit higher anywhere that the sun pokes through for any length of time. Along the track of the low would expect cloud to be persistent and temperatures steady 12-13 C. Further north it may be a few degrees cooler in the east winds.

By tonight, the low will be over Leinster and then by morning near the Isle of Man, and this will promote a gradual turn of winds in all regions to northwest, or northerly in east Ulster. These winds will be fairly strong in the range of 60 to 90 km/hr. There will only be small additional amounts of rainfall in this phase of the event. The overnight lows will be around 8 to 10 C.

By FRIDAY the skies will be partially clearing with bands of showers likely in continued blustery northwest winds of 50 to 80 km/hr, temperatures will only recover a few degrees to about 12 to 14 C, and some sunny breaks will be mixed in with passing showers in some places.

Then on SATURDAY, winds will turn back to the south-southwest ahead of another Atlantic low, this one of more modest intensity, but still quite strong for this time of year. Rain will spread in during the day and it will be rather cool with highs only around 13 to 15 C. Rain will be heavy at times overnight into SUNDAY morning and there could be another 10 to 20 mm of rain in places. SUNDAY will become partly cloudy to overcast with winds west-southwest at about 40-70 km/hr, passing showers or outbreaks of light rain, and highs near 13 C. MONDAY will see the dying remnants of this low drifting across Connacht and Ulster, so it will remain unsettled and mostly cloudy with temperatures still quite depressed at around 12 or 13 C.

From about TUESDAY on, there will be a welcome change in the weather, not any large-scale warmup because high pressure is going to stay a bit too far to the west, keeping a slight northeasterly flow in place. That will probably lead to lower temperatures in Leinster and east Ulster than other regions, so would expect several days with highs of about 14 C in the east, 18-20 C in the west responding to longer sunny breaks. There could also be some patchy cloud in the vicinity of the Irish Sea in this otherwise dry spell. Parts of Britain will benefit too, but they will also be somewhat closer to a source of weak low pressure areas that could form over the North Sea into Belgium and Holland, spreading cloud into the southeast and even some rain at times, but that may avoid Ireland either totally or mostly during the latter portions of the week.

Rather than any scenario of a long gradual warming trend that could happen with stalled out high pressure, it looks more like the high will depart for the central Atlantic Ocean in early June and open things back up to unsettled northwesterly flow which cannot be any warmer than average at best (and will likely be a few degrees cooler).

In the central Atlantic now, a low is forming and heading west-southwest towards Bermuda where it could briefly become the first named tropical storm of 2021. Further west, high pressure is stationary over the east coast of the U.S. so the golf event there (PGA Championship) will enjoy some fine settled weather all weekend.

My local weather continued rather cold, with clear skies and a slight frost at dawn, then a steady buildup of cloud ending up with mixed showers of rain and hail by afternoon, highs only around 12 C.

Saturday, 22 May, 2021

Forecasts for Ireland


TRENDS for the week of 22 to 28 May 2021

-- Temperatures will average 2 to 3 deg below normal values.
-- Rainfall will average 50 to 75 per cent of normal.
-- Sunshine will average near normal values.
-- Light to moderate winds will prevail with a few stronger gusts likely late tonight.


FORECASTS


TODAY will have some sunny intervals to start, with a gradual increase in cloud by mid-day and becoming fully overcast this afternoon. Some light rain could develop near Atlantic coasts late afternoon into early evening. Light winds for the first half of the day then a moderate southerly breeze of 30 to 50 km/hr. Highs 13 to 16 C.

TONIGHT will become rather windy with squally showers or outbreaks of moderate rain bringing 5-10 mm by morning. Winds south to southwest 50 to 70 km/hr. Lows near 7 C.

SUNDAY will see the band of heavy showers moving off to the east by late morning, followed by variable cloud and more showers developing, chance of a thunderstorm with hail in some parts of the midlands and Leinster. Highs around 14 C. Winds westerly 40 to 60 km/hr.

MONDAY will be cloudy with a few sunny breaks, and occasional showers, quite cool with lows near 7 C and highs 12 to 14 C.

TUESDAY will become partly cloudy with showers more isolated although continuing to be widespread in east Ulster and north Leinster during the morning. Lows near 6 C and highs 14 to 16 C.

WEDNESDAY will be partly cloudy and a bit warmer, lows near 6 C and highs 16 to 18 C.

THURSDAY and FRIDAY look rather cloudy with the chance of some light showers at times, lows near 7 C and highs around 17 C.

By next weekend (29-30 May) and into Monday 31st, fairly settled and just a touch warmer again with highs possibly close to 20 C well inland, 16 to 18 C near coasts.

Unfortunately there are signs that it will turn more unsettled again in early June but temperatures are currently looking moderate (15 to 18 C on average) which is a bit below June averages but not by a large amount.

They have yet to name the developing tropical storm now close to Bermuda but may do so at any moment as it looks to have reached that status; another candidate being watched in the Gulf of Mexico is running out of time to acquire tropical characteristics but is spreading heavy rainfalls into southeast Texas anyway. My local weather on Friday was partly cloudy and just a bit warmer than the past few days with a high near 16 C.

Monday, 24 May, 2021

Forecasts for Ireland


TRENDS for the week of 24 to 30 May, 2021

-- Temperatures will average near normal values with a rising trend, balancing a start at around 3 deg below normal with a finish where several days are a little above average.
-- Rainfall will vary from 25% or less in Ulster, to 75% of normal in parts of Munster.
-- Sunshine will average near normal values.
-- Wind speeds will be generally moderate at times but mostly light.


FORECASTS


TODAY will bring a mixture of cloud and sunshine, probably longer bright spells further north as there will be more widespread showers and a few thunderstorms across Munster and south Leinster. Rainfalls of 5-10 mm will be typical there, but trace to 5 mm further north. Rather cool, highs only 12 to 15 C.

TONIGHT will become partly cloudy in most areas, with light rain at times across the south, lows near 7 C south to around 3-5 C in Ulster.

TUESDAY will be rather cloudy with some areas of rain lingering to at least mid-day in Munster and south Leinster, but a clearing trend will develop by late afternoon and evening there, with longer sunny intervals all day further north. Highs 12 to 16 C.

WEDNESDAY will be generally dry with partly cloudy skies, isolated showers most likely in the southwest, with lows of 4 to 7 C and highs of 13 to 17 C.

THURSDAY will start out partly cloudy and pleasant in the east and north, overcast in the south and west where outbreaks of light rain will begin during the morning hours and become somewhat heavier by afternoon and evening. This rain may reach the east and north by late afternoon or evening. Lows 4 to 7 C and highs 15 to 18 C.

FRIDAY will see gradual clearing from the west, lows near 10 C and highs 17 to 20 C.

SATURDAY to MONDAY (29th to 31st) will be reasonably warm with Monday looking like it may exceed 21 C, after two days around 19 C or so. This will be a partly cloudy interval with some generous sunny intervals, and only small chances for showers.

Into early June, a warm, humid southeast flow will develop and spread rain into Ireland at times from that direction, and highs will be in the 17 to 21 C range. This may lead to outbreaks of heavy and thundery rain within a few days.

My local weather on Sunday was overcast with a high near 15 C. It wasn't warm enough to be warm and it wasn't cold enough to be cold.

Wednesday, 26 May, 2021

Forecasts for Ireland


TRENDS for the week of 26 May to 1 June --

-- Temperatures will average 1 to 2 deg above normal values with a warming trend.
-- Rainfalls will average 25 to 50 per cent of normal.
-- Sunshine will average near normal although possibly a bit below average in the south.
-- Winds will remain generally rather light with nights often calm.


FORECASTS

TODAY will be partly cloudy and slightly warmer than recent days in most areas, highs 14 to 17 C. There will be some lingering light rain or drizzle in parts of west Munster but this is showing signs of dissipating later this morning too, temperatures will be a bit cooler until the cloud does break up there (12 to 14 C).

TONIGHT will bring some clear skies in the east and north, partly cloudy to overcast in the south and west. Lows will therefore range from about 2-5 C in the north and east, to 7-10 C in the south and west.

THURSDAY will start out with some sunny intervals in the east and north, mostly cloudy in the south and west. A band of light rain will develop and cross parts of the southwest and midlands, leading to a drop in temperatures during the rain, but otherwise highs will reach about 17 C (it may drop off to near 10 C when raining).

FRIDAY this weak disturbance will begin to break up over the east with a few residual showers, followed by partly cloudy to sunny skies, lows near 8 C and highs near 18 C.

From SATURDAY to around TUESDAY 1st of June, the weather will turn warmer with some hazy sunshine each day, and just slight chances of rain mostly from weak fronts near Atlantic coasts later in the period. Highs will be at least 20 or 21 C and could be a few degrees higher inland if there's enough sunshine. Nights will be fairly mild with lows generally around 7 to 9 C although a few inland spots could get briefly down around 2-5 C although with nights as short as they are now, very few will be out and about when those temperatures happen anyway (around 0400-0500 hours).

Some recent guidance seems to be more optimistic about how long this warm spell might last although with such a prolonged cool spell coming to an end it probably wouldn't take much to tilt the balance back to cooler temperatures at some point next week, hopefully this warmth will dig in and take over for a while, as I'm sure the growing season has been held back slightly by all the cool temperatures in April and May.

My local weather was mostly cloudy again with showers on the local radar just to our west but they stayed in place over higher terrain and skies were threatening but remained dry locally. Highs reached about 18 C. There's a full moon tonight here and as it sets around 0400h local time (1100h GMT or 1200 IST) there will be a total eclipse of the moon visible if it doesn't cloud over again. Will have some chance to see at least the first half of this event before the moon sets behind the mountains here. Eastern Asia and Australia will get the best views. If you see the moon tonight in Ireland it will still appear full but no eclipse will occur.

Friday, 28 May, 2021

Forecasts for Ireland


TRENDS for the week of 28 May to 3 June 2021 --

-- Temperatures will average 1 to 2 deg above normal, probably evenly distributed after some different trends cancel each other out (relatively cool in east at first but relatively warm there later).
-- Rainfall will average perhaps 25 to 50 per cent of normal in some parts but more likely in eastern counties with today's rain part of that total, a few places might stay relatively dry further west as rainfall late in the weekly interval is uncertain at least as to timing (think it is likely to happen but which side of 3 June being the question).
-- Sunshine will average at least near normal and some places will do as well as 25 per cent above normal.
-- Light wind speeds will prevail most of the time.


FORECASTS

TODAY will stay cloudy most of the day in Leinster with further rainfalls of 5-10 mm likely, most of that before mid-day with more patchy drizzle expected later on in a slow clearing trend. Some rain may spread into east Ulster at times also. Further west it should be a partly cloudy start and a sunny mid-day and afternoon. This will produce temperatures as low as 13-15 C in Leinster and as high as 18-20 C further west.

TONIGHT will become partly cloudy but misty or perhaps foggy in places in Leinster and east Ulster, lows near 7 C. Where it stays dry today, skies should be partly cloudy to clear tonight with lows 5 to 8 C.

SATURDAY to MONDAY there seems little point in issuing three forecasts since the entire period looks similar in most places, partly cloudy to sunny and relatively warm (especially by recent standards, this will be the first actual warm spell since late March). Highs each day should reach about 20 to 23 C away from any cooling influences of the nearby cooler ocean / sea temperatures which are generally around 12-14 C now. Some rather weak sea breezes could develop around coasts each day. Nights will also be dry and partly cloudy to clear, with lows in the 6 to 10 C range for most, although can't rule out colder readings in the usual cool spots well inland.

By the TUESDAY to WEDNESDAY time frame, that frontal system I discussed yesterday is still making a gradual move north from the Atlantic west of Spain towards western Biscay regions and eventually the south coast of Ireland. Timing on this seems a bit erratic on various model runs and in general it seems to be slowing down to arrive more like late Tuesday into Wednesday now. But eventually it will do two things, first of all, winds will turn more southeasterly which will make some parts of west Ulster and north Connacht the warmer part of the country around mid-week, and also, bands of showers and isolated thunderstorms are likely to push in from the south and end what appears to be a four-day dry spell (after today's eastern rain ends). These may be quite hit or miss as the system does not look overly strong.

Once that lethargic system finishes its drift north through Ireland late in the week, another brief dry spell would follow but then the regime looks increasingly unsettled with reasonably warm temperatures but fairly frequent rain from passing fronts, on a 2-3 day cycle. This, it should be said, is not "carved in stone" and some different evolution would not be entirely unexpected. It does seem that we're just about done with the below normal temperatures for a while anyway.

My local weather (probably well timed as we head from outdoor dining only to somewhat restricted back to almost normal in that regard) was cloudy, windy and at times rather stormy with a fairly decent thunderstorm around 4 p.m. and forked lightning hitting a nearby peak a few times, distant thunder, and briefly heavy rain and strong wind gusts, temperatures rather sultry near 20 C until that hit, but we're up so high here that we get quite impressive cold downdrafts in storms (probably briefly near 12 C). All that has moved on towards the Rockies and another front is heading in from the coast for perhaps a brief encore late tonight, to be followed by a warmer dry spell here as well. I noticed some tornado warnings for eastern OK earlier today, checked the actual reports and luckily it seemed to remain just sub-tornadic for the most part moving through Tulsa and into Arkansas, moderate tree damage and a low human casualty impact which is good. However this system is likely to regenerate further east today.

Sunday, 30 May, 2021

Forecasts for Ireland


TRENDS for the week of 30 May to 5 June 2021 --

-- Temperatures will average about 2 deg above normal values.
-- Rainfall will vary from about 75 per cent of normal in the south and west, to 25 per cent in the north and east.
-- Sunshine will work out near or slightly above normal values.
-- Winds will continue to be light south to southeast much of the time.


FORECASTS

TODAY will be mostly sunny and warm in most places. Some cloud may drift around near coastal areas, sometimes producing a slight mist or sea fog effect, but it may be transient rather than "socked in all day." Highs 20 to 23 C but a few degrees cooler close to the sea.

TONIGHT will be clear with increasing high cloudiness in parts of the west. Lows 6 to 9 C.

MONDAY will be rather cloudy in the west and there could be occasional drizzle near the Mayo and west Donegal coasts. Other areas will have at least partly sunny conditions with the sun sometimes dimmed by variable amounts of higher cloud. Little change expected in temperatures, near 22 C inland, 17 C on some coasts.

TUESDAY will bring only slight changes with partly cloudy to overcast skies, outbreaks of light rain near Atlantic coasts but little accumulation there, and highs 18 to 22 C.

WEDNESDAY could turn quite unsettled, as a frontal system pushes up from the Biscay region, with potential for thunderstorms mixed in with a general band of rain showers lasting several hours as it moves gradually northward through most regions. Heavier rain is likely to hit the south central and inland western counties (15-30 mm there) with smaller amounts expected in Leinster and Ulster. Temperatures around 18 C but one or two places could reach 20 C with enough breaks in the overcast. Winds will temporarily pick up a little to southeast 30-50 km/hr.

THURSDAY will be partly cloudy to overcast with isolated showers, still rather muggy and warm with highs about 19 or 20 C.

The outlook is for fairly bland weather conditions to continue with temperatures not far from 20 C most days, no return to any widespread cool weather is foreseen for a while at least. My forecast for June is for slightly warmer than average temperatures, near normal rainfall and sunshine, with perhaps a trend towards more unsettled conditions in the second half of the month.

My local weather was sunny with a few passing clouds, still a bit cool for late May although the sun felt warm out of the breeze, and highs reached about 17 C. We are heading into a much warmer spell lasting most of the week with predictions of 27-30 C highs.

Tuesday, 1st of June, 2021

Forecasts for Ireland


TRENDS for the week of 1 to 7 June, 2021

-- Temperatures will average 1 to 2 deg above normal.
-- Rainfall will average near normal in parts of Connacht, the midlands and south central counties, 25 per cent above normal in west Munster, and as much as 50 per cent below normal in Ulster.
-- Sunshine will average about 75 per cent of normal values, to near normal.
-- Light winds will continue except for a few intervals of moderate southeast winds late Wednesday, becoming moderate southerly Thursday.

FORECASTS

TODAY will bring some further outbreaks of rain (5-10 mm) in parts of Connacht, spreading at times into west Ulster and west Munster but these will tend to fragment to showers later. Partly to mostly cloudy elsewhere but continued warm and dry, highs 17 to 20 C for most, near 22 C locally in the inland southeast.

TONIGHT will be partly cloudy to overcast and quite mild with a few light showers in the south and west, lows around 10 to 13 C.

WEDNESDAY will bring outbreaks of heavier rain moving in from the south, the south central counties northwest to Connacht will see 10-15 mm, with lesser amounts likely in most of Leinster and Ulster, in fact remaining dry in a few parts of east Ulster until late in the day. Some thunderstorms may be embedded in this band of rain, and highs will be around 19 C.

THURSDAY some further outbreaks of rain in the west and north mainly, with variable cloud and southerly winds at 30 to 50 km/hr elsewhere, lows near 12 C and highs 16 to 19 C.

FRIDAY and SATURDAY will bring another outbreak of showery rainfalls as a rather weak frontal system moves gradually northeast across the country, 2-5 mm rainfalls and highs both days near 19 C.

The further outlook calls for a few more showery episodes from time to time in a southwesterly flow that will be rather cloudy overall, but with some sunshine at times, and near normal temperatures for the period (highs 19-21 C) with rather mild overnight readings.

My local weather on Monday was sunny and hot, with highs reaching 32 C in the nearby valley, and 28 C at my location (we were into the hotter temperatures for a while) and there was some cloud build ups but no rain with them by evening.

Thursday, 3 June, 2021

Forecasts for Ireland


TRENDS for the week of 3 to 9 June 2021

-- Temperatures will average 1 to 2 deg above normal.
-- Rainfall will average 25 to 50 per cent of normal.
-- Sunshine will average near normal values.
-- Winds rather light except sometimes moderate south to southwest near Atlantic coasts.


FORECASTS


TODAY will be partly cloudy to overcast in most areas, with only a slight chance of brief showers, highs 18 to 20 C. There will be a higher chance of showers in Atlantic coastal districts and by afternoon also in parts of Ulster.

TONIGHT will be partly cloudy with lows 8 to 10 C.

FRIDAY will be partly cloudy with occasional showers in western counties, highs 17 to 20 C.

SATURDAY will be partly cloudy with isolated showers or thunderstorms, lows near 8 C and highs 18 to 21 C.

SUNDAY will be partly cloudy to sunny at times, after some dense morning fog patches, lows near 7 C and highs inland 20 to 23 C, coastal areas remaining cooler (15 to 18 C).

OUTLOOK for next week calls for gradually rising temperatures towards quite warm values in the mid 20s at times by later in the week, with only slight chances for rain as weak frontal remnants pass by.

My local weather stayed sunny and hot with the high reaching a scorching 37 C in the valley, 33 C at my location. We are due to have one more hot day then a gradual return to more normal June temperatures and scattered showers by the weekend here.

Saturday, 5 June, 2021

Forecasts for Ireland


TRENDS for the week of 5 to 11 June 2021 --

-- Temperatures will average 1 to 2 deg above normal values, warmest late in the week.
-- Rainfall will average only 10 to 25 per cent of normal.
-- Sunshine will average near normal, for a dry pattern it is also somewhat cloudier and some coastal areas may not reach the normal amounts of sunshine due to low cloud from sea fog or marine layers.
-- Winds will be generally light but occasionally moderate southwest.


FORECASTS


TODAY will be cloudy with some sunny intervals, rather muggy, with a few light showers but chance of a heavier shower or thunderstorm developing in one or two spots, most likely inland north and east Ulster. Many places will remain almost dry with just a few spots of drizzle perhaps. Highs 16 to 19 C.

TONIGHT will become partly cloudy and could see clear intervals but then fog or low cloud following, lows 6 to 10 C.

SUNDAY will have some sunshine at times once the low cloud, mist and fog clear away. There could be a few isolated showers later on in the west and north. Highs 17 to 20 C.

MONDAY will bring variable amounts of cloud and a slight chance of showers, again most places likely to have a dry day but one or two heavier showers possible locally. Lows near 8 C and highs near 20 C.

TUESDAY will be partly cloudy to overcast and some outbreaks of rain seem likely from a weak frontal trough, amounts generally only 1-4 mm, lows near 12 C and highs near 20 C.

From WEDNESDAY to about SATURDAY 12th, a more settled and quite warm interval will follow, with highs creeping up into the 22-25 C range at times.

This will likely be followed by a somewhat more unsettled period, with more frequent frontal passages bringing some rain although still not more than average for mid-June. Temperatures mid-month will settle back into a more normal range.

My local weather on Friday saw a gradual end to the hot spell, it was still quite warm with bright sunshine to mid-afternoon and highs near 27 C, then fully overcast later, more comfortable with evening temperatures near 20 C. A fairly active cold front is heading in for the late overnight which means we might get woken up by thunder at some point around sunrise (backing up my files just in case).

Monday, 7 June, 2021

Forecasts for Ireland


TRENDS remain the same, temps 2-3 deg above normal, little if any rainfall, rather cloudy but perhaps enough sunshine to approach the June normals (5-6 hours a day), and moderate southwest winds much of the time.


FORECASTS

TODAY will feature some sunny intervals and rather warm highs of 19 to 22 C. It may start out rather cloudy especially near south and west coasts, and some places could have persistent low cloud from the onshore "marine" flow, but further inland and near the east coast it should be at least bright with variable cloud, if not sunny. Winds southwest 30-50 km/hr.

TONIGHT will become more cloudy in general with outbreaks of light rain, drizzle, and formations of mist or fog, quite muggy with lows 12 to 15 C.

TUESDAY will be cloudy with a few brighter intervals, drizzle or light rain at times, only 1-3 mm likely from this however, and muggy with highs 18-22 C.

WEDNESDAY will bring somewhat longer bright intervals and sunny spells, with less mist or drizzle in the same humid southwesterly flow, lows 12 to 15 C, highs 19-23 C.

THURSDAY to about SUNDAY will probably be a touch warmer still with some sunshine likely each day, fairly long sunny intervals possible in the east at times, and quite humid too, lows 13 to 16 C and highs 20 to 25 C. Winds will be generally a bit stronger south to southwesterly 40 to 60 km/hr.

By late Sunday or early MONDAY (14th) a strong cold front will arrive, winds will turn more northerly behind this, as low pressure dives southeast into the Biscay and Iberian regions, causing this front to drag to a halt over Britain by late Monday 14th, which may keep Ireland under cloud and a light rain at times (heavier rain likely where the front eventually stalls from France into Britain). This set-up will persist for a few days then will be followed by more unsettled conditions and there are some signs of quite a cooler turn to the weather after the June summer solstice.

So would expect highs in the 15 to 19 C range in the week of 14-20 June and perhaps a touch lower than that towards the following week.

My local weather was cloudy, cool and showery at times with highs only 12-14 C, quite a contrast to the mid-30s we had here for three days last week.

Wednesday, 9 June, 2021

Forecasts for Ireland


TRENDS for the week of 9 to 15 June, 2021 --

-- Temperatures will average 1 to 3 deg above normal, the higher values likely to be in Leinster and east Ulster, midlands and east Munster, also more of an anomaly for overnight lows which may be 3 to 5 above normal.
-- Rainfalls will average only 25 per cent of normal in parts of the west and southwest, also into Ulster, with even lower values likely for the east and southeast, some parts of the midlands.
-- Sunshine will vary from only 50 per cent of normal in the west and north, also near the south coast, to closer to normal totals in the east and parts of the midlands.
-- Winds will be generally moderate south to southwest, although in the lower end of the moderate range most of the time.


FORECASTS

TODAY will be mostly cloudy with a few brighter intervals, rather warm and muggy, with a few more outbreaks of light rain more frequent across the south this morning and at times in the west and north by mid-day and afternoon. Amounts will be generally 2 to 5 mm in these areas, and trace to 2 mm in other regions. Highs 15 to 17 C in the cloudier west and south, northwest; 18 to 22 C in the midlands and east. Winds south to southwest 30-50 km/hr.

TONIGHT will be overcast with drizzle at times, rather warm and humid, lows 13 to 17 C.

THURSDAY will also be rather cloudy but with slightly longer bright spells or sunny intervals in the same parts of the country as today, with probably fewer outbreaks of light rain as well. Highs generally 19 to 23 C.

FRIDAY and SATURDAY will continue this slow clearing trend with the widespread cloud becoming a bit less uniform each day leading to some quite prolonged sunny breaks in the east and some sunny intervals in previously cloudy areas further west also. Temperatures will continue a slow rise with highs by Friday 20 to 24 C and by Saturday into the 21 to 25 C range. Nights will continue quite warm with lows 13 to 17 C. Winds will start to pick up slightly each day and may reach 40 to 70 km/hr in exposed coastal areas.

By SUNDAY there may be some showers back in the picture at least for parts of the north and west, but it will remain quite warm especially in the southeast with highs once again 21 to 25 C.

MONDAY will be partly cloudy to overcast with fresher westerly winds and highs 15 to 20 C. Some showers may continue in the north and west.

By TUESDAY (15th) a larger change in the weather pattern will begin as cooler air arrives, and possibly rather gusty southwest to west winds, with more widespread showers advancing gradually further east. Highs around 18 C.

From next Wednesday (16th) on, the pattern may become quite a bit cooler with highs only 15 to 18 C and more frequent outbreaks of light rain, with winds sometimes rather gusty from the west to northwest.

My local weather on Tuesday was partly cloudy and a bit warmer than recent days with highs near 20 C.

Friday, 11 June, 2021

Forecasts for Ireland


TRENDS remain similar, warm for about another week or so, rather dry although cloudy and humid especially in the west, with a slowly increasing chance of rain later in the outlook. The trend beyond the week we normally track is of course less reliable but it looks rather poor, hoping it will reverse.

FORECASTS

TODAY will be partly cloudy in the east to mostly overcast in the west with a few more bright spells than has been the case recently. A few showers will pass by to the north, small amounts of rain likely with them however. Highs about 22 C in some parts of the east, 20 C midlands, 18 C south and west coasts and some parts of the north which will be clipped by a slightly cooler air mass briefly, but that won't make much progress south. Breezy at times, west-southwest 40 to 60 km/hr especially in areas close to the Atlantic.

TONIGHT could feature a few clear intervals but rather cloudy to the west and north again, lows 13 to 16 C.

SATURDAY will turn slightly warmer again with hazy sunshine in many areas, still some low cloud around especially early in the day, breaking up gradually by mid-day where it is a factor. A few coastal locations could remain under low cloud or sea fog but even by the sea there is some chance of sunshine and warmer temperatures. Highs could reach about 25 C in the east, and 19-22 C in other regions.

SUNDAY will start out warm and bright with some sunny intervals, then cloud will increase as a weak front arrives, bringing scattered showers, and a slight chance of a brief thunderstorm, nothing too heavy is expected from this, as the air mass coming in behind the front is almost identical to this current one. Lows near 17 C and highs near 23 C except a few degrees cooler near some coasts.

MONDAY will be a somewhat less humid day and could turn out quite sunny in places, the main difference between this new regime and the current one is humidity levels are going to drop a little, expect lows around 14 C and highs in the range of 19 to 23 C.

TUESDAY will probably be the last warm day for a while, as a more active front approaches, so with increasing cloud and a stronger southwest wind developing, rain may arrive later in the day, after highs near 23 C.

The OUTLOOK for the mid-week and later on towards the weekend of 19-20 June is for cooler weather, unsettled at times with threats of heavier rainfalls especially towards the following week. Highs will be back down into the teens and could be rather cool for late June, so a reversal of the current trend seems to be in store.

My local weather was rather cloudy again with a few moments of sunshine as clouds covered about 90% of the sky most of the day. This cooler air mass is feeding into a very strong disturbance over North Dakota and southern Manitoba, which has some severe storms and heavy rain producing cells developing overnight, with 35 C hot and humid air to the south of the border and temperatures closer to 18 C ahead of a warm front, so it could produce some flooding rainfalls in places. Some wind gusts to 130 km/hr were reported a few hours ago in western North Dakota and the radar imagery looks like heavy hail is in the mix too.

Sunday, 13 June, 2021

Forecasts for Ireland


TRENDS remain similar, slightly cooler after warmth today, then more significantly cooler after mid-week, it should all average out near normal. Rain will be spotty at first but will begin to cover more of the east late in the week, even so few places will get more than half of a normal weekly rainfall. Sunshine will be fairly close to normal with drier air masses not as full of low cloud as recent days. Winds sometimes rather moderate.


FORECASTS


TODAY will feature some very warm sunny intervals in parts of the east and south, with the inland southeast looking most likely to hit the highest readings around 24-25 C. Further north and west, more cloud likely, leading to some sporadic light rain later on, but rather warm and humid there, highs 19-22 C. Rainfalls where they occur only about 2 to 5 mm.

TONIGHT some further advance of the rain is likely into parts of the midlands and northeast, rather spotty showers late overnight in the south and east. It will be a muggy night with lows only dropping to about 17-18 C in many areas.

MONDAY will see the weak front moving on during the morning hours leading to a bright and less humid day with pleasant temperatures around 20 C. Moderate westerly winds likely.

TUESDAY will start out dry with a few sunny intervals in the east and south, but cloud will arrive by mid-morning in the west followed by outbreaks of light rain. Lows of 12-15 C will be followed by highs in the 21-23 C range in parts of the east, near 20 C midlands, but falling back from 18 C to about 14 C in parts of the west as cooler air sets in there.

WEDNESDAY the cooling trend will advance into most other regions and there could be scattered outbreaks of light rain although guidance suggests largely dry in Ireland, as heavy rain will be more concentrated off to the southeast heading towards parts of Britain. It will be a fairly average temperature pattern with lows near 10 C and highs near 19 C in some parts of the east and south, 17 C north and west.

THURSDAY and FRIDAY look just a bit cooler but with some sunny breaks, isolated showers and winds turning more to the northeast as that disturbance over Britain deepens slowly and moves towards the North Sea. While they get some heavy rain in places, Ireland will only have scattered 1-3 mm amounts. Lows near 8 C and highs near 17 C both days.

SATURDAY is likely to become wet as an Atlantic front merges with another low moving north out of France. Some time around the weekend (19th-20th) there could be outbreaks of heavy and possibly thundery rainfall in the east if these fronts stall over that part of the country. Temperatures will be fairly steady night and day in the 13-16 C range.

SUNDAY this rain may continue or else end around mid-day with a slow clearance, in areas further west. Staying rather cool with highs 13-16 C.

The following week looks rather unsettled and cool for late June with highs generally around 15-18 C. That takes us to near the end of June when it could turn quite wet.

My local weather on Saturday was partly cloudy with heavy cloud buildups over local hills that looked capable of generating thunderstorms but these clouds remained rather inactive anyway with just a few raindrops locally, probably some heavier showers over higher terrain nearby. It was a bit warmer with the sunny start to the day allowing temperatures to reach 20 C before it clouded over.

Had a view of a very thin crescent moon this evening in the west-northwest at sunset, barely catching any sun on its lower right portion but the "earthshine" from the reflection off Greenland and other northern ice made the rest of the moon's globe quite easy to see against the twilight sky.

Tuesday, 15 June, 2021

Forecasts for Ireland


TRENDS for the week of 15 to 21 June 2021 --

-- Temperatures will average about 1 deg below normal values.
-- Rainfall will average 50 to 75 per cent of normal.
-- Sunshine will average 50 to 75 per cent of normal.
-- Winds will be generally rather light, sometimes more moderate around late Saturday and early Sunday.


FORECASTS

TODAY will start out dry and bright in some parts of the east with cloud increasing later this morning, otherwise a mainly cloudy day for most regions further west, with rain pushing in gradually, reaching most regions by later this afternoon, but amounts while moderate in the north (5-10 mm) are expected to be rather slight across much of the south (2-5 mm at most). Highs will range from 17 C in the west to 22 C in the east.

TONIGHT the rain will continue to fragment to showers while moving east, and most places will become dry again before sunrise, with lows of about 10 C.

WEDNESDAY will be a rather cloudy day with some sunny breaks, occasional light rain more frequent in parts of the east during the morning, but not much accumulation, and somewhat cooler with highs only 14 to 17 C.

THURSDAY will be cloudy with sunny intervals and isolated showers, cool with lows near 7 C and highs near 16 C.

FRIDAY may see more sunshine than cloud, with light winds and lows of 7 C, highs near 18 C.

SATURDAY will bring increasing cloud and rain by afternoon or evening in most regions (an earlier start to the rain is likely for the west coast), lows near 8 C and highs near 16 C. Some moderate southerly winds will set in during this rainfall, 40 to 60 km/hr.

SUNDAY will be cloudy with showers, brisk west to northwest winds developing, and lows near 10 C, highs 14 to 16 C.

The outlook for the following week is generally rather cool and unsettled. Throughout both weeks of the forecast, there would likely be heavier rainfalls in parts of Britain as lows move in there from France, with the southeast at risk of localized flooding.

My local weather on Monday was sunny and hot again with highs near 30 C. A few thunderstorms have once again developed in the evening portion of the day and one just rumbled past while I was typing this up. It seems to have dissipated now though. A second tropical storm (Bill) has developed north of Bermuda, but is not predicted to have much of an impact before it also dissipates.

Thursday, 17 June, 2021

Forecasts for Ireland


TRENDS for the week of 17 to 23 June, 2021 --

-- Temperatures will average 1 to 2 deg below normal.
-- Rainfall will average 50 to 75 per cent of normal values.
-- Sunshine will average 50 to 75 per cent of normal.
-- Winds generally rather light through the interval.


FORECASTS

TODAY will start out sunny in some central and eastern counties, turning cloudier by afternoon, with isolated showers developing and highs 16 to 18 C. Further west, more frequent showers will develop more rapidly this morning, and one or two may turn locally heavy but overall about 3-5 mm rainfalls are expected in the west, with highs near 17 C.

TONIGHT will feature some clear intervals and it will turn quite cool with lows only 4 to 7 C. Patches of mist or fog will develop in low-lying areas inland.

FRIDAY will bring a mixture of sunshine and cloud, with light breezes and highs 17 to 19 C.

SATURDAY will see increasing cloud in the east, overcast skies in the west, and a gradual onset of light rain which may only extend as far inland as the midlands by late in the day from both the west coast and the south coast, lows near 8 C and highs near 16 C.

SUNDAY will bring intervals of rain, heavier in the southeast than most other places, with 5-15 mm potential across the country, and it will remain rather cool with lows near 8 C and highs near 16 C.

MONDAY will see the gradual end of this showery regime with winds turning more northerly, lows near 7 C and highs around 16 to 18 C.

TUESDAY and WEDNESDAY may bring a slight improvement to partly cloudy skies and only isolated showers with highs still around 18 C. Later in the week, more showers are likely and stronger westerly to northwesterly breezes will develop, with a slight drop in the temperature to around the mid-teens again.

This pattern seems fairly locked in and there is no real sign of any return to warmer weather as we saw last week when temperatures were above normal for a spell. Just for your interest, the summer solstice this year is timed for 0432h IST on Monday 21st (according to the timeanddate.com website). That would be just around sunrise on Monday. In my time zone it will be late Sunday 20th. My local weather on Wednesday remained cloudy and rather cool with passing showers in the vicinity, although dry most of the time, with a high near 17 C.

Saturday, 19 June, 2021

Forecasts for Ireland


TRENDS for the week of 19 to 25 June, 2021 --

-- Temperatures will average about 1 degree below normal values.
-- Rainfall will average about 50 per cent of normal.
-- Sunshine will average 50-75 per cent of normal.
-- Wind speeds will remain generally light.


FORECASTS

TODAY will be cloudy with a few brighter intervals. Some light rain will brush a few parts of the west coast from time to time, accumulations of only about 1 mm expected there, most other locations will remain dry. Highs 16 to 18 C.

TONIGHT will be cloudy with a few outbreaks of light rain or drizzle, heavier near the southeast coast towards morning. Lows 8 to 10 C.

SUNDAY will be mostly cloudy with a few afternoon sunny breaks, and scattered outbreaks of light rain, now only expected to be 5-10 mm at the most. Highs near 17 C.

MONDAY will remain cloudy over parts of the south and east with a few more intervals of light rain in the southeast coastal counties, but clearing there later in the day; the rest of the country should be dry and partly cloudy to sunny further north, lows near 7 C and highs near 17 C.

TUESDAY will be sunny with cloudy intervals, lows 4 to 7 C and highs 16 to 21 C.

WEDNESDAY will bring increasing cloud, some guidance shows rain arriving, but there is uncertainty on timing, it could be delayed to Wednesday night or Thursday morning. Lows near 8 C and highs near 18 C.

THURSDAY and FRIDAY look rather unsettled with a few showers, highs near 17 C.

The latest guidance shows some signs of an easterly flow developing after that weak disturbance moves further south, which would replace any cooling trend with more of a seasonable dry interval with pleasant temperatures near 20 C. Hoping this trend will dig in and cooler air stays up north.

My local weather on Friday was sunny with increasing amounts of high cloud, quite warm at 25 C. The heat wave continues in the desert southwest with more records set again on Friday in the range of 47 to 49 C. The coast continues to be much cooler however with highs around southern California ranging from 20 C along the shore to about 30 C in suburbs further inland, then you get into the 40s across the hills into the desert regions.

Monday, 21 June, 2021

Forecasts for Ireland


TRENDS for the week of 21 to 27 June remain similar, temperatures just slightly below average for late June, rainfall may creep up fairly close to normal eventually, and sunshine for most will be a little less than normal although quite variable (as we saw on Sunday where Dublin had quite a long sunny stretch, not that far away it was cloudy much of the time).


FORECASTS

TODAY will be mostly cloudy with some clearing developing from Ulster southward around mid-day. The remnants of a weak front will bring just a little more rain to a few parts of north Leinster and the midlands, amounts not expected to be much more than 1-2 mm. Highs around 17 C.

TONIGHT will become partly cloudy then clear, and it will become rather chilly with lows 4 to 7 C.

TUESDAY will start out sunny and become cloudy by afternoon with rain across some parts of the north and then later central counties. Highs 18 to 20 C.

WEDNESDAY will see the last of that rain fragmenting to showers over Leinster then slow partial clearing will set in from the west this time, lows 8 to 10 C and highs 16 to 18 C.

THURSDAY will see more frequent showers and highs between 17 C and 19 C.

FRIDAY will be partly to mostly cloudy with showers, and highs around 17 C.

The outlook for the weekend of 26-27 June is partly cloudy and near average for temperatures (18-20 C).

My local weather was sunny and very warm on Sunday with low humidity, highs around 30 C.

Wednesday, 23 June, 2021

Forecasts for Ireland


TRENDS for the week of 23 to 29 June 2021 --

-- Temperatures will average near normal and perhaps slightly above normal in some eastern counties.
-- Rainfall will average 50 to 75 per cent of normal values.
-- Sunshine will average near normal amounts.
-- Winds speeds although generally light will sometimes be more moderate in western counties in particular.


FORECASTS

TODAY will start out quite cloudy with some further showers likely in Leinster and east Ulster. This rainfall will eventually total around 5-10 mm and will end with drizzly intervals mid-day followed by partial clearing, a trend which will develop a lot earlier further west. Highs near 20 C where sun breaks through, 17-18 C under more persistent cloud.

TONIGHT will become partly cloudy with some longer clear intervals giving a good view of the full moon. Lows will be around 7 C.

THURSDAY will see increasing cloud leading to outbreaks of light rain more persistent in the north (5-10 mm expected there). Highs will vary from 17 C in the north to 21 C in the south.

FRIDAY will turn cooler with a few showers in a moderate at times brisk northeast breeze (40-60 km/hr). Lows near 9 C and highs near 17 C.

SATURDAY will be partly cloudy to overcast with a few showers, less windy but similar temperatures to Friday, lows around 10 C and highs around 17 or 18 C.

SUNDAY is not guaranteed to be dry but the odds seem to be tilting more towards a fairly good outcome with only isolated showers in a northeast wind flow, partly cloudy skies, lows near 8 C and highs near 20 C except a bit cooler in the north and near the east coast.

The uncertainty about next week has also shifted a bit more towards a settled outcome with fairly good temperatures near or a little above seasonal averages which would mean highs reaching the low 20s. However the uncertainty has not really gone away and this may tilt back in some other direction before much confidence can be attached to next week's outlook.

Similarly, early July now looks a bit better in general than was indicated a day or so previously.

My local weather is turning into a very hot spell breaking records in this region, what we often get in late July or early August here has already settled in and we had another sunny, hot and dry day on Tuesday with a high near 32 degrees. Forecasts are indicating values closer to 40 C by the weekend. This may be too much information but I don't have that many more items of clothing to discard at this point.

Friday, 25 June, 2021

Forecasts for Ireland


TRENDS for the week of 25 June to 1 July, 2021

-- Temperatures will be near normal in the north and west, to 1.0 deg above normal in the east.
-- Rainfalls will be slight, 25 per cent of normal for most areas.
-- Sunshine will be near average or even a bit above in some places.
-- Wind speeds will increase a little today but will then return to less blustery values over the weekend and next week.


FORECASTS

TODAY will be partly cloudy with a few isolated showers in east Ulster and Leinster, possibly a few other locations, but sunshine will be somewhat more generous in the west for a change (it has been quite a dull month in western counties so far, brighter in the east). Highs around 17 C with rather blustery northerly winds (sometimes backing to north-northeast near the Irish Sea coasts) of 40-60 km/hr.

TONIGHT will be partly cloudy with showers dying out, lows around 7 C.

SATURDAY will be partly cloudy to sunny with better chances of full sunshine towards the west and north. Isolated showers may return to the southeast. Less windy although continued north to northeast in direction. Highs near 18 C.

SUNDAY will be sunny with cloudy intervals, and a bit warmer, lows near 8 C, highs near 20 C.

NEXT WEEK is looking quite good for most areas, while Britain sees a lot of cloud and (in the south mainly) rain from low pressure over northern France, Ireland should remain outside that system's influence most of the time with partly cloudy to sunny skies each day and rather light winds as high pressure won't be too far away to the west then overhead during the second half of the week. Highs each day should be around 21 to 23 C, nights will be seasonable with lows around 6 to 9 C.

Towards the weekend of 3-4 July this settled pattern may break down at least slightly with more cloud and the chance of showers, but even then it may remain at least partly cloudy rather than overcast.

My local weather was mostly sunny, breezy and very warm with highs near 30 C. It's only going to get hotter here each day for several days.

Sunday, 27 June, 2021

Forecasts for Ireland


TRENDS remain similar, mostly dry, near normal temperatures, and average amounts of sunshine.

FORECASTS

TODAY will bring a mixture of cloud and sunshine, the cloud a bit more prevalent near the Irish Sea coasts and inland as far as the midlands, sunshine likely to reach a maximum in west Munster and some parts of Connacht. Northeast breezes will continue so highs will reach about 21 C further west, 17 C near the east coast. Showers will not be widespread, if any occur they will most likely be near the Wicklow and Slieve Bloom mountains.

TONIGHT will be partly cloudy with lows 7 to 10 C.

MONDAY will be partly cloudy to sunny, rather similar to today, perhaps a degree or two warmer with a range of highs from 19 C east to 23 C west.

TUESDAY will continue partly cloudy to sunny with a similar temperature range and isolated showers. (lows 7-10 C and highs 19-23 C).

WEDNESDAY and THURSDAY will likely have somewhat more active shower outbreaks in the inland south mainly, as a weak frontal zone develops due to the push south of a slightly cooler high pressure centre. Although this activity is expected to be hit or miss, a few locations could see 5-10 mm brief downpours, most likely to be about 30-50 kms inland from the south coast across Cork, south Limerick, south Tipps and north Waterford. Otherwise many areas will stay dry with some sunshine each day, lows 8 to 12 C and highs 18 to 22 C.

By FRIDAY a more organized disturbance may develop and end this dry spell for larger portions of the country, although more in the south than further north, and temperatures will remain similar.

From the weekend of 3-4 July on, the pattern looks a little more unsettled although changes week to week may be rather subtle, the overall tendency looks like a cooler and wetter theme into mid-July.

My local weather has turned almost dangerously hot, at my location the maximum was 38 C and several other places in British Columbia (as well as most of Washington and Oregon states) were above 40 C. This is expected to persist for a few days now and even when it breaks down around Friday 2nd, the "cooling" will only be back to the low 30s.

The skies are clear with scattered small cumulus, no thunderstorms developing in this superheated air mass yet, if they do later in the spell, a severe forest fire situation could develop as said storms would probably be rather sporadic rain producers and widespread lightning their main feature. Rather fearing the outcome here as the forests have dried out in this unusually hot and dry second half of June. No major fires to report anywhere yet though, but all it would take is an unattended campfire and since everyone has taken to the lakes and campgrounds, that seems almost inevitable. Heading out now to watch the moon and Saturn rising over nearby hills. Maybe you caught them earlier in the past night, tonight the Moon will be passing near Jupiter but that will be visible only after about 0100h local times around the northern hemisphere.

Tuesday, 29 June, 2021

Forecasts for Ireland


TRENDS for the week of 29 June to 5 July 2021 --

-- Temperatures will average near normal to perhaps 1 deg above normal in some eastern counties.
-- Rainfalls will average 50 to 75 per cent of normal values.
-- Sunshine will average near normal, although a few spots in the west and north could run slightly below average.
-- Generally quite light wind speeds until the weekend, then somewhat more moderate at times.


FORECASTS

TODAY will be partly cloudy on average, more sunshine to the east and south, more persistent cloud this morning in parts of the north and west. Some light drizzle possible in this morning cloudiness, but brighter spells likely by afternoon. Highs near 18 C under more persistent cloud, to 23 C where sunshine most frequent.

TONIGHT will become partly cloudy to clear at times, with fog patches forming, lows 8 to 10 C.

WEDNESDAY and THURSDAY will be partly cloudy to sunny and rather warm in many places, highs reaching 21 to 24 degrees. The overnight low Thursday morning will be around 8 to 10 C.

FRIDAY will bring increasing cloud and rain by late afternoon or evening, 5 to 10 mm expected, lows near 12 C and highs near 19 C in the west to 22 C in the east.

SATURDAY will be partly cloudy to overcast with occasional showers, but also some brighter intervals, lows around 12 C and highs around 18 to 20 C.

SUNDAY will be partly cloudy to overcast with showers, lows near 12 C and highs near 19 C.

NEXT WEEK is looking more unsettled with somewhat cooler temperatures and highs closer to 18-20 C.

My local weather remains extremely hot, more all-time records were set all over this region on Monday and the high locally was 42 C under slightly hazy blue skies. Except for a few days that I've been in the desert southwest in the summer, this is probably the hottest weather I've experienced, certainly in Canada because we just set a national record again for the second consecutive day (at another location in B.C., 48 C). If you're a weather buff, you'll know what this means, I am right under the "heat dome" of about 597 dm with thicknesses around 594 dm. Most of this region is elevated and a fair portion is above 1500 metres so the 850 mb temperatures around here can be just ground temperatures which at that elevation were around 35 C. My own elevation is more consistent with perhaps 900 mbs. Anyway, this is supposed to last a few more days then morph into something closer to our regional normal for early July, which will be a welcome development.
