Forecasts for Ireland
TRENDS for the week of 31 May to 6 June 2020
-- Temperatures will average about 2 deg above normal, with a trend from very warm at first to cooler than average by end of the interval.
-- Rainfall will average 25 to 50 per cent of normal values.
-- Sunshine will average near normal values to 25 per cent above normal in parts of the south and east.
FORECASTS
TODAY will be very warm again with hazy sunshine, some intervals of higher cloud dimming the sunshine at times. There is a slight risk of isolated shower activity near seabreeze boundaries in western counties but it would be quite limited in coverage. Highs 24 to 27 C except slightly cooler near some coasts.
TONIGHT will be hazy and warm with lows dropping only into the 12 to 15 C range.
MONDAY will also be hazy and very warm with highs near 25 C, and the slight risk of isolated showers in the west.
TUESDAY will see some outbreaks of showery rainfall in the north, and the warmer air will hold on for part of the day in the south and some central counties, leading to a rather large range of temperatures from 17 C in the north to 24 C in the inland south.
WEDNESDAY will become considerably cooler in all regions with moderate north to northeast winds and showers, highs near 17 C.
THURSDAY will be partly cloudy with highs 16 to 19 C.
FRIDAY and the following weekend will be rather cool and breezy with some outbreaks of light rain, and it will feel much colder than this current warm spell with highs barely above 12 C in some areas, 15 to 17 C at the highest near south coast.
The cooler trend will not necessarily dominate all of June. The warm dome is being pushed further west but it may not be entirely finished with its work, and could return for brief warmer spells in June, but certainly the overall trend is towards cooler weather. So the long-range forecast for June calls for temperatures near normal or slightly below, with a certain amount of variability, and also near normal amounts of rainfall instead of the dry conditions we've been seeing.
My local weather got quite active around 9 to 10 p.m. on Saturday with frequent lightning and some briefly heavy rainfall after a generally dry and sometimes sunny day with a high near 24 C. The storm activity is widespread in both B.C. and Washington state and may continue off and on through Sunday before much cooler air settles in. The freezing levels had risen above peak levels but are coming back down to around 1500 metres by late Sunday.0 -

Forecasts for Ireland
TRENDS remain similar, temperatures adjusting towards normal then below normal by end of the week; rainfall may make a gradual return and sunshine will be generous at first, then cloudier weather in general after mid-week.
FORECASTS
TODAY will be sunny and very warm, isolated showers may develop near western sea breeze boundaries, but generally quite a dry picture with highs 25 to 28 C.
TONIGHT will be clear and warm with lows eventually dropping to 12 C.
TUESDAY will see some increases in cloud in the north especially, with a cooler trend there, but one final day of this long warm spell for the south. Highs will reach 22 to 25 C in the south, 15 to 18 C only in parts of the north, with afternoon and evening showers developing.
WEDNESDAY will turn considerably cooler with north-northeast winds 40 to 60 km/hr, showers, and morning lows 7 to 9 C with afternoon highs 15 to 17 C.
THURSDAY will be less cloudy and likely dry in most places, but only a slight recovery in temperature to around 18 C.
FRIDAY will see another push of somewhat cooler air again, with highs 15 to 17 C and a few showers.
The WEEKEND could turn even cooler with a full-on northerly air flow bringing temperatures down to 13 to 15 C and some rain at times.
The OUTLOOK calls for a mixture of these occasionally very cool intervals with somewhat closer to normal conditions at times as the warm dome that is now overhead retreats to the central Atlantic from where it might try a few weak sorties but it certainly won't be the dominant player as it has been recently.
My local weather on Sunday was much cooler than previous days, with the overnight rain (about 15 mm) ending but mostly cloudy skies and temperatures only 8 to 10 C in its wake. Some creeks in nearby regions went on rampages after the rain and high level snow melt, and have forced some evacuations; others (mostly around Grand Forks, B.C.) got off a bit lighter than expected so far as the thunderstorm complex had some local areas of heavier or lighter rainfall associated.0 -
Tuesday, 2 June, 2020
Forecasts for Ireland
TRENDS for the week of 2 to 8 June, 2020
-- Temperatures will average 1 to 2 deg below normal values, even though today will continue well above normal.
-- Rainfall will average 50 to 75 per cent of normal values.
-- Sunshine will average 75 per cent of normal values.
FORECASTS
TODAY will continue sunny and very warm in most of the country, but cloud will slowly spread a bit further south from where it is already established in parts of Ulster and northern Connacht. Eventually some light rain will spread into those areas by afternoon and evening but it will remain dry elsewhere. Highs for most 23 to 27 C, but only 15 to 18 C in parts of the north.
TONIGHT the cloud and light rain will gradually spread as far south as some central counties and may become briefly moderate to heavy in parts of Leinster. Winds will swing around to the north and increase to 30-50 km/hr. Lows 10 to 13 C.
WEDNESDAY will be noticeably cooler with moderate north to northeast winds 40 to 60 km/hr, passing showers, and highs 12 to 15 C in the north, 16 to 18 C near the south coast.
THURSDAY will see further showers and moderate north to northwest winds at times, lows near 8 C and highs 14 to 18 C.
FRIDAY will bring variable cloud and some outbreaks of light rain, cool with lows near 7 C and highs near 15 C.
The WEEKEND will also be quite chilly in a brisk northerly flow 50 to 70 km/hr, passing showers and lows near 6 C, highs 12 to 16 C.
The guidance for next week diverges into two rather different outcomes, one is a gradual return to more normal temperatures in a southwest wind flow, while another outcome suggested is a renewed easterly with the potential for significant amounts of rain. I had a look at the support for each of these and can't really say I have a strong preference so will be taking a wait and see approach hoping for better guidance unity by tomorrow.
My local weather was mostly cloudy with a few sunny breaks and passing showers that looked rather ominous at times but delivered only small amounts of rain. It was quite cool at 14 C.0 -
Wednesday, 3 June, 2020
Forecasts for Ireland
TRENDS for the week of 3 to 9 June 2020
-- Temperatures will average 1 to 3 deg below normal values.
-- Rainfall will average 50 to 75 per cent of normal, and near normal in parts of Ulster.
-- Sunshine will average 50 to 75 per cent of normal values.
FORECASTS
TODAY will be breezy and cool with a few showers although some places may remain dry. Winds north to northeast 40 to 60 km/hr. Highs near 14 C in the north, 17 C south.
TONIGHT will bring some clear intervals and isolated showers, cool with lows 5 to 8 C.
THURSDAY will be partly cloudy to overcast with showers developing from north to south, moderate northerly winds and cool with highs around 14 C north, 17 C south.
FRIDAY will become quite windy at times and cold with outbreaks of rain heavy at times in Ulster and north Leinster, parts of Connacht. Winds north to northeast 50 to 70 km/hr will add chill to highs only 12 to 15 C.
SATURDAY will also be quite breezy and cool with further outbreaks of light rain, highs near 13 C.
SUNDAY and MONDAY may see some gradual improvements although further light rain is possible in some eastern counties, as milder air begins to filter in from the northeast around decaying low pressure over Britain and the North Sea. This may allow temperatures to creep back up towards 17 C.
The OUTLOOK is generally warmer by middle of next week, although guidance somewhat unreliable given the large scale change now underway, some suggestions that the warm dome of high pressure we were enjoying last week will try to work its way back from the west, which could bring temperatures back into the 20s eventually.
My local weather on Tuesday was partly cloudy and a bit warmer with highs near 17 C. Some showers developed late afternoon and evening. Meanwhile in the Gulf of Mexico, Tropical Storm Cristobal is bringing heavy rainfalls to parts of the Mexican coastline and may linger near the Yucatan for several days before setting out northwards for an eventual landfall in Louisiana around Tuesday 9th.0 -
Thursday, 4 June, 2020
Forecasts for Ireland
The trends in coming days remain similar, quite a bit cooler than recently and somewhat colder than average, with some rain returning but less than the normal amount in most cases. There probably won't be much sunshine until we get past the weekend.
TODAY will become rather cloudy in all areas, with some light rain moving south later, but it won't reach all parts of the south, amounts where rain does arrive 2-5 mm. Rather cool with highs 14 to 17 C. There will be moderate northwest to north winds 30 to 50 km/hr, sometimes higher gusts near exposed coasts.
TONIGHT will be partly to mostly cloudy with a few showers, moderate northerly winds, and lows near 7 or 8 C.
FRIDAY will be breezy and cool with occasional rain, more persistent in the north where 5-10 mm could fall, 2-5 mm further south. Highs will only reach about 13 C north, to 17 C south. Winds north to northwest 40 to 60 km/hr.
SATURDAY will be quite raw and unpleasant in some parts of the north, and not that much better in the south although if you have higher terrain to your north, you may be somewhat protected from the worst of this briefly strong northerly flow around low pressure over in eastern Britain. Winds could increase to 50-70 km/hr for many areas and 60-90 km/hr in exposed coastal locations. There will be a fairly steady light to moderate rain in some places, trending to occasional showers near the drier south coast. And it will be unseasonably cool with highs only 11 to 15 C from north to south.
SUNDAY will be a turnaround day with improvements to mostly cloudy with sunny breaks, and only isolated showers, also much less windy, so quite a bit more pleasant for outdoor activities with highs 15 to 18 C.
MONDAY and TUESDAY will see some influence from the departed high pressure system that will be trying to make a comeback from a distant westerly location, but it won't succeed in pushing all the way back before another weak set of northerly flow patterns gets into a battle with this high, results being a rather mixed bag of weather that averages close to mid-June normal values, some days a bit warmer near 20 C, other days closer to 15 C. Timing this all out seems pointless with the guidance being only approximate after seven days, but there could be some cooler days again by the weekend of 13th-14th.
My local weather on Wednesday was sunny with cloudy intervals, and it remained rather cool with the high around 17 C at mid-afternoon.
Tropical Storm Cristobal is forecast to linger near the western Yucatan coastline in Mexico, for another day or so, then will be dragged out of that area by a southerly flow that pushes it across the Gulf of Mexico towards western Louisiana where it may arrive by Monday night. It is not forecast to become a hurricane at any point but that remains a slight possibility.0 -

Friday, 5 June, 2020
Forecasts for Ireland
TRENDS for the week of 5 to 11 June, 2020
-- Temperatures will average 1 to 3 deg below normal, with a colder interval at first, a little warmer than average by end of the seven days.
-- Rainfall will average near normal in Ulster and north Connacht, north Leinster, progressively less than normal to 25% on south coast.
-- Sunshine will average 50 to 75 per cent of normal and most of that will begin to show up by Tuesday or so, rather cloudy until then.
FORECASTS
TODAY will be breezy and cool with passing showers, more frequent in the north, in moderate northwest winds 40 to 60 km/hr, increasing later in the day in exposed coastal areas to 50 to 80 km/hr. Rather overcast in general but with a few breaks across southern counties at times. Highs near 14 C north to 17 C south.
TONIGHT will become windy and wet especially in Ulster where 10-15 mm rain could fall. Winds northwest to north 50 to 80 km/hr will make it feel quite raw although temperatures will only drop a few degrees to about 8 C.
SATURDAY will continue very unsettled, especially for the northern half and the morning to mid-day hours. Quite strong and blustery northwest to north winds 60 to 90 km/hr (possibly higher gusts in some exposed areas) and persistent rain, heavier in the north, will make it an unpleasant day in general, and quite chilly with temperatures steady 10 to 12 C north, 12 to 15 C south. It may begin to improve slightly by the late afternoon and evening hours.
SUNDAY will remain rather cloudy but much less windy and dry in most places, still rather chilly, morning lows 6 to 8 C and afternoon highs about 15 to 18 C.
MONDAY will be cloudy with a few sunny breaks, a bit warmer too, lows near 7 C and highs near 19 C.
TUESDAY will be partly cloudy with highs near 20 C. There could be some light showers at times in the north by evening.
The OUTLOOK calls for a steady warming trend after that, with some possibility of very warm weather returning around mid-June for a few days. This warmer spell will not be all blazing sun and dry weather as the flow is somewhat more humid than the May warm spell and bringing along some unsettled pockets in a flow from central Europe, but in general there may be about a week of above normal temperatures coming along by the second week of the outlook period.
My local weather on Thursday was quite pleasant, despite a lot of cloud and some of it occasionally dark and threatening, also patches of blue sky and a warm sun at times, highs near 23 C. It felt more humid than it often does in this region. Meanwhile, Cristobal, reduced to a depression as it wandered inland over the Yucatan, is still expected to redevelop as a tropical storm again over the Gulf of Mexico and move across that over the weekend to strike the Louisiana coast by Monday. It looks like a rain event more than any damaging winds.0 -
Saturday, 6 June, 2020
Forecasts for Ireland
TRENDS for the week of 6 to 12 June, 2020
-- Temperatures will average near or slightly below normal values.
-- Rainfall will average about half of normal values, although near normal for Ulster.
-- Sunshine will average 50 to 75 per cent of normal values.
FORECASTS
TODAY will be quite breezy and cool with passing showers or intervals of light rain, somewhat more persistent in Ulster and north Leinster, with several waves coming through. The southwest and south coast will see the least rain and could get some occasional sunshine. Highs will range from about 12 or 13 C in Ulster to 15 or 16 C on the south coast. Winds northwest 50 to 80 km/hr will be quite blustery in coastal areas and on higher ground.
TONIGHT will bring slow improvement with reduced wind speeds and less frequent showers, but it will likely remain overcast, with lows around 8 C.
SUNDAY will be cloudy with a few brighter intervals developing, still one or two isolated showers possible, but generally dry. Highs 16 to 19 C.
MONDAY will be partly cloudy with lows near 7 C and highs near 19 C.
TUESDAY will bring some sunny breaks to the east, mostly overcast in the west with an interval of light rain likely by afternoon and evening, only about 2-4 mm accumulation expected. Highs near 20 C except 16 C on the west coast.
WEDNESDAY will see some residual cloud and drizzle from the weak front in the west, then a slow clearing trend, highs 15 to 19 C.
THURSDAY and FRIDAY may be somewhat warmer in a southerly flow that will be partly cloudy with some chance of showers, highs 18 to 22 C.
The OUTLOOK continues to be fairly warm but only slightly above average with highs around 20 to 23 C most likely by mid-month. One or two days could be as warm as the mid 20s.
My local weather on Friday was overcast with spits of light rain but no real accumulation yet, as a sprawling low pressure system is deepening over the mountains to our east and drawing in a lot of moisture to create a heavy rainfall situation in Montana and southern Alberta. We are expecting a more moderate amount of rain locally over the weekend. Meanwhile T.S. Cristobal has re-emerged into the Gulf of Mexico and is moving steadily towards a landfall between New Orleans and Houston on Monday morning. This still looks like a rainfall event mainly, and the storm will track well north into the Midwest U.S. where it will merge with some parts of the low I was mentioning over the Rockies -- the cold front from that will be near remnants of Cristobal by Tuesday night and this may produce heavy rainfalls in Iowa and Wisconsin.0 -
Sunday, 7 June, 2020
Forecasts for Ireland
TRENDS for the week of 7 to 13 June 2020
-- Temperatures will average near normal values.
-- Rainfall will average 25 per cent of normal.
-- Sunshine will average 75 to 100 per cent of normal.
FORECASTS
TODAY will be cloudy with some sunny intervals developing, mostly in western and northwestern counties, but a few brighter intervals can be expected in most other parts, and it will be mainly dry with just patchy drizzle in a few spots this morning. Highs 17 to 20 C.
TONIGHT will be partly cloudy and rather cool with fog patches and lows 5 to 8 C.
MONDAY will be partly cloudy to sunny at times, with highs near 20 C.
TUESDAY will bring some increase in cloud especially near Atlantic coasts where rain will develop by afternoon and evening, 3 to 5 mm expected with a rather weak frontal band. It may stay dry further east however. Lows near 7 C then highs 18 to 20 C.
WEDNESDAY will see this weak front moving very slowly southeast, bringing some drizzle along to eastern and southern counties. Amounts will be slight but it could be a rather persistent light rain before slow clearing sets in. Rather chilly as a result, highs 15 to 17 C.
THURSDAY and FRIDAY are expected to be partly cloudy with isolated showers, highs near 18 C.
The further outlook is starting to deteriorate from some earlier projections. There are hints that the flow will turn more easterly, but not with very much warmth associated, then disturbances will begin to rotate around a persistent upper low in the Biscay region. This could bring considerable rainfall to parts of Ireland about ten days to two weeks from now. Temperatures would likely be in a rather narrow range near normal but without much difference from day to night (15-18 C range).
My local weather on Saturday was mostly cloudy with occasional light showers, heavier rain fell in many areas to the north and east as a large low has formed over Montana and southern Alberta. Meanwhile Tropical Storm Cristobal is heading for a landfall in central Louisiana by late tonight and will bring rainfalls of 100-200 mm to the region, then will move quite a long way north as a depression, merging with the cold front of the Alberta low over the Midwestern U.S. by Tuesday.0 -
Monday, 8 June, 2020
Forecasts for Ireland
TRENDS for the week of 8 to 14 June, 2020
-- Temperatures will average near normal values.
-- Rainfall will average 25 per cent of normal.
-- Sunshine will average 75 to 100 per cent of normal.
FORECASTS
TODAY will bring sunny intervals to Leinster and Munster, more cloud than sun in Connacht and Ulster. Some light showers may develop in cloudy areas near Donegal Bay and across west Ulster and north Connacht. Highs 18 to 20 C.
TONIGHT will be partly cloudy to overcast with drizzle near Atlantic coasts, lows 8 to 10 C.
TUESDAY will be mostly cloudy except for parts of the east which will start sunny with increasing cloud by mid-day. Highs 17 to 21 C. Some light rain at times near Atlantic coasts by afternoon.
WEDNESDAY will be cloudy with a few brighter intervals and rather cool with some outbreaks of light rain as winds turn northerly. Lows near 8 C and highs 14 to 16 C.
THURSDAY and FRIDAY will be partly cloudy and slightly warmer with isolated showers both days, lows near 9 C and highs near 17 C.
The WEEKEND (13th-14th) is likely to be similar, partly cloudy to overcast, with isolated showers, highs near 18 C.
The trend in the OUTLOOK is cloudy with occasional rain at several intervals next week, and near normal temperatures.
My local weather on Sunday was mostly cloudy and cool with highs near 16 C. Cristobal has moved inland over Louisiana and will set up some heavy rainfalls in the central states today and Tuesday.0 -
Tuesday, 9 June, 2020
Forecasts for Ireland
TRENDS for the week of 9 to 15 June, 2020
-- Temperatures will average near normal values.
-- Rainfall will average 75 to 100 per cent of normal.
-- Sunshine will average only 50 per cent of normal values, quite a cloudy outlook developing.
FORECASTS
TODAY will be mostly cloudy with a few brighter intervals mainly near east and south coasts. Light rain or drizzle will develop late in the day in western counties and parts of the north. Highs 14 to 17 C.
TONIGHT will be overcast with occasional drizzle or light rain. Lows 9 to 11 C.
WEDNESDAY will be mostly cloudy with showers, and isolated thunderstorms. About 5 to 10 mm of rain is possible in many areas. Highs will be only 12 to 15 C.
THURSDAY will be partly cloudy with isolated showers, slight risk of a heavier thundery shower in a few places. Lows near 8 C and highs 15 to 18 C.
FRIDAY will be mostly cloudy with more widespread outbreaks of rain expected, 10 to 15 mm potential. Lows near 8 C and highs near 17 C.
The WEEKEND will continue rather unsettled with easterly winds and some rain at times, rather cool with highs only 15 to 17 C.
The guidance is trending more unsettled for the following week too, and there could be a gradual return to more normal soil moisture levels as rain, while not all that heavy, may be fairly persistent with a little expected each day, slowly cutting into the dry conditions.
My local weather on Monday was overcast and chilly with thunderstorms that dropped some hail briefly during the afternoon. Highs only around 15 C.0 -

Wednesday, 10 June, 2020
Forecasts for Ireland
TRENDS for the week of 10 to 16 June, 2020
-- Temperatures will average near normal to 1.0 deg above normal values, with a slow rising trend.
-- Rainfalls will average near normal and could be as much as 25-50 per cent above normal in a few locations (midlands most likely).
-- Sunshine will average 50 to 75 per cent of normal values, a rather cloudy scenario in general, with gradual improvement.
FORECASTS
TODAY will be mostly cloudy with a few sunny breaks this morning. Showers will become more widespread after mid-day and there may be some locally heavy and thundery showers in the midlands. Winds rather variable becoming northwest then north 40 km/hr, northeast by the overnight. Highs only 14 or 15 C.
TONIGHT will see further showers and gusty north to northeast winds, lows about 7 C.
THURSDAY will bring a gradual clearing trend in rather blustery northeast winds 40 to 60 km/hr. Showers will become more confined to the south coastal counties before that area also sees some late clearing. Highs 15 to 17 C.
FRIDAY will be rather humid with an increase in cloudiness to fully overcast then intervals of rain are likely to spread through the south and midlands reaching the west and inland north late in the day. Some parts of the east may not see much rain but a few places inland/south could see 10 to 15 mm. Lows near 10 C and highs near 18 C.
SATURDAY will bring a few more showers and a slight risk of a thunderstorm, lows near 11 C and highs near 19 C.
SUNDAY will become partly cloudy with isolated showers and risk of a thunderstorm, lows near 11 C and highs 19 to 21 C.
MONDAY and TUESDAY of next week are likely to be somewhat more settled and quite warm at 22 C.
The OUTLOOK then calls for more showers and outbreaks of rain that could eventually become rather heavy later in the week and into the following week towards the end of June. At this point I am feeling more optimistic that any drought conditions will be easing to at least normal soil moisture by late this month but now the problem could swing towards excess moisture in some cases.
My local weather on Tuesday was overcast with occasional rain and rather chilly with highs only about 14 C. The remnants of Cristobal have moved into Wisconsin and Iowa where a general 25-50 mm rainfall has resulted. Further east it's quite warm although not much above the mid-June normals in a southerly flow. Heavy storms have hit some parts of the plains states and Canadian prairies and some parts of Montana near the centre of low pressure had a heavy wet snowfall during the past day or so with higher areas covered with 20-40 cm but nothing like that happened locally here, our mountains aren't quite high enough to get up into the freezing levels at present time.0 -
Thursday, 11 June, 2020
Forecasts for Ireland
TRENDS for the week of 11 to 17 June, 2020
-- Temperatures will average 1 to 2 deg above normal with a slow increase generally.
-- Rainfall will average 75 to 125 per cent of normal, the south is somewhat more likely to see higher amounts.
-- Sunshine will average 50 to 75 per cent of normal, which means 3-4 hours a day rather than 5 to 5.5 as is typical for mid-June.
FORECASTS
TODAY will see most of the country dry for most of the time, except near the south coast where the remnants of overnight rain will linger a few more hours. There could be isolated showers later in a generally cloudy regime with moderate northeast winds of 40 to 60 km/hr. Any sunshine is most likely to come near the northwest coasts after this cloudy flow gets some drying influences from crossing higher terrain in Ulster and Connacht. Highs 16 to 18 C.
TONIGHT will bring some rain mostly after midnight heading west across the Irish Sea and likely more active for central and north Leinster into the midlands than other areas. About 3 to 6 mm is possible there. Not as breezy with lows 10 to 12 C.
FRIDAY will become a bit warmer once this morning rainfall dissipates, and there could be some brief sunny spells, with a second area of rainfall heading into the southeast towards evening. Highs 17 to 19 C.
SATURDAY morning may be quite wet again as the rain across the south could stall for several hours into the mid-day period before it fragments to a few showers. Amounts further north may be much less than the 10-15 mm expected in the south. Rather warm with lows around 12 C and highs around 20 C.
SUNDAY will be warm and humid with partly cloudy skies yielding to scattered heavy showers and a few thunderstorms. Lows near 13 C and highs near 21 C.
The rather subdued warmth (21-23 C), generally high humidity and occasional rain will remain in place next week although one or two days could be generally dry before a trend begins to more frequent and heavier rainfall accompanied by lower temperatures that will drop a bit below late June average values (in the 16 to 19 C range). Overall it seems that the recent dry spell (or drought for some parts of the south especially) may be in the process of easing to at least normal soil moisture levels towards the end of June.
My local weather on Wednesday was mostly cloudy with scattered light showers around, not much accumulation anywhere from those, and highs near 17 C. We took a drive into the local mountains and found that north slopes of higher peaks (which are around 2200 m) are still snow covered, other slopes are generally snow free now. At pass levels of about 1500 metres, the spring blooming seems to be very slow, with no sign of alpine flowers, and the deciduous trees have not quite formed full leaves yet (we had that look about a month ago at our elevation).0 -
Friday, 12 June, 2020
Forecasts for Ireland
TRENDS for the week of 12 to 18 June 2020
-- Temperatures will average 1.5 to 2.5 deg above normal values.
-- Rainfall will average near normal but with wide variations due to the showery nature of expected rainfalls.
-- Sunshine will average 75 to 100 per cent of normal, provided it becomes more settled late in the interval as predicted.
FORECASTS
TODAY will be cloudy with a few sunny breaks, with moderate easterly breezes at times (30-50 km/hr). There will be a few areas of remnant showery rain this morning but a trend to more settled conditions mid-day and afternoon. Highs 16 to 19 C.
TONIGHT some heavy thundery showers are likely to move into the southeast and across south-central counties. There will be some extension of the rainfall by morning into central counties, amounts will vary from 15-25 mm in a few spots inland south, to 5 mm central. It may remain dry in parts of the north with separate areas of light rain in Ulster. Lows 10 to 13 C.
SATURDAY during the morning the southern showers and isolated thunderstorms will begin to become more isolated although drifting further west in general, then the afternoon and evening will become somewhat more settled with only widely scattered showers. It will be warm and humid with highs 17 to 21 C, warmest values likely to be found in parts of the midlands and western coastal districts.
SUNDAY will also be warm and humid, somewhat unsettled with outbreaks of heavy and possibly thundery showers, most likely over south-central counties. Rainfalls will be quite variable from the showery nature of this activity but could reach 20 mm locally. Lows near 12 C and highs 18 to 22 C.
From Monday to Thursday of next week, a very gradual drying trend is likely in a rather warm pattern with light winds generally, leading to some fog or mist at night, mixtures of cloud and sunshine in the daytimes, with shower activity becoming increasingly confined to a few locations each day. Some places will probably have a generally dry interval. Highs will typically reach 20 to 23 C but could make 25 C in a few parts of the inland south and west, midlands and inland central Leinster. Nights will be fairly mild at 10-14 C. From about Friday 19th on, a more unsettled trend will develop and temperatures will drop back into a more normal late June range, 18 to 21 C with some days perhaps a bit cooler than that.
My local weather was overcast with a few breaks late in the afternoon, and passing showers. Much warmer air has moved in aloft but the effects on surface temperatures were modest, with a high near 19 C. Went up into some higher country east of here around mid-day and saw a grizzly bear (black bears are more commonly seen) beside the road. It was not in attack mode but quite a sight (I have seen one or two from a greater distance before). There was still a lot of snow around just above where the grizzly was spotted (probably just woke up) and the car thermometer dropped off to 8 degrees as we climbed to about 1600 metres above sea level. From there on up to peak levels in that area, heavy snow was still present on all slopes. Summer doesn't really come until the middle of July in the alpine.0 -
Saturday, 13 June, 2020
Forecasts for Ireland
TRENDS for the week of 13 to 19 June 2020
-- Temperatures will average about 2 deg above normal.
-- Rainfall will average near normal to 25 per cent above in some western counties.
-- Sunshine will average near normal, although the latter part of this interval will have to exceed normal to bring that about.
FORECASTS
TODAY will be cloudy with a few sunny breaks. Scattered light rain this morning will gradually die out for a while, then heavier and possibly thundery showers will develop in the inland south, spreading to some parts of the western counties. Showers will be more isolated in Leinster and Ulster as well as eastern Connacht. Some heavy downpours are possible especially around the Cork-Kerry border regions. Highs 17 to 20 C.
TONIGHT will become misty with showers mostly dying out, lows near 12 C.
SUNDAY will be rather warm and humid with partly to mostly cloudy skies in the morning, leading to outbreaks of heavy thundery rain across large parts of the midlands, inland south and west. Galway may be particularly at risk of localized flooding. 20 to 40 mm of rain are possible in some of those areas. Highs 17 to 21 C.
MONDAY will be partly cloudy with showers much less widespread, probably isolated to a few parts of the inland southwest. Lows near 13 C and highs near 22 C.
TUESDAY will be hazy and warm with isolated showers, lows near 13 C and highs near 23 C.
Later in the week, somewhat less humid but continued rather warm, temperatures could drop a degree or two but it will still be feeling rather warm for mid-June, highs 20 to 22 C.
The relatively settled weather expected most of next week will begin to break down around the weekend of 20th-21st, but some guidance is trending drier now and pushing that breakdown back into the week following. All guidance does agree that there could be quite an unsettled interval late in the month.
My local weather on Friday was warm and humid, thunderstorms in the early morning hours cleared north and stayed away until showing some signs of redeveloping later tonight here (currently 11:30 p.m. in my time zone). Highs reached about 23 C.0 -

Forecasts for Ireland
TRENDS for the week of 14 to 20 June 2020
-- Temperatures will average about 1 deg above normal values.
-- Rainfall will average near normal to 25 per cent above normal in parts of the west.
-- Sunshine will average 75 to 100 per cent of normal values.
FORECASTS
TODAY will be mostly cloudy with a few brighter intervals more frequent near the south coast and in northern counties. Heavy and at times thundery showers will develop across the southeast and spread to most central and western counties by mid-day. Some heavy falls are expected especially around the midlands to Galway, local flooding may develop with potential for 15-30 mm falls. Northern counties will see more isolated outbreaks but some could be heavy there also. Highs 16 to 19 C.
TONIGHT will be foggy or misty with the shower activity dying out, lows near 12 C.
MONDAY will see a somewhat less active replay of today's scenario with perhaps longer sunny spells in the mix, still some potential for localized heavy downpours, inland southwest favoured. Highs 17 to 21 C.
TUESDAY will also be unsettled with possibly an early morning outbreak for Leinster spreading across into west-central counties during the later morning hours. Some sunny spells will develop, warm and humid with lows near 13 and highs near 21 C.
WEDNESDAY will be more settled with fog in the morning giving way to some hazy sunshine and just isolated showers or thunderstorms, highs near 20 C.
THURSDAY and FRIDAY look fairly pleasant with sunny breaks and some cloudy intervals, isolated showers, highs near 19 C.
The weather pattern will become more mobile westerly after that with some rather strong frontal systems (for late June) and possibly a few rather wet days towards the end of the month, with temperatures only around 17 or 18 C.
My local weather on Saturday was overcast and rather foggy at times with a few outbreaks of light rain, and highs near 16 C.0 -
Monday, 15 June, 2020
Forecasts for Ireland
TRENDS for the week of 15 to 21 June, 2020
-- Temperatures will average 1 to 2 deg above normal values.
-- Rainfall will average about half to 75 per cent of normal, locally closer to normal in isolated heavy showers.
-- Sunshine will average near normal values (about 5 hours a day at this time of year).
FORECASTS
TODAY will start out sunny and warm in many areas. Some isolated heavy showers and thunderstorms will develop in parts of the midlands, inland north and these will track west towards the Atlantic coast. There will be some chance of outbreaks in all areas eventually but the heaviest are likely to be in similar locations to Sunday, or perhaps a little further south. Highs 20 to 24 C.
TONIGHT will become mainly clear and dry with fog or mist patches, lows near 13 C.
TUESDAY will bring another round of scattered heavy showers and thunderstorms, highs 20 to 23 C.
WEDNESDAY will be somewhat cooler with the shower activity more confined to Leinster, lows near 11 C and highs around 21 C.
THURSDAY may be largely dry with sunny intervals and highs near 20 C. There will be isolated showers in the north.
FRIDAY will see partly cloudy skies and isolated showers, highs near 21 C.
SATURDAY will bring increasing cloud, with risk of showers and thunderstorms later in the day from the west, highs around 22 C.
SUNDAY will be partly cloudy with isolated showers, highs near 20 C.
The OUTLOOK for the following week now involves a split in guidance, with some emphasis on a warm, dry and settled interval but different evolutions about how long that might last before breaking down into occasional thundery rainfall events mid to late week (by then near the end of June). Temperatures could peak at some point by mid-week near 25 C before dropping back into the lower 20s.
My local weather on Sunday was mostly cloudy with passing showers and quite cool, only around 13 C.0 -
Tuesday, 16 June, 2020
Forecasts for Ireland
TRENDS for the week of 16 to 22 June, 2020
-- Temperatures will average 1 to 2 deg above normal values.
-- Rainfall will average 25 per cent below normal in some parts of the west to 75 per cent above normal values with Leinster now more likely to see highest amounts.
-- Sunshine will average about 75 per cent of normal but could be rather variable from one location to another depending on persistence of showers.
FORECASTS
TODAY will start out rather misty and locally foggy, with sunshine developing later on. There could be a few scattered showers in the morning, but heavier showers and thunderstorms will develop in eastern and central counties by afternoon, persisting well into the evening once formed. Central Leinster from Dublin west into Kildare and west Wicklow, Laois and Carlow may see some of the heavier activity today, with some of that spreading into nearby portions of other counties. Another cluster is likely to form further west. Higher terrain may anchor the development of these storms but once formed they could drift away from where they form in a generally southwesterly direction towards Cork and Waterford. Some heavy amounts (20-40 mm) and local stream flooding are possible. Highs today will reach 21 or 22 C in sunny spells but temperatures could drop into the 15-17 C range during prolonged rain.
TONIGHT will see these thundery showers slowly dissipating, followed by extensive fog and mist with clear skies further west in any areas that escaped rainfall earlier. Lows 10 to 13 C.
WEDNESDAY will be somewhat of a repeat performance with another round of heavy showers and thunderstorms in eastern counties, partly cloudy skies expected for the west and north, highs 19 to 21 C.
THURSDAY will be partly cloudy with isolated showers and thunderstorms, and some outbreaks of heavier rain now expected to move into the southeast by evening. Lows near 10 C and highs near 20 C.
FRIDAY will be partly cloudy with morning outbreaks of showery rainfall spreading northwest then clearing, lows around 9 C and highs around 19 C.
SATURDAY will become breezy and there could be some outbreaks of heavy rain in places as a frontal system pushes into this disturbed air mass from the Atlantic. Lows near 12 C and highs near 18 C. Winds southwest 40 to 70 km/hr may become gusty at times.
SUNDAY will continue rather unsettled with some improvements spreading in from the west, highs near 19 C.
Next week still has that uncertain evolution attached, with a warmer air mass spreading into parts of Britain but possibly an active frontal zone developing by mid-week through Ireland, leading to possible heavy showers and thunderstorms again. Temperatures may reach the lower 20s.
My local weather stayed cool and overcast with occasional light showers, highs near 15 C.0 -
Wednesday, 17 June, 2020
Forecasts for Ireland
TRENDS for the week of 17 to 23 June, 2020
-- Temperatures will average about 1.5 deg above normal values, nights will be more above average than days.
-- Rainfall will average between 125 and 250 per cent of normal values and could exceed that range in a few places.
-- Sunshine will average 50 to 75 per cent of normal values.
TODAY will bring outbreaks of heavy rain to Leinster, and while not expected to be continuous, there may be several intervals of rain with brief brighter intervals between them. Later in the day the showers will be more likely to turn thundery but heavy downpours are possible before that. Spot flooding may develop as the heavy rain falls over higher terrain south of Dublin. Readers in that area are advised to monitor all official alerts and be ready to take precautions. There is potential for 20-40 mm amounts both today and tomorrow which could lead to localized severe flooding. The spread of heavy showers towards central counties will be gradual but some could spill as far west as the midlands at times. Near the west coast it is more likely to remain dry with some longer sunny breaks possible once the low cloud or fog dissipates later this morning. Warm and muggy with highs 19 to 23 C.
TONIGHT could see the heavy showers continuing somewhat further inland from the east coast, with 10-20 mm amounts added in some places. Lows 11 to 14 C.
THURSDAY expect an outbreak of heavy rain with thunder and possible hail from Leinster into the midlands and eventually working further northwest into Connacht. Amounts of 20-40 mm are possible. Not much if any sunshine is expected except possibly in coastal south Cork and Kerry and some parts of Ulster. Highs 17 to 20 C.
FRIDAY will see a bit of a break between this current disturbance and a frontal system forming out in the Atlantic, but there may still be some showers around. There could also be some longer sunny breaks with highs 17 to 20 C.
SATURDAY will turn quite windy and will become wet from west to east during the day, 20-30 mm of rain is possible especially in Munster and parts of south Connacht. Winds south to southwest 50 to 70 km/hr and temperatures fairly steady in the 15 to 18 C range.
SUNDAY will be blustery and somewhat fresher with passing showers or outbreaks of light rain, winds southwest to west 40 to 70 km/hr, highs near 17 C.
NEXT WEEK will try to warm up but most of that warmer air will be confined to the southeast and parts of Britain before a number of disturbances take a run at Ireland from the west, with more briefly heavy rainfalls quite likely during the middle of the week.
My local weather on Tuesday was sunny with cloudy intervals, threatening looking clouds around but no rain fell from them, highs around 19 C.
Would advise if you're in central Leinster, check in with the boards thunderstorm discussion for updates and observations; I may post an update if I see anything of concern but in any case stay alert for the possibility of local flooding especially where streams come out of the higher terrain.0 -
Thursday, 18 June, 2020
Forecasts for Ireland
TRENDS for the week of 18 to 24 June, 2020
-- Temperatures will average about 1.5 deg above normal values.
-- Rainfall will average 25 to 50 per cent above normal values.
-- Sunshine will average only 50 to 75 per cent of normal.
FORECASTS
TODAY will be rather cloudy with a few brighter intervals, and it will be generally dry through the morning and in most places also for much of the afternoon. Isolated heavy showers may develop ahead of a more widespread rainfall event overnight. Highs 17 to 20 C.
TONIGHT will see outbreaks of heavy rain, possibly thundery although this aspect seems less likely now. The rain is already falling over much of Britain without much thunder associated there. Heaviest falls will likely be in a convergence zone running from the inland southeast through the midlands towards Galway and eastern Mayo/Sligo. Amounts of 20-30 mm are possible there. Somewhat less is expected on either side of that zone (10-20 mm in most cases). If any thunderstorms do form, even heavier localized amounts are possible and that could intensify any flooding that develops. Foggy after the rain begins, with lows only dropping to about 14 C (a bit lower in west Munster due to some breaks in the overcast expected there).
FRIDAY will find this rainfall quickly fragmenting to showers as the jet stream, having tired of watching this long display of atmospheric blocking over western Europe, sweeps the remnants away to the north and resumes normal service of west to east motion of weather systems. That will involve a dry slot between the overnight rainfall and an advancing strong frontal system for Saturday; skies could become partly cloudy in some parts of the country with a bit of afternoon and evening sunshine as showers become rather isolated. Highs 16 to 19 C.
SATURDAY will become quite blustery and wet as the strong front moves in, with some risk of localized thunderstorms developing in the midlands by late afternoon. Winds southwest 50 to 70 km/hr and even higher gusts possible near Atlantic coasts. Lows near 12 C and highs near 17 C. About 10-20 mm rain expected.
SUNDAY will be brighter, rather breezy and fresh with passing showers, lows near 10 C and highs near 17 C.
MONDAY will bring outbreaks of rain, possibly heavy in some places, and temperatures once again near 17 C.
Later next week, there will be less disturbed weather but still in a southwest to westerly flow off the Atlantic, with partly cloudy skies and brief passing showers from weak troughs or fronts. Temperatures may manage to reach about 20 to 22 C during the sunny breaks expected each day. It could be a bit warmer than that in a few places around the southeast coast and more like 16 to 19 C in much of Connacht and Ulster.
My local weather on Wednesday involved dramatic buildups of small thunderstorm cells, one or two of which dropped rain briefly with a couple of thunderclaps noted off to the south, but there was also some sunshine at times and it was a bit warmer than recent days at 20 C.
If today's scenario (unlike yesterday) proves more active than expected by mid-afternoon, I may issue an update, but at the moment it looks like most if not all of the active weather will arrive in the evening and overnight. That may still require an update by 7-8 p.m. to clarify timing and location of heaviest rainfalls.0 -
Friday, 19 June, 2020
Forecasts for Ireland
TRENDS for the week of 19 to 25 June, 2020]
-- Temperatures will average near normal to 1.0 deg above normal.
-- Rainfall will average near normal except for some higher amounts in Connacht and Ulster.
-- Sunshine will average only about 50 per cent of normal values.
FORECASTS
TODAY ... Rain will become more showery but there could be persistent outbreaks in north Leinster, east Ulster and some parts of Connacht, the midlands and the inland southeast, before a general clearing trend later. Partly cloudy skies will prevail further west with best chances for sunshine around Cork and Limerick. Highs 17 to 19 C.
TONIGHT ... Some clear intervals but widespread fog and mist likely, lows 7 to 10 C.
SATURDAY ... Rain will develop by late morning in the west and will rapidly spread east after a bright start to the day on the east coast. Winds will increase to southerly 50 to 70 km/hr ahead of a front that will sweep in late in the afternoon, with some heavy downpours associated. Rainfalls of 10-20 mm are likely. Highs near 17 C.
SUNDAY ... Partly cloudy, passing showers, breezy with lows near 9 C and highs near 17 C.
MONDAY ... Rain could become heavy at times, lows near 12 C and highs near 17 C.
TUESDAY ... Overcast with showers or periods of rain, lows near 14 C and highs near 16 C.
FURTHER OUTLOOK ... Somewhat improved later in the week with showers more isolated, longer dry spells likely, and temperatures responding to the sunshine by moving up into the low 20s in some parts. Even warmer by the weekend of 27th-28th.

Forecasts for Ireland
TRENDS for the week of 20 to 26 June, 2020
-- Temperatures will average slightly above normal values by 0.5 to 1.5 deg.
-- Rainfall will reach normal values in some parts of the west, but may be as low as 50% in the east.
-- Sunshine will be 50 to 75 per cent of normal values; some improvement will be noted later in the week.
FORECASTS
TODAY will have a dry and bright start in most areas, with any morning sunshine fading behind thickening clouds by mid-day. Rain will sweep into the western counties later this morning to mid-day but will then make rather slow progress east, arriving in Dublin perhaps by late afternoon. The band of rain may contain some strong shower cells and isolated thunderstorms. Becoming quite windy by mid-day west and afternoon east, southeast to south winds of 50 to 80 km/hr with higher gusts possible during the frontal passage as winds veer southwest. Highs 17 to 19 C.
TONIGHT will see the rain tapering off to showers, as moderate southwest winds continue at 40 to 60 km/hr. Lows will drop only to about 12 or 13 C. Total rainfalls for the event will be 15-25 mm. Note: the summer solstice occurs at 10:44 p.m. this evening. See note after forecast.
SUNDAY will become partly cloudy with passing showers, winds southwest 40 to 60 km/hr, highs 17 to 19 C.
MONDAY will be mostly cloudy with occasional light rain and a few heavier showers embedded in Atlantic coastal counties. Amounts of 5-15 mm can be expected. Lows near 13 C and highs near 18 C.
TUESDAY will continue rather cloudy with showers, perhaps more confined to western counties, 3 to 7 mm is expected with this round. Lows near 14 C and highs 16 to 18 C.
Later in the week, it may warm up slightly and values in the low 20s could reach southeast Ireland as very warm air is heading for Britain from a south to southwest direction (25-28 C likely there). Ireland will remain in a transitional zone between fronts and could see a few cloudy spells with isolated showers during this warmer phase. Another active cold front is expected around Saturday 27th somewhat similar to today's event although perhaps not as strong, then a period of near average temperatures in westerly winds is expected as we reach the first of July.
My local weather on Friday was quite warm with sunshine for a while in the morning. High cloud layers spread in but showers remained off to our north. The high was about 24 C.
More info on the summer solstice (at 10:44 p.m. IST) ... Why not the 21st? Leap year added that extra day and reset the schedule, the next three will be at various times on the 21st (IST) almost six hours later each time. These astronomical events occur about 365.24 days apart, which is why we have leap years to keep our calendar in sync with them. We are so used to the solstice being on the 21st that most celebrations or observances will take place on Sunday morning anyway. And the Sunday sunrise will be closer to the solstice than today's sunrise was.0 -
Sunday, 21 June, 2020
Forecasts for Ireland
No changes in the pattern but trends will show a difference as we lose the rainfall from yesterday from the outlook:
TRENDS for the week of 21 to 27 June, 2020
-- Temperatures will average 1 to 2 deg above normal, warmer in the southeast.
-- Rainfall will average near normal in the west, to about 50% of normal in the east.
-- Sunshine will average 75 per cent of normal and could touch 100 per cent in the southeast.
FORECASTS
TODAY will be partly cloudy with passing showers, one or two of them thundery in north central counties and the midlands. Some sunny breaks will develop but cloud will tend to dominate. Highs 17 to 19 C with moderate southwest winds 40 to 60 km/hr.
TONIGHT will be partly cloudy to overcast and quite mild with lows only falling to about 13 or 14 C. Some parts of east Ulster and north Leinster with clearer skies could drop to 8 or 9 C. Generally dry as the daytime showers will dissipate. Some rain by morning in the west however.
MONDAY will see rather persistent rain, heavy at times, in western counties with more of a showery distribution towards central counties and possibly very little falling in the east where some sunny breaks could persist. As a result highs will be closer to 20 C in the east and 17 C in the west. About 10 to 15 mm rain is likely in western counties.
TUESDAY will find the same front stalled out over western counties, some additional rain will fall there although it looks to be rather light (3-7 mm potential) before a slow clearance settles in. The east may remain largely dry with just isolated showers expected. Once again, a rather narrow temperature range from 14 C to 18 C west, 13 C to 20 C in the east.
WEDNESDAY to FRIDAY will be a generally dry interval with a few isolated showers possible each day, in a rather slack southerly gradient where Britain and perhaps some parts of southeast Ireland will get into a warmer air mass that has 25 to 28 C potential, while most of Ireland remains in a transitional zone of 19 to 22 C. Even so, that will feel quite warm as it will be partly cloudy to sunny at times with slack winds and fairly high humidity levels. Nights will remain mild at around 10 to 12 C.
This warmish spell will end with a showery cold front on Saturday 27th with temperatures falling back to the 17-19 C range. The weather after this front will remain rather cool and unsettled for a while, although not far from late June averages.
My local weather on Saturday was overcast with one brief shower and a tepid high of about 18 C. Astronomy note, the new moon is timed for 0742h today so it is just taking place, and will produce an "annular" type solar eclipse in parts of the Middle East so if you read this soon after I post it you might find some live or recent internet coverage of that event. An "annular" eclipse happens when the Moon is distant enough from the earth in its elliptical orbit so that it cannot cover the entire disk of the Sun and so a "ring of fire" persists at totality. (note on the timing, this is always based on a local solar noon alignment and the geometry of eclipses demonstrates that the alignment moves from west to east, in eclipse cases it can take several hours to cross a continent, so the 0742h likely means that the annular eclipse has already happened in some places and not yet in others further east.)
(added at 0830h ...)
This link will explain the eclipse timing and track, by now it has pretty much ended for all but the far eastern portions of the track shown ... add one hour to the link's imagery timing as that appears to be GMT rather than IST.

Forecasts for Ireland
TRENDS for the week of 22 to 28 June, 2020
-- Temperatures will average 1 to 2 deg above normal values.
-- Rainfall will average near normal although with local variations in the range 50-150 per cent.
-- Sunshine will average 75 to 100 per cent of normal values.
FORECASTS
TODAY will continue rather cloudy and there will be further outbreaks of rain, mostly over western counties where about 10-15 mm could accumulate. Highs near 17 C west, 19 or 20 C east. Moderate southerly winds will ease during the afternoon.
TONIGHT will be overcast with light rain or drizzle in some parts of the west-central counties. Lows 12 to 14 C.
TUESDAY will see this weak front trying to edge further east, as it does so it will begin to lose what little moisture and energy it has left, and fragment to scattered light showers. Highs near 18 C.
WEDNESDAY some warmer air will begin to push into the southeast and central counties, but may not quite reach the west or north until late in the day. This will bring temperatures up into the 21-23 C range for many parts of the country with slightly lower values around the coasts. A few scattered showers could develop but not much rain is expected.
THURSDAY will be warm and humid with lows near 12 C and highs near 24 C. There could be a few isolated showers or thunderstorms. By Thursday night there could be an outbreak of heavier storms in the southeast.
FRIDAY will be warm and humid with thunderstorms possibly heavy in Leinster. Lows near 14 C and highs 22 to 25 C.
SATURDAY will become cooler with southwest winds and isolated showers, as a front pushes the warmer air east during the early morning hours. Lows near 16 C and highs near 20 C.
SUNDAY will be partly cloudy, cooler with isolated showers, highs near 18 C.
The trend for the following week will take temperatures a little below average at first, then return them to near normal later, with small amounts of rain in weak frontal passages in an Atlantic-driven westerly flow. The average high for the week will likely be around 19 or 20 C.

-- Sunshine will average 75 per cent of normal values.
FORECASTS
TODAY will be mostly cloudy with rather persistent light rain in many areas, more showery in the southeast, and sometimes dry in the far northwest, as the front stalls out across the midlands. About 10-15 mm further rainfall is possible. Highs 16 to 18 C.
TONIGHT the rain will taper off to drizzle and fog, with lows only falling slightly to 13 C.
WEDNESDAY will become partly cloudy and quite warm in most areas, slightly cooler near Atlantic coasts, but generally highs will reach 22 to 25 C. There could be isolated showers by afternoon in north-central counties.
THURSDAY will be partly cloudy with isolated showers turning thundery late in the day with a fairly significant outbreak possible by evening. Lows near 15 C and highs 22 to 25 C.
FRIDAY will see the thundery showers moving north into Ulster by afternoon, with partial clearing to follow, lows near 17 C and highs near 22 C.
SATURDAY will be cloudy with a few breaks, and showers may be briefly heavy, lows near 14 C and highs near 20 C.
SUNDAY will turn cooler with more showers and moderate westerly winds, lows near 10 C and highs near 17 C.
The outlook for the following week into early July is rather unsettled with temperatures near average for time of year, which would be around 20 or 21 C by day.
My local weather on Monday was sunny all day for the first time in quite a while, and very warm with highs reaching at least 25 C (probably closer to 30 at valley elevations).0 -

TRENDS for the week of 24 to 30 June 2020
-- Temperatures will average 2 to 3 deg above normal values.
-- Rainfall will average near normal to 25% above normal.
-- Sunshine will average only 50 to 75 per cent of normal (which is currently about 6 hours a day).
FORECASTS
TODAY will see the last of the persistent rain more confined to central Ulster before ending entirely, and skies will become partly cloudy with warm sunny spells in some areas. Isolated showers could redevelop over the inland south by late afternoon. Highs 21 to 24 C. Rather humid, feeling quite muggy.
TONIGHT will be rather muggy also with lows around 14 C and some mist or fog patches.
THURSDAY will start out with some warm sunny spells but cloud will gradually increase, followed by outbreaks of showers that may turn thundery by late afternoon and evening. Warm and humid with highs 22 to 25 C.
FRIDAY will see thunderstorms moving north and spreading into Ulster, with partial clearance to follow for most other areas, but another batch of thundery showers could spread into the south by late in the day. Lows near 15 C and highs 21 to 23 C. Overall rainfalls from all these passing showers may vary from 5 to 20 mm with higher amounts for central and inland southern districts.
SATURDAY will become a bit cooler with scattered showers and moderate southwest to west winds, lows near 12 C and highs near 19 C.
SUNDAY will be quite cool with occasional showers, some clearing later in the day, lows near 9 C and highs near 16 C.
MONDAY and TUESDAY may bring another rainfall of about 10-15 mm.
The OUTLOOK moving into July is for a rather cool and unsettled start to the month, but signs of a considerably warmer interval developing by about the 10th possibly persisting into mid-month.
My local weather was rather dramatic for a change. We started out with hot sunshine, then had increasing cloud in the afternoon, with a high near 29 C. A strong thunderstorm formed over the hills west of us and moved across the town with small hail and very gusty winds at times, probably at least 20 mm of rain in an hour or less.
A fourth tropical storm has formed in the Atlantic (Dolly) but is quite weak and no big threat to land, other than some rain and moderate winds for eastern Newfoundland.0 -
Thursday, 25 June, 2020
Forecasts for Ireland
TRENDS for the week of 25 June to 1st of July, 2020
-- Temperatures will average 1 to 2 deg above normal but much of that due to very warm readings today.
-- Rainfall will average near normal values but could exceed normal in parts of west Ulster and the inland southeast.
-- Sunshine will average 50 to 75 per cent of normal values.
FORECASTS
TODAY will be very warm and muggy with some sunshine despite cloud cover rather extensive, possibly longer sunny spells in parts of midlands and inland southeast. Highs 23 to 27 C for most, near 20 C around some western coasts. Some thundery showers could be developing late in the day but most of the action will be in the overnight period.
TONIGHT some clusters of thunderstorms are quite possible in Leinster and Ulster mainly, although nearby portions of Connacht and Munster are in play also. There could be two main clusters developing, one in the north midlands moving towards Donegal and western NI, and another over the Irish Sea affecting coastal Leinster and moving towards east Ulster. These could form some connections through north Leinster. Other isolated thunderstorms are possible in other parts of Munster and Connacht. Locally heavy downpours of 10-20 mm are possible, and frequent lightning may develop. Strong wind gusts and hail are less likely hazards in this setup. Overnight lows 14 to 17 C.
FRIDAY will see some remnant showers and thunderstorms and some sunny intervals, with little to no wind, still feeling rather warm and muggy, highs 20 to 23 C. Another round of heavy showers and thunderstorms is possible across the inland south by late afternoon, evening and overnight into early Saturday.
SATURDAY will see the overnight showers ending, some partial clearing, then cooler westerly breezes and partly to mostly cloudy skies with scattered showers. Lows 12 to 15 C and highs 17 to 19 C.
SUNDAY will be breezy (westerly 40-60 km/hr) with passing showers, quite cool with lows near 9 C and highs 14 to 17 C.
MONDAY could see rain across parts of the south, scattered or isolated showers further north, still rather cool with lows near 8 C and highs near 16 C.
TUESDAY will become partly cloudy later in the day with showers ending, highs near 17 C.
The general trend beyond that is unsettled and near normal in temperatures (at best, could be a bit cooler).
My local weather on Wednesday was warm and humid (25 C) with thunderstorms rumbling past to the south at 1 p.m. then to the north at 3 p.m., our result here was just a little rain, some gusty winds, and clearing by late afternoon. Some of the storm cells looked severe on radar so probably a good thing they missed our location.
Will take a close look at thunderstorm potential for tonight during the afternoon hours and probably will update the forecast around 5 to 6 p.m. even if no significant changes.0 -
UPDATE _ Thursday, 25 June, 2020 _ 6 p.m. IST
____________________________________________
No significant change to the outlook ... gradual development of showers and thunderstorms is likely to continue this evening and overnight, with peak of activity most probable around 0300h. The most promising storm potential is around the east coast, parts of the midlands and west Ulster, but other isolated cells could develop in other areas.
May post another update towards 11:30 p.m. to midnight.0 -
Friday, 26 June, 2020
Forecasts for Ireland
More of a blog format today ... trends remain similar and consistent with an unsettled, near average temperature pattern with limited sunshine.
Storms moved into parts of the southeast overnight and were reported to be heavy or intense around Gorey, Arklow and as far north as Bray. They appeared to lose energy on approach to the Dublin region around 0400h and there was little left of that cluster by 0600h.
Another more prolonged heavy to severe storm cluster developed over north Connacht and remained mostly over east Mayo, south Sligo and Leitrim. This has begun to move further north and is still quite active with reports of strong thunder and 15-20 mm downpours that could cause some localized flooding in that area, including parts of Donegal and western NI.
That activity is likely to die out gradually by mid-day as well as moving off the land mass towards the Hebrides, so that will leave most areas in a relatively calm, inactive zone between the overnight disturbances and an approaching upper level low that will force more activity to develop across the south later today. Under partly cloudy to overcast skies, highs will reach 21 to 23 C in many places, but may be held to 18 C near some coasts, in particular the southwest coast due to onshore breezes from the west backing to southerly.
This next round may be somewhat more widespread but less intense, so would expect quite a few locations to report showers or thunderstorms later today and overnight, with 5-15 mm rain potential. If there were to be any heavy or severe storm development, that would be more likely for the inland southeast than other areas, but it could top off at just moderate showers and light thunderstorm activity. Lows overnight will be around 12 to 15 C.
Saturday will continue rather unsettled as this upper level low takes a left turn around Cork and starts moving north across the country. This may lead to outbreaks of rain with embedded thundery downpours on Saturday, but also a few brighter intervals mixed in. Highs will be near 17 C. It will begin to get rather breezy in the wake of this disturbance and fronts that will form over Ireland on Saturday.
Sunday will remain breezy and quite cool, with westerly winds reaching 50 to 70 km/hr at times, intervals of rain, and highs only around 15 or 16 C after a morning low near 10 C. The north in particular may have quite an unpleasant day, with slight improvements possible for the south late in the day.
Monday, a weak system will descend from the north and renew the shower activity if it ever comes to an end Sunday night, but mainly in northern counties. A separate weak frontal wave will skim the south coast and increase cloud there and possibly bring in some light rain. Lows will be near 8 C and highs near 16 C.
The weather pattern from Tuesday to about Friday of next week will remain rather unsettled as a large but poorly defined low pressure complex settles in over the region. The most likely outcome will be partly to mostly cloudy skies and occasional showers, isolated thunderstorms, and moderate breezes from various directions as weak troughs and small-scale lows form and circulate around. Highs each day will probably be in the 17 to 19 C range. Nights will be generally around 8 to 11 C.
That pattern may not break down very quickly but if anything the trend into mid-July should be improving somewhat towards more frequent dry and sunny spells but still occasional showery interludes, and temperatures perhaps coming back into the low 20s at times.
My local weather on Thursday was mainly sunny with a few cloudy intervals, and rather warm at 25 C.0 -

The rest of the week will continue unsettled and cool with significant amounts of rain possible around Thursday into Friday again, temperatures staying below normal values with highs only around 15 or 16 C.
A gradual improvement to more average conditions will probably begin in the first full week of July.
My local weather on Friday was overcast but rather warm with highs near 25 C. Expecting considerable amounts of rain this weekend with a sharp cooling trend here also.0 -

Sunday, 28 June, 2020
Forecasts for Ireland
TRENDS for the week of 28 June to 4 July 2020
-- Temperatures will average 2 deg below normal values.
-- Rainfall will average about 50 per cent above normal values in the west and north, closer to normal south and east.
-- Sunshine will average 50 to 75 per cent of normal values.
FORECASTS
TODAY will be very windy in northern and west-central counties, and quite breezy elsewhere, winds from the west will average 50 to 80 km/hr with some higher gusts (30 to 50 km/hr in sheltered inland areas). It will be mostly cloudy with a few breaks from time to time across the south mainly. Bands of rain or drizzle will continue to bring some heavier bursts of 10-15 mm rainfall to the north, but some parts of the south could be largely dry. Very cool for late June, highs only 12 or 13 C in the north, to 16 or 17 C in the south.
TONIGHT will see further rain and moderate westerly winds slowly abating, lows near 10 C.
MONDAY will bring variable amounts of cloud, and more isolated showers, mainly in two areas, the far north, and the southwest coast by afternoon. Some areas in between could be dry but there will be isolated showers in all regions. Highs about 14 to 17 C.
TUESDAY will bring similar weather conditions except for a more organized band of light rain moving into the south later in the day. Otherwise partly cloudy and cool with isolated showers, lows near 8 C and highs near 16 C.
WEDNESDAY will continue unsettled with occasional rain and highs near 16 C.
THURSDAY could turn somewhat warmer with a few sunny breaks in the south, still a threat of rain in the north, and highs near 19 C.
FRIDAY will see strong southwest winds returning with early morning rainfall becoming more showery with isolated thunderstorms possible, highs near 17 C.
The OUTLOOK is for improving conditions through the weekend of the 4th-5th and into the following week, with highs possibly back up into the low 20s at times, and more sunshine than we'll see this week.
My local weather stayed dry until late afternoon then a few showers moved through. The front seemed to be much stronger earlier in the day further north, then "petered out" which works for us, highs around 20 C. We are now into a cooler air mass and Sunday here will be around 17 C. If you watch golf and have any coverage of the Utah golf event on the secondary tour over here, there could be some dramatic skies and weather events there on Sunday afternoon. I may be the only person watching this for the weather rather than the golf later on. The front that went through here will be down that way by Sunday afternoon.
Not a very nice outlook there for the coming week but at least it does not appear to be locking in for weeks.0
