    Forecasts for Ireland



    TODAY ... A few sunny intervals more frequent in south this morning, but a trend to more overcast skies by afternoon, with outbreaks of very light rain mostly confined to Atlantic counties and even there giving only 1-2 mm. Highs about 14 to 17 C from north to south.

    TONIGHT ... Overcast, some rain at times in western counties, becoming somewhat heavier towards morning, fog or mist further east in central counties. Lows 7-10 C.

    FRIDAY ... Periods of rain may become rather heavy across the west during the morning, slowly clearing east, then an interval of moderate rain will develop late in the day for eastern counties. Amounts 5-15 mm with the heavier falls inland west. Afternoon highs 16-18 C.

    SATURDAY ... Partly cloudy with just a few isolated showers near northern and some western coastlines, increasingly humid, lows 7-9 C and highs 16-18 C.

    SUNDAY ... Periods of rain will develop during the morning in the south and west, spreading to the north and east by afternoon or evening, in strong southerly winds 50-80 km/hr with the risk of higher gusts near exposed south and west coasts. About 20-30 mm of rain may fall during this storm which will persist into early Monday (with a second interval of rain likely by Monday night and Tuesday). Temperatures steady 15-17 C.

    MONDAY ... Gradual clearing for at least part of the day, except for some areas of rain persisting in north Connacht and Ulster, still quite windy (southwest 50-80 km/hr). Further showers or periods of rain will develop towards late afternoon or evening in western counties. Lows near 13 C and highs near 17 C. About 10 mm of rain is expected by early Tuesday in some western counties.

    TUESDAY and WEDNESDAY will probably see the slowly decaying phases of the storm with more moderate southwest winds 40-60 km/hr and occasional rain, temperatures in a rather narrow range 12-17 C. There may be an interval of heavier rain again by late Wednesday into early Thursday from a new disturbance forming in the wake of the earlier storm.

    FURTHER OUTLOOK calls for slight improvements but not without occasional showery rainfalls, temperatures may be somewhat closer to normal for a few days (18-20 C), but the very long range charts show another cool, showery interval by mid-August too.

    For BRITAIN, much of the above scenario will be quite similar for the northern half of England, much of Wales, and southern Scotland. In southern England, generally somewhat more settled through this coming week, while some of the rain will reach the southeast as scattered showers or even thunderstorms, there will be longer dry spells and somewhat higher temperatures in the range of 18-22 C. Late Sunday there may be a stormy outbreak when hot and humid air masses over Europe try to force their way north into the warm sector of the Atlantic low, but they won't quite make it to southeast England before being lifted off the surface helping to fuel heavy storms there.

    Over most of NORTH AMERICA, hot weather has returned and once again it was the warmest day of the year so far in several locations such as Toronto, Montreal and New York City. In the far west, it is also hot but less humid, and my local weather on Wednesday was sunny with a high near 31 C.

    Forecasts for Ireland



    Astronomy note: Full moon occurs today at 11:43 a.m. Irish summer time, and the moon is close to perigee which occurs on the 2nd of August.


    TODAY ... Some bursts of moderate or heavy rain with a few rumbles of thunder possible in the western half of the country this morning, followed there by gradual clearing in the afternoon, as fragments of this band of rain reach the eastern counties. Rainfall amounts 10-15 mm west but 5-10 mm east as the system weakens. Highs 16-18 C, rather humid even before the rain arrives.

    TONIGHT ... Partial clearing in the west, a few more showers likely east, and near the north coast, lows 8-11 C.

    SATURDAY ... Partly cloudy, breezy, some outbreaks of rain in northern Ulster and by afternoon near the south coast as well. Highs near 17 C.

    SUNDAY ... Increasing cloud east, overcast with rain in west. The rain will slowly spread further east but amounts will likely be considerably higher near Atlantic coasts, 15-25 mm by late in the day, just 5-15 mm eastern counties, and winds will also be stronger near south and west coasts (southerly 50-80 km/hr by afternoon and evening) than elsewhere (40-60 km/hr). Morning lows of 11-13 C and afternoon highs 16-18 C.

    MONDAY ... Some brighter intervals in strong south to southwest winds reaching 60-90 km/hr at times, then further showers developing, possibly heavy at times in western counties by later afternoon and evening. Morning lows 12-14 C and afternoon highs 16-19 C. About 10 mm further rainfall in some western counties.

    TUESDAY ... Windy with occasional showers, somewhat cooler again with lows near 10 C and highs near 16 C. Winds southwest 30-50 km/hr.

    WEDNESDAY-THURSDAY ... A secondary disturbance will form in the wake of the slowly dying Atlantic system and this may spread heavy rain across some western and possibly other regions, with 10-30 mm potential. Temperatures will be rather steady in the 13-17 C range.

    FURTHER OUTLOOK ... Somewhat improved beyond Friday7th with temperatures closer to seasonal normals and showers less frequent.

    My local weather on Thursday was sunny and hot with a high near 34 C.

    Forecasts for Ireland



    TODAY ... Partly cloudy, breezy, some outbreaks of rain in northern Ulster and redeveloping this afternoon near the south coast as well. Most places will remain dry but 2-5 mm could fall in a few places. Highs near 17 C.

    TONIGHT ... A few outbreaks of light rain, foggy or misty especially over higher terrain, and lows 10-13 C.

    SUNDAY ... Increasing cloud east, overcast with rain in west. After some scattered morning showers, the heavier rain will slowly spread further east but amounts will likely be considerably higher near Atlantic coasts, 15-25 mm by late in the day, just 5-15 mm eastern counties, and winds will also be stronger near south and west coasts (southerly 50-80 km/hr by afternoon and evening) than elsewhere (40-60 km/hr). Afternoon highs 16-18 C.

    MONDAY ... Some brighter intervals in strong south to southwest winds reaching 60-90 km/hr at times, then further showers developing, possibly heavy at times in western counties by later afternoon and evening. Morning lows 12-14 C and afternoon highs 16-19 C. About 10 mm further rainfall in some western counties.

    TUESDAY ... Windy with occasional showers, somewhat cooler again with lows near 10 C and highs near 16 C. Winds southwest 30-50 km/hr.

    WEDNESDAY-THURSDAY ... A secondary disturbance will form in the wake of the slowly dying Atlantic system and this may spread heavy rain across some western and possibly other regions, with 10-30 mm potential. Temperatures will be rather steady in the 13-17 C range.

    FRIDAY to SUNDAY is also looking rather unsettled with more outbreaks of moderate rain at times, with highs around 17 C.

    FURTHER OUTLOOK calls for generally similar conditions although with some improvement likely in terms of temperatures being a bit closer to average and rain showers somewhat less frequent.

    For BRITAIN, the above forecast scenario will be quite similar for most regions but southeast England will be a few degrees warmer and rain may be more concentrated in a few thunderstorms that develop late Sunday and again on Monday afternoon. Highs in some parts of southeast England could reach 24 C during this period.

    Heat continues over many parts of NORTH AMERICA. It was a hot and sunny day here on Friday with a high near 33 C.

    Forecasts for Ireland



    ALERT for heavy rainfalls (20-35 mm next two days) and strong winds gusting to 100 km/hr, see forecast for more timing details -- the rain will become heavy in western counties tonight and the strongest winds will develop later Monday.

    TODAY ... Rain gradually pushing further north to allow for some dry intervals in the east, but heavier pulses of rain will develop across the western counties with the risk of torrential downpours by late afternoon and evening. Rainfalls by about midnight will total 20-30 mm in western counties, 5-15 mm eastern counties. Winds throughout will be slowly increasing from a southerly direction reaching 40-70 km/hr by afternoon and evening. Very humid with highs about 16 to 18 C.

    TONIGHT ... Heavy rain and possible thunderstorms will become more showery towards morning, in a strong south to southwest wind reaching 50 to 80 km/hr in exposed locations around the south and west coasts. Lows will be rather mild at 11-13 C.

    MONDAY ... Partial clearing for at least the morning (lasting longer in eastern counties), but becoming very windy (southwest 60-100 km/hr) with further showers developing (5-10 mm) although these may be more prolonged in the west. Highs 16 to 19 C warmer in eastern and inland (central) regions.

    TUESDAY ... Not quite as windy although maintaining a steady southwesterly at 40-60 km/hr with passing showers, some sunny intervals, lows 9-11 C and highs 16-18 C.

    WEDNESDAY ... Cloudy with periods of rain developing late in the day and becoming heavy or even torrential overnight into Thursday morning. Temperatures steady 16-19 C.

    THURSDAY ... Rain ending, humid but somewhat fresher by afternoon in a moderate southwest to west breeze (40-60 km/hr). Lows near 10 C and highs near 17 C.

    FURTHER OUTLOOK ... Once again we are seeing different model scenarios, and at this point I would expect the more unsettled scenario to be more likely to verify but at least there is some chance of improvement given the spread in guidance available. The problem is that the cold pool of Atlantic surface temperatures north of the Azores will not dissipate very quickly, and seems to be wreaking havoc with the weather models (and the weather).

    I mentioned this earlier, but the advancing storm, while not technically a tropical storm, will have some characteristics of a tropical system. But it's over waters that are too cold for true tropical development. See previous forecast for comments on BRITAIN and NORTH AMERICA. My local weather has remained sunny and very hot through Saturday and little change is expected until Tuesday here. The high on Saturday was about 32 C.

    Forecasts for Ireland



    ALERTS for strong winds developing through the day, gusts to 110 km/hr possible in exposed south and west coast locations, 90 km/hr in other regions. Also part two of the ongoing rainfall alert with a second wave of moderate to heavy rain likely tonight, 10-20 mm on average. ADVANCE ALERT for some locally heavy rainfalls Wednesday in central counties, potential for 25 mm.


    TODAY ... Partial clearing for at least the morning (lasting longer in eastern counties), but becoming very windy (southwest 70-110 km/hr exposed south and west coast and 60-90 km/hr elsewhere), strongest winds appear likely in the late afternoon hours and peak gusts could reach 60 knots, note also these gales will be howling most of the day offshore, then further showers will be redeveloping (5-10 mm), becoming more prolonged in the west. Highs 16 to 19 C warmer in eastern and inland (central) regions.

    TONIGHT ... Intervals of moderate to heavy rain, total rainfalls 10-20 mm, with the strongest winds peaking before midnight then slowly moderating to about 40-70 km/hr by morning. Lows 10-13 C.

    TUESDAY ... Not quite as windy although maintaining a steady southwesterly at 40-60 km/hr with passing showers, some sunny intervals, a further 3-5 mm of rain, and highs 16-18 C. Partial clearing for part of the evening and early overnight hours.

    WEDNESDAY ... Cloudy with periods of rain developing and becoming heavy or even torrential around mid-day or afternoon in some central counties (the track may be adjusted but at this point it appears that a zone of heavier rain could fall from about Cork to Westmeath during the day, and into east Ulster by early overnight into Thursday morning, with 15-25 mm possible. Other regions could see lesser amounts in the range of 5-10 mm. Temperatures steady 16-19 C.

    THURSDAY ... Rain ending, humid but somewhat fresher by afternoon in a moderate southwest to west breeze (40-60 km/hr). Lows near 10 C and highs near 17 C.

    FRIDAY ... Variable cloud, a few showers or intervals of rain developing, lows near 8 C and highs near 17 C.

    SATURDAY ... Sunny intervals, highs near 18 C.

    SUNDAY ... Rain likely, highs near 17 C.

    FURTHER OUTLOOK ... Charts continue to look more settled for the second week of August, we shall see about that. Temperatures might then be closer to August normal values of 19-21 C.

    Over in BRITAIN, the advancing storm will have similar effects on Scotland and some parts of northern England, northern Wales, but will be less windy for the south where it will warm up to about 23 C. Eventually some heavy thunderstorms could develop there, but persistent heavy rain is likely further north. When the mid-week system moves through Ireland, the heavy rain will then head for western Scotland and other parts of Britain will briefly get considerably warmer (23-26 C) until the cold front of this low sweeps across the U.K. on Thursday.

    In NORTH AMERICA a strong cold front has brought heavy thunderstorms overnight to the lower Great Lakes regions and it will stay cool today north of the Ohio valley and Atlantic coast, but the larger cities on the coast will remain hot and humid with later thunderstorms. In the west, we're continuing to see hot and dry weather in most cases, with scattered storms over northern B.C. and also in parts of the Utah and Colorado region. My local weather on Sunday was very warm but with considerable high cloud dimming the sun, and the high was about 30 C. Monday is also a holiday in most parts of Canada, but not in the U.S.A., or (if memory serves) in Quebec.

    Tuesday, 4 August, 2015

    Forecasts for Ireland



    TODAY ... Not quite as windy, although southwest breezes will remain in the range of 40-70 km/hr for most of the day. Some fairly persistent light rain will be found in parts of Ulster (5-10 mm), but elsewhere showers will be generally brief if perhaps blustery in a few cases, and amounts will generally be about 1-3 mm. Highs near 16 C west and north, 18 C south and east, where a few sunny breaks could develop.

    TONIGHT ... Rain will gradually spread in from the south and may become rather heavy by early morning in west Munster. Parts of Leinster and Ulster could have a mostly dry although cloudy night. In general, winds will back to southerly 20-40 km/hr, and lows will be in the range of 10 to 13 C.

    WEDNESDAY ... Periods of rain may become heavy in the west-central counties where amounts of 15-25 mm are possible. The southeast and east may see somewhat less rain (5-15 mm) and could have some dry intervals between showery outbreaks. It will be rather close with highs 16-18 C and high humidity levels.

    THURSDAY ... Clearing from west to east during the night, and becoming rather cool with lows inland west 5-8 C, but staying 8-11 C east under mostly cloudy skies once evening rainfall tapers off to drizzle and ends with fog patches. Then the day should be mostly dry with a roughly equal mixture of cloud and sun, just a few isolated light showers possible. Highs 15-17 C.

    FRIDAY ... Occasional showers (2-4 mm) but some sunny intervals, lows about 7 to 9 C and highs 16 to 19 C.

    SATURDAY ... Sunny intervals, breezy, rain developing in the west by evening but otherwise a dry day. Lows 7-9 C and highs 18-20 C.

    FURTHER OUTLOOK ... Occasional rain Sunday-Monday, highs near 19 C, then possibly a slight improvement overall with more influence from high pressure for a change, although with weak disturbances off to the south at times spreading cloud from that direction, if not rain which may stay offshore mostly when it does threaten. Temperatures next week could be a bit closer to August averages which are 18-21 C.

    My local weather was mostly sunny despite some high cloud and the high inland where I spent the day was 30 C, closer to home base apparently 25 C.

    Wednesday, 5 August, 2015

    Forecasts for Ireland



    TODAY ... Rain may be heavy at times, with west-central counties most likely to see higher totals of 15-25 mm, but elsewhere 10-15 mm will be widespread. The rain may become showery at times in south Leinster especially, and an isolated thunderstorm could then develop. Highs 16-18 C with high humidity levels.

    TONIGHT ... Rain gradually ending across the east, but clearing around late evening in parts of the west. Fog patches may develop, and lows will range from about 7 C inland west to 10 C east.

    THURSDAY ... Partly cloudy with some decent sunny spells and just a few isolated showers. Many places will stay dry for the day. Highs 16-19 C.

    FRIDAY ... Cloudy with sunny intervals, occasional showers but amounts rather slight (1-3 mm). Morning lows 7-10 C and afternoon highs 15-18 C.

    SATURDAY ... A sunny start to the day with increasing mid-day cloud, some rain arriving in western coastal districts by late afternoon or evening, then slowly advancing eastwards during the evening and overnight hours. Morning lows 7-9 C and afternoon highs 17-20 C warmer in the east. Rather breezy especially near south and west coasts where southerly 40-60 km/hr.

    SUNDAY ... Mostly cloudy with a few brighter intervals, once the morning rain ends and moves east. A few more showers may follow. The total weekend rainfall will probably average about 5-10 mm. Highs on Sunday 16-18 C.

    FURTHER OUTLOOK ... This pattern of alternating dry and wet spells lasting a day or two will continue with temperatures not far from seasonal averages.

    My local weather on Tuesday was mostly sunny and somewhat cooler than recent days at 24 C, with considerable towering cumulus over northern horizon from a slowly advancing front that promises some scattered showers today.

    Thursday, 6 August, 2015

    Forecasts for Ireland



    TODAY ... Partly cloudy with some decent sunny spells and just a few isolated showers, most likely to be found this afternoon in the inland south. Many places will stay dry for the day, but 5-10 mm local amounts are possible around Tipperary, Kilkenny, Carlow and nearby areas. Highs 16-19 C.

    TONIGHT ... Some clear intervals, mist or fog patches, lows 7-10 C.

    FRIDAY ... Cloudy with sunny intervals, occasional showers but amounts rather slight (1-3 mm), and afternoon highs 15-18 C.

    SATURDAY ... A sunny start to the day with increasing mid-day cloud, some rain arriving in western coastal districts by afternoon or evening, then slowly advancing eastwards during the evening and overnight hours. Morning lows 7-9 C and afternoon highs 16-19 C, warmer in the east. Rather breezy especially near south and west coasts where southerly 40-60 km/hr and some higher gusts developing around Cork and Kerry by evening.

    SUNDAY ... Mostly cloudy with a few brighter intervals, once the morning rain ends and moves east. A few more showers may follow. The total weekend rainfall will probably average about 5-10 mm. Highs on Sunday 17-20 C.

    MONDAY ... Cloudy with sunny intervals, isolated showers, lows 10-12 C and highs 17-19 C.

    FURTHER OUTLOOK ... There might be a couple of relatively dry and slightly warmer days midweek, then the weekend factor returns with lows forming off to the south and spreading moisture back from east to west. This scenario is somewhat tentative and there could be a different outcome to report in the intervening eight or nine days, but the current maps look rather cool and unsettled for the weekend of 15th-16th. Still, there are faint signs of ongoing improvements large scale as higher pressure edges closer to Ireland on average through this outlook period despite the temporary interruption I just mentioned. I am going to stick with my idea that the end of August or early September might provide the best part of this rather uninspiring summer (my contacts tell me that the general mood is that the summer has been so-so in the east and rather dire in the west, so far anyway).

    Most of the above scenario will be similar for BRITAIN but note if you have plans to travel there, Sunday will probably remain overcast and showery most of the day as the overnight rainfall in Ireland slowly moves away to the east.

    We've had quite a change in the weather in western Canada and the northern half of the western U.S., with much cooler temperatures on Wednesday and widespread showers and some severe storms further inland. My local weather was mostly cloudy with just some light showers and the high was only about 17 C, probably the coldest day here since April in this rather unusual year.

    Friday, 7 August, 2015

    Forecasts for Ireland



    TODAY ... A mixture of cloudy and sunny intervals, with a few showers but amounts rather slight (1-3 mm) with many locations remaining dry, and afternoon highs 15-18 C.

    TONIGHT ... Clear intervals, lows 5-9 C.

    SATURDAY ... A sunny start to the day with increasing mid-day cloud, some rain arriving in western coastal districts by afternoon or evening, then slowly advancing eastwards during the evening and overnight hours with afternoon highs 16-19 C, warmer in the east. Rather breezy especially near south and west coasts where southerly 40-60 km/hr and some higher gusts developing around Cork and Kerry by evening.

    SUNDAY ... Overnight rainfalls of 5-15 mm then cloudy with sunny intervals once the morning rain ends and moves east. A few more showers may follow. The total weekend rainfall will probably average about 5-10 mm. Highs on Sunday 17-20 C.

    MONDAY ... Partly cloudy with sunny intervals, a few isolated showers, lows 10-12 C and highs 17-19 C.

    TUESDAY ... Sunny intervals, highs 17-19 C.

    FURTHER OUTLOOK ... A gradual increase in cloud and then rain can be expected later in the week into the following weekend, but it could stay relatively settled until Thursday. By this summer's standards this will be an improved pattern.

    My local weather started out cloudy and rather cool but the sun gradually broke through during the afternoon and highs reached 21 C. Meanwhile, severe storms continued in parts of the west-central regions with a tornado reported in southeast Alberta.

    Forecasts for Ireland



    TODAY ... Some morning sunny intervals with increasing cloud, rain gradually spreading into western coastal counties this afternoon but holding off for central and eastern counties until evening. Becoming rather windy (southerly 40 to 70 km/hr) with highs ranging from 16 C west and north to 19 C inland south and east.

    TONIGHT ... A few heavy showers developing but gradually clearing from west to east towards early morning. Total rainfalls (including what may fall during the day in west) 5-15 mm, and overnight lows 11-13 C.

    SUNDAY ... Cloudy with sunny intervals, just a few isolated showers redeveloping mid-day or afternoon, highs 16 to 19 C, with moderate southwest winds 30-50 km/hr.

    MONDAY ... Partly to mostly cloudy with a few showers, heavy at times in some northern counties. Morning lows 8-11 C and afternoon highs 15-18 C.

    TUESDAY ... Breezy and rather cool with a few passing showers but some sunny intervals too, lows 6-9 C and highs 15-18 C.

    WEDNESDAY and THURSDAY are looking dry and a bit warmer again with highs closer to 20 C.

    OUTLOOK for FRIDAY and the WEEKEND (15th-16th) cooler and unsettled with highs only 14-17 C.

    My local weather on Friday was sunny with a few clouds around and highs about 23 C.

    Forecasts for Ireland



    TODAY ... Cloudy with sunny intervals, just a few isolated showers redeveloping mid-day or afternoon, highs 16 to 19 C, with moderate southwest winds 30-50 km/hr.

    TONIGHT ... Showers developing, risk of thunder especially in parts of north and west, 10-15 mm rainfalls by mid-day Monday ... lows 8-11 C.

    MONDAY ... Partly to mostly cloudy with a few showers, heavy at times in some northern counties with risk of thunder. Morning lows 8-11 C and afternoon highs 15-18 C.

    TUESDAY ... Breezy and rather cool with a few passing showers but some sunny intervals too, lows 6-9 C and highs 15-18 C.

    WEDNESDAY ... Increasing cloud but some decent sunny intervals likely, morning lows 5-8 C and afternoon highs 17-20 C. By the overnight, cloud spreading in from east followed by light rain, best chance of clear skies for viewing Perseids probably inland southwest.

    THURSDAY ... Outbreaks of light rain but details may change as to regions, at present it looks somewhat more likely to be east-central then becoming showery as rain moves mainly northwards. Highs 16-18 C.

    FURTHER OUTLOOK ... Unsettled and rather cool for mid-August, highs 15-18.

    My local weather on Saturday was overcast with a few light showers developing in the afternoon, and the high was about 20 C.

    Monday, 10 August, 2015

    Forecasts for Ireland



    TODAY ... Partly to mostly cloudy with a few showers, heavy at times in some northern counties with risk of thunder. The heaviest of this activity should be clearing east by afternoon, 10-15 mm could fall in northern counties, just 3-7 mm for south, with afternoon highs 15-18 C. Moderate southwest to west winds 40-70 km/hr with a few higher gusts possible in exposed coastal areas.

    TONIGHT ... Clear intervals but still the risk of a few passing showers in moderate westerly breezes, lows 6-9 C.

    TUESDAY ... Breezy and rather cool with a few passing showers but some sunny intervals too, lows 6-9 C and highs 15-18 C. Although not the peak night, those interested might want to note that skies might be clearer Tuesday night than the following night (in the east at any rate) for viewing the Perseids

    WEDNESDAY ... Sunny intervals with increasing cloud near both east and west coasts as well as near the south coast, morning lows 5-8 C and afternoon highs 17-20 C. By the evening or overnight hours, cloud spreading in from south and east followed by light rain, best chance of clear skies for viewing Perseids probably from inland southwest north into central Ulster.

    THURSDAY ... Outbreaks of light rain but details may change as to regions, at present it continues to appear somewhat more likely to be east-central, south coast and eventually east Ulster, but a weaker system could also be trying to advance into northwest Mayo and west Galway. Confidence in forecast solutions only moderate ... models are generally showing low pressure tracking past southeast Ireland into south-central Britain and this would be the source of the heavier rainfalls in the southeast. But if that system is either weaker or further south than now expected, the result might be just dry cloud or very light rain. Highs will probably be around 18 C for most, but could reach 20 in some central counties. The heavier the rain turns out to be, moderate northeast winds would also become stronger and (for Leinster) more gusty, more intense solutions suggest 40-60 km/hr.

    FRIDAY ... A few more showers, rather cool daytime, lows 10-12 C and highs about 15-17 C. Winds remaining northerly but backing westerly later in the day. Further rainfalls about 2-5 mm at most.

    WEEKEND OUTLOOK ... Variable cloud, somewhat unsettled although rainfall amounts may be relatively slight. Somewhat cooler than normal with highs about 17 C.

    FURTHER OUTLOOK ... The following week is not looking much warmer either, with occasional showers in a continuing west to northwest flow pattern.

    For BRITAIN, today's heavier showers are likely to reach central regions around mid-day or afternoon. One or two severe thunderstorms could develop as a result. The above forecast will then be fairly similar to conditions in most parts of Britain but the rain arriving on Thursday and continuing in some parts most of Friday will probably be heavier, 20-40 mm could fall (currently looks more like 10 mm in southeast Ireland at most).

    My local weather meanwhile was partly cloudy with a high near 22 C on Sunday. Will post some forecasts for the PGA golf event in Wisconsin in tomorrow's outlook -- congrats to Shane Lowry and Irish golf fans in general.

    Note to readers -- planning some holiday time in the next two weeks, so there may be some guest forecasters soon (not before Thursday but likely soon after that). -- MTC

    Tuesday, 11 August, 2015

    Forecasts for Ireland



    TODAY ... Cloudy with some sunny intervals developing at least in southern half of the country, a few passing showers more frequent in west and north but amounts generally slight (1-3 mm). Moderate westerly winds and feeling rather cool, highs 15-18 C.

    TONIGHT ... Gradual clearing, could be good conditions for viewing the Perseids meteor shower (it is recommended to watch from dark rural locations, between midnight and dawn, and look to the northeast as that's where they usually originate). Lows will reach 5-8 C so dress warmly.

    WEDNESDAY ... Sunny intervals, light winds. This may be one of the better days of the summer. Highs 19-21 C.

    WEDNESDAY NIGHT ... Another fairly good viewing night for the Perseids, and this is the peak night too, but somewhat more cloud could spread in from the south and east towards midnight, with a slight risk of light rain near the southeast coast by dawn. Lows again 5-8 C except closer to 10 C in parts of the southeast.

    THURSDAY ... Cloudy in parts of the east and south, with the risk of some rain near coasts (the latest guidance shows almost all of this rain narrowly missing Leinster and heading for Wales, but not totally avoiding Wexford or Wicklow, later further north into coastal Leinster and east Ulster). Sunny intervals likely to continue further west. Some moderate northeast to north winds will develop but may only be a big factor in exposed coastal areas. Highs 16-19 C for most, 20-21 C possible inland west-central.

    FRIDAY ... Breezy, turning considerably cooler with a few outbreaks of showery light rain, winds northerly backing to westerly 40-60 km/hr. Morning lows about 7 C and afternoon highs near 16 C.

    WEEKEND OUTLOOK ... Further outbreaks of rain likely, highs 15-18 C.

    FURTHER OUTLOOK ... There could be the occasional dry day but the pattern looks a bit unsettled and cool, rainfalls would be generally rather light and temperatures probably a degree or two below average.

    Over in BRITAIN, some fairly pleasant weather until Thursday, then some rather heavy rain likely especially in the south-central, and western counties of the southern two thirds of England and much of Wales. This rain could last into Friday and amount to 40-60 mm in some places (this is why we hope that the core of this system will continue to avoid hitting land in southeast Ireland, as it moves out of the Biscay region towards the Channel).

    Hot and dry in much of the western half of North America again as well as across the southern U.S., outbreaks of heavy rain in parts of the eastern states and southern Ontario. This system has already moved past the site of the PGA golf event in Wisconsin, the next few days there will be seasonably warm and mostly settled with slight risks of brief showers or thundershowers, highs 24-27 C. By the weekend it could be hotter there with highs closer to 30 or 32 C. My local weather on Monday was sunny by afternoon and quite hot inland, 28-30 C.

    Will be posting forecasts until Thursday morning then off for about ten days.

    Forecasts for Ireland



    TODAY ... Sunny with a few cloudy intervals mainly confined to Connacht, pleasantly warm with highs 18-21 C. Light winds with sea breezes setting in near most coastlines. These usually only penetrate about 10-20 km inland and lose their cooling effect even before that.

    TONIGHT ... Clear with increasing high cloud across the south and east, probably good viewing conditions for the Perseids especially central, inland west and north. Cool with lows 5-9 C.

    THURSDAY ... The most recent guidance keeps the rain very close to the coast of Wexford and then only for a part of the mid-day period, with a similar trend northwards later in the day. Sometimes these situations revert at the last minute to earlier forecast models so we can't rule out some coastal rain yet but the chances appear to be about one in three at this point. While the most likely amount is now trace to 1 mm, the chance of 10 mm is about 20-30%, but even that would be confined to the immediate coastal fringes from Wexford north.

    In any case, most central and western regions will certainly escape the rain and perhaps some of the cloud too. As a result, highs will reach 19-20 C in those areas and perhaps 17 C near the east and southeast coasts. Moderate northeast breezes will develop and may be somewhat of a factor in Leinster.

    FRIDAY ... Variable cloud and moderate northeast backing to northwest then westerly breezes as low pressure moves through Britain and towards eastern Scotland. This will pull in a new batch of cooler Atlantic air and hold temperatures down somewhat, lows 7-9 C and highs 15-17 C. Rainfalls will be generally slight, 1-3 mm.

    WEEKEND OUTLOOK ... Generally cloudy, somewhat on the cool side, and increasingly unsettled with a chance of some persistent rainfall Sunday evening into early Monday. Highs both days of the weekend 16-18 C.

    FURTHER OUTLOOK ... Remaining rather cool and unsettled but with the occasional dry day thrown into the mix.

    See yesterday's forecast for comments on Britain and North America which still apply to today's update. My local weather on Tuesday was sunny but with extensive haze (especially where we went for the day, into the local mountains, due to drifting forest fire smoke haze). It was quite hot away from the shore, reaching 32 C in the Fraser valley and 30 C in the city.

    So, I'll post an update tomorrow morning your time, and then tomorrow morning my time will be off on vacation for a while.

    Enjoy your well deserved holiday M.T., and even though it's been a very disappointing Summer for us here in Ireland, I've still checked your forecasts on a daily basis, hoping and praying that there might be some good spell of good weather for us on the horizon. On the basis that you're not here for the next two weeks +, do you see anything good in August, or can we write off August as well?


  • Registered Users Posts: 14,331 ✭✭✭✭M.T. Cranium


    Thanks, I am looking forward to some time away from the city and the internet, and no I don't expect much if any improvement once this current dry spell breaks down late tomorrow into Friday. The most recent run of the GFS shows mostly Atlantic influences and the occasional strong front but mostly just slightly unsettled and cooler than normal by a degree or two in the next two weeks. I have the feeling that a good week could materialize near the start of September but later on the autumn will probably become rather stormy. As long as the Atlantic retains the large pool of anomalously cold water north of the Azores (it now covers most of the Atlantic north of 45-48 N from west to east) it is difficult to see how long settled periods can develop because the jet stream is naturally going to run along the southern edge of this cold pool and low pressure will therefore dominate the circulation.

    On a much shorter time scale, would now say that tonight's best sky viewing for the Perseids or any other items of interest would be on the western flank of the Dublin-Wicklow hills and as far west as Laois, Offaly. Not ruling out reasonably good views after midnight east of the hills but higher cloud will likely start to encroach from Wexford and could reach Wicklow around 0200h.

    I hope to get a good view here also, as skies are looking to be clear tonight, will have to pick a good spot outside the main light pollution zone. As I mentioned in an earlier forecast, the best time for viewing the Perseids is usually midnight to 0300h and one should be looking northeast to spot the fireballs, many (not all) of which will originate in that part of the sky. The moon will not be a problem for viewing this year, as new moon occurs on Friday so it would only be seen a few minutes before dawn tonight, if at all.

    Good luck if you do plan an attempt to catch the show tonight.

    The latest on the near-miss rain situation is that it should edge up the east coast all day tomorrow and might make an appearance within 5-10 kms of the shore at some point but I'm still a bit suspicious of the actual developments and noticing some potential for the rain to spread a bit further west at some point during the day. It should be a fine day in most of the western half or even two-thirds of the country. Another weaker band of light rain is making equally slow progress from the northwest but that one will eventually begin to overspread many areas Thursday night into Friday while the eastern rain consolidates over western Britain where it might prove to be fairly heavy in parts of Wales and Lancashire, Cumbria, even possibly southwest Scotland and that could spread back into a few parts of east Ulster too.

    Forecasts for Ireland



    TODAY ... Sunny intervals will continue in many parts of the western and central two-thirds, but it will be partly to mostly cloudy in the eastern third and near parts of the south as well as northwestern coasts. Cloud will hold daily maximum temperatures down to about 17-19 C. Sunshine could boost them into the 20-22 C range. Rain is going to move slowly north near the east coast later today and could touch the coast at times. Winds will begin to increase by mid-day from a northeasterly direction near the east coast but otherwise winds will probably stay rather light.

    TONIGHT ... Cloud will become more widespread although a few clear spots will remain near the central (north-south) counties, so that overnight lows could vary from 10-12 C around most coastal regions to 6-9 C inland. Light rain or drizzle may move onto both eastern and northwestern coasts from two separate frontal bands. The eastern one will produce heavy rain just offshore and into western parts of Britain, and that could make a landfall north of Dublin although confined to areas within 5-15 kms of the coast.

    FRIDAY ... Morning showers or periods of rain in north Leinster, east Ulster and also parts of north Connacht and Donegal. Possibly remaining dry in other regions except for one or two isolated showers. Highs 16-19 C. Moderate north winds backing to west then southwest later in the day.

    WEEKEND OUTLOOK ... Partly cloudy skies both days, isolated showers, and risk of some rain late Sunday into early Monday near the south coast. Highs both days near 17 C.

    FURTHER OUTLOOK ... Unsettled and rather cool much of the time with the occasional dry day in the mix, highs generally below normal in the 15-18 C range.

    Today and tomorrow will bring some 20-40 mm rainfalls to parts of England and Wales, and into parts of western Scotland by tonight. It will be rather warm and humid but I suspect some temperature forecasts in Britain may bust when the rain spreads in and drops temperatures to 16-19 C. Before it starts, the readings could be in the low 20s.

    I will now be off the net for about ten days and my next forecast will probably be around Tuesday 25th. Perhaps you'll find a few guest forecasters continuing the discussion in the meantime. My local weather on Wednesday was sunny, hazy and hot again, with a high near 30 C. I see one good chance for a bit of storm photography where we're planning to go, that being in eastern WA or northern Idaho around Tuesday, and I hope to have a few interesting cloud photos on my return. Heading out now to see if the Perseids will make a showing around here.

    Sunday 16th August
    Forecast for Ireland


    Today

    Some light rain in south Leinster and Munster this morning brighter elsewhere with a few showers, showers becoming more widespread this afternoon in most places, temps from 17C to 19 C with light winds.


    Tonight

    A few showers tonight with clear spells, temps 9C to 12C.


    Tomorrow

    Some sun but a lot of showers in the west and some maybe heavy, a bit dryer elsewhere with a few showers, temps 16C to 21C with light winds.


    Outlook

    The outlook is a bit uncertain at this stage but generally unsettled but not too bad, with rain at times on Tuesday and Wednesday temps about 20C, Thursday looks like it could be a dry day with just a chance of the odd shower, Friday could be a wet day and the weekend looking fair at this stage. So no real summer weather and as we move on through the month towards autumn it looks less likely that we'll get any long decent spell of good warm weather. their are tentative signs that early September could give us an Indian summer but's it's too far away at this stage.

    Forecasts for Ireland



    Thanks to those who helped out with forecasts during my recent holiday. We enjoyed mainly dry and warm conditions although a fair amount of forest fire smoke was drifting around the region for the past two weeks and continues to do so.


    TODAY ... Any morning sunshine in the north and east will quickly fade behind increasing cloud, followed by periods of rain and moderate east to southeast winds veering southerly later in the day, 40-60 km/hr. About 15-25 mm of rain may fall in parts of Connacht, Clare and possibly a few parts of the inland southeast. Expect 10-15 mm elsewhere. Highs only 14-17 C. Some improvement by afternoon in Munster.

    TONIGHT ... More rain, and some of it rather heavy in the western counties, where 10-15 mm additional may fall. Otherwise 5-10 mm and lows about 11 C.

    WEDNESDAY ... A few more bursts of moderate to heavy rain but also some brighter intervals, muggy and perhaps foggy in some coastal areas, with highs about 16-18 C. Further rainfalls of 5-10 mm possible.

    THURSDAY ... Partly cloudy with only brief and isolated showers, morning lows about 8 C and afternoon highs about 18 C.

    FRIDAY ... Showers or periods of light rain, lows near 10 C and highs near 17.

    SATURDAY ... Cloudy, a few showers but amounts likely to be only 1-3 mm, lows about 9 C and highs about 16 C.

    SUNDAY ... Periods of light rain, lows 11 C and highs 17 C.

    FURTHER OUTLOOK ... There may be some improvement for the week of early September, with higher pressure building in from the west, highs of about 18 to possibly 20-21 C later. This spell may eventually revert to the more unsettled theme of the current week.

    Not that much different in most parts of BRITAIN for the next week, and generally rather warm and humid in much of NORTH AMERICA. Erika has formed north of Guyana and will be heading towards the Caribbean with uncertain prospects for development, after Danny came and went in the past few days. My local weather has been sunny although somewhat hazy from forest fire smoke, not as bad here as further inland though. The high was about 23 C.

    Wednesday, 26 August, 2015

    Forecasts for Ireland



    TODAY ... Cloudy with a few brighter intervals, and a few more bursts of moderate to heavy rain, muggy and perhaps foggy in some coastal areas, with highs about 16-18 C. Further rainfalls of 5-10 mm possible.

    TONIGHT ... Some clearing with just isolated showers mostly near north and west coasts, lows 8-10 C.

    THURSDAY ... Partly cloudy with only brief and isolated showers, and afternoon highs about 18 C.

    FRIDAY ... Mostly cloudy, showers or periods of light rain, lows near 10 C and highs near 17 C.

    SATURDAY ... Cloudy, a few showers but amounts likely to be only 1-3 mm, lows about 9 C and highs about 16 C.

    SUNDAY ... Periods of light rain but with some risk of heavier rain developing in Leinster and east Ulster, winds rather brisk at times from northeast backing to northwest 40-70 km/hr, and lows 9-11 C, highs 15-17 C. Rainfall potential in the range of 10-30 mm.

    MONDAY ... A few more showers, but some brighter intervals likely too, with moderate northerly breezes, cool. Lows 7-9 C and highs 14-17 C.

    OUTLOOK ... There remains some chance of a settled period with at least some sunshine each day next week and this could last even towards the weekend of 5-6 September, but I remain concerned about this persistent "cold pool" of sea surface temperatures 4-6 degrees below normal to the west of Ireland -- it has rather consistently managed to overcome hints of settled weather this summer, with one or two exceptions, so let's hope this is another exception.

    The disturbance expected this coming weekend will be bringing some locally heavy rainfalls to western regions of BRITAIN and this is why any slight change in the trajectory might spread heavier rain back to the west into parts of Ireland too.

    Meanwhile, my local weather was sunny with some haze from distant forest fires, and it was somewhat cooler with a high near 20 C.

    Thursday, 27 August, 2015

    Forecasts for Ireland



    TODAY ... Rain may continue for most of the day in northern counties and showers, possibly a few thunderstorms, will develop in the west by afternoon. Parts of the south and east could have a relatively dry day with some sunshine at times. Highs 16-18 C.

    TONIGHT ... Partly cloudy, showers becoming less frequent. Lows 6-9 C.

    FRIDAY to SUNDAY ... Similar conditions each day, cloudy with a few sunny intervals, and scattered showers, slight chance of thunder, lows 5-8 C and highs 15-18 C.

    MONDAY-TUESDAY ... Breezy, very cool with a few showers, but a gradual clearing trend developing, in west to northwest winds 40-60 km/hr. Lows 4-7 C and highs 14-17 C, possibly as low as 12 C in a few parts of north.

    FURTHER OUTLOOK ... The models are still showing optimism about a dry interval from mid-week through the following weekend (5-6 September) with temperatures remaining on the cool side, particularly overnight lows which could get down close to ground frost levels (1-4 C) while highs would remain in the 16-19 C range. Some guidance suggests a slightly warmer interval in southeast winds by early in the following week, but it seems likely that cool and unsettled conditions would eventually return.

    Meanwhile, Tropical Storm Erika continues a rather fast westward motion into the northern Caribbean and some guidance suggests it could become a hurricane in the Bahamas or off the east coast of Florida by early next week. My local weather on Wednesday was hazy and a bit warmer at 24 C.

    Friday, 28 August, 2015

    Forecasts for Ireland



    TODAY ... Showers mainly confined to west this morning, will spread to other regions and become heavier with the risk of a few thunderstorms, 3-7 mm on average, and highs 14-17 C in moderate southwest winds.

    TONIGHT ... Partly cloudy, showers becoming less frequent, lows 7-9 C.

    SATURDAY ... Showers and the risk of a thunderstorm, highs 15-18 C.

    SUNDAY ... Continued unsettled with a few showers but also some brighter intervals, lows 6-9 C and highs 15-17 C.

    MONDAY ... Cool and breezy (W-NW 40-60 km/hr) with passing showers, lows about 5-8 C and highs 13-16 C.

    TUESDAY ... Little change although somewhat fewer showers in the mix, lows about 5-8 C and highs 13-16 C.

    WEDNESDAY 2nd September to about SUNDAY 6th will bring some welcome dry weather for most, just a few isolated showers at times near northern coasts, and considerable sunshine especially for the south and east, but staying quite cool with overnight lows sometimes in the 0-3 C range bringing early ground frosts, and highs generally 12-15 C north, 15-17 C south.

    This settled interval may turn a bit warmer eventually as light north to northeast winds become more southeasterly, and highs may reach 18-21 C. The spell will probably break down before mid-month with a return to cool, unsettled conditions likely.

    Meanwhile, my local weather on Thursday was sunny and quite warm at about 27 C.
