The frost for tonight and Sat night, is it going to be widespread MT?0
-
UPDATE _ Friday 8:10 p.m.
__________________
Frost potential looks patchy at worst tonight as there is fairly extensive cloud at present, a few spots probably around Tipps, Laois and Offaly may clear enough to bring a patchy ground frost. Saturday night looks like bringing a more widespread frost, will of course update that around 0600, but if you're wondering about a "killing frost" Sunday morning, I would say possibly yes except in larger towns which should stay 2-4 C warmer.0 -
Saturday, 25 September, 2010
______________________________
TODAY ... sunny with a few cloudy intervals (once any rural fog dissipates) and rather cool, but with the light winds, it should feel pleasant enough at mid-day (on the sunny side at least) ... highs 13-15 C.
TONIGHT ... frost more widespread than last night, with some readings as low as -2 C possible, 0-3 C in general, 5 C in more sheltered urban and coastal locations. Some dense fog patches likely by midnight to well after sunrise.
SUNDAY ... morning fog or low cloud, sun breaking through then a gradual increase in high cloud from southwest, remaining sunny in the east. Highs about 14 C. The following night may bring another light frost in counties north of Dublin and generally eastern half of Ireland, but overnight lows will stay up around 5-8 C further west.
MONDAY ... cloudy except for parts of Ulster, but dry in east generally, rain moving into southwest around mid-day, milder with southeast winds 10-20 mph, highs near 17 C.
TUESDAY ... cloudy with showers, heavy at times, winds SSE 15-25 mph, lows near 12 C and highs near 16 C. Rainfalls in total may approach 25 mms.
WEDNESDAY ... cloudy with periods of rain, a further 15-25 mms of rain, mild, foggy at times, lows near 13 C and highs near 16 C.
The weather may brighten somewhat later in the week but may remain rather showery, then could become windy by the weekend with gales possible from a generally westerly direction.
Meanwhile, Friday (24th) here was cloudy without much rain but damp, and about 16 C. On the east coast, Washington (DCA) had an astonishing high of 99 F or 37 C which was the latest in the year for such a high reading (although Thursday's record of 98 F was set back in 1895). The heat was widespread although sea breezes kept both NYC and BOS a little cooler near 29 C, but it reached 32 C as far north as Lake Ontario. This heat is now slowly modifying and will be followed by heavy rain by Monday. T.S. Matthew moved inland before it could become a hurricane but is bringing heavy rains to Honduras now, and Lisa continues to drift towards the Azores although it will probably die before getting close enough to give them much weather.0 -
Sunday, 26 September, 2010
_______________________________
It seems that frost avoided Ireland (or vice versa) and that's a good thing except for forecast verification purposes. Cloud kept the overnight lows around 6-7 C in most places. Over in the western part of the U.K., there have been a few substantial breaks and lows have in fact fallen to -1 C at a few spots (-3 C at Tulloch Bridge in Scotland). So consider your gardens the lucky ones this morning.
Going with the same general forecast beyond an increase in today's cloud cover ...
TODAY ... morning fog or low cloud, sun breaking through in a few places by late morning, then a gradual increase in high cloud from southwest (where visible through remnant low cloud), somewhat brighter in the east. Highs about 13-14 C and feeling quite chilly unless the sun breaks through the overcast.
TONIGHT may bring a scattered light frost in counties north of Dublin and generally eastern half of Ireland, although probably only in one or two spots, and overnight lows will stay up around 5-8 C further west, in fact temperatures may rise to 10 C later in the night there.
MONDAY ... cloudy except for parts of Ulster, but dry in east generally, rain moving into southwest around mid-day, milder with southeast winds 10-20 mph, highs 15-17 C. It could start off feeling quite raw Monday morning as milder air will be slow to mix down to the surface.
TUESDAY ... cloudy with showers, heavy at times, winds SSE 15-25 mph, lows near 12 C and highs near 16 C. Rainfalls in total may approach 25 mms.
WEDNESDAY ... cloudy with periods of rain, a further 15-25 mms of rain, mild, foggy at times, lows near 13 C and highs near 16 C.
THURSDAY ... partly cloudy, a few longer sunny intervals, then more rain moving in from the west, highs near 16 C.
FRIDAY ... periods of rain may become heavy at times, windy, highs near 15 C.
Next weekend is still looking very unsettled and breezy to windy at times, and the models are starting to deal with a possible intense frontal system for early in the week (around Monday 4th-Tuesday 5th October). That will become a hot topic if it stays on the model charts into "reliable time frames" as we like to call days 1-5 (usually) :cool: ...
Meanwhile, Saturday 25th was a sunny and pleasant day here with a high near 20 C, but only a brief respits from rain as that has already moved back in this evening. The east coast heat wave continued in somewhat reduced form with DCA hitting 34 C and NYC 31 C. This will now morph into more of a warmish period with rain moving in from the southwest. Matthew has dumped copious rains on central America, and Lisa continues a slow northward drift into obscurity southwest of Madeira.0 -
Next weekend could spell a testing Ryder Cup, you reckon?0

Monday, 27 September, 2010
______________________________
The Ryder Cup and a lot of other events are going to have to cope with some wind and rain apparently, if the models are right.
While much of this week will be cloudy and unsettled with frequent rain, stronger disturbances are being advertised for Sunday and Monday.
TODAY ... mostly cloudy with rain slowly edging east but probably remaining confined to Munster and nearby parts of Connacht, at least in terms of measurable rainfall which may reach 4-8 mms in the southwest. Winds will be picking up from the E to SE and giving a rather raw feel to the day especially before mid-afternoon, and highs will struggle to reach 13-15 C.
TONIGHT ... rain continuing to edge further east, foggy at times, chilly SE winds and lows 7-9 C.
TUESDAY ... variable cloud as one area of rain dies out near the east coast to be followed by a stronger impulse with heavier rain by late in the day, as winds become more southerly, highs reaching 17 C, winds SSE 15-30 mph.
WEDNESDAY ... cloudy with periods of rain, heavy at times in eastern counties, some clearing late in the day west, lows near 12 C and highs near 18 C, 15-30 mms of rain possible, winds S-SW 20-30 mph.
THURSDAY ... variable cloud with more heavy showers developing in southwest winds, lows near 10 C and highs near 17 C.
FRIDAY-SATURDAY ... continuing unsettled with frequent showers and blustery SW winds, lows near 10 C and highs near 15 C.
The models are then showing a stormy period on Sunday into Monday ... details are yet to converge but probably an interval of strong S to SW winds as deep low pressure moves through the northern half of Ireland around Sunday night.
The weather here today (Sunday 26th) was cloudy and mild with highs around 17 C. Heavy rain has hit just north of here and caused some severe flood damage up the coast around Port Hardy and Bella Coola, but we have not seen much rain here this weekend. It is also raining heavily (as golf fans may have noticed earlier) in the eastern U.S. where the heat wave is over, but temperatures remain near 20 C.
While Matthew and Lisa have dissipated, the watch is on for a new tropical system south of Jamaica -- it would probably become Nicole although the relation to Matthew's moisture may be taken into consideration for this to be Matthew part two. Whatever the name, it seems likely to move across Cuba and threaten southern Florida and then the southeast U.S. with heavy rains from a tropical storm.0 -
UPDATE _ Monday, 6 p.m.
_____________________
Various trough and frontal systems on their way in from the Atlantic appear to be weakening as they hit Ireland, probably because of the influence of the stationary low pressure over the North Sea. This trend should disappear gradually overnight and on Tuesday, but in the short term, what it means for the forecast is that this evening and first part of the overnight period may remain clear over parts of east Leinster and Ulster, with temperatures likely to fall to about 7-8 C folllowed by dense fog formation, as higher cloud moves in from the west. There is not much left of the first wave of moisture but it could re-develop overnight to some extent and give trace to 2 mm rain across central counties, later reaching the east coast by morning.
From that point on the original forecast sequence should continue valid with ever-strengthening waves of moisture moving in from the southwest.
The 12z model run seems to have started a slight downgrade in the intensity of storm systems timed for Sunday-Monday so we'll have to assess that trend later and for the morning forecast (sometimes you get a model tug of war at this stage).
If you do have clear skies this evening around 10-11 p.m., have a look for Jupiter in the southeast, now that the Moon is not in the sky at that time, it will be about as bright as you'll ever see it.0 -

Jupiter is indeed looking very bright in our clear sky but i must be imagining the very bright moon (about 2/3 full) to the east of it
P.S Weather for Ryder cup looking very wet and windy. Much more Harrington weather than team Casey :pac: Good shout Monty

It's a ringer for the moon ok or maybe a Chinese lantern stuck in space.0
-
Whoops, that's what I get for doing astronomy in my head, forgot that the Moon is both relatively slow and northing so it pops up a bit before my mental estimate for full moon plus four days. Still, it wasn't glaring right beside Jupiter, I presume (have not seen any night skies here for days now, hoping for a break because I want to have a look in my binocs for Uranus near Jupiter -- would recommend anyone consult a star chart if they want to find it, should be about as bright as some of the background stars in the area). On to the forecast then ... I did that in my head too (uh-oh). :eek:0

Tuesday, 28 September, 2010
______________________________
Models continue to offer somewhat different solutions towards the weekend and early next week -- all have an unsettled theme, some show stronger winds than others. I have blended the range into one forecast here today, but this could begin to diverge either way.
TODAY ... dry at first in eastern counties, especially Ulster which could remain dry until early afternoon ... some sunshine could break through the overcast there, but the west will definitely start out with rain, heavy at times, and could see a brief thundershower embedded, with 10-20 mms of rain possible ... that rain will tend to break to showers by afternoon, as the line moves further east, through central Ireland by afternoon and giving the east some rain eventually (3-5 mms). Warmer and more humid in general with highs 17-18 C, hill fog developing, winds increasing to S 15-25 mph.
TONIGHT ... occasional light rain, mist or fog becoming widespread, just a gentle SW breeze, and very mild, lows 11-13 C.
WEDNESDAY ... a rather variable day, some breaks in the overcast giving a few places a couple of hours of warm sunshine, but also some scattered and eventually widespread heavy showers, possibly thundery with hail. Winds from the SW at 10-20 mph, and rainfalls generally 5-10 mms but some places well above that range (most likely west central counties). Highs 17-19 C.
THURSDAY ... windy with periods of rain developing, heavy at times, wind increasing to SSW 20-40 (exposed west coast areas 30-50) mph, and potential for 20-30 mms of rain. Lows near 10 C and highs near 17 C.
FRIDAY ... continued windy (SW 20-40 mph), showers, lows near 11 C and highs near 15 C.
WEEKEND ... both days likely to be unsettled and windy with frequent showers. Winds becoming near gale force late Friday and early Saturday, possibly less blustery for a while, then another stormy period possible later in the weekend into early Monday. The prevailing wind will be SW in the range of 25-45 mph with higher gusts.
:eek::eek::eek:
We are faring no better here, today has been clammy and showery near 20 C with the air coming up from around Hawaii. Heavier rain has fallen further north and created further flood and mudslide problems "up the coast." Down around L.A. in southern California, they have been baking in a hot east wind (if that gets stronger, it's a Santa Ana wind, but so far it's just a slight breeze) giving all-time record highs that reached 45 C (113 F) at the downtown Los Angeles weather station. Oddly, the summer was considered unusually cool down that way and frequently five degrees below average for them (ths city of Los Angeles is usually a lot cooler than inland anyway, but they were recording highs of 18-22 C day after day in July rather than the normal mid to high 20s). Meanwhile, on the east coast, it remains rather warm and humid with some heavy rain at times, and a tropical storm seems to be forming near Cuba today that could become Nicole and should in any case (name or not) move north through Florida and up the east coast. This is where your forecast uncertainty is based, actually, because some models want to develop this rapidly and bring it screaming across the Atlantic on the weekend; others lose it in the general clutter of moving pieces around Newfoundland but still get something fairly energetic together for Ireland by about Monday-Tuesday. Hope you're not late for work now. :cool:0 -
You might be interested to know that we had a few very heavy showers in south wicklow [the East!] this morning between 930 and 1030 am followed by sunshine and they were breaking out ahead of the main front which only arrived here in the last hour.The rain in one of them was almost monsoonal with the sky very dark.TODAY ... dry at first in eastern counties, especially Ulster which could remain dry until early afternoon ... some sunshine could break through the overcast there, but the west will definitely start out with rain, heavy at times, and could see a brief thundershower embedded, with 10-20 mms of rain possible ... that rain will tend to break to showers by afternoon, as the line moves further east, through central Ireland by afternoon and giving the east some rain eventually (3-5 mms). Warmer and more humid in general with highs 17-18 C, hill fog developing, winds increasing to S 15-25 mph.0 -

A few miles south of Amia Careful Bobsled, in North Wexford, we had heavy showers in the early morning followed by light showers during the rest of the morning and early afternoon, the mid and late afternoon was dry but cloudy and the rain has only started recently.The aim of argument, or of discussion, should not be victory, but progress.

__________________________________
The models have downgraded any storm potential for the Sunday-Monday time period, mainly because of uncertainty about how Tropical Depression 16 near Cuba this morning will evolve into a tropical storm and enter the jet stream this weekend ... so this could change back but for the time being, the forecast will reflect a somewhat more placid pattern by the end of the weekend. Friday still looks very blustery and wet.
TODAY ... morning fog or mist will lift in most counties to allow for some brief warm sunshine, but western counties will have a scattering of thundery showers, some of them rather heavy ... this activity will tend to drift east to cover more of central and then eastern Ireland but a few places may remain dry all day ... where it does rain, expect 10-15 mms locally ... highs will be around 17 or 18 C. Winds will be moderate southwesterly.
TONIGHT ... foggy with a few more showers but these becoming more isolated, some dense fog developing with lows 8-11 C.
THURSDAY ... clouding over probably before the fog lifts in some areas, but the sun may be out briefly before another wave of moisture hits from the Atlantic, this one rather sporadic and becoming heavier by late in the day, with about 10-20 mms eventually ... winds increasing to SSW 20-35 mph ... highs near 17 C.
FRIDAY ... blustery with periods of rain evolving into heavy showers with some thunder and hail, winds SW 25-45 mph with some higher gusts, lows near 10 C and highs near 15 C.
SATURDAY ... partly cloudy, breezy, some further showers, winds SW 20-35 mph, lows near 9 C and highs near 15 C.
SUNDAY ... with some uncertainty attached, Sunday is looking a bit improved now with some sunny intervals, isolated showers and only moderate breezes from a westerly direction, highs near 16 C.
NEXT WEEK is still somewhat unsettled on the current charts and confidence in those is only moderate, as it could be more unsettled at times. Temperatures will probably average 1-2 degrees above normal throughout.
As mentioned above, Tropical Depression 16 is having a difficult time consolidating into a tropical storm but should get that designation some time later today east of Miami on its way north. There it will run into a frontal system that is managing to drop heavy rain without help from a tropical storm, so this could turn very heavy in parts of the southeast U.S. in the next two days. Where I live, the weather was much improved on Tuesday with sunny skies, some fair weather cumulus and a high of 20 C.0 -
Thursday, 30 September, 2010
_______________________________
ALERT for possible heavy rainfalls in total later today and especially tonight, with 25-40 mms possible by mid-day Friday in two waves as described below in the forecast. Spot flooding is possible and tonight, driving conditions will be poor due to fog as well as water accumulations on roadways.
TODAY ... rain will work its way across Ireland from west to east this morning and may be heavy at times with 10-15 mms on average ... then it may brighten for a while this afternoon before heavier rain arrives late in the day in the west. Winds will increase to SSW 20-40 mph. ... rather warm and humid with highs reaching 18 C.
TONIGHT ... rain, heavy at times (15-25 mms) with some embedded thunder ... winds continuing SSW 20-40 mph ... foggy with lows 12-14 C.
FRIDAY ... morning showers becoming confined to east by mid-day with some brighter intervals developing, winds veering to WSW 20-40 mph (and some higher gusts mid-day) with more showers developing in the westerly air flow ... highs 17-19 C.
SATURDAY ... partly to mostly cloudy, fog at times especially over higher ground, frequent showers, moderate S to SW winds, lows near 12 C and highs near 16 C. Rainfalls about 10 mms.
SUNDAY ... variable cloud, showers, some longer periods of rain developing mainly in the south, winds backing around to SE but not overly strong (it would seem at this stage) with low pressure tracking to the south taking more rain and wind into the U.K. and northern France (so while it won't be that great in Ireland, the weather is likely to be considerably more adverse in places like south Wales where they will be trying to finish up the Ryder Cup).
For Ireland, expect 5-10 mms of rain and lows near 10 C, highs near 15 C.
If you're interested, the weekend rainfalls could be 20-50 mms in parts of the U.K.
NEXT WEEK is still looking quite unsettled. The disturbance that was briefly Nicole off Florida today should be rounding the turn near Newfoundland on Sunday and heading for Ireland around Tuesday. That may turn out to be a strong wind and rainfall event as it hits the jet stream at full speed. Expect that around Tuesday night so mid-week may be particularly unsettled. Temperatures will stay above normal especially at night.
We had a very pleasant sunny day here on Wednesday (highs near 21 C) as the storm track has shifted far enough north to keep the rain in central B.C. now. It remains very hot in southern California. The east coast was warmer than average too but rain has spread up as far north as Philly now and while Nicole came and went, a strong low is forming off Florida that could bring five inches of rain to the Carolinas today and tomorrow.
Would suggest you check with the active thunderstorm potential thread for some other perspectives on today and tonight's active weather, and I will try to issue updates if awake. :cool:0 -
UPDATE _ Thursday, 7:00 p.m.
_________________________
Radar shows some moderate rain moving across the southwest this evening and this is spreading gradually east, but the main event that I described in the morning forecast is still out to the west of 20 W and will arrive around 0200h on the west coast spreading gradually across the country late tonight. That area is still developing and should become quite blustery and heavy in terms of rainfall amounts as it arrives. Wind gusts to about 45 mph (not quite a sustained gale) will develop and there could be brief gusts to 60 mph in a few exposed locations depending on how this front develops.
New guidance for Saturday is indicating an isolated area of heavy showers in addition to the general forecast details earlier, to affect mainly Connacht and in particular western Mayo. There could be some locally torrential rainfalls there as a small cluster develops in association with a trough rotating around the main storm centre near Iceland.
Sunday still looks rather unsettled and there could be long intervals of steady rain, although the heavier stuff will make a bee-line for Wales to try to fill the Ryder Cup (is there a Ryder Cup? I don't remember seeing it, just the golf and the dinners).
My research-touted mid-week storm from post-Nicole is now looking more possible with a strong energy centre being developed on several models arriving in Ireland late Tuesday. Watch for this one, it could have more of a connection between the upper and lower levels than any of these medium-strength disturbances coming along in the next few days (and so become more of a wind-producer).
Having another fine day here with not a cloud to be seen and 20 C expected. There has been a very heavy rainfall in parts of the Carolinas spreading up into Virginia, Maryland and Pennsylvania in association with Nicole's hybrid low or whatever you want to call it, actually post-Nicole is a lot more impressive than actual Nicole ever was. Meanwhile, Otto (yes, Otto) is trying to form east of the Windward Islands and could be with us as early as Friday morning. There is also a lot of potential left behind by Nicole and in that general area east of Florida another storm could develop some time over the weekend or early next week.0 -
You did ask
Just to keep on topic - weather is looking very wet for Sunday, esp at Celtic Manor.
They'll be keeping the lid on the cup.0 -
Congratulations Europe on an impressive win. (another forecast, but I've seen these U.S. guys trying to play in wind and rain, and other than Jim Furyk, the frustration factor is going to be enormous ... they will be counting the hours until they can get on the plane.)0

Yes, in the K Club in 2006 we hired the services of ex Gordon to literally rain on their parade and it worked, but will it work again? If it does we'll have to give these depressions names. Another contest for you to organise MT, Name That Storm!0 -
Actually, I think it should be called the Radar Cup :pac:0

UPDATE _ Friday, 0010h
____________________
Anyone wondering if the rain now spreading into Kerry is the main event should be advised that the main event is still out around 14-15 W and heading in rapidly but won't hit until about 0300h, however this batch now coming in looks like 3-5 mms by itself, so expect another 15-20 mms after that comes and goes.0 -
Friday, 1st of October, 2010
____________________________
TODAY ... periods of rain this morning, heavy at times, with south-southwest winds of 20-35 mph, then brighter from west to east around mid-morning towards early afternoon for eastern counties ... winds veering to west-southwest and gusty for a while before dropping off to 15-25 mph. A few more showers developing, possibly thundery in a few spots ... much of the rain has already fallen but expect a further 10 mms or so. Highs 17 or 18 C.
TONIGHT ... cloudy with occasional showers, hill fog becoming more of a general mist or patchy low-level fog, eventually some areas in very poor visibility with 3-5 mms of rain on average ... very mild with lows 9-12 C.
SATURDAY ... variable cloud, some heavy to torrential showers developing in Connacht especially but more scattered elsewhere, some with hail and thunder (western Mayo and nearby parts of Connacht as well as south Donegal could see some squally conditions). Rainfalls quite variable but between 5 and 20 mms ... highs 16-17 C. Winds WSW 15-25 mph with some briefly higher gusts.
SUNDAY ... overnight rain or drizzle, fog, with morning lows near 10 C ... the weather may brighten a little in western counties by afternoon but it seems likely to stay wet and rather gloomy in the east ... meanwhile the UK will be pounded by heavy rain and strong southerly winds, but in Ireland it should be a more moderate southeast wind backing to northeast ... highs 14-15 C and rainfalls varying from 5 mms northwest to 15-25 mms southeast (for the Ryder Cup event in Wales there could be a real downpour and I wonder if the competition will finish on Sunday at all).
MONDAY ... variable cloud, breezy, more showers or thundershowers developing, possibly heavy at times ... lows near 11 C and highs near 16 C.
TUESDAY ... mark this day down for a possible heavy rain and/or strong wind event with a sharp trough approaching, the remnants of "Nicole" ... timing may change more towards Tuesday night or even Wednesday but mid-week in general blustery and possibly stormy. Temperatures near 15 C.
After that blows through, another deep storm is indicated but this one is going to pull up short and head north, drawing much warmer air north from Biscay ... it may rain in Ireland at least in the west but some dry, warm periods may develop too (that's more likely for the U.K. and France).
There's nothing very chilly showing up for the first half of October on most of the charts. On the east coast of the U.S., a very warm September has ended with a massive rainstorm (over two feet of rain has fallen in parts of North Carolina and nearly four inches today in Washington, that's 100 mms). This is the remnant low of Nicole, and it's heading through NYC and Boston today on its way to Nova Scotia and Newfoundland on Saturday. This storm is followed by a much cooler regime that could see snow at higher elevations and off the Great Lakes at times before it warms back to normal next week.
The west coast continues to sizzle and it was even quite warm here today (Thursday 30th) at about 23 C under unbroken sunshine (there is no snow on the north shore mountains even at 1500m).
I may update today's forecast if anything blustery develops, but it seems that the system is staying rather sedate as it moves through, so far.0 -
UPDATE _ Friday, 1130h
___________________________
Conditions are becoming favourable for locally severe showers with hail and thunder across Connacht from about 1230 to 1700h ... satellite imagery shows this development over the near Atlantic waters and the cells should be moving inland this afternoon. Gusts to 50 mph, hail and locally heavy rain will accompany some of these showers, and there is a slight risk of a waterspout, funnel cloud or weak tornado being sighted.0 -
When is tropical storm Nicole due to hit New York I've read that subway might flood are they really going to get that much rain:eek:
http://gizmodo.com/5652348/new-yorks-subway-may-not-survive-tropical-storm-nicole0 -
It's moving through NYC at the present time, winds there have just shifted from south to northwest and rainfalls of 2-3 inches have been recorded. This is somewhat less than further west in NJ and into central New York state where 3-6 inches fell in the past day or so. There could be some local urban flooding but maybe not enough to stop the NYC subways. It was worse further south and there are a lot of flood problems across NC and VA.0

very heavy shower here. plenty of hail mixed in
EDIT: damn...wrong thread. hehe0 -
Saturday, 2 October, 2010
_________________________
TODAY will feature some heavy local showers with hail and thunder, spreading across parts of Connacht, west Munster and south Leinster this morning and further to the north and east by this afternoon. Ulster will stay dry and partly cloudy longer (except for Donegal) but eventually all regions will get some of this activity. It will remain strongest in Mayo and Galway as well as some parts of the southwest and southeast. Local rainfalls could reach 25 mms although the average will be closer to 5, and hail may be quite widespread. There will also be some longer sunny intervals in a few places. Winds moderate SSW (10-20 mph with some higher gusts) and highs about 16 to 18 C.
TONIGHT the showers will begin to die out except for a prolonged interval of rain lingering in the southeast and up the east coast about as far as Dublin, so that lows further west and north may drop off to 5-7 C while staying up around 10 to 12 C in some parts of the southeast. Rainfalls of 10-15 mms in the southeast, winds backing to SE 10 mph.
SUNDAY will be mainly cloudy with some brighter intervals developing in the central counties between two areas of more persistent cloud and light showers covering parts of the southeast and the west coast. In those areas there may be low cloud and fog over hills in some places. Winds will continue rather light from a generally SE to E direction, returning more to the S then SW later in the day in the west. Highs will be 15-16 C. (note some heavy rains will develop into southern parts of England and possibly into Wales by afternoon, from a southerly direction).
MONDAY will be cloudy with frequent showers and blustery S-SW winds at times, mild and rather humid with lows near 10 C and highs near 17 C.
TUESDAY will be mostly cloudy with showers at first, becoming blustery with periods of rain developing in strong SSW winds later, lows near 11 C and highs near 16 C.
WEDNESDAY will see the end of that system with gradual clearing and less blustery SW winds continuing, highs near 17 C.
THURSDAY could bring a pleasant break from the unsettled weather, but it seems likely to return and push some rain at least into western counties by Friday. The near Atlantic will become very windy from a southerly gale but this may stay offshore and blow more towards Iceland eventually, as swelling high pressure over Scandinavia late next week may be gradually taking more charge of the situation and setting up a more settled SE'ly weather pattern by the following weekend and towards mid-month.
We enjoyed a third ideal day in a row here with sunshine and highs in the lower 20s on Friday the first. The remnant low of Nicole raced across New England today and brought rainfalls of 3 to 6 inches to many parts of the northeast U.S. but it has begun to clear with much cooler weather setting in there tonight (local time). That low is now in New Brunswick, Canada and heading east on pace to arrive in some form in Ireland by about Monday night or Tuesday.
Please watch the ongoing thunderstorm and weather report threads here for new ideas about storm development later today as it's very likely yours truly will be asleep (again). :cool:0 -

Have posted a separate thread to alert boards readers in general, severe storm complex on radar and from report on this forum, covering counties Limerick and Cork especially around Mallow by 1215-1230, a line of storms that may contain large hail and torrential downpours, and has reportedly frequent lightning strikes, moving northeast 20-30 mph, towards a line from Limerick City to Mallow to near Cork. It may move just north of Cork but people around that city should be on alert too.
With this severe storm there is a slight risk of a weak tornado developing or more likely some funnel clouds being sighted. Hail is probably a more likely risk, and there could be torrential rains locally.
Will advise on further developments and eventual dissipation as this line may hold together well into the "midlands" counties.0 -

TODAY ... Cloudy with a few bright or even sunny intervals, although rather misty near the south and west coasts much of the day ... any low cloud and light rain around this morning may break up for a while, then showers will redevelop although nothing too heavy seems likely (2-4 mms here and there) ... winds rather light SE to S, veering more SW to W later on ... breezier in the north by this evening. Highs today about 15-16 C.
TONIGHT ... Cloudy with a few clear intervals, mist returning and becoming foggy before morning ... a few light showers with some stronger SW winds developing towards morning ... lows 7-10 C.
MONDAY ... cloudy with a few sunny breaks, blustery showers developing, possibly becoming heavy or even locally severe by mid-day and afternoon, winds SW 30-45 mph with some higher gusts ... highs 15-17 C. Rainfalls on average 15-25 mms.
TUESDAY ... windy at times with squally showers, passing quickly, brighter intervals mixed in, winds SW 25-45 mph, lows near 7 C and highs near 16 C.
WEDNESDAY ... cloudy with some breaks, more showers in a moderate SW wind, backing at times to southerly, then falling off by evening to light. Lows near 8 C and highs near 15 C.
THURSDAY ... mainly dry with variable cloud, some chance of rain near the west coast, winds moderate SE to S but very strong to gale force (50-55 mph) gusts near the west coast by late in the day from a deep ocean storm out around 20 W ... lows near 6 C and highs near 16 C.
FRIDAY ... continuing breezy or locally windy in the west, intervals of light rain perhaps confined to western half and south coast, lows near 7 C and highs near 15 C. Winds backing to SSE 20-40 mph.
WEEKEND ... cloudy with some light rain or drizzle, tending to be drier in some east central counties, a rather cool E-SE wind developing, lows near 7 C and highs near 14 C.
This pattern may evolve gradually into an easterly backing to northeast, with rather dry conditions generally but the chance of isolated brief showers from the Irish Sea near the east coast at times. There may eventually be some frost from this pattern mid-month.
We enjoyed yet another fine day here on Saturday, with a high of about 19 or 20 C. The weather across North America is generally closer to average than most of the past few weeks, staying hot and dry in the southwest, and rather chilly near the Great Lakes. The tropical scene has gone rather quiet with a slight chance of a named storm mid-week near the Virgin Islands.0 -

UPDATE _ Sunday, 2:00 p.m.
_______________________
Just an advance ALERT for strong winds and squally showers due to arrive in the west on Monday around early to mid-afternoon, then across the country quite rapidly as the system is moving at about 50-60 mph (it is currently out around 30 deg W but well out ahead of the parent low which was the extratropical hybrid from Nicole).
Backing up to the rest of today, it should remain dry in eastern Ireland while the west continues to see scattered but rather light showers. This activity will tend to die out after sunset and the overnight lows may be a little more chilly than most recent nights, in the 4-7 C range, except closer to the west coast where a breeze will keep readings closer to 9-10 C.
Monday should start out with just variable cloud and isolated showers, with a moderate S to SW wind developing. Then the aforementioned frontal system will come racing in with a significant period of wind and rain, and we'll be watching for any local storm development with this. Highs on Monday should average
16-17 C.0
