UPDATE _ Tuesday, 4:30 p.m.
________________________

Heavier rain is developing across much of counties (north) Clare, Galway, Mayo and Sligo with potential for 25 mms and local flooding. This may extend somewhat beyond these counties into adjacent parts of Roscommon, Leitrim, Longford, Westmeath and Offaly, but the heaviest rains appear to be near Galway city.

For regions further east, the risk of heavy rain depends on whether the system remains this active through the late evening and overnight. Will update on this around 8 p.m.

UPDATE _ Tuesday, 7:45 p.m.
__________________________

The trend seems to be towards gradual weakening of the rainfall now, if anything the southwest and south central counties have more significant activity, as well as parts of Mayo, but the southeast is fairly dry at present. Eventually, you might expect the rain to move further east in general, but weakening further especially after midnight. This should all end in a widespread mist or locally dense fog by morning, with further light rain or drizzle mainly confined to the east during the first half of the day, then some gradual clearing from the west.

I will speculate about next week in the Wednesday morning forecast, as I don't place a lot of confidence in the guidance past this weekend yet.

UPDATE _ Wed 15th, 7:45 pm

It would appear that the good people of Waterford (as well as the bad people there, if any) have angered the gods of thunder, but otherwise, the situation is all quiet for most parts of Ireland, as the advertised weak disturbance forms up west of Donegal and prepares to push in its cloud and light scattered showers for tomorrow. The thundery showers around Waterford and Dungarvan (yes, I have an atlas) may also affect Wexford, but if the showers try to move much further inland I suspect they will quickly die out over the hills in south Wicklow. And if not, nobody will be up there after dark, right? ... Friday still looks quite active in southeast England if anyone has a flight booked into London, there could be delays or at least don't order lunch until you're on the ground.

Please note, a new forecast will be posted soon, but I have only had time this evening (my time) to check the new model run and situation rather briefly, and I don't see anything too different from the existing forecast posted yesterday (see above three posts or so) ... so my apologies, but I am pretty sure that I will just be repeating that forecast in about 30 minutes or so. (having some vehicle repairs done outside my home and this has taken longer than expected, back soon).

The main area of rain has retreated into the Irish Sea but if you're on the beach you may see a few raindrops ... that's how close to land it appears to be on radar.

More very soon. :cool:

TODAY may start out bright in some eastern counties, while a misty, damp overcast regime spreads into the northwest and tries to take over the south coast as well, although much of that rain has come and gone for the time being. More may develop but I am not convinced that the south will get into any prolonged or heavier rain so much as perhaps the northwest and later Ulster ... things are complicated by how much of the Atlantic system gets pulled into the spinning remnants of the major U.K. storm system which still has lots of moisture and energy and is heading northwest across Scotland. So as you can see, I am hedging because frankly, the cloud signature looks rather like the rainfall potential is trying to merge the two systems over Ulster later today into tonight. In any case, it almost certainly won't be a dry day for too many and if rain does come in any measurable amounts there will probably be a tendency to hill fog and mist later on as well. Highs throughout should be near 17 C. Watch for updates though, possibly from me if I stay up all night watching the golf as is my desire (currently it is 9:30 pm where I reside far from the hurly burly so to speak).

TONIGHT (meaning Saturday night in Ireland, I have to refocus) will continue cloudy and damp with perhaps a final burst of moderate rain from the dying Atlantic wave as it gets pulled into the circulation of the stronger low to the north. Winds will start to pick up from the WNW at 20-30 mph by morning, and lows should reach about 10 or 11 C.

SUNDAY is looking quite windy still, although there has been a downgrade due rather perversely to the strength of the low taking it on a long westward journey to the north of Ireland. This will make the wind direction more westerly than the previously advertised NW'ly although it could start off that way in the morning. Cloud amounts will be quite variable as the cloud should tend to form long streaks of low-based strato-cumulus that will have sunny "lanes" between them. Also some of the clouds will boil up high enough to drop a sharp, five to ten minute shower here and there. If you have higher ground to your southeast or east, you are more likely to get rain than other people (assuming you live in Ireland, that is). Highs will be about 18 C.

MONDAY could feature hours of sunshine, like perhaps one or two or even three for some lucky folk, then another storm will be arriving off the southwest coast and spreading its brand new load of cloud across the land, followed by a steady downpour by evening. Highs could reach 20 C in the sunny mid-day intervals.

TUESDAY will become wet in all areas for a time, with thundery downpours possible, and highs near 18 C. At the present indication, winds should not be much of an issue. The low is basically heading straight for southeast Ireland and into the Irish Sea.

WEDNESDAY is likely to be showery too but there should be some clearing by afternoon although possibly not that much sunshine. Highs will reach about 20 or 21 C.

THURSDAY yet another low comes calling, I was getting dizzy looking at them all but I think it is the remnants of the U.K. low returning from the leisurely tour of the central Atlantic. Or perhaps that will be Friday's low. In any case, if this is barbecue summer, I hope your barbecue came with a substantial umbrella.

However, you can't knock the terrific weather you had already, there is that.

If you still recall any of that.

Updates may follow, if there is anything to report. Turnberry is looking somewhat on the edge of the worst weather for Scotland but eventually I think a driving rain will test the players (ah great).

Tom Watson would still be very competitive if he had full confidence in his short putting. He may actually benefit from the wind and rain (if it proves to be a big factor) because everyone else will be having trouble with their putting as well. John Daly might do well, hard to say if he's aware of the weather that much.

Looking at the radar, I would say 3-5 mm rainfalls likely across much of Mayo and Galway, 2-3 mms across Clare and Kerry into Cork, but perhaps only 1-2 for rest of Ireland unless far Northern Ireland and Donegal get into the backwash from the main low later on. Not a terrible day, too bad it's a weekend though.

UPDATE _ Saturday, 8:45 p.m.
________________________

Some rather heavy bursts of rain showing up now in central Ireland in connection with a weak wave moving east and likely to drift more south of due east later, so would look for a rainy evening in parts of Offaly, Laois, Kildare, Carlow, Wicklow ... 5-7 mms of rain seems possible with this. Other regions will have more like a gentle drizzle or misty situation.

Well, they certainly got lucky with the weather at Turnberry, it seemed from the radar that the golf course was between two lines of heavy showers, and you could certainly see the showers just to the north on some of the views, tomorrow I think they will have a 'soft" day and we all know what that means -- or do we?

Perhaps to add a dimension to this thread, I will try to remember to post my mid-day weather conditions near Vancouver, Canada, on these evening updates. Today so far, sunny and quite warm, about 26 C, a weak sea breeze is reaching my location (barely) and it was a bit hotter yesterday, we have had a weak, dry cold front drift through this morning. I know it sounds great, but we could use some rain, everything bone dry around this part of the world now.

TODAY will start out cloudy with widespread light showery rain but gradual brightening if not clearing can be expected as winds pick up by mid-day to about 20-30 mph from the west. A few more scattered showers, possibly one or two briefly thundery, will develop in the afternoon. Highs will be near 18 C.

TONIGHT will see somewhat stronger winds near the northwest coast (30-40 mph) and continued strong westerly breezes elsewhere, but showers may die off to more of a drizzly mist or fog on hills, as some eastern and southern counties get a spot of clearing and lows generally fall to about 9 or 10 C.

MONDAY will see further gusty winds and showers across Donegal and parts of NI but this will be confined to the north coasts mostly, then a pleasant mid-day interval should bring some sunshine and fairly warm temperatures near 20 C in many parts of Ireland, to be followed rather quickly by increasing cloud as winds back to the south then southeast. Rain will follow into the southwest at least by evening.

TUESDAY is now looking even wetter than previously advertised, as a strong low swerves north along the west coast. This will create a period of strong SE winds on the south coast reaching up to Dublin by mid-morning and spreading out across inland areas, with heavy rain at times, or thundershowers. There is potential for another 20-30 mms in this storm. Winds could gust to 40 mph or higher on the coast. Morning lows will be 13 to 15 C and afternoon highs not much different at 17 to 19 C.

WEDNESDAY should be improved as skies clear gradually after some morning showers, and highs reach 20 C.

THURSDAY and FRIDAY are likely to be showery and reasonably warm near 18 or 19 C.

Updates may follow ...

Enjoy the golf, especially if you're playing. I had to laugh when they started talking about "Old Tom Watson," mostly because I am three months his elder, if perhaps three strokes his senior also, per hole.

UPDATE _ Sunday, 2 p.m.
______________________

I would say that unless you've already had your barbeque in Dublin at mid-day, the chances are fairly slim that it will be a rain-free period, as the frequency of showers will increase as they are likely to do across much of eastern Ireland this afternoon ... a renewed wave of energy is rotating around the larger storm well to the north of Ireland (which is heading west itself) and this can be seen on radar as a knot of heavier showers, some of which could be briefly thundery, around northeast Galway county, a feature that will probably hold together as it moves steadily east and perhaps a little south over the rest of the daylight hours today. Counties ahead of this feature such as Longford, Westmeath, Meath, Kildare and Dublin may see some fairly heavy downpours later on and accumulate 5-8 mms of rain.

Further south the showers may be more widely scattered and not as heavy, and a few sunny intervals are possible. And further north, it will be bright and breezy at times with the risk of a heavy shower.

__________________________

TODAY will feature some sunny intervals for the south and east in particular, but it will stay rather breezy across the north with scattered showers. Meanwhile, cloud will be massing off the south coast for a determined push northward in the afternoon, ahead of a storm due to arrive by morning. Some rain could reach the south coast and the southwest by evening.

Highs today will reach about 20 C in the east, 18 C across the south and west coastal districts, and more like 16 or 17 C in most of Ulster.

TONIGHT will see cloud and then rain moving in from the south, to cover most of Ireland before morning. Winds will pick up rapidly from the ESE at about 30-40 mph offshore and 20-30 mph on land. Lows will be near 12 C.

TUESDAY will start with a period of heavy rain with some risk of thunder, as the strongest winds move slowly north towards Ulster by afternoon. There could be some late improvements in the south and southwest, but for many regions, much of the day will be wet and windy. Highs will reach about 18 C.

WEDNESDAY will be more variable with a moderate S to SW wind and some showers or thundershowers redeveloping. Lows of about 14 C will be followed by highs near 21 C.

THURSDAY will be cloudy with occasional showers or longer periods of rain, and rather strong SW to W winds arriving later, basically the remnants of the weekend U.K. storm making a loop around and returning from the west. The temperature range will be about 12 to 18 C.

FRIDAY looks partly cloudy, breezy and rather cool with highs near 17 C.

NEXT WEEKEND from this perspective looks somewhat encouraging with weak ridging advertised, so possibly a dry and reasonably warm scenario with limited shower potential. We'll see how long that lasts the "weekend test."

Wednesday, 22 July, 2009
__________________________

Briefly, TODAY will start out partly cloudy and dry for most, but heavy showers and the odd thundershower may develop in the afternoon especially west and north, highs 20 - 22 C.

TONIGHT cloudy with clear periods, lows near 11 C.

THURSDAY cloudy with showers, periods of rain developing, highs 17-19 C.

FRIDAY, partly cloudy, breezy, cooler, 17 C.

SATURDAY, pleasant, some sun, highs near 19 C.

SUNDAY, rain spreading across most regions, heavy at times west, 18 C.

Back in about a week, gone fishing.

Hello, I just popped in to say thanks to Darkman2 for taking on the forecasting for the past week ... we have had some extreme heat here in British Columbia with highs the past few days up around 35 C, even higher in a few spots, and not the usual low humidity we get with our heat waves, but dew points close to 20 C.

This is all contributing to our decision to add on a few more days of "time away" because the heat is more tolerable near a cool mountain lake than in the city where we live. Just happened to have access to the internet "tonight" (it is past midnight but still about 27 C outside). I have not been following the weather you've been having, but I did scroll through the forecasts, and it seems that we should be sharing this heat a little more fairly.

At least, I am in favour of this and will have a word with the weather gods if they materialize at any point, possibly we could do a trade or at least a blend.

So, if Darkman2 wouldn't mind holding the fort for a couple more days, I hope to have something posted for the weekend. -- MTC

The horror, the horror ... as the lows just keep on coming, riding a depressed jet stream across the Atlantic and dumping their load of moisture on Ireland.

TODAY will see bouts of heavy rain spreading gradually from southwest to northeast, and eventually most places should record about 25 mms or an inch of rain, although perhaps a little less in some eastern sections. If it's not already raining, it will be by about 0900 or so. A rather strong SE to S wind of about 20-35 mph will add a somewhat raw feel as highs are likely to stall at about 16 or 17 C.

TONIGHT could see some clearing especially in the western half of Ireland although cloud may linger well after the rain lets up. Lows will be about 9 or 10 C in a 20-30 mph westerly wind.

SATURDAY could have some brighter intervals to start, then another period of heavy showers, some thundery, will develop from west to east around late morning to mid-day. Highs will reach 17 C or so, with a westerly breeze of 15-25 mph (stronger at times off the northwest coast).

SUNDAY looks to be cloudy with intermittent light rain or drizzle, and possibly a period of heavier rain too, more about that as we get closer to the event. Lows will be near 11 C and highs about 15 to 17 C.

MONDAY should continue cloudy with occasional rain, rather humid as slightly warmer air arrives, so possibly becoming foggy at times near the south coast especially, and temperatures generally 12 to 19 C.

TUESDAY may bring some heavy showers as a rather strong frontal system develops near the southeast coast.

Anyone wanting heat and sunshine, head this way (there may be closer options), as weather patterns seem locked in for at least another week or so; after that, I could mention some faint hope of warmer and sunnier conditions for Ireland, at least warmer.
