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).
