Parts of the midlands reasonably likely to get a surprise on Wednesday evening with 850hpa temps inland hovering just under -4c and closer to the surface than usual with the 500hpa GP heights. This translates to temperatures at ground level 0 - 2c away from windward coastal counties. Dew points hovering between 0 and 1c.



Still a bit too far out for nitty gritty details but something to keep an eye on.

Certainly scope for sleet and wet snow to lower levels there.

At the moment Wednesday evening seems the best chance.

Well going by the ECM Weds is just a practice run for sleet/ snow forecasting. Sat looks a possibility also although a fair amount of uncertainty still . ECM currently showing the passage of a front moving into cold airs. Could be a very wintry day for large parts of the country. Temperatures at the moment look colder on Sat with large areas less than 5C and lower for much of the day.

ECM more or less dropped the widespread sleet / snow for Sat but ICON now showing it and more so in the Western half of the country . ARPEGE showing rain / sleet in parts of the country. Bit to go yet.

Models backed off anything wintry on Sat, and lessened the amount of rainfall with the slow approaching weakened occluded front mostly keeping the rain on the Western half of the country, amounts small.

Fri night into Sat morning very cold for large parts of the country with a sharp frost.

Cloud clearing all the time here in Kerry, swept away by a nice fresh NNE'ly breeze. Temperature watch tonight , a proper widespread freeze for most under clear skies. Looks fairly dry for the rest of the day apart from a few light showers maybe in Northern counties. Winds slacking off later today.

ECM showing some heavy rain around Weds into Thurs for the SE and along Southern fringes. Showing very high totals for the SE .

Showing very high totals for the SE up to next Sunday but that chart is better in the FI thread for now.

ECM backed off a bit from the high totals in the SE but other models showing a lot of precipitation by Sat /Sun ( a bit over the 120hrs )

Other models might moderate the amounts in the next few runs like the ECM ?

LP's certainly in charge and after the weekend also.

Slow moving system producing a lot of rainfall in S and SE counties, Yellow warnings in place up to Thurs 12.00 but rainfall doesn't stop there.

Waterford seems to be in the cross hairs for the heaviest rainfall over the coming days.
