Tonight, Sunday, Monday
Higher ground of the northwest -- some snow showers by the early hours of the morning with some accumulations locally. Sleet, hail to low levels.
Hi all, been a while
This has been developing gradually over the last few days and finally the first real blast of winter is nearly upon us. The first incursion is tonight but will be interrupted on Monday and Tuesday by slightly milder air.
From Tuesday evening, a long with brisk winds, a polar airmass will become established in the west and quickly spread countrywide overnight a long with heavy showers from the northwest. Initially these will be mostly rain and hail but through the night that quickly changes and they turn to sleet/snow countrywide by morning driven right across the country on a very strong or gale force wind. See this thread http://www.boards.ie/vbulletin/showt...p?t=2057338060
A long with the risk of snow - frost and ice will become harsher in the midlands and east. Frost not an issue on west coasts due to the strong onshore wind.
It's pretty much certain that this set up lasts from Tuesday evening until at least Friday night. Snow accumulations are still a bit early to speculate but in the northwest and north I think it is very likely to low levels particularly overnight.
One thing you will really notice is the wind chill which will be well below freezing throughout even though temperatures will be around 1 - 6c nationally.
Not pleasant to be out in but it may be very pleasant to look at
