Guys no mention at all of the west or midlands in the forecast. Shall we be sunbathing?

This is the forecast that I would derive from the current model suite, take this more as a map interpretation than an actual forecast update from me (so not to be cross-posted in forecast thread, if this looks to be on track by morning I may have wording like this in the morning update):

UPDATE __ Friday 23 Feb 2018 __ 9:30 p.m.

Latest guidance continues to emphasize potential for heavy snowfall as well as record cold temperatures for this time of year. The full measure of cold arrives in the east on Monday afternoon and quickly overspreads the country, so temperatures will be falling sharply on Monday night to reach about -7 C inland, -3 C east coast by Tuesday morning. Scattered outbreaks of light snow at first will turn to streamers of heavy snow impacting mostly central Leinster on Tuesday with 5-10 cm potential. Temperatures will struggle to reach 1 or 2 C near the east coast and -1 or zero inland on Tuesday. Tuesday night may be even colder with some lows approaching -10 C in the north and west, -5 C east and south. Heavier snow will develop over larger areas by Wednesday and will continue at least intermittently through Thursday, Friday and Saturday as winds back into the northeast and become quite strong at times (50-80 km/hr). Each day has the potential for 10-20 cm snowfalls in some parts of Leinster and Munster as well as east Ulster, more like 5-10 cm for most of Connacht and Donegal. A few places could have much less snow near the west coast but this is not a certainty. Temperatures during this snowy episode will tend to remain in a narrow range of -1 to -4 C during the snow but if there are clear intervals at night could fall to -10 C or lower. The net effect of the intermittent outbreaks of snow will probably be a peak cover of about 20 to 40 cm over some parts of the inland southeast and Dublin-Meath, and 30 to 50 cm over parts of the east-facing slopes in south Dublin and Wicklow. Combined with the winds and blowing snow, there could be blizzard conditions especially in open areas of central Leinster.
