Might as well put up a separate thread for this "event".
A cold front will move southeastwards across the country overnight Wednesday and into Thursday morning. As it does so it should readily turn to snow over land, however its intensity will most likely decrease the further southeastwards it moves.
ECM sounding show fairly good snow parameters (i.e. sub-zero through the lower levels and saturation up to near -10 C, which is just about getting into the optimum dendritic-growth zone). The cloud layer will not be very deep so precipitation should be fairly light, but inland northwest and north midlands should see the best intensity, with areas into Leinster also seeing something in the way of snowfall.
It will be during the night and it will pass through fairly quickly, but it is worth at least keeping an interested eye on.
