The moment MattyH has been looking forward too :S
Snow risk map for tommorow, based on ECMWF, GFS, WRF, EURO4 models. Variety of parameters used, including soundings. Probability is for 0:01 Tuesday to 23:59 Tuesday for snow to fall at some point during the day.
Models indicate an extremely high risk of snow for NW parts of N ireland, and Ireland in general. I think the front will contain a bit of snow on it for these parts too.
Note, the map is not intended to be a guide for the hills, this is useful for urban sites, or rural sites below about 200m. Cairngorns and higher parts of the pennines will have close to a 100% chance of seeing snow for instance rather than the 50:50 odds indicated.
Feel free to copy this map wherever, but please credit me :)
Few adendums:
For yorkshire, there is a higher probability of snow in central yorkshire than indicated here (concentric contours would be appropiate); the resolution is perhaps not high enough to show it; York for instance probably has closer to a 50% chance of seeing snow.
The probability of snow in wales dramatically shifts from north to south, there would be a dividing line perhaps half way down wales where the probability of snow massivly increases to the north of that.
