Met Office/BBC are forecasting a wet start to the day tomorrow, and a drier interlude before light snow, heavy at times after 5pm tomorrow, and intermittently through the night. This is of course on their 5 day forecast, but it has been consistently shown as at least light snow, and if there is a drying up period after the wet start this could be promising.
Conditions look very favourable if we get the precipitation, with below 0 dewpoints shown from the earlier 6z GFS, marginality isn't an issue, it's just hoping we get some sort of organisation towards us of precipitation.
