Leading edge snow is always a possibility, but in my eyes pointless. Obviously with -3/-4 upper air profiles in place, the chance of widespread frontal snow is there which doesn't necessarily require the coldest uppers. But in my eyes this is turning into a cold snap rather than a cold spell, according to the GFS
If it wasn't for such a mild December, this sort of cold spell wouldn't even be exciting 90% of the members on the board. Poor effort, but good reload potential from the east, I guess.
Im more looking forward to an anti-cyclonic spell, some frosts & sunny days would be nice!
