Just to add, one thing I noticed with a lot of regualrity over the last two winters is that the forecasts never picked up on some of the heavy falls of snow (few hours worth of snow at a time) so definitely nowcasting as some have already suggested, is most certainly the case.
All the stresses of model watching over the past two weeks are now about to come to fruition. Time to sit back, relax, enjoy and watch events unfold.
