Weekend storm: Glancing blow or blizzard?


The images above show the latest simulations for the potential weekend (extending into Monday for the European model) storm from the most recent operational versions of the GFS (American) and European computer models. The GFS model (run this afternoon) indicates very light snow Christmas afternoon and evening with the modest storm mostly going out to sea. The European model (run this morning) simulates the same system as a full-fledged blizzard Sunday into Monday.

Our thoughts about the most likely scenario for this storm haven't changed from our post earlier today - but I just thought I'd post these images because the differences are so striking.

Nobody said forecasting snow in the mid-Atlantic was easy...
