The air mass is not a cold one. Its cold this morning because it was perfect radiational cooling conditions overnight.
If the track were perfect, as guidance was suggesting over the past day or 2, then it might work out for eastern areas. Trends across guidance is a closer to the coast track, and with no real source of cold air, it comes down to dynamics. Best dynamics now appear to be coincident with the areas that tend to do well in marginal setups- inland.elevated, and less low level warming with the coastal. If this were not such a fast mover, then even with the further north/west track there might be some decent snow for eastern areas as the lower levels cool on the backside. That is not the case, however. Also a HP to the N or NW would change the outcome, but that also is not the case.
Now, continue whinging.
