Arctic oscillation picking up where it left off last winter? Literally? And the NAO is going strongly negative. Very impressive actually.
This is a short blog entry tonight. I need to stress that this current set up is strongly related to major northeast storms. Only difference this year is that we are in a La Nina pattern which typically provides much less moisture than El Nino's.
My point is that if a "surprise" snowstorm pops up on the models with only a two or three day warning don't let it catch you off guard. Nonetheless, it seems obvious the cold air is one it's way.
