Winter '11 / '12 - North Atlantic Oscillation - About Face

NAO dips below zero for the first time in 55 days (-0.082 on 17-NOV-11).

Question now is will it last and if it does...how strong will it be?  Current GooFuS and its ensemble forecasts hold out little hope...

Arctic Oscillation (AO) forecasts are another...more promising story...

For many NEWxSFC forecast stations...a negative AO plays a bigger role than a negative NAO for contest-worthy storms.
