I wrote about the SSW before Christmas over at DailyKos. I'm following some of the experts on twitter & elsewhere and also doing my own analysis of the prognostic tools. There's going to be a major snowstorm this weekend that goes from the plains through the midwest into New England, then a series of cold air outbreaks will follow.
The forecast I made before Christmas is verifying. Obviously, long term forecasts are generalized, but it's verifying for the reasons I gave. Judah Cohen should have a new blog post up soon on his forecast.
