The big story this morning is obviously the potential significant snowfall for the coastal locations of the northern Mid Atlantic. I will be diving into my thoughts on the evolution of this storm, and what to look for in the next 24 hours in guidance in a minute.

Over the past several weeks I have been strongly hinting at a cold start to December. The various indicators I’ve been looking at to make these statements include the Stratospheric anomalies of late, the development of the MJO state, and the growth of snow cover over much of Alaska and northwestern Canada.

A continued theme from the December forecast, looks like model guidance is strongly jumping onto the idea of a very cold start to December for much of the CONUS. We have a strong PNA ridge developing for the start of December, but also some other interesting features. A strong upper low over California is expected [...]
