NAM still had this thing running off the coast of SC last night IIRC.
GFS has nailed it from the beginning. I want to see the 19 inches it has repeatedly shown me I am going to get, so I am hugging it.
I have been watching Mid Atlantic snowstorms for only 10 years (way less than some other posters) and I have never seen it not happen this way.
NW areas won’t get as much QPF, but will be colder and thus get more snow out of the QPF they do get.
