12z Euro AI is a CLASSIC Mid Atlantic snowstorm. Primary low drives into Tennessee, then hands of everything to the coastal quickly and cleanly. 8" - 12" cold powder, weekend snow.
Yea 12z Thursday is my go/no go for this event. I'd much rather deal with suppression than worrying about something cutting. With such a fresh, strong push of cold air coming I don't think we have to worry about this cutting too much this time.
Earlier this month, Tomer Burg (PolarWx) on Twitter posited that DC - NYC could see something on the order of ~20" for the month of January and people laughed at him. He might be right.
12z GFS is a reasonable "fail" scenario where the shortwave doesn't eject cleanly -AND- the confluence to the north is stronger. Even with that in mind, it looks like a solid plowable to warning level snowfall for the entire subforum with no temp issue - and it's on a weekend.
It's absolutely beautiful. CAD Signature all the way to interior South Carolina, moisture laden storm, banana high from Quebec down to Texas. This is perfect.
