Approximate cutoff between what will largely fall as rain vs mostly snow (assuming the NAM's temp profiles are correct) Within the snow zone, a coating to half an inch is possible with a small chance of more if banding develops.
850 temps at onset favor snow West of 85 and rain East. Doesn't push the cold air East until after most of the moisture has exited. Just something to watch Tommorow morning
I think he could very well be right, if as usual cold air takes longer than expected to bleed over the mountains. However,I do feel we could overcome with decent rates and get a coating or so as far SE as RAH
RGEM tilts neutral too late and too far north so it's a late bloomer, best precip over VA by the time the cold air arrives. Axis of best dynamics over DC
Timing will be key too, if we can get that band of WAA moisture to set up early enough in the AM it will be easier for temps to crash and snow to start accumulating
The things is, we're in a great spot to thread the needle in terms of model spread. It's just frustrating we have no wiggle room one way or the other and it's trended that way for a days now (even as track/vortex evolution has trended favorable)
My biggest concern is the trend towards the low popping off the coast further north, in a more miller B fashion. This would allow more warm air to migrate inland and best dynamics to stay north of the VA border until the low starts moving more NE. At that point it becomes a cold chasing moisture kind of situation
