Your chances of seeing snow with Canada void of cold air and a trough over the pacific west is extremely low odds here in the east as we've seen, It does look better as we roll forward.
The one late week fits the bill as a SWFE with that gradient look moving thru the upper ohio valley, The next two on the 06z GFS look more Miller B'ish coming out of the lower tennessee valley and off the New England coast under SNE into the GOM.
I think where you have the map totals up here are very reasonable, Your bringing in moisture off the atlantic with some warmer air too, So that right there is more of a IP signal and even some ZR.
Euro hit quite a few spots up here hard too, One thing i will say, There's going to be some pretty large model bust each side of the totals one way or another.
