FWIW, 0z GFS op says favored snow spots see a little flakage on the back side of the LP passage. Unfortunately verbatim, it wont happen during the storm as 850's are toast, and precip is gone by the time they become favorable. as is the norm, I'd think that during more intense precip rates, that column might just support catpaws in lucky spots.
Regardless the outcome, its still fun to be taking about a nice system like this. Pattern is close, and were it 4 weeks later, i'd be moderately giddy.
