The wild card is that deep layer easterly fetch....you don't need insane mid level dynamics....Dec 1992 tucked wayyyyy in near LI, occluded, and still kicked back 3-4" of QPF.
At least with a hugger, there is less likely to be a subby hole west of the CF with that deep easterly fetch...may not even need the deformation, which would be way back west.
24 hours...okay.
Post the support for 48 hours of mod to heavy snow...that should be widespread 24"+ relatively evenly distributed over the course of 2 days.
I agree, John...those 36-48 hr depictions never work out. The bulk of this impact should be within a 24 hr period, and anything beyond is nuisance variety.
