12Z GFS, low transfer is slower than the rgem so more frz gets into PA as the column does not do as well as it does on the sleetly rgem. It also starts the precip quite a bit earlier in the LSV. Mix around by 4Pm Sat.
Entire state of PA has snow of varying intensities on WED (not Tue) as the Icon's depiction is a good 24 hours behind. Easters win this one as the low pulls away Wed evening.
