Lol I've seen we've digressed into talking about '58 here. Just take your 16" inches and be happy. .... clearly too many weenies for breakfast. Nothing about this says Hecs, this is modeled as a reasonable Mecs. I dont think the low is deep enough. No wonder these storms always fall short of expectations when the expectations rise of the granddaddy of all PA blizzards-- what do you expect.
I think the Para shows a nice solution however I think the gradient will be further south and tighter. Realistically there will be some dry slotting and probably a crust of sleet at some point. Somebody will probably see 20 to 22" out of this but you'd have to be color blind to see 50" on any of these maps!!
