Actually, cut snowfall in half from 12z for mby, BWI, DCA and even SBY.

Height lines are not as far north at 72hrs and trough up north and little east of 12z

Maybe, but the surface map looks like the Gfs and unlike other medium range models. Just sayin'.

Posted that 2 hours ago. He's a copy cat! Lol

Appears to be a kicker coming down near the Dakotas and the Gfs has it further north into Canada, the Gem further south, and the Ukie the furthest south. It's killing the ridge orientation.

Ukie on the road to a total miss unless that trough has a miracle.

You could see it coming instead height lines all backing up.

Closer

Look at those height lines rising and everything backingvup

84hrs vs last runs

Icon definitely further west with the western lobe of the northern trough at 72 vs 6z run fwiw.
