The 00z Euro and Ukie are significantly different and colder from the GFS and both bring good snows to the area. 12z GFS has trended more south and wave is weaker which is good if you want snow.
He must be talking about another GFS model in an alternate universe because the one that I was tracking with this storm put on an embarrassing display and as usual caved to the other models late in the game.
What eastward extreme? Parts of NYC metro got a foot of snow when that POS model was only giving a snowstorm to the Canadian Maritimes 48 hours before game time. It was absolutely God awful with this storm. One of the worst performances ever.
