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.
