You got that right. Im not sure if it's right but I hope so. The GFS tends to be stubborn when it locks onto something but then eventually caves to other guidance. It did that with the last storm.
The farther north and west you are the better chance you have with this one. I'm 20 miles north of 84 so hoping for some snow after initial rain, then sleet/ZR. We will see.
The front and wave or waves have plenty of moisture associated with this setup. The big question with this is how quickly the cold air pushes south and what precip type is the result and where. That is complicated and has not been resolved yet.
That depends on where you live. Im north of 84 and it gives me plenty of ZR and sleet. Like I said its a battle and a long way to go on this one but I wouldn't be surprised if models continue to trend colder.
That artic high means business and models starting to pick up on it. Ukie was the colder outlier but ICON FWIW has trended significantly south and GFS also. GFS verbatim gives me a little rain to sleet to heavy snow. It's a battle and we are in the battle zone.
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.
