I think all this flip flopping we're seeing with the models is them trying to simulate where the heaviest banding sets up, rather than how far the warm nose edges in.
Given all the trends today so far, there's little change in temps aloft. For nearly all of us that we stay below freezing up to 700mb until the wee hours of the storm when precip is winding down.
All these jumps north/south are figuring out the heaviest bands. Lift vs subsidence. Someone's gonna be sitting under a weenie band, and someone 10 miles north or south is going to be screwed.
