Consider that the ground wasn't froze prior to the snow and that as soon as the wind stops blowing strong the temps are going to go up, I thin the snow melts wherever it is.
When the Sun comes up it will only speed up the process (as it does here in The Ozarks)
I see a Christmas with White only in the Northern Shadows of the Northern counties.

But watch those turn Hollers down there....I bet they stay frosty a good while.
