Strictly from a White Christmas standpoint, there is a little vort that slides just to our south on the 24th. Something like that on the heels of the Arctic front could do it.
This is really good. You are going to have to post it multiple times this winter. I never really considered the wind, but it does physically make sense given latent heating.

(and now that I notice it, it is kind of like an in-browser pop-up. Maybe you have it disabled?)
