2 Maps Showing What Your Chances are for a White Christmas:

NOAA has dished up the above map to show us the historical probability of having a White Christmas.  The whiter the color, the more likely the location is to have a White Christmas.

Accuweather has delivered something a bit more specific to this year, but you have to take this with a grain of salt or two since Xmas is still 10 days out.
