You could come to Okla. where you can have a white, cold Christmas, or a nice warm (well, like 65-70) sunny Christmas (and a lot of Christmases with weather inbetween those examples. Or you could go to S. Tex. where Christmas day was a hot 85 in 1964 or have a cold (32 degree), cloudy, drizzly day (1974) which I experienced those two years. I grew up Sw of San Antonio and most Christmases were somewhere in between.
Probably any of the above, but then you have to remember that you also have to put up with the summers in those places.
