I appreciate the doubtful honesty, skinsfan. I am a meteorology student in North Carolina. Just based off my own analysis and observations, coupled with those of older, wiser forecasters, I think there's a reasonably good chance of snow for Christmas. You're absolutely right; we still struggle with predictions a week ahead of time, and even in some cases 24 hours beforehand. But, some in the meteorological community (OK, consisting of my own hand-picked members) have a hunch this Christmas day storm will be a snowy force to contend with.
HAHA! Yes, I feel the stars will align with the Skins notching a W and the full moon appearing on Sunday, then the "Christmas Snow Storm of 2007." You apparently don't need Miss Cleo to figure this out.
Hmm, you are realing pushing the limits of predictability with the question about weather conditions for the Dallas game. I will be at FedEx as well, so let's hope for 70s and sun???
