When was our last White Christmas, and when could we see one again?
Our last White Christmas (as determined at SEATAC) was 2008, when the airport measured 4" of snow on the ground. 1" is needed for a Christmas Day to be considered 'officially white'. Weather statistics suggest Seattle has a 7-8% chance of a white Christmas in any given year, while Portland has only a 1% chance, Spokane a 70% chance, and Fairbanks Alaska has almost a 100% chance!
