Updated Average White Christmas Map in HD!
I blogged last year that NCDC had produced an updated version of the U.S. Average White Christmas Map. This year I am pleased to bring our HD version to you (click to enlarge). Please make sure you are using the new map this season.

This new NCDC data covers the climatological period from 1980-2012 instead of 1960-1990, so this is a big update. Last year I talked about some of the changes, and showed a comparison of the old and new maps, and changes in individual cities. This year, we're going to start our "2012 White Christmas" forecast maps later this week -- meanwhile we have an article about this graphic and why some areas are more prone to a white Christmas than others.
