Minnesota. Maine. Upstate New York. The Allegheny Mountains of Pennsylvania and West Virginia. Practically anywhere in Idaho. And of course, the Rockies or the Sierra Nevada Mountains. These are the parts of the Lower 48* where weather history suggests you want to be if you're looking for the best chance of a white Christmas.
The map at right shows the historic probability of there being at least 1 inch of snow on the ground in the Lower 48 states on December 25 based on the latest (1981-2010) U.S. Climate Normals from NOAA's National Centers for Environmental Information (NCEI). The background map shows interpolated values for all locations. (Interpolating means estimating unknown values using known values and physical relationships, such as the way temperature is known to change with altitude.) You can also click and zoom in to specific stations used for the interpolation.
Darkest gray shows places where the probability is less than 10%. (Sorry West Coast, Gulf Coast, Deep South!) White shows probabilities greater than 90 percent.
