What is the Historical Probability of a White Christmas in Your State?

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.

For those of you dreaming of a white Christmas, you can find places that have the best chance of being a winter wonderland according to weather history. The “Historical Probability of a White Christmas” map shows the climatological probability of at least 1 inch of snow being on the ground on December 25 in the contiguous United States. On the map, dark gray shows places where the probability is less than 10 percent, while white shows probabilities greater than 90 percent. 

If you would like to keep track of the snowfall across the United States on a daily basis, see the National Operational Hydrologic Remote Sensing Center’s National Snow Analyses.
