Where does history say you should be in the United States for the best chance of seeing a white Christmas?
Based on NOAA's 1981-2010 Climate Normals, the highest probabilities along the East Coast will take you Upstate New York, Vermont, New Hampshire, and Maine.
Throughout the Western US, you should take aim for the spine of the Rocky Mountains in western Montana, Idaho, Wyoming, and Colorado. Further West, you'll be looking at the Sierra Nevada mountains of California and the Cascade Range of Washington and Oregon.
While the map shows the climatological probability of snow-covered ground, the actual conditions will vary due to changing weather patterns on and/or around Christmas Day.
