Service Description: These data show 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 (1991-2020) U.S. Climate Normals from NOAA's National Centers for Environmental Information. While the data provide fields records of the climatological probability that a snow depth of at least one inch will be observed on December 25, the actual conditions this year may vary widely from these probabilities because the weather patterns present will determine the snow on the ground or snowfall on Christmas day. 

For a more detailed assessment of the probability of a white Christmas, as well as documentation of the methodology used to calculate the underlying climatological statistics of the original version of these data (using 1981-2010 normals data), see the scientific paper, White Christmas? An Application of NOAA’s 1981-2010 Daily Normals, by NCEI scientists and published in the Bulletin of the American Meteorological Society.
