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.
