While some may be dreaming for a white Christmas, many are wondering if their dreams will turn into forecast reality. The map here 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) US Climate Normals from NOAA’s National Centers for Environmental Information (NCEI).

The 1981–2010 Climate Normals are the latest three-decade averages of several climatological measurements. This collection contains daily and monthly normals of temperature, precipitation, snowfall, heating and cooling degree days, frost/freeze dates, and growing-degree days calculated from observations at approximately 9,800 stations operated by NOAA’s National Weather Service (NWS).


While the map shows the historical probability that a snow depth of at least one inch will be observed on December 25, the actual conditions in any year likely vary from the norm. Different weather patterns and storm systems each December set the stage for whether or not there will be snow on the ground for Christmas Day.

The December 2019 weather pattern has been an active one with early season significant snowfalls in both the west and the east. Even Hawaii has seen heavy snow in recent weeks. In such an active weather pattern, it’s difficult to know this far out who will have snow on the ground for or on Christmas Day itself; that will be better known in about 5-6 days from now.

To see if we’re calling for snow for your area, visit our local weather forecast page for your specific town; Christmas forecasts for each local area will be updated in a week from now.
