Coastal and Marine Impacts from Imelda and Humberto as Both Track Away from the Southeast U.S.

Historical Chances for a White Christmas?

"Will we have a white Christmas?" It is one of the big questions asked every holiday season. The graphics and table below were created from historical data from NOAA'S National Climatic Data Center (NCDC). It reflects the normal chance, or probability, of a white Christmas based on data from the 1981-2010 three-decade averages. A white Christmas is defined as having 1 inch or more of snow on the ground Christmas morning. The graphics provide a general sense of the likelihood of a white Christmas over the entire country and the Midwest. They are based on the latest (1981-2010) U.S. Climate Normals from NOAA's National Climatic Data Center. For a specific location in Eastern Iowa, Northwest Illinois, or extreme Northeast Missouri, refer to the table. The table is also based only on data from 1981-2010. For more information, Click HERE.
