Excitement across Wyoming and our nation continues to grow as
Christmas quickly approaches. What are your chances for the
desired “White Christmas?” The National Climatic Data Center has created
a probability graphic of having a 1″ snow depth on Christmas using data
between 1981 and 2010 (image on the left).  The National Operational
Hydrologic Remote Sensing Center estimates snow depth across the entire
U.S. every day through many different data sources.  The image on the
right shows the approximate locations where snow is located across
Wyoming.  Click on either image to enlarge them.
