It doesn’t really feel like Christmas without snow, so this map is an important tool to utilize during this time of year. If you live somewhere with under a 50% chance of having a White Christmas, you might want to start looking at flights to head north for the holidays. Anyone living in the West, New England, or the Midwest has a relatively good chance of experiencing a White Christmas.
The National Climatic Data Center (NCDC) defines a White Christmas as a snow depth of at least 1 inch observed on December 25. Thankfully, this doesn’t mean that it must snow on Christmas. It just means that there must be at least 1 inch of snow on the ground by the time the clock strikes midnight on December 26th.
