Christmas is only a few days, and the forecast uncertainties on whether you will have a white Christmas this year are increasing. Below, you’ll find our potentially find our last white Christmas map, unless the forecast changes anymore.Snow is likely across the Intermountain West through much of the Northern Plains. Great Lakes and interior Northeast. There is snow cover currently on the ground and the upcoming intrusion of cold air will allow for most–if not all–of the snow to remain on the ground through at least Christmas Day.
Now there are three areas in the U.S. where a white Christmas is possible. Another round of snow may move into southeastern Washington this weekend, but it won’t add up to much. In the Midwest from Omaha through Chicago, there is the slight chance for snow cover with a narrow swath to the south of where we think it is possible. Then in the Northeast, the chances are actually increasing along the coast from Philadelphia through Boston. There will be a coastal storm that develops, but it depends on the exact track of this low. The track will determine the placement of the rain/snow line, which is still to be determined.
To the south of the ‘Likely’ and ‘Possible’ chances is where a white Christmas is unfortunately unlikely.
