Based on the most recent model data, we have updated our white Christmas forecast map based on the minor changes.The greatest chance for a white Christmas this year, which is when there is at least one inch of snow on the ground, is across the Intermountain West into the Northern Plains, Upper Midwest, and interior Northeast. There is currently a substantial snowpack for most of these areas, and it will likely stick around as a massive high pressure from the Arctic brings extreme cold to the Central U.S. and below average temperatures to the large majority of the country.

Areas included in the ‘Possible’ risk for a white Christmas is in the Central Plains, portions of the Ohio Valley, and portions of the Northeast. There is a storm that will bring a light snow to much of the Central Plains Thursday into Friday, so it is possible all of this snow stays on the ground.

Now in the ‘Slight’ risk zone, which includes New Mexico, portions of the Southern Plains, Ohio-Valley, Mid-Atlantic, and Southern New England, the forecast gets interesting, especially in the Northeast. It seemed like the Northeast will have a wet and rainy Christmas, but recently as of Tuesday, the forecast is trending colder and now snow is being introduced for some of these locations. It’s still early to know if this trend will continue, so that’s why we think there is a chance for a white Christmas in these areas.
