Forecasting the Impact of El Niño on Christmas Snowfall

The chances of a white Christmas in the contiguous United States are shrinking due to human-caused climate change and abnormally warm temperatures expected this year. However, there are still some regions where a white Christmas is more likely, including the western U.S. mountains, parts of the northern and central Plains, and the Northeast U.S. mountains. Cities such as Denver, Lake Tahoe, and Spokane have a higher chance of having at least one inch of snow on the ground on Christmas Day. Overall, snow cover across the Lower 48 is currently below average, with temperatures forecasted to be well above normal in many areas.
