The Old Farmer's Almanac forecasts NYC will not receive the one inch of snow required for an official White Christmas, with above-average temperatures and below-normal snowfall predicted for the region. Historical data shows measurable snow on Christmas Day in NYC occurs roughly 12% of the time, though NOAA's climatological average is 13% for at least one inch on the ground. El Niño conditions favor above-normal temperatures across the Northeast through the season.
