For those who want a white Christmas, that will be a challenging thing to get this year, but not impossible if you define a “white Christmas” as flakes. A powerful cold front will move through our region on Christmas Eve, and temperatures behind it will crash quickly. We will go from the 60s all the way down into the 20s perhaps by the morning of the 26th. Christmas morning looks to be a cold one, with lows in the low 30s at least. This will be our coldest Christmas in years, as the previous few have been warm. Last Christmas it was sunny and warm here in the Carolinas, with no signs of snowmen anywhere.
The Euro model below has a decent shot of cold for the Southeast for the Christmas morning. Below are the temperature departures from average. But how cold are we expecting?
As it currently stands, we can expect the coldest temperatures from this Arctic outbreak on Saturday morning the 26th. While Christmas morning will be cold with lows in the low 20s in NC and 30s in SC, the real frigid temperatures will come on the morning of the 26th. This is going to be the coldest air of the season for sure. Widespread lows in the 10s across NC and 0s in the mountains (teens and single digits) and 20s across SC are expected.
Since this is a cold frontal passage, it’s hard to get snow with these. It will possibly be a severe weather event and/or flooding ahead of the cold front on Christmas Eve, and then cold and windy behind it. There could be some flakes in the mountains but we are not expecting a snow event across the Carolinas at this time.
But at least it won’t be 70 degrees on Christmas, unless you are in Florida.
