Things certainly are changing in the atmosphere from a warm and dry pattern to more of a cold and wet pattern in the southeastern U.S.
As I’ve been talking about for a while, the pattern seems to be flipping back to a more winter-like one for the end of this month. While I certainly can’t tell for sure if we will see snow anytime soon, the pattern is looking favorable for many chances. The first being next week followed by a couple more storm before Christmas.
Next week's storm:
The good news in all of this is we might finally be getting some much-needed rainfall. While there is a slight chance of snow next week it looks mainly confined to the mountains.The storm track also becomes much more active as the cold air settles south.
The southern storm track from the Gulf of Mexico into the northeast become our dominate track from now until the first of the year. So expect many more storms over the next two to three weeks.
What about the cold air?
Pretty much all of the short-range climate models shows this “flip” back to cold. These images are 10 chuck of temperature anomalies from the model output. So what you are looking at is the departure from normal temperatures. The color key is on the right.
What about snow?
Well, as always, this is a lot harder but just for fun here is the CFS climate models snow depth forecast. Remember these four panels are four runs or ensembles of the model for the 10-day period from Dec. 21-Dec. 31, which does include Christmas.
So what the model is trying to show is the maximum snow that might occur at some point in this time frame. Just for fun so...not a forecast.
