Christmas Storm Potential Update

There has been no substantial change in the outlook for some snow on Christmas. Details on a possible storm track and snow amount are very much up in the air at this early stage but most computer models agree that some snowfall on Christmas is likely.

The Tuesday afternoon satellite picture shows a new storm coming on to the Pacific coast and this will likely be the one that will start the ball rolling on the next storm to move toward the East Coast.

The current thought is that the storm will move in Christmas Day with snow possibly continuing into Sunday. This is a little slower than earlier forecasts. It appears that temperatures would be cold enough for all snow.

The forecast map above is for Sunday morning with the storm off Cape Hatteras and beginning to turn up the coast. The map below is for Monday morning showing the storm center approaching Cape Cod as a nor’easter.

The key for the Mid Atlantic Region is how close the storm will be to the coast line and that is a question that can not be answered at this early stage. The storm’s proximity to the coast will influence the amount of snow the area receives. Two model runs in the past 24 hours have pegged a snow total range anywhere from a trace to as much as ten inches with the latest forecasting on the low side with up to four inches. As you can see, much fine tuning is needed before a definitive forecast can be issued.
