The toughest part of the forecast for Saturday is whether we’ll see any extended sunshine. There is a strong temperature inversion in the atmosphere in the lowest few thousand feet of the ground. Most of the time, the temperature decreases with height, but in the case of an inversion, it increases. In the winter months, with the low sun angle, these temperature inversions can last for days and trap moisture, in the form of clouds, close to the ground. Above the inversion, there may not be a cloud in the sky. But below it, where we live, the clouds will shield us from the sun. As such, I am calling for some limited sunshine, but overall, I think the clouds may hang on. There is a slight chance of a few flurries or even a period of freezing drizzle and highs should be around 32. Sunday looks partly sunny to mainly cloudy with highs around 34. Winter also arrives Sunday at 6:03pm local time.
I’m keeping an eye on a fast moving area of low pressure for late Monday into early Tuesday morning. I’m going to keep Monday dry, but into early Tuesday morning there could be some rain and snow. Highs Tuesday will be in the upper 30s to near 40.
Our long range models all agree on a very large, and strong, storm developing and affecting us on Christmas Eve. I still think the bulk of the precipitation with this storm on Wednesday will be rain. However, depending on how fast the cold air can get drawn in to the region, we may see some snow showers toward Christmas morning. Highs on Wednesday should be in the upper 40s (possibly higher) with lows in the 30s. Christmas day looks colder and windy with a chance of snow showers.
The Christmas Eve and Christmas Day time frame could pose some travel issues on the ground and at the airports throughout the northeast and Great Lakes region. Please monitor the forecast. Also, it’s a good thing Santa doesn’t use airports or the ground to travel around the world. He has never missed a Christmas delivery and I don’t expect him to this year, either!
