The Weather Channel's app predicts a 40 percent chance of "rain/snow showers" on Monday - Christmas Day - in the Jackson area, with a high of 43 and a low of 26.
Other major guidance models, including the normally reliable European model, are projecting a later return of colder air. It pushes high temperatures into the upper 40s/lower 50s by Saturday the 23rd.
Early models indicate we could see 2 to 5 inches of snow on Thursday, and another 4 to 8 inches on Saturday. This could lead to the coldest weather so far this season Christmas Eve and Day.
Light snow is possible Tuesday morning.
EPS computer model snow forecast for Christmas. Of course, winter came early this year with three rounds of accumulating snow in the past ten days and plenty of cold to accompany it. Below is what the model shows for temperatures in the afternoon on Christmas eve.
Thursday: High pressure will make for a dry but chilly day up and down the Eastern Seaboard.
Consequently the snow line will rise to over 1,000m, with heavy rain forecast below that level in many places on Friday night. Rain should end as snow in the higher elevations from West Virginia to Maine.
Unsettled weather is forecast for the weekend, with some national media outlets reporting on the possibility of Storm Dylan.
Snow may break out in parts of the Tennessee Valley and Ohio Valley, but the details are vague for now. Both models eventually show very cold air coming to most of the US over the next week to ten days.
Although the name has been selected, the Met Office will not yet put "Storm Dylan" into use until "medium weather impact" from rain, wind or snow is forecast. For Virginia, that means highs in the 30s and lows in the teens.
AccuWeather forecasts disruptive travel for the holiday period December 21-26 from the Rockies to the northeast.
Baltimore has an outside chance of having a white Christmas, but any snow will require a quicker-than-expected intrusion of cold air.
