Discussion              

An active weather pattern continues into the new year likely bringing the Mid-Atlantic region an accumulating threat this weekend and there are a couple other systems to monitor as well. One system will drop southeastward from Canada on Thursday and interact with a low pressure system near the southeastern US coastline and the combination can produce some rain and/or snow shower activity in the area from late tomorrow night into early Thursday. This first system will not be a big deal for us; however, it will intensify significantly when it moves well off the NE US coastline and it’ll end up playing a key role in the potential weekend accumulating snow event. Low pressure pulls out of the southern US this weekend and will push in this direction and it’ll run into a cold air mass over the Mid-Atlantic region thanks in part by the passage and intensification of the first system. The ultimate storm track for the weekend is still in some flux, but the potential is there for accumulating snow in the Mid-Atlantic region and, in some areas, the most in a long time.
