Another big, winter storm has been whacking the central and southern plains and now it is on the move. As the storm center heads east into the TN Valley, it appears likely that a new area of low pressure will develop along the NC coast. This 2-storm complex will bring rain and warmer air to our area. For areas east of the Blue Ridge it will be a rain storm…although it may briefly begin as a wintry mix….but rain it will be and perhaps enough to cause flooding. Rainfall could total 1”-2”.

Meanwhile, west of the Blue Ridge and at elevations above 1.000 feet, an icy mess may be created tomorrow with a prolonged period of sleet and freezing rain. By Wednesday, this dynamic storm complex will create a breezy and very warm day. We are forecasting partly sunny skies with highs in the upper 50s. But on Thursday and Friday, colder air will return to our area. And over the weekend, unseasonably cold air will overspread the entire mid-Atlantic region…Washington, Baltimore and your backyard included.
