Low pressure will take shape overnight off the coast of South Carolina and move toward the northeast Wednesday. At this point, this system will bring mostly, if not all, rain to areas along and east of I-95. Because this storm will have to generate its own cold air, areas of measurable snow will likely be at higher elevations north and west of the District, especially along the ridge lines where totals may exceed six inches. Rain will overspread the metro area during the overnight hours and come to an end as snow by late afternoon or early evening. Snow totals inside the Beltway will be limited to a trace to one-inch.
An upper level system may bring periods of rain or snow to parts of the area Thanksgiving Day.
