Many will see some sleet at the start of tonight's precipitation, but a quick turnover to rain most everywhere as warmer air will be in place above teh surface and make this a cold rain. Immediate deeper valleys of the Piedmont north of Charlottesville and in Western Maryland could see some sleet and even some freezing rain. The warmth will squash my first thoughts of snow west of teh mountains as well, though wrap around snow is possible for the western facing Mountains Monday into Tuesday.
Colder air will settle into the region for a few days and then some warming Thursday to the 50s and even a few 60s! We will have colder air again by next weekend as temps remain in the 40s and low 50s at most for highs. The colder air could lead to another wintry threat later next weekend.
So we have a very cold rain for most areas with some colder pockets causing sleet. Then a cold and breezy aftermath Monday into Tuesday. A slight warming Wednesday into Thursday with some colder air again by next weekend.
