Another wintry mix possible this Saturday in the D.C. area

Another disturbance, another chance for a light wintry mix in the area this weekend.

As cold air continues to hang around the Continental U.S., any system that  develops has had the potential to bring snow.

This weekend will be no different, as enough cold air will be in place for the potential of another wintery mix in the D.C. area. Once again, the hot spots are anticipated to be in the common locations north and west of D.C.

Low pressure is expected to move into the region from the southwest. High pressure over Canada will help ensure a supply of cold air at the surface, but it shouldn't be as strong of a cold air damming situation that brought the icing to the region last weekend.

At this time, it appears light snow may develop in the late morning hours Saturday, changing to rain by the afternoon in the D.C. Metro and points southeast. As surface temperatures in those locations are expected to be above freezing, it should turn out a lot like Tuesday, with little to no snow expected.

Farther north and west, however, temperatures may hang at or below freezing for much of the day, resulting in light accumulations on par with the snow that accumulated in those areas Tuesday.

Everyone in the D.C. Metro saw what can happen when temperatures are only a degree or two above freezing, as snow is again may melt on contact with little disruptions to the city.

Northwest into western Fauquier, Loudoun, northern Montgomery and points west, light snow may again be possible. Pinpointing accumulations at this point isn't very smart as accuracy would be exceptionally low, but the possibility for a few inches of snow is possible through Saturday evening. We'll be sure to keep you updated when we learn more!
