5:20 p.m. update: Dry air has fought off the storm and decimated snow chances for D.C. Radar shows precipitation trying to reach D.C. getting pushed away to the east and southeast. Some spotty precip may still try to sneak back in, but the chance for accumulating snow is over in my estimation in the immediate D.C. area. For our latest forecast, see our PM Update just published.
4:00 p.m. update: The precipitation in central Virginia is now sneaking into D.C.’s south and southwest suburbs. We have reports of a little rain and sleet around Alexandria, and even some light snowflakes in Centreville and Chantilly. Farther south, into Charlottesville, rain has switched to all snow (webcam of Downtown Mall). A mix of rain/sleet/snow should continue creeping towards D.C. proper, but with temperatures well above freezing and precipitation intensity light, accumulation is not expected for the next 1 to 2 hours.
3:00 p.m. update: Precipitation still hanging back in central and southern Virginia - rain is starting to transition to snow in Charlottesville and sleet is mixing with rain in Richmond’s western suburbs. Check out this image: Wintergreen ski resort . And to make local snow lovers even more jealous, look at the snow way to the south: Tuscaloosa, Alabama (Bryant Denny Stadium)
2 p.m. update: Steady precipitation - a mix of rain, sleet and snow - is moving into central Virginia and southern Maryland. However, it’s hitting a wall of sorts and may only creep northward towards the metro region over the course of the afternoon. Around Charlottesville, rain is falling but traffic cameras show the precipitation changing to snow to the south and west. In southwest Virginia, Wise already has an impressive blanket of white and the National Weather Service is calling for snow at a rate of 1-2 inches an hour in the region.
Overview: The National Weather Service has discontinued its winter weather advisory for most of the Washington, D.C. metro area. D.C.’s far southern suburbs (including southern Fauquier, Stafford, Calvert and Charles counties) are under advisories, but the winter storm warnings previously in effect there were cancelled.
Despite the dropped advisories/warnings, there’s some possibility of snow in the metro area, mainly this evening. Precipitation is likely to start as rain and sleet, as temperatures are still in the low 40s. We might still see some very modest snow accumulations, mainly from the District and points south (of Rt. 50).
Any accumulation would be favored on grassy areas, but some slick spots could develop around and after rush hour in places where steady snow falls. Such slicks spots are most likely the farther south and southwest of D.C. you go. Please refer to our earlier blog post for our accumulation map and regional specifics. We favor the lower end of our accumulation range provided in said map - generally less than 1 inch in the immediate D.C. area and perhaps as little as a trace.
