11:30 a.m. update: The very last of the left-over light snow is passing through our western suburbs and should pass through the entire region by 1 p.m. Then, aside from a few flurries, it’s over. The sky may brighten this afternoon, but I don’t see a lot of sunshine or serious melting, as temperatures max out from around 29-33.

8:10 a.m. update: A small area of light snow/flurries is moving back into the region from the west. This is more of the conversational variety, and shouldn’t add much accumulation.

7:05 a.m. update: The last band of snow has dissipated and is exiting the region to the northeast. We could see some snow showers and flurries behind it this morning (40 percent chance), but – after 5-10 inches of snow – much of the accumulation is finished.

 

6:35 a.m. update: This last band is weakening and fairly rapidly streaking off to the northeast. It’s already clearing Manassas and should clear the District just after 7 a.m. and our northeast suburbs by around 7:30 a.m.

 

6:05 a.m. update: Yes, the final heavy band is pushing through the metro area. It’s currently covering Prince William and Fairfax County, as well as southern Montgomery County and will pass through the District in the next hour or so, and then our suburbs to the east and northeast in northern Prince George’s, southern Howard, and northern Anne Arundel counties before 8 a.m. This last band could drop another 1″ or so. Then just a chance of some intermittent snow shower/flurry activity.

5:40 a.m. update: Frequent question: When does it end? Per the 5:10 a.m. update, the steady, accumulating snow probably winds down between 7-8 a.m. in the immediate metro area. In some of our far western suburbs, it’s already beginning to diminish. But even after 8 a.m., we can’t rule some scattered snow showers/flurries or areas of snow affecting the region through around midday.

5:10 a.m. update: After 5-10 inches of snow in the region overnight, it continues falling at a good clip. However, the back edge of steady snow has moved northeast of Charlottesville and should work its way towards the metro region in the next 2-3 hours. Another 1-2 inches of accumulation or so are still possible.

FORECAST IN DETAIL

After heavy snow overnight, periods of snow continue today, but gradually decrease. Absolutely use caution this morning as many roads are snow-covered and treacherous.

With the area covered in white, it’s easy to forget our normal high is in the mid-50s.  We won’t be close to that through Wednesday, but there are signs we break through Thursday and could even be back near 60 by Friday. A cold front  passing Saturday chills us back down with colder than normal temperatures returning by Sunday.

Today (Monday):  Snow continues intermittently this morning, with another 1-2 inches of accumulation possible.  In the afternoon, snow tapers to flurries.  It’s unseasonably cold, with highs only around 30 or into the low 30s. Winds are from the north at 10 mph gusting to 20 mph at times. Confidence: Medium

Tonight: The storm exits but clouds remain. It’s cold, with lows ranging from the mid-to-upper 20s.  Light winds. Confidence: Medium-High

Tomorrow (Tuesday): A cloudy, raw, and cool day.  A little wave passing by our to east may even throw back enough moisture for a period of light rain and/or snow showers.  Temperatures rise into the upper 30s so there’s little or no concern of accumulation. Winds are light from the east. Confidence: Medium

Tomorrow night: Continued cloudy with a chance of drizzle (and maybe a few pockets of freezing drizzle in our colder suburbs north and west of the District).  Lows range from the low-to-mid 30s. Light winds. Confidence: Low-Medium

A LOOK AHEAD

Wednesday we may well be wedged in with clouds and some morning drizzle.  A round of showers is possible in the afternoon as a cold front pushes through.  It remains chilly, with highs 45-50.  Partial clearing finally Wednesday night with lows in the 30s to near 40 (downtown). Confidence: Medium

Thursday and Friday bring milder temperatures. With an assist from partial sunshine, Thursday reaches the mid-50s with overnight lows in the 30s. Friday may well be the pick of the week, with sunshine and highs climbing to near 60. Partly cloudy Friday night with lows in the 30s. Confidence: Medium

Saturday’s on the mild side, but rain showers may threaten as a cold front punches through the region.  Highs may reach 60 before any showers arrive.  Clearing Saturday night and chilly, with lows in the upper 20s to low 30s (suburbs to city).  A cold air mass settles in for Sunday  with highs probably in the 40s. Confidence: Medium
