* Winter weather advisory for the most of the area tonight (map) | Wind advisory 2 a.m. to noon Friday entire region | Wind chill advisory Frederick, Carroll, northern Baltimore, Montgomery and Loudoun counties 4 a.m. to noon Friday * | Winter storm snarling travel, delays expected to continue Friday | Latest snow amounts | School Closings
11:45 p.m. update: Steady snow has exited the District for the most part and is rapidly tapering off in our western suburbs. By 12:30 a.m., the balance of this snow event will gradually be over – although some light snow showers and flurries could still pass through the area through 3 or 4 a.m. (especially north and northeast of the District).
For the rest of the night, the big story will become the falling temperatures and increasing winds. Temps fall into the mid-teens to near 20 by around dawn. Everything that is wet and slushy will freeze overnight so be extremely cautious walking/driving in the morning.

Towards morning, winds from the northwest strengthen to around 20-25 mph, with gusts as high as 40 mph. With snow on the trees, there could be some isolated power outages.
The daylight hours Friday are frigid, with steady temperatures holding in the high teens and low 20s and winds gusting to 30-50 mph at times. Wind chills will be in the single digits!
This is the last update tonight. Thank you for following our coverage today. We’ll have more tomorrow starting at 5 a.m.!
11:20 p.m. update: The back edge of the snow has moved inside the Beltway. It’s about over for the District and will end in areas in Maryland east of I-95 in the next hour to 90 minutes.

10:57 p.m. update: The winter storm warning has been dropped for Frederick and Loudoun counties, where snow has ended.

10:45 p.m. update: The back edge of the snow is pushing east again, and snow is tapering off in western Fairfax and western Montgomery County. It now looks like we’ll see an end to steady snow inside the Beltway between 11 and 11:30 p.m. and in the eastern suburbs between 11:30 and 12:30 am. We can’t rule out a bit of light snow developing on the back edge which keeps the snow going a little longer than these projected times. But, already, much of the area has seen the majority of its accumulation.
10:35 p.m. update: Below is a map of snowfall total reports received by the National Weather Service between mainly 7 and 9 p.m.
Amounts are generally 1-3″, with some isolated 4 and 5″ totals in far west and northwest areas. Of course, it doesn’t include the last 1-2 hours of snow, in which 1″ or so has fallen including in areas which hadn’t received much earlier this evening around D.C. and to the east.
10:20 p.m. update: Although the snow is over in our far western suburbs – which got some of the heaviest totals from the first phase of the storm – it continues to fall at a pretty good clip in the immediate metro area and eastern suburbs. The back edge is trying to push east, but is meeting some resistance and another hour or two (eastern suburbs) of steady snow is possible.
Some advice: consider shoveling and salting sidewalks tonight. By tomorrow morning, everything will have frozen solid and the task will be much more difficult.

9:45 p.m. update: The back edge of the snow continues advancing eastward. This storm may have come in a little earlier than expected and may also depart a bit earlier. The snow is mostly over in Loudoun and Frederick counties (although – per below -some lighter snow showers and flurries are possible overnight). But in the immediate D.C. area and eastern suburbs, it continues to snow steadily. It’s a scenic snow and a great night to stay in and just watch it…especially with the slushy and slick roads out there.

9:15 p.m. update: Radar is showing the snow starting to shut down in western Loudoun and Frederick counties. Around Leesburg and Frederick, you’ve probably seen the bulk of your snow – although some intermittent snow showers may still come through. Closer to town and especially to the northeast, we should see steady snow continue until 11 or midnight, before activity becomes intermittent and light.

8:45 p.m. update: While all of the area is seeing snow, and much of it good snow, it appears the sub-2 inch snowstorm streak, closing in on three years now, is putting up quite a fight as far as official D.C. records go (as reported from from Reagan National Airport). Check out this shot from Crystal City right near the airport, where temperatures have remained near or above freezing:

Just five miles away, and a few hundred feet higher, it’s a winter wonderland in northwest D.C. where temperatures have been near or just below freezing.

8:20 p.m. update: Loudoun and Frederick counties have been upgraded to Winter Storm Warnings. The National Weather Service expects 3-6″ of snow in this area, and many spots are in or near that range already per reports.
8:10 p.m. update: The freezing line is slowly shifting south and east, causing additional roadways to deteriorate. The heaviest band, which pushed through the I-95 area earlier this evening, has shifted east. But light to moderate snow continues across the area, and as the airmass continues to cool snow is becoming fluffier. Short-term models and radar trends indicate that we should see persistent accumulating snow across the region for at least the next few hours before it becomes more showery heading into the overnight. Once you get near and west of the Blue Ridge, snow may come to an end quicker (next hour or two) as the back edge is fairly close now.
7:45 p.m. update: The National Weather Service has expanded the winter weather advisory to include the rest of the local area. D.C., Fairfax, and Prince Georges counties are the new additions. They are now expecting 1-3″ across this area, in line with our snow forecast.
7:20 p.m. update: Snow is falling steadily throughout the region with reports of snow-covered roads into the District. Radar is starting to show the western edge creep eastward, but – even if its intensity wanes a bit – snow is likely to continue for several more hours, especially east and northeast of the District.

Overview: Snow will fall in the metro area, ending between 1 a.m. and 4 a.m. from southwest to northeast. Generally, we expect 1-3 inches of snow, although locally higher amounts are possible, especially in the colder north, northeast and northwest suburbs. 2-4 inches or more are possible around Baltimore. Temperatures will gradually fall from 30-34 (northwest to southeast and around the city) through the 20s overnight, meaning wet roads and sidewalks will freeze up.
Towards morning, winds will rapidly increase with winds gusting over 30 mph and possibly as high as 40-50 mph. In Montgomery and Loudoun counties and to the north and west, the combination of temperatures falling into the teens along with the wind has prompted a wind chill advisory. Wind chills will drop to between 0 and 5 below zero early Friday morning. They’ll be in the single digits elsewhere.
Between the snow and the incoming wind and cold, we expect some school delays and perhaps closings Friday. Precipitation may end early enough for main roads to be treated, but side roads may be icy with temperatures dipping through the 20s after snow ends.
Alexandria, Arlington, Prince George’s, Charles, Stafford, and Prince William counties:
1.5 apples: 50/50 chance of a delay. 25 percent chance of closing.
Montgomery, Howard, and Anne Arundel counties:
2 apples: 50/50 chance of closing. Good chance (better than 50/50 chance) of a delay.
Note: Loudoun and Fauquier County schools have already decided to close.
Two domes: 50/50 chance of unscheduled leave policy and/or delayed opening
9:53 p.m. update: The OPM Web site says the Federal government will be open with an unscheduled leave policy in effect Friday.
