* Wind Advisory for D.C. metro area 7 p.m. tonight thru 7 a.m. Sunday *
11:25 p.m. update: Widespread wind-whipped light snow has settled into the D.C. area now - with a few moderate patches. With temperatures well below freezing, this snow will easily dust roads so use caution traveling. Snow accumulation will generally range from a dusting to half inch (with some locally higher amounts to 1”). The snow will be hard to measure being blown around by the wind, gusting over 40 mph at times. It should be tapering off by around 1 a.m.
And it’s cold out there! Wind chills range from the high single digits to mid-teens.
9:30 p.m. update: Scattered snow showers and flurries are sinking south from Pennsylvania and northern Maryland into the region. They’ll be hit or miss and probably just produce a dusting or so where steadier activity occurs as they come through over the next several hours. But with temperatures falling through the 20s, a slick spot or two is possible.
From 4:15 p.m.That brief burst of snow that left a dusting on grass in parts of the metro area this afternoon was triggered by an arctic front - the strongest we’ve seen this winter so far - now heading east of D.C. While a few snow showers remain possible through evening, the bigger story now becomes falling temperatures and increasingly gusty winds. Old Man Winter has been M.I.A. for much of the season, but he’ll make his presence known tonight and tomorrow.
Here’s a brief summary of what to expect...
Snow: A few snow showers are possible through evening into the early overnight, with models hinting the best chance around 8 p.m.-midnight. They would probably be hit or miss and may end up being rather sparse, but where they do occur, a coating is possible as well as quickly deteriorating road conditions.
Temperatures: Readings that were near 40 earlier this afternoon were knocked down to the low-to-mid 30s as the front came through, and sink to the 20s this evening. That’s cold, but the bigger story is the wind...
Wind: Expect winds to increase to 25-35 mph as we head into evening, with occasional gusts near 40-50 mph. That means wind chills down into the low 20s and teens this evening and overnight, maybe some single digits in the coldest spots.
