D.C.-area forecast: Wintry mix this morning with icy spots possible, plain rain by afternoon (UPDATES)


* Winter weather advisory through 1 p.m. north and west of the District | School delays/cancellations *

11:15 a.m. update: Except for our easternmost counties, where precipitation will begin soon, freezing rain and rain has now overspread the entire metro region. Temperatures are generally at or above freezing from the District and to the south and east where the National Weather Service decided to discontinue the winter weather advisory.

Outside the Beltway to the north, west and southwest, temperatures are generally 32 or 33 degrees within a one county radius of the District. In these areas, it is just warm enough that ice is melting on most surfaces, but may accumulate some on tree limbs and elevated surfaces.

In Loudoun, northern Fauquier, northern Montgomery, Frederick, western Howard, and Carroll Counties, we are seeing reports of icy sidewalks and some other untreated surfaces as well as ice buildup on trees and other elevated surfaces.

Throughout the region, temperatures should gradually rise above freezing by 1 p.m.

What this winter lacks in snow, it’s making up for with cold and brief bouts of mixed precipitation. That’s exactly what we have this morning, with icy spots possible and many school delays as well as the federal government. By afternoon it’s just plain rain, before gusty winds try to dry us out tonight. We’re chilly again tomorrow before a warming trend Friday into the weekend, with rain likely late Saturday into Sunday.

Today (Wednesday): A patchy mix of light freezing rain and sleet moves through early this morning, except a bit steadier for a time in parts of Loudoun, Frederick, and Carroll counties. With early-to-mid morning temperatures near or a bit below freezing, icy spots are possible, mainly on sidewalks and driveways, ramps and bridges, and some untreated roads. From D.C. toward points south and east, temperatures should rise just enough above freezing by around 9 a.m. to melt any ice. But icing may remain a threat in our northern and western suburbs as late as around 11 a.m. Plain rain continues through the afternoon, moderate at times, with a wide range of afternoon highs — from the upper 30s north and west, to the low 50s south and east. Expect 40s to about 50 near and inside the Beltway. Confidence: Medium

Tonight: The rain should exit from west to east this evening, from about 6-8 p.m. We’ll see winds pick up through the evening and overnight, with gusts near 35 mph from the northwest, as skies clear partially. The winds should help to dry things out, but we still may see a few of those remaining wet spots freeze up again as temperatures drop toward overnight lows in the mid-20s to near 30. Confidence: Medium-High

Tomorrow (Thursday): Still on the breezy side, with morning winds from the northwest around 10-20 mph, before diminishing in the afternoon. Otherwise, we’ve got plenty of sun as high pressure takes control. But we’re also plenty cold, with highs in the mid- to upper 30s. Confidence: High

Tomorrow night: Skies turn partly cloudy as high pressure starts to shift to our east. Conditions are seasonably cold, with lows in the 20s to near 30, with light winds. Confidence: High


Friday and Saturday are partly to mostly cloudy and somewhat milder days, with Friday highs in the mid- to upper 40s and Saturday highs near 50. Our next system, coming up from the south, brings a chance of rain showers Saturday afternoon, with rain likely Saturday night into Sunday. Highs on Sunday should climb into the 50s. Friday night lows dip to the 30s, with Saturday night lows holding up in the 40s. Confidence: Medium

Expired updates

10:00 a.m. update: Freezing rain is edging closer to our immediate western suburbs, about to enter western Fairfax and Montgomery counties. Freezing rain or plain rain (from the District to the south and east) will overspread the entire region over the next hour or two.

Temperatures throughout the region range from 30 to 35 degrees, warmest in downtown Washington and to the south and east and generally freezing or below north and west of the Beltway.

Because temperatures are hovering at or close to freezing as this precipitation is moving in, the National Weather Service has extended the winter weather advisory until 1 p.m. even inside the Beltway. Close to and in the city “most paved surfaces will be wet and ice accretion will be mainly confined to elevated surfaces,” the advisory says. “Be prepared for reduced visibility at times.”

In our colder areas well north and west of the Beltway (northern Montgomery, Loudoun, Frederick, northern Fauquier, Carroll, Howard, and Frederick counties), where temperatures are closer to 30 and 31 degrees, the ice may cause some slippery conditions, especially on untreated sidewalks, neighborhood roads, driveways, parking lots, bridges, ramps, and overpasses. Pedestrians and motorists should use caution.

9 a.m. update: Temperatures remain near or below 32 with freezing rain streaming back into western/northern Loudoun County and Frederick County. Significant icing happening up there, but quiet in and around immediate metro area.

8 a.m. update: A lull in the precipitation should fill in with steadier rain, moving in from west to east, after 9:30 or 10 a.m. By then most spots should be rising just above freezing. But still an icing risk for areas north and west of the Beltway, which may hover right near the freezing mark until 11 a.m. or so.

6:30 a.m. update: The freezing rain, perhaps with a bit of sleet mixed in, is mainly focused north of D.C., I-66 and Route 50. No major icing issues south of that line and not expecting any. Icing, especially on untreated and elevated surfaces, continues more of a risk across our northern tier including northern Loudoun, northern Montgomery, Frederick, and Carroll counties until 11 a.m. or so. By then temperatures should be climbing just above freezing. Some school systems north and west of DC that had a 2-hour delay are now closed. Make sure to check the latest information on delays and closings.

5:30 a.m. update: We have patchy areas of light freezing rain and perhaps sleet moving through. So far it’s been spotty and we’ve only heard reports of a bit of ice on cars and fences. Pavement in good shape. Precipitation may increase a bit through around 7 a.m., so be continue to be careful, especially on sidewalks, driveways, ramps and bridges. But we don’t expect widespread icing on roads, except perhaps in parts of Loudoun, Frederick, and Carroll counties where precipitation is a bit steadier the next hour or so. Temperatures, currently around 30-32, should be mostly above freezing by around 9 a.m., except perhaps not until around 11 a.m. for our further out northern and western suburbs.
