9:30 p.m. — Overnight snow chances have increased

There’s a pretty strong consensus among computer models that we will see a period of steady precipitation between about 1 and 7 a.m. Wednesday. It may begin as rain but temperatures should be cold enough for it to quickly change over to wet snow.

Snow may fall at a decent clip between about 3 and 6 a.m.

Temperatures will only be marginally cold enough for much to stick — between about 32 and 35 degrees. So we think most accumulation will be on grassy surfaces, trees and car tops — probably a dusting to a coating with an outside chance of someone seeing an inch. Around downtown Washington and the Potomac River (including Reagan National Airport), most of the snow probably melts. In our colder areas north and west of the Beltway, we can’t rule out a few slick spots early Wednesday as temperatures fall to near freezing.

Early risers may get a chance to spot some of the snow as models now suggest the snow could linger until between about 6 and 8 a.m.

Be sure to check conditions before heading out in the morning.

From 5 p.m.

Intermittent light rain plagued much of the day. Add in temperatures dipping to around 40 this afternoon and it felt a lot more like January than it has most of the month. As temperatures continue to cool off into tonight, lingering rain will change to snow. We’re not likely to see a whole lot of snowfall, but in a season such as this, even the potential of a dusting is big news.

Through Tonight: After a lull in precipitation this evening, a period of rain and snow showers turning to light snow could break out overnight. Relatively mild temperatures near and above freezing during much of the snowfall probably will limit accumulation to a dusting or so on grassy or elevated surfaces. There may be a few slick spots north and west by the morning, with lows in a near-30-to-mid-30s range.

Tomorrow (Wednesday): Keep an eye out for a couple of slick spots early. Otherwise, we should see clearing skies with time as winds kick up from the north. Highs will be pretty close to 40. Winds will gust upward of 25 mph in the afternoon.

Snow!? Washington has made it to its fifth-latest point in the season with no snow accumulation. It’s the least snow at this point since 1973. There’s a chance we will break the snowless streak tonight. The Weather Service is forecasting 0.2 inches for Washington, although that could be difficult. As we know, measuring much of anything can be tricky at the airport, so we’ll see …
