FORECAST IN DETAIL


Clouds: Latest mid-Atlantic infrared satellite shows movement of clouds over past two hours. Refresh page to update. See more maps on our Weather Wall.

Small snow threats may be on their way, but no guarantee on whether we see a dusting or a couple more inches. Temperatures may be marginal for much accumulation, yet the snow on the ground could help keep us a little colder than without. Bundle up if out late on Saturday night and Sunday night, especially, and be sure to drive extra carefully with snowy roads still around. Are you happy or sad to see our snow and ice slowly melt?

Today (Friday): Morning sunshine is to be enjoyed, since it may wane as the day wears on. Despite the snow cover, temperatures should still thaw into the 35-42 degree range. Light winds may feel a bit chilly coming from the southwest at 5-10 mph, but it is an improvement. Most of us should be able to get successfully (albeit slowly & carefully) to any evening Valentine plans. Confidence: High

Tonight: It looks doubtful we’ll see the full “snow” moon tonight, as an area of light mixed precipitation, mainly wet snow and rain we think, moves in– courtesy of a clipper system. We have about a 70% chance of precipitation. Rain and snow showers could hold off until after about 8 p.m., with higher chances of snow predominating the mixed precipitation after midnight. When all is done on Saturday, a dusting to a few inches is possible depending on how the storm passes by the area, but snow may struggle to accumulate downtown in any case. Southwest breezes slowly decrease, as do the temperatures, toward the mid-20s well outside the Beltway to around freezing downtown. Confidence: Medium

Tomorrow (Saturday): Periods of snow or snow and rain are possible through about midday. There’s a lot of uncertainty about how quickly any storm develops as it finishes passing by, which could have sizable impacts on what we expect for the day. Highs in the 30s is about best for now, as we could end up near or just above freezing much of the day or perhaps into the low 40s in spots if the storm doesn’t come together right. One kicker, though, is moderate northwest winds in the 10-20 mph range could actually gust a bit higher late in the afternoon. Don the scarf, perhaps. Confidence: Medium

Tomorrow night: Winds should die down and skies partially clear, allowing remaining snow to effectively ice-down our temperatures into the teens for most spots, perhaps around 20 downtown. Confidence: Medium

Sunday: May feature substantial cloud cover along with a few flurries (20-30% chance) or snow showers that dust us briefly, at least on top of the existing snow cover. High temperatures in the upper 20s to low 30s are probable. If we see more sunshine break through, mid-30s might be possible. Confidence: Low-Medium

A LOOK AHEAD

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

6 (↓) Perhaps the colder suburbs get over an inch from wet snow showers tonight, but downtown may only get a dusting.

Sunday night: Mainly clear and mainly cold! Low temperatures are in the teens to low 20s. But snow cover could maintain itself enough, even downtown, to chill us a bit colder than I currently expect. Confidence: Low-Medium

Monday’s Presidents Day skies GLADLY show us some sunshine. Get out and enjoy, especially if you have the day off. Dine al fresco with high temperatures in the mid-30s to low 40s and perhaps little in the way of wind. Kidding about the al fresco, obviously. But all in all, not too shabby. At least until early evening when clouds perhaps move in with some mixed rain/snow showers? Confidence: Low-Medium

Tuesday’s conditions depend on whether we can (struggle to) get below freezing around sunrise for some wintry weather, with rain showers perhaps continuing for some of the day. We’ll have to watch it, with substantial uncertainty this far out, if temperatures do safely rise into the 40s or even near 50, quelling any mix concerns. Confidence: Low
