- Between a trace and an inch of snow is still possible before noon, but chances of anything more substantial are rapidly dwindling.
- Falling temperatures and single-digit wind chills will lend to a refreeze overnight. Additional school delays or cancellations are possible.

Commuters can breath a sigh of relief: Rush hour snow didn’t materialize for most of the D.C. region on Thursday, yielding instead to a cold and steady rainfall.
The National Weather Service has dropped its Winter Weather Advisory. Little to no accumulating snow is forecast outside of Northern Maryland, and even there, snow totals aren’t expected to exceed an inch on grassy areas. A brief snow shower is possible in D.C. and Baltimore before precipitation finally tapers off around noon.
“Temperatures have remained above freezing and minimal snow accumulation is expected,” the weather service said in its Thursday morning update.
But while the forecast trended favorably, commuters are still faced with a risk of black ice amid plummeting temperatures this afternoon and tonight. Crews are having to retreat roads due to rain having washed away de-icing solution.
Drive slow, leave plenty of stopping distance from the vehicle in front you, and be extra cautious on driveways, highway ramps, bridges and overpasses.

The Virginia Department of Transportation spent much of Wednesday pretreating major roads with a salt brine solution in anticipation of both Thursday’s winter weather and Friday’s refreeze. District officials will have the city’s snow team on full deployment during Thursday morning rush hour to salt roads.
“If travel is unavoidable and absolutely necessary, drivers must plan to complete travel before snowfall begins and remain off the roads until they are passable,” VDOT said in a news release.

Snow wanes to flurries around noon, after which attention shifts to blisteringly-cold temperatures and wind chills due to persist through the weekend. Believe it or not, Thursday morning’s forecast highs in the 30s might be the warmest it’ll get until at least Sunday: Thursday night’s lows will be in the teens, while Friday and Saturday highs aren’t likely to climb out of the upper 20s.
Computer models, meanwhile, continue to shy away from snow chances early Saturday. A developing low over the Tennessee Valley will bring more snowfall to the Carolinas and portions of central and southern Virginia, but the worst of it looks to stay well outside of the WTOP listening area.
“In those areas south of D.C., 2 to 3 inches are not totally out of the question, but it is unlikely that anyone around the D.C. region will get much more than an inch,” Bell said. “There is still time to watch, but this does not look like a major event in our area.”
