Snow is still on the ground across the D.C. region Sunday morning, and it’s not going anywhere as bitter cold air settles in.
A flash freeze advisory is in effect throughout the D.C. region Sunday as temperatures drop rapidly following the morning’s snow storm.
WTOP Meteorologist Mike Stinneford said roads are becoming slick as any slush and standing water is rapidly turning into ice.
A Winter Weather Advisory has been canceled, but the issue for the rest of Sunday will be the cold and the wind.
“Black ice will continue to be a problem on area roadways with temperatures in the 20s, and wind chills in the single digits and teens,” Stinneford said.
He said this will be an issue for the rest of Sunday morning and into the afternoon. Reports show 1 to 3 inches of snow fell along and north of I-70 early Sunday morning, according to Stinneford.
Charlie Gischlar, the deputy director of communications with the Maryland State Highway Administration, is advising people to stay off the roads if you can. But if you do drive, take it slow on ice and snow, he told WTOP.
Remember, “the speed limits are set for dry conditions, and these won’t be dry conditions overnight. They’re going to be snowy,” he said. If you see some of his agency’s “snow plow drivers or contractors, stay behind them, because they’re literally clearing a path for you.”
Prepare for a possibly icy commute Monday morning, Gisler said. But he added that Maryland roads will be prepared. The state has about “100 trucks that have mobile infrared sensors so we can tell when a road’s about to freeze up. And we can go and strategically deploy the trucks and treat the roadways before they freeze,” he said.
Temperatures will fall through the 20s, with wind chills in the single digits and teens.
It will remain cold out there as the day goes on: Temperatures are around or just above freezing, which means main roads may become slushy and some areas may become icy as temperatures fall below freezing over the next few hours, Stinneford said.
Pay special attention to bridges, overpasses, exit and entrance ramps, and untreated secondary roads, he said.
The Maryland Transportation Authority said a Wind Warning was under effect for the Governor Harry W. Nice Memorial/Senator Thomas ‘Mac’ Middleton Bridge Sunday morning starting around 8 a.m., urging house trailers, vehicles with roof-mount racks, motorcycles and box trailers to use caution.
“Be very careful on elevated roadways,” said 7News First Alert Meteorologist Mark Peña, warning about accumulating ice on the road.
“No matter how much snow you see, it’s not only going to stick around for the rest of Sunday but for most of Monday,” said Peña, adding that Sunday night will mark the coldest night of the season so far.
By Monday morning, temperatures will be in the teens as people head out the door, with wind chills close to zero.
Transportation agencies continue to urge drivers and pedestrians to use extreme caution, especially on secondary roads and sidewalks where snow and ice may linger.
Temperatures will finally climb back above freezing by Tuesday.
Last week, the first snowstorm hit the D.C. region in December for the first time since 2017.
