A second round of winter weather blew through the D.C. area early Tuesday, prompting the closure of the federal government and local school systems and leaving a blanket of snow in advance of what could be a slippery evening commute.
National Weather Service officials said the storm had mostly passed by late morning.
“There are still a few bands of light snow, but the heavy stuff is pretty much out of here,” Weather Service meteorologist Jason Elliott said. “The fact is, we could see an icing of what’s out there. Even if the roads are just wet, if there’s water left on the roads, when it drops below freezing there could be some icing.”
Mr. Elliott said the temperature is expected to drop to 23 degrees in the District, and as low as the teens in the suburbs.
“It’s not going to be any warmer,” he said. “We will get some sunshine but it looks like it will be on and off tomorrow and on and off again Thursday. The temperatures are not going to get much above freezing, even during the day.”
Tuesday’s storm moved into the D.C. area around sunrise, with sleet turning into fast-falling snowflakes within minutes. Mr. Elliott said about 2 inches of snow fell at Washington Dulles International Airport, while the District and inside the Beltway saw between 1 and 1½ inches of snow.
“Just southeast and south of the District, precipitation stayed mainly in the form of rain, with a little bit of sleet,” Mr. Elliott said. “A lot of it was in the form of really cold rain, so the south and east only got flurries.”
Mr. Elliott said some areas closer to the West Virginia panhandle had a total of 6 inches of snow, the result of a combination of Tuesday’s storm and Sunday’s wintry mix.
Maryland State Highway Administration spokeswoman Sandra Dobson said 1,800 trucks and plows had been working overnight to keep the roads clear and as of Tuesday morning “we’re quite pleased right now.”
“The roadways are wet but certainly passable,” she said. “There’s no accumulation though we still have some concerns about the terrain in western Maryland. But even there trucks are moving along well now.”
Ms. Dobson said road crews would continue to monitor the weather and prepare for salting to fight an overnight icing.
About 7,000 power outages remained in Northern Virginia, mostly the result of the ice storm Sunday.
