The snowfall ended and warmer weather is just days away, but not before a couple more potentially treacherous morning rush hours.
Between four and 10 inches fell from Sunday evening into Monday afternoon throughout the Washington, D.C., metro area, accumulating quickly, according to Storm Team4.
This is the most snow the District has seen this entire winter season.
With temperatures back below freezing, some areas of snow and slush froze overnight. Roads will be slick in spots Tuesday morning.
Several Virginia school districts have called for two-hour delays Tuesday after being closed Monday.
Light freezing rain is more likely again Wednesday morning along I-66, I-270 and I-70 including Fredericksburg, Gaithersburg and Leesburg. That should turn to rain from about noon until 7 p.m.
Federal offices in the D.C. area also were closed Monday, and employees were asked to follow their agency's telework procedures.
Virginia State Police responded to 359 traffic accidents and 228 disabled vehicles statewide by 11:30 a.m., including a bus crash on I-95S in Stafford County that injured four passengers.
Meanwhile, area road crews hit the streets. D.C. crews had more than 200 plows on the job. The Virginia Department of Transportation said their crews mobilized at 6 p.m. Sunday.
Officials said the main runway at Ronald Reagan National Airport outside Washington re-opened at 9 a.m. Monday after being closed for several hours. Residual delays and cancellations are expected to continue throughout the day.
At Washington Dulles International in Virginia, three runways are open. Airlines canceled some morning flights due to the storm and additional cancellations and delays are expected.
Officials with the Baltimore-Washington International Thurgood Marshall Airport also said snow has affected some flights, and winter weather is expected to cause flight delays or cancellations.

The D.C. Department of Public Works said normal rush hour parking restrictions were in place Monday and enforced from 7:30 a.m. to 9:30 a.m. and 4 p.m. to 6 p.m.
MARC trains and VRE operated on an "S" schedule Monday.
This is not -- by a long shot -- the latest that D.C. has seen snow. In 1898, D.C. saw a half-inch of snow April 28, according to records kept by the National Oceanic and Atmospheric Administration.
Just last year we had a trace of snow on the ground March 18 -- and saw 1.4 inches March 25.
But this latest storm comes after a brutal winter, with 23.1 inches of snow recorded so far in D.C. The average is usually around 15 inches.
Ronald Reagan National Airport has seen snow on 15 days this winter for a total of 30.3 inches. Dulles International Airport has had 19 days of snowfall for 47.9 inches, and Baltimore Washington International Thurgood Marshall Airport has had 17 days for 35.6 inches.
We've also suffered through days of painful cold that led to big heating bills and scrambled school calendars. Last week, Montgomery County, Md., schools recorded their first full week of school since the holiday break.
Other schools have said they would have to limit recess, extend the school day or ask the state for an exception to laws that require a certain number of instructional days.
The weather will be warmer for the weekend, with temperatures reaching the 60s, but those could fall back to highs in the 30s and 40s early next week.
