Another snowstorm could drop 2-4 inches more snow on the Washington, D.C., area, overnight as the region continues to deal with clogged, icy and messy streets left by Monday’s storm — and wind chills in the teens will make for frigid weather Friday.

A winter weather advisory is in effect throughout D.C., Maryland and Northern Virginia through 5 a.m. Friday. Frederick County, Maryland, is under a winter storm warning until 4 a.m.

The U.S. Office of Personnel Management announced federal offices in the D.C. area will be closed Friday.

Numerous public schools will be closed Friday, including those in D.C.; Alexandria and Manassas cities; and Arlington, Fairfax, Loudoun, Spotsylvania, Stafford, Prince William and Culpeper counties. Go here for the latest school closures.

Snow chances ramp up after dark and continue into early Friday, Storm Team4 says.

The heaviest snow is set to fall overnight. Snowfall rates could briefly reach 1 inch per hour.

Snow totals may reach up to 4 inches, but 2-3 is most likely near D.C. In higher elevation areas, such as the Shenandoah mountains, closer to 6 inches is possible.

Accumulating snow promises delays, closures and travel trouble even after it stops falling early Friday morning.

Virginia Gov. Ralph Northam declared a state of emergency Wednesday night ahead of the second round of snow.

“Having two bouts of snow and icy weather back to back makes it more likely communities will need additional help as they continue to recover from the first round of tree-snapping wet snow and ice that we saw Monday,” Northam said in a statement.

Metro said Thursday that service on some bus routes will be suspended.

Some COVID-19 vaccination centers in Fairfax and Prince William counties and Fredericksburg, Virginia, will be closed Friday due to the weather, The Virginia Department of Health said.

People who were trapped for hours on Interstate 95 in Stafford County after the snowstorm speak with News4's Drew Wilder.

Monday brought the biggest snowstorm that D.C., Maryland and Virginia have seen in years. Several school districts were closed on Thursday. More than 100 roads remained closed in the Fredericksburg area on Wednesday.

DC Area Weekend Forecast

The snow will end early Friday morning and a gusty northwest wind will bring back the sunshine before noon.

Friday will be cold. Temperatures will struggle to get above freezing before dropping into the teens and low 20s by Saturday morning.

Icy roads will be a major concern. Limit travel if possible, and go slow if you must go out.

Storm Team4’s next big weather concern comes Sunday.

There’s an 80% chance of rain, which may start as sleet or freezing rain.

A strong cold front Sunday evening will turn off the rain, but send temperatures plunging by Monday morning. Icy roads could make for more treacherous travel.

Get your warm winter layers ready for next week. We’ll have biting cold temperatures and highs only in the 30s through Wednesday.
