Winter weather looming as snow, ice could make travel hazardous in DC area

The D.C. region wakes up to wintry weather as another storm passes by and stays until the end of the week. Here’s what to know.

The D.C. region will wake up to wintry weather as another storm passes by and stays until the end of the week. A winter storm warning is in effect for the area through 6 a.m. Friday.

Here’s what you need to know.

  • DC-area schools announce Thursday changes. Some school systems still have virtual learning, while others are calling it a full snow day. See all closings and delays here.
  • Metrobus schedule changes for Thursday. The bus system will operate on a moderate snow plan; Metrorail won’t be affected.
  • When is snow coming? Snow arrives around midnight Thursday, changing to sleet or freezing rain from D.C. to points east and south by early afternoon. Storm tapers off late Friday morning.

Like the last few storms, the rain-snow line will move northward during the storm, bringing the potential for a significant accumulation of ice over parts of the area, Storm Team4 meteorologist Mike Stinneford said.

Precipitation will stay mostly snow over the northern and western suburbs, and change over to rain over southern Maryland.

“There will be the potential for several inches of snow over the immediate metro area, followed by ice,” Stinneford said.

Starting from the southwestern suburbs overnight, the entire region will see snow, between 1 to 3 inches, before sunrise Thursday.

The snow will mix with ice throughout the day, and at night, much of the area will see snow and ice, as temperatures cool below freezing, with the precipitation mixing with or changing to rain before ending on Friday.

Snow amounts of 2 to 6 inches are possible before the changeover to ice in the immediate D.C. area; 6 to 10 inches of snow north and west; and 1 to 2 inches possible in southern Maryland.
