The Winter storm expanded for most of Northern Virginia

The National Weather Service extended its winter storm warnings overnight, with more snowfall now expected.

Monday, a winter storm warning began at 1 am for eastern Arlington, Alexandria, Fairfax, Prince William, Stafford, Fouquet, and Loudon counties. Forecasters call for 12 inches of snow for most of the metropolitan area and the south, with occasional heavy snowfall and winds of up to 35 miles per hour.

The National Weather Service estimates starting times for snow on Monday.

Unlike a watch, which means severe weather is possible, a warning means severe weather is imminent. The notice ends at 4 pm. Monday.

The Sterling National Weather Service's high-end snow map shows approximately 8-14 inches of potential snow under some storm models.

The National Weather Service says the coastal low-pressure system moving tonight through Monday will bring temperatures between the 20s and low into the 30s. This dip has trended north and west over the past 24 hours, resulting in the potential for heavy snowfall, especially from the capital to the southern suburbs.

High winds associated with a storm may cause snowdrifts.

Rainfall is expected to start as rain by 3 am for most of the area, turn into snow and continue into Monday afternoon.

The weather service says forecasts continue to change and urges area residents to stay on top of updates throughout the day.

The Virginia Department of Transportation asked the crews working all night on Northern Virginia roads and will start plowing when the snowfall reaches two inches. State police said they plan to deploy additional forces during the storm period.

The weather service says that traveling can be challenging under dangerous conditions that affect your commute in the morning.
