Winter storm warning expanded for most of Northern Virginia – Inside NoVA

The National Weather Service has expanded its winter storm warnings for overnight, with up to more snow now in the forecast.

A winter storm warning begins at 1 a.m. Monday for Arlington, Alexandria, Fairfax, Prince William, Stafford, Fauquier and eastern Loudoun counties. Forecasters are calling for three to seven inches of snow for most of the D.C. area and south, with snow heavy at times and wind gusts up to 35 mph.

National Weather Service estimated start times for Monday snow.

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

The National Weather Service Sterling forecast office high-end snow map shows nearly 8-14 inches of snow possible under some storm models.

A coastal low pressure system moving through tonight into Monday will drop temperatures into upper 20s and low 30s, the National Weather Service says. That low has trended north and west over the last 24 hours, bringing potential for heavy snow, particularly from D.C. into the southern suburbs.

Gusty winds accompanying the storm could cause drifting and blowing snow.

Precipitation is expected to start as rain by 3 a.m. for most of the region, turning to snow and continuing through Monday afternoon.

The weather service says the forecast continues to change and urges area residents to stay on top of updates through the day.

The Virginia Department of Transportation will have crews staging overnight on Northern Virginia roads and will begin plowing when snowfall reaches 2 inches. State police said they plan to have extra troopers on patrol for the duration of the storm.

The weather service says travel could be very difficult with hazardous conditions impacting the morning commute.
