UPDATE: 5 a.m. on Sunday, March 16

The National Weather Service has issued a winter storm warning for the D.C. area from 7 p.m. Sunday afternoon through 2 P.M. Monday afternoon.

Howard, Carroll and Frederick, Md. counties remain under a winter weather advisory.

Evening will begin with rain and sleet until turning into snow overnight. There could be up to six inches of snow by Monday afternoon, depending on location.

It will be in the lower- to mid-40s Sunday afternoon, and the temperature is expected to drop into the lower to mid-20s across the region by nightfall. The high will be in the lower 30s by Monday. Winds could gust up to 20 miles per hour.

Forecast as of Saturday p.m.


ABC7 meteorologist Alex Liggitt is predicting 2 or more inches will fall in parts of the region by Monday morning. Snow will fall over the region Sunday night into Monday morning and showers are possible throughout the day Monday.

The snow will cause travel delays and possibly cancellations Monday.

Areas north and west of the District including Loudoun and Frederick counties will see the greatest chance for measurable snowfall. Areas south and east of D.C. including Stafford, Fredericksburg and Southern Maryland will have a greater chance for a snow-rain mix so residents in these areas can expect less snow accumulation.

The immediate D.C. metro area also has a chance for snow but temperatures will determine just how much the urban core will see.

National Weather Service

The National Weather Service is predicting accumulating snow with the heaviest snow falling late Sunday night into early Monday morning. The snow could linger throughout the day Monday, says meteorologist Brian Lasorsa.

Temperatures will be in the 40s Sunday ahead of the storm system but will drop into the upper 20s and lower 30s over night. Monday temperatures will be in the mid 30s, Lasorsa says.

The storm will begin as rain then move to a snow/mix before changing to all snow. However the service is not predicting accumulation totals yet, he says.

Weather Channel

The Weather Channel has a forecast that will send snow lovers headed to the nearest ski resort.

Weather Channel forecasters are predicting as much as 4 inches of snow along the Interstate 95 corridor including portions of Northern Virginia, D.C. and Maryland.

Mountain areas in both Western Virginia and Western Maryland could see more than six inches of the white stuff.

The snow will begin as rain and will cause poor travel conditions overnight and for both the morning and afternoon commutes Monday.
