A coastal storm is expected to bring significant snowfall to the Washington, D.C. region Sunday night into Monday morning, prompting Winter Storm Warnings across portions of Maryland and Virginia. The National Weather Service has issued warnings for Frederick, Montgomery, Calvert, St. Mary's, Anne Arundel counties in Maryland and Loudoun County in Virginia. Maryland Governor Wes Moore declared a State of Preparedness Saturday night, directing emergency management to coordinate readiness efforts.

Precipitation will begin as rain Saturday night before transitioning to snow Sunday evening as colder air moves in from the northwest. Current projections indicate Washington, D.C. could see 3-6 inches of snow, with higher totals possible in northern Maryland and lower amounts farther south and west in Virginia. Eastern Shore areas are likely to see the most accumulation. The storm's exact track and strength remain uncertain, with temperature variations of just a few degrees potentially affecting final totals significantly.

Wind gusts up to 30-40 mph are expected inland, with higher gusts near the Chesapeake Bay. The heaviest snowfall is forecast Sunday night through early Monday, potentially creating hazardous travel conditions during the Monday morning commute. Unlike January's deep freeze, warmer temperatures next week should help melt snow more quickly, limiting long-lasting impacts.
