Baltimore, Maryland – A high-impact winter storm is expected to move into Maryland, Washington, D.C., and northern Virginia this weekend, bringing a combination of heavy snow and ice that could make travel dangerous from Saturday night into Sunday morning.
According to the National Weather Service Baltimore/Washington office, snow is expected to spread into the region Saturday evening from southwest to northeast, with the heaviest snowfall developing overnight. Many inland areas of Maryland, including Frederick, Carroll, Washington, and western Baltimore counties, could see plowable snowfall with several inches accumulating before daybreak Sunday. Confidence is high that the region will see impactful winter weather, though exact totals remain uncertain.
Forecast guidance shows the potential for significant snow totals north and west of the I-95 corridor, while areas closer to southern Maryland and the Chesapeake Bay could see snow mix with sleet or freezing rain Sunday. Ice accumulation is a growing concern south and east of Washington, including parts of Charles, St. Mary’s, and Calvert counties, where even a glaze could lead to slick roads, downed tree limbs, and scattered power outages.
The Maryland Transportation Authority warns that untreated roads, bridges, and ramps could become hazardous quickly overnight Saturday. Drivers are urged to avoid non-essential travel, especially during the peak of the storm.
Wintry precipitation is expected to taper Sunday, but colder air moving in behind the system could allow refreezing into Sunday night. Winter Storm Watches remain in effect, and warnings or advisories may be upgraded as confidence in snowfall and ice amounts increases.
