The National Weather Service in Baltimore/Washington has issued a severe thunderstorm watch effective until 10 PM EDT today, spanning multiple counties across Maryland, Virginia, and parts of West Virginia. This hazardous weather outlook warns of potential large hail and damaging wind gusts, particularly affecting the Chesapeake Bay, Tidal Potomac River, and the Interstate 95 corridor through central Maryland, northern Virginia, and the District of Columbia.
Residents in the impacted areas, including major cities like Baltimore, Washington D.C., and Alexandria, are advised to prepare for scattered severe thunderstorms which could produce hail approximately 2 inches in diameter and strong wind gusts. The storms are likely to occur mostly along and south of Interstate 66 and Highway 50.

The warning includes the following areas: all of the District of Columbia; ten counties in central Maryland such as Anne Arundel, Howard, and Prince Georges; three counties in southern Maryland; and a large portion of northern and central Virginia, including the cities of Arlington and Charlottesville. This broad region should brace for potentially severe weather conditions that could disrupt evening routines.
For those in the specified regions, it’s crucial to stay updated with the latest weather forecasts and follow any safety instructions issued by local authorities. The hazardous weather conditions may lead to significant disruptions, including damage to property and potential hazards on the roads due to high winds and poor visibility.
This weather event underscores the volatile spring season in the Mid-Atlantic, where changing conditions can swiftly lead to severe weather patterns. Community members are encouraged to secure outdoor objects that could be displaced by high winds, seek shelter indoors during the storm, and avoid water bodies like the Chesapeake Bay and the Tidal Potomac River where gusts may be particularly strong.
