Baltimore, Md. – Low clouds and muggy air will give way to showers and thunderstorms across Maryland and the D.C. metro Wednesday afternoon, bringing the potential for heavy downpours and localized flooding.
According to the National Weather Service in Baltimore/Washington, storms will be most active late Wednesday into the evening, especially west toward the Alleghenies. As Hurricane Erin tracks well offshore, its influence will push strong northeast winds into the region Thursday, creating a growing risk of tidal flooding along the Chesapeake Bay and tidal Potomac.
High temperatures will climb into the upper 80s around Baltimore, Washington, and Fredericksburg Wednesday, while mountain areas remain closer to the low 70s. Breezy conditions Thursday could drive water levels above normal along Annapolis, Solomons, and other coastal communities. Motorists near low-lying roadways should be alert for water covering pavement during high tide cycles.
After a drier Friday under high pressure, storm chances return west of U.S. 15 on Saturday before spreading more widely on Sunday. Travelers along I-70 and I-95 may encounter reduced visibility and ponding water as storms redevelop.
The National Weather Service warns that additional advisories could be issued through the weekend, particularly for tidal flooding and heavy rainfall.
