A tornado warning was issued for parts of Anne Arundel, Prince George's and Howard counties, including Laurel, Beltsville and Elkridge, as a severe storm moved through the region.
The warning was in effect until 1:30 p.m.
As much as 1-3 inches of rain could fall across the region Wednesday amid stormy weather that previously prompted a tornado warning in Washington, D.C. A flood watch is in effect for much of the Baltimore area.
The National Weather Service issued a tornado warning at 12:23 p.m. for southeastern Washington and parts of Prince George's County and Arlington and Alexandria in Virginia. Radar indicated possible tornado rotation near Fort Hunt in Northern Virginia, according to forecasters. The tornado warning was canceled about 15 minutes later.
The flood watch covers Howard, Anne Arundel and southern Baltimore counties and Baltimore City through 8 p.m., according to the National Weather Service. Low lying areas, particularly in urban areas, are prone to flooding, forecasters cautioned.
Storms are possible throughout the day, though they are not likely to be severe.
Rain and warmth could linger into Thursday, with chances for showers in the morning and highs again in the mid-70s.
Cooler, drier air is expected to move in by Friday for the weekend, with lots of sunshine. Highs are forecast in the lower 70s and upper 60s Friday and Saturday, and the lower 60s by Sunday.
