Storms and heavy rain are forecast again Thursday night, with an outside chance of more damaging winds and large hail.
A warm front is moving up from central Virginia bringing humid air back into the region. That is expected to create instability in the atmosphere ahead of a stormy system moving eastward from the Ohio Valley, according to the National Weather Service.
More than an inch of rain is forecast in Baltimore, which would make this the region's wettest June on record with more than 10 inches of rainfall possible. So far, 9.57 inches of rain have fallen at Baltimore-Washington International Thurgood Marshall Airport, the region's point of record.
The weather service's Storm Prediction Center includes Maryland in a region with "slight" chances for severe weather, with 15 percent chances for damaging wind and large hail, and 2 percent chances for isolated tornadoes. But the weather service's Baltimore/Washington forecast office notes that the strongest risk for severe weather in the mid-Atlantic is in central Virginia.
Storms are expected to move from west to east from late afternoon into this evening.
More rain and storms are forecast Friday and Saturday.
