Storms brought damaging winds, large hail and flooding across the state Thursday afternoon, with more possible later in the evening as a cold front approaches.
Wind damaged a building on Route 1 in College Park, and hail an inch in diameter was reported in the Hereford area of Baltimore County, according to early storm reports made to the National Weather Service. A flood warning was issued in the Jarrettsville area of Harford County.
A cold front advancing toward the region and meeting the hot, humid air is expected to fuel the storms.
The forecast threatened to spoil some early Fourth of July festivities. The Baltimore Symphony Orchestra canceled the first of two concerts at Oregon Ridge Park after consulting with meteorologists, spokeswoman Eileen Andrews said. The BSO will honor tickets purchased for Thursday night's concerts at one scheduled to go on at 8 p.m. Friday.
In College Park, a portion of a roof of a 7-story apartment tower was blown off by wind and was laying across Route 1, briefly closing the road in both directions, according to Prince George's County fire spokesman Mark Brady and University of Maryland officials.
Clear, sunny skies, low humidity and highs in the mid-80s are forecast Saturday and Sunday.
