On this day in 1999, a major hail storm swept from Waynesburg, PA, through the WV Panhandle, into VA, passing through the western and southern suburbs of Washington, DC, crossing into Maryland, where it moved across the Chesapeake Bay, and finally out to the Atlantic Ocean. Along the 305+ mile-long path, hail up to baseball size fell, and $75,000,000 in damage occurred as numerous cars and homes were damaged or destroyed. Source.
