Strong, scattered thunderstorms that blew through several Southwestern Pennsylvania counties this morning, some bringing gusts of up to 40 mph and pea-sized hail, have moved south.
A National Weather Service severe thunderstorm warning for Allegheny County expired at 8:30 a.m. but another warning for parts of north central West Virginia and eastern Maryland is still in effect.
Earlier today, the weather service said storms have been reported in -- or were expected to hit -- parts of Allegheny, Beaver, Butler, Greene counties.The isolated thunderstorms, riding along a warm front from Lake Erie to West Virginia, were expected to taper off by late morning.
The afternoon high temperature is expected to reach 76 degrees under partly sunny skies, the weather service predicted.
Lightning struck a tree on Jamison Lane in Monroeville around 8:15 a.m., went down a fence and caused a home there to catch fire, an emergency dispatcher said. No one was injured. The Allegheny County fire marshal's unit was on the scene.
