Parts of southern Allegheny County, including West Mifflin, Elizabeth Township and Baldwin Borough, are under a severe thunderstorm warning through 5:30 p.m., meteorologist Bill Modzelewski from the National Weather Service in Pittsburgh said in an alert update.
Conditions are ripe for some severe weather throughout the evening, the NWS says.
Jon Darnley, a meteorologist, said a severe thunderstorm watch was put into effect at 1:20 p.m. through 8 p.m. for all of Western Pennsylvania.
"The atmosphere has the potential for producing severe weather," Mr. Darnley said, noting that this is typical for this point in the summer.
The watch is anticipating the possibility of high winds, lots of rain and some hail. One way or another, though, the rain is coming. Mr. Modzelewski said the heavy rain might let up earlier than expected, as some of the storms are already beginning to move east.
