The National Weather Service in Pittsburgh predicts more rain and possibly thunderstorms to hit Butler County this weekend, but they are expected to be less severe than some recent storms.

David Shallenberger, meteorologist with the weather service, said Friday, June 19, showers and scattered thunderstorms are expected to arrive in the region Saturday afternoon.

He said daylight hours for Sunday are expected to be warm and dry, with a high in the high 70s, before a new system arrives that evening.

Shallenberger said showers and possible thunderstorms will return to the region Sunday night and will continue all day Monday, leaving behind over an inch of estimated rainfall in about 24 hours.

Despite the continued rains Saturday, Sunday and Monday, the weather service does not expect severe weather or flooding from the upcoming system as of Friday.

Butler County has faced several storm systems over the past weeks, with the worst being on Sunday when two tornadoes touched down.

One tornado touched down on the western portion of the North Shore of Moraine State Park and was rated EF1; while the second, rated EF0, touched down near the intersection of Muddy Creek Drive and Route 8 in Center Township.

Emergency services responded to 28 calls for downed trees and power lines within a 2.5-hour period during Sunday’s storm and more than 800 residences were left without power Monday morning.

Another system came through the area Wednesday night into Thursday, resulting in strong wind gusts that caused numerous downed trees and power lines once again.

FirstEnergy said in a Wednesday news release they activated its incident command structure and were mobilizing additional workers to respond and restore service quickly.
