Gray, wet week ahead for Butler County
After flash flooding affected parts of Butler County on Friday, this week is expected to bring little relief from the wet weather.
Following a sunny Sunday, forecasts from the National Weather Service call for four straight days with a 60% or higher chance of rain, starting Monday, Aug. 10 and lasting through Thursday, Aug. 13. The sun is not expected to break through until Friday, when forecasts call for mostly sunny weather and temperatures in the high 70s.
Although the rain is not expected to be completely non-stop over the four-day period, according to meteorologist Alicia Miller of the National Weather Service in Pittsburgh, the breaks should be short-lived.
“There’s potential for breaks in the rain, but not very long... maybe six hours,” Miller said.
The most severe weather is predicted for Monday, with forecasts of thunderstorms bringing potential gusts of wind as high as 21 miles per hour.
“We’re going to be in an active period of storms that could produce flash flooding,” Miller said. “Our biggest concerns are severe wind gusts and flash flooding.”
Since the start of this summer on June 21, just over 11 inches of rain has fallen on Butler County, according to data collected by the Slippery Rock weather station. This is nearly triple the amount of 4.06 inches that fell on Butler County over the same one-and-a-half month period in 2025.
On Friday, flash flooding closed Herman Road and wreaked havoc on homeowners in Jefferson Township. Residents along Thorn Creek in Jefferson Township spent Friday late afternoon and evening cleaning their basements.
Though unsurprised by the water levels, residents like Chuck Beikert said the water rose faster than they’d seen before.
On July 5, Slippery Rock Mayor Jondavid Longo had declared a disaster emergency as rain fell fast and flooded streets, businesses, and homes in the borough.
