Sherry Lynn, owner of The Atrium on Route 422, said she looked outside her business around 1:30 p.m. Monday, Jan. 19, to see the aftermath of a crash.

“I didn’t see the accident occur, but I saw one of the vehicles hit the bank of the road. I ran over to check on him and called 911,” she said.

The crash, which involved a plow truck and another vehicle, ultimately resulted in the closure of the route between Dick Road and Old Route 422. A medical helicopter was also called to the scene.

The crash was one of over a dozen reported across Butler County on Monday as snow squalls battered the region.

Meteorologist Matt Brudy with the National Weather Service in Pittsburgh said the county was pelted with multiple snow squalls — intense bursts of heavy snow and gusty winds that lead to quick snow accumulation and rapidly falling visibility — throughout the morning and early afternoon.

“People are going from driving with no snow visible to having their visibility drop and the roads coated,” he explained.

Brudy said the service issued several squall warnings early Monday before the last expired at 1:15 p.m. He said all in all, the squalls likely only caused half an inch to an inch of accumulation.

Regardless, the weather was prevalent as crashes occurred across the county, impacting traffic along several major roads.

Other than the Route 422 closure, Butler County Emergency Services dispatch reported a two-vehicle crash around noon at the intersection of Routes 8 and 228 West in Middlesex Township, causing traffic delays in the area.

A representative for Butler County Emergency Services dispatch said between midnight and 3 p.m. Monday, crews were dispatched to a total of 20 crashes. He said crashes were mostly sporadic, except on Interstate 79, which seemed to have the most crashes.

According to prior dispatches, two rollover crashes were reported along the interstate around 11:30 a.m. and 12:30 p.m.

Brudy said the county is not expected to get any significant snowfall on Tuesday, but will have to deal with low temperatures throughout the week. A cold weather advisory was set between 9 p.m. Monday and noon Tuesday.

“It’s going to be cold tonight, with wind chills dropping into the negative teens. It’ll take some time to warm up even after daytime and it might be after noon before we see temperatures rise to feel like above 0 again,” he said Monday.
