Butler County can look forward to slightly warmer temperatures and less precipitation this weekend, but that did not help Tuesday during a snowstorm.

The National Weather Service in Pittsburgh measured 4 inches of snow in Saxonburg, 3.5 inches in Evans City, 2.9 inches in Cranberry Township, 2 inches in Slippery Rock and 3 inches in Freeport.

There were a few vehicle accidents Tuesday morning as snow started to move across the county.

One man was injured about 6:30 a.m. when he crashed his vehicle into a hillside on the 500 block of Sarver Road in Buffalo Township.

The man was bleeding from the head when emergency crews arrived at the scene, according to 911 reports. He was taken to Allegheny Valley Hospital by ambulance.

Another accident occurred in Buffalo Township on Route 28 near Exit 17 about 7:45 a.m. A woman was taken to Allegheny Valley Hospital with a hand injury.

Traffic on Interstate 79 was tied up when a southbound tractor-trailer jackknifed near mile marker 94 in Muddy Creek Township about 10:20 a.m.

The rig crashed into the center median, according to dispatch reports. One person was taken to Butler Memorial Hospital.

While the snow made morning commutes difficult, there wasn’t an unusually high number of emergency calls related to the weather.

“It’s been a standard, snowy Tuesday morning,” said Steve Bicehouse, director of county emergency services.

Bicehouse said the 911 center was busy with the accidents and notifications to road crews, but said it was typical for a winter day.

“Nothing has been too taxing yet,” he said.

There were multiple other minor accidents early in the afternoon, according to 911 reports.

The weather service issued a winter weather advisory for the county until 7 p.m. Tuesday. Wind gusts of up to 30 mph caused white out conditions at times in Western Pennsylvania.

In addition to the morning snow, a heavy snow squall in the afternoon recoated roads that previously had been treated.

Bob Skrak, maintenance manager in Butler County for the state Department of Transportation, said his crews did a good job with the storm.

“I think we kept ahead of it,” he said. “It came in waves. By the time we got it cleaned up, they had to go right back out again.”

Skrak said plow truck drivers started about 1 a.m. Tuesday and worked in 12-hour shifts.

Josh Clinger, PennDOT manager in Clarion County, said his crews were busy with Interstate 80 during the day.

PennDOT reduced the speed limit on Interstate 80 to 45 mph from the Ohio state line through to State College due to white out conditions.

But Clinger said he thinks the crews kept the roads clear.

“So far so good,” he said mid afternoon. “I think we’ve handled the storms well.”

Clarion crews handle the highway from exit 42 in Emlenton to exit 70.

David McDeavitt, superintendent with the A-C Valley School District, said buses didn’t have too much trouble with the roads.

“We had a couple buses come in a little late,” he said. “But we ask our drivers to slow down if the roads are bad.”

McDeavitt said all evening activities for the school were canceled, but said the weather wasn’t too disruptive.

“It was a typical Western Pennsylvania day,” he said.

This morning the Freeport and Butler school districts had a two-hour delay because of the cold.

Tonight, an additional inch of snow is possible. On Thursday, the temperature is expected to be in the low 30s.

The temperature will be in the low 40s on Friday, with rain possible. The precipitation will change from rain to snow Friday night with little or no accumulation predicted.

The rest of the weekend includes possibilities of rain and snow with little or no accumulation expected.
