Lorrie Barkley uses her snowblower this morning along Main Street in Saxonburg after a winter storm dumped five inches of snow in the borough. Other communities reported up to seven inches, while ice also accumulated in some municipalities.

Four to seven inches of snow, along with freezing rain, covered Butler County overnight, shuttering schools and snarling roads.

“In addition to all this snow, we do have reports of a tenth to a quarter inch of ice,” said Joe Palko, a meteorologist with the National Weather Service's Pittsburgh office.

The National Weather Service reported seven inches accumulation in Cabot, six inches in Cranberry Township, five inches in Butler, Saxonburg and Prospect, and four inches in Slippery Rock, with a quarter inch of ice confirmed there.

Palko said the snow fell heavily from about midnight to 2 a.m., and then changed over to freezing rain and ice.

Additional freezing rain was expected this morning. As a precaution, PennDOT temporarily reduced the speed limit on several roads to 45 mph, including Interstate 80 in Clarion and Jefferson counties and Interstate 79 in Butler County.

As of 8:30 a.m., the Butler County 911 dispatch center reported five accidents in Butler County, but no injuries were reported.

Four accidents occurred along Interstate 79 — two in the northwestern part of the county, one in Muddy Creek Township and one in Cranberry Township — and one on Saxonburg Boulevard in Clinton Township, where a vehicle rolled onto its side.There also were numerous reports of vehicles disabled across the county during the morning commute.Temperatures will be dipping into the teens tonight, with some more snow expected overnight into Thursday.The return of very cold temperatures is predicted for Thursday night, when the thermometer may dip to 2 with wind chill readings down to 13 below.Daytime highs will get into the 20s.Another snowstorm is in the forecast for Saturday night going into Sunday. The National Weather Service does not yet have accumulation predictions, but it could be “another significant snow, if things work out,” Palko said.All Butler County school districts canceled classes today, along with Butler County Community College and Slippery Rock University.Also, with many districts now out or almost out of built-in snow days, schools will have to determine when days can be made up. For instance, Butler School District will now be having classes on Feb. 14, which was originally scheduled to be an in-service day for teachers. This makeup day replaces a closure the district had last week.
