It might not have mattered much to the many Warren County residents who were shoveling, snowblowing, and recreating on Monday where the snow came from.

For the record, it came from the south… And then from the west.

The foot or so of snow that fell on the county Sunday night was from one system. The additional inches that accumulated Monday into Tuesday was from another.

A total of nine to 11 inches was typical throughout northwestern Pennsylvania Sunday night, according to National Weather Service Meteorologist John Banghoff.

“There’s a storm system that came up from the south overnight last night and brought a wintry mix of precipitation to Pennsylvania,” Banghoff said. “In Warren County it was all snow.”

That system had moved on to the northeast by late Monday morning.

“In its wake, the winds turned around,” Banghoff said. “Lake effect snow showers are expected to continue today, tonight, and into Tuesday.”

He said the county could expect another two to three inches by morning.

“It’s two separate systems, but ultimately, the snow continues,” he said. “It’ll taper off during the day Tuesday.”

The Sunday night event was the more significant one.

“The worst of the road conditions are past us as this point,” he said.

PennDOT was aware of the storm and met it head-on with all hands on deck.

“We were out before the storm even hit,” PennDOT’s Bill Henke said. “We had full call-outs.”

He said many areas of the county received a little more than the nine to 11 inches that was common throughout the region.

The department expected the snow to quit by Monday afternoon, but even as it continued to fall, the preparations and ongoing work had had the desired impact.

“The roads look pretty good,” Henke said.

Crews focused initially on the primary roads in the county, and were plowing secondary roads when they could.

“There are some secondary roads we’re trying to get to,” he said.

Banghoff warned that even when snow isn’t falling, a little wind could result in dangerous driving conditions after a snow event.

“It will be a little bit breezy this afternoon – with gusts of 30 to 35 miles per hour,” Banghoff said Monday. “Considerations for blowing snow… the fluffy snow that fell… you get winds picking up and blowing snow can result in reduced visibility and some slick conditions.”

He said Wednesday should provide a little relief in the weather.

“As we head into the middle of the week, we’ll have a mid-week warm-up,” Banghoff said. “It will push 40 by Wednesday.”

Then, it’s back to winter. “A cold front sweeps through Wednesday night and it will be below zero by Friday morning,” he said.
