PITTSBURGH (KDKA) — Winter weather warnings and advisories remain in effect across the area.

The rain, snow and sleet is making for nightmare travel conditions for people out and about for the Thanksgiving holiday.

“At wakeup, there will be some snow showers moving through parts of the area. Wakeup temperature – 30 degrees, 34 at lunchtime,” said KDKA Chief Meteorologist Jeff Verszyla. “Additional snow showers [Wednesday], mainly during the morning; in the afternoon, temperatures closer to the freezing mark and winds will become a bit brisk by the end of the day.”

KDKA’s Kym Gable Reports:

The Winter Storm Warning will be in effect through 1 p.m. Wednesday for Allegheny, Armstrong, Beaver, Butler, Cambria, Clarion, Crawford, Jefferson, Lawrence, Mercer, Somerset and Venango counties.

Greene, Indiana and Washington counties are under a Winter Weather Advisory through the same timeframe.

“In terms of additional snowfall, one to three inches for areas south, two to four in and around Allegheny County, four to six where it has been and likely will stay snow for the duration of this particular storm system,” said Verszyla.

Meanwhile, the rain was relentless for much of the night, but temperatures in the mid-30 kept that rain from turning into snow or ice.

But road crews know that’s all going to change and they’re geared up for that potential dangerous transition.

Much of the focus will be on interstates and the Turnpike, keeping holiday travelers safe.

“If it does turn back to snow, and there’s a period of freezing rain in there, that’s probably the worst case scenario, said Tim Cook, of PennDOT. “Freezing rain is not something we like dealing with at all.”

“If you do have problems along the roadway, we have call boxes every mile and *11,” added Pa. Turnpike Commission Manager Bob Shaffer. “If you have the cell phone with you, just dial *11 and that calls our com center and they will dispatch the needed equipment.”

In Westmoreland County, some late afternoon accidents kept first responders busy Tuesday.

Emergency officials are worried about ice.

“Our concern is, of course, power lines and roadways,” said Westmoreland County Emergency Management Coordinator Dan Stevens. “PennDOT’s doing the job of pretreating the roads, and we just have to make sure that people just use some caution when they leave in the morning.”
