PITTSBURGH (KDKA) — Several counties in the Pittsburgh area are under a Winter Storm Warning, including Allegheny, Fayette, Greene, Somerset, Washington and Westmoreland counties.

Other counties in the area are under a Winter Weather Advisory. Those include Armstrong, Beaver, Butler, Indiana and Lawrence.

Both the advisory and storm warning are set to expire at 1 p.m. Saturday.

“After midnight tonight, we’ll start to see the temperature profile change,” he said. “In the upper levels, some milder weather will work its way in and as a result, some mixed precipitation will start to occur for areas Allegheny County on south,” KDKA Chief Meteorologist Jeff Verszyla said.

North of Allegheny County will see just snow from start to finish.

By 8 a.m. Saturday, the mixed precipitation tapered off and by lunch time, the system will be out of the area.

Saturday afternoon will be mostly cloudy.

Overall, Jeff expects counties near Allegheny County to see one-to-four inches of accumulation. Northern counties will get three-to-six inches.
