PITTSBURGH (KDKA) — Snow showers have moved into the area, and a blast of frigid air is right behind it.

Snow arrived Thursday morning, and is expected to get heavier as the day goes on.

“We’ll see a light snow continuing through the afternoon,” Verszyla said. “Our high temperatures of 30 degrees will be reached right around mid-day, then we’ll start to push some colder air into the mix. Temperatures will start to drop a bit in the afternoon, down to 25 later in the day, so it’s colder the second half of the afternoon.”

A Winter Weather Advisory has been issued for Allegheny, Armstrong, Beaver, Butler, Cambria, Clarion, Greene, Indiana, Jefferson, Lawrence, Mercer, Somerset, Venango and Washington counties from 7 a.m. to midnight.

For snowfall totals, we’ll list a 12-hour range – 9 o’clock [Thursday] morning through 9 o’clock [Thursday] evening. Again, it’s going to be a light snow, but it’s more of a duration event – a light snow over an extended period of time that will give us two to four inches of total snowfall,” Verszyla said. “Three to five as you get closer to the I-80 corridor, and a little less for areas to the south.”

A Wind Chill Advisory is also in effect for those same areas from 7 p.m. Thursday to noon Friday.

“We’ll see an area of low pressure rapidly moving through the area [Thursday] into [Thursday] evening,” Verszyla said. “As the low passes by to the south and begins to head toward the coast, the energy and the moisture is going to go along with it, so our snow is going to rapidly come to an end [Thursday] evening, should be an abrupt end sometime the middle part of [Thursday] evening, and then we’ll start to push in that colder air [Thursday] night and into the day on Friday. The initial push will come with some gusty winds as well, so wind chill advisory for [Thursday] night into Friday morning.”

On Friday, Verszyla says there will be a lingering morning flurry, but with high pressure building in skies are expected to brighten, and the core of the coldest air will be in place. Temperatures are expected to be in the teens all day.
