PITTSBURGH (KDKA) — It’s been a long week of bitterly cold winter weather, but it looks like the worst is yet to come in the form of snow this weekend and another icy blast of air early next week.

A Winter Weather Advisory and Wind Chill Advisory have been issued for much of the region, including Allegheny, Armstrong, Beaver, Butler, Cambria, Clarion, Greene, Indiana, Jefferson, Lawrence, Mercer, Somerset, Venango and Washington counties.

The Winter Weather Advisory is in effect from midnight through 6 p.m. Saturday. The Wind Chill Advisory will go into effect Saturday at 6 p.m. and run through 11 a.m. Sunday.

KDKA’s Jon Burnett says the snow will begin after midnight with cloudy and breezy conditions overnight and a low of 12 degrees. We can expect one to two inches by dawn.

“Our radar satellite composite showing you that snow moving in, clouds already building in through the region and they will continue to lower and thicken, those clouds, and eventually the snow showers that are falling now in Cleveland, all the way back into Cincinnati and northern Kentucky will move into our area along with this Alberta Clipper that’s going to usher in colder air eventually,” said Burnett.

On Saturday, it will be a bit warmer with a high of 27; however, we can also expect two to four inches of snow. The Laurel Highlands will see up to six inches.

“We’ve got this one clipper coming through that’s going to bring snow squalls and kick the winds up. [Saturday’s] going to be very blustery, blowing snow from time to time, be careful if you’re out and about,” said Burnett. “That’s the first front that goes through; the second front is the one that will be packing the real bitter cold, dangerously cold punch and that’ll move in here Sunday night and Monday with another round of accumulating snowfall, and as I said, the coldest air in the last 20 years.”

On Sunday, we’ll see another one to two inches of snow and a high of 25 degrees.

Then, temperatures will plunge again at the beginning and middle of next week with sub-zero lows in the forecast for Tuesday and Wednesday.

“This cold snap that we’re in the midst of, there’s been nothing like it in the last 30 years,” said Burnett. “You’ve got to go all the way back to 1982 to find a stretch of weather that was this cold for this long.”
