PITTSBURGH (KDKA) — Snow flurries were flying off and on across the Pittsburgh area Sunday, and at times, it made it difficult for drivers to see.

A Winter Weather Advisory has been issued for Somerset County through 10 a.m. Monday.

Meanwhile, snow squalls have been affecting many parts of the area, including portions of Allegheny, Greene, Fayette, Armstrong, Butler, Indiana, Washington and Westmoreland counties, for much of the day.

Forecasters say the snow squalls are rapidly dropping visibilities to less than a quarter of a mile.

KDKA’s Jon Burnett says temperatures will be very cold on Monday with an expected high of just 33 degrees.

Snow showers are expected to continue this evening, leaving behind a coating to a quarter of an inch to a half an inch on the grassy areas.

“The good news is though, [Monday] we’ll see just a few snow showers, a couple of flurries early; and then things will start to slowly but surely clear out,” said Burnett.

However, the snow will continue to fly through tonight.

“That Lake Effect Snowbelt band plus an upper level low traveling to our south and east is causing these light snow showers, which will begin to let up around midnight, I believe, and then end all together by early [Monday] morning… just a couple of flurries left over then as low pressure drives off the eastern seaboard and the storm track takes it away from us,” he added.

Burnett says it will continue to stay winter-like until mid-week.

“Then, all of sudden, it’s going to seem like we just jumped into late May, a major warm up by the time we get to Wednesday, and Thursday too,” Burnett said. “It’s going to stay balmy around here almost until next weekend, and then it gets cold again.”

Burnett says 21 degrees is expected for the overnight low.

Drivers are being warned to stay alert for icy road surfaces during the morning commute as the snow could fall fast enough to quickly melt and re-freeze.
