PITTSBURGH (KDKA/AP) — Forecasters were calling for less snow than first anticipated as a winter storm moved into Pennsylvania.

In general, the National Weather Service was calling for six to eight inches of snow across the southern quarter of the state, and lesser amounts farther north. Areas along the New York border were expected to receive one to two inches through Monday.

In Pittsburgh, snow began falling about dawn Sunday and was expected to taper off before another band of snow early Monday. Forecasters there were expecting three to six inches total.

A Winter Storm Warning has been issued for several counties including, Allegheny, Fayette, Greene, Somerset, Washington and Westmoreland through 1 p.m. Monday.

Several other counties remain under a Winter Weather Advisory. Those places include Armstrong, Beaver, Butler, Cambria, Clarion, Indiana, Jefferson, Mercer, and Venango counties.

According to PennDOT, the HOV lanes will be closed until further notice because of weather.

“This looks to be the biggest event of the season, which isn’t saying a whole lot; we’ve only had a couple of events as much as four or five inches so far, but we’re going to top that this time,” said KDKA’s Jon Burnett.

The heaviest snow is expected to fall from 6 p.m. Sunday through 8 a.m. Monday.

“It looks like between Interstate 70 to the south and [Interstate] 80 to the north, we’re looking at three to six inches,” Burnett said. “I-70 south, there we’re talking about six to 12 inches, and that would include, Greene County, Fayette County, southern Somerset County, Garrett County, Md., Monongalia County, Morgantown in West Virginia, along with Preston and Tucker counties, too.”

Areas north of I-80 are no longer under a Winter Storm Watch.

“Now, when you get north of I-80, you’re only talking one to three inches, and that’s through noon on Monday,” said Burnett. “And things by noon on Monday will be wrapping up.”

The snow and cold temperatures are expected to make travel treacherous over the next few days. Officials are asking drivers to take it slow and be cautious.
