The region's ridge areas can expect more snow today, reports the National Weather Service at Pittsburgh.
A winter weather advisory remains in effect through 7 p.m. for the higher elevations of Westmoreland and Fayette counties, said John Darnley, a meteorologist with the weather service. The advisory posted for Pittsburgh has been lifted.
As of this morning, about 4 inches of snow had fallen in the higher elevations, with a total of 6 to 10 inches expected to accumulate by evening.
"There's going to be some intense snow this afternoon," Mr. Darnley forecast.
As for the Pittsburgh region, Mr. Darnley said he's expecting an additional inch of accumulation by Monday morning. About 3 inches had fallen between Saturday morning and this morning, as measured at the weather service office in Moon.
He said normal winter temperatures will be in effect today. "We'll have a low today of 22 degrees and we're not expecting that to rise much. The high today will be around 24 with an overnight low to Monday morning of about 10 to 11 degrees. It's pretty typical," he said.
The weather service doesn't expect the mercury to rise above freezing until Thursday afternoon when a high of 35 degrees is anticipated.
