The second ground-covering snow of the season could come tonight, though it's not expected to do much more than dust the region.
Lake-effect snow will move through Western Pennsylvania this evening, possibly causing rapid drops in visibility and briefly gusty winds that could affect the Parkway West, I-76 and I-79 into Washington, according to the National Weather Service.
Overnight snow showers and flurries will produce a light accumulation of snow, if anything, weather service meteorologist Brad Rehak said. The temperature will fall to 22 degrees.
Lake-effect snow warnings and advisories are in effect for Crawford and Erie counties and northeastern Ohio. A winter weather advisory is in effect until 7 p.m. for Preston and Tucker counties in West Virginia and Garrett and western Allegany counties in Maryland.
Wednesday in Pittsburgh will be partly sunny, peaking at 36 degrees, Mr. Rehak said.
That first ground-covering snow of the season overnight didn't amount to much, but it was enough to set a record in Pittsburgh.
The National Weather Service reports that 2.4 inches of snow fell in the city , a record daily maximum snowfall for Nov. 12. The previous mark was 1.7 inches set in 1911.
The National Weather Service in Pittsburgh had not posted watches or advisories for counties in southwestern Pennsylvania, but lake-effect snow warnings and advisories were in effect for northeastern Ohio. A winter weather advisory was in effect until 7 p.m. for Preston and Tucker counties in West Virginia and Garrett and western Allegany counties in Maryland.
For the most part, accumulations were between 1 and 3 inches. A few areas crossed by heavier snow bands received more. KDKA-TV reported that as of 6 a.m., Bridgeville reported 2.5 inches. About 3 inches of snow fell in the ridges to the southeast.
In Pittsburgh and nearby suburbs, roads and sidewalks remained mostly wet. Some slick areas were reported.
Several weather-related incidents had been reported early Tuesday:
Downed power lines caused the closure of Greentree Road between Route 50 and Lindsay Road in Scott. The Tarentum Bridge over the Allegheny River had been closed by icy conditions, but has reopened. Westbound Interstate 80 was closed at Exit 120 in Clearfield County because of snowy conditions.
Some school districts, primarily in the Laurel Highlands, were operating on a 2-hour delay.
Pennsylvania motorists are reminded that state law requires their cars and trucks to be cleared of snow before driving.
