Just because the snow hasn't started yet, don't put the shovel and salt away.
The storm expected to hit southwestern Pennsylvania will begin later -- around 10 p.m. to midnight -- and leave behind less snow than was forecast earlier today, according to the National Weather Service.
Southwestern Pennsylvania should expect 1 to 3 inches of snow overnight, weather service meteorologist Brad Rehak said, with an additional 1 to 2 inches settling in for the morning commute.
This storm will draw "a sharp line" through the region, Mr. Rehak said. Northern areas should expect significantly less snow than southern areas.
"That line will be drawn very close to Allegheny County," he said.
A winter weather warning is still in effect for Pittsburgh and areas south: Parts of Washington, Greene and Westmoreland counties could see 4 to 8 inches of snow and higher elevations in Fayette and Westmoreland counties could see up to 9 or 10 inches.
Though the precipitation will likely begin as rain, it will quickly change to snow, Mr. Rehak said.
The snow will be unlike the light, fluffy stuff from over the weekend, weather service meteorologist Tom Green said.
"We are expecting that this will be a kind of heavier, wetter snow, considering our temperatures will be right around freezing," he said.
A winter weather advisory in Beaver, Butler, Armstong and Indiana counties could bring between 3 and 5 inches of snow.
In the calm before the storm, PennDOT crews checked equipment for mechanical problems, ensured materials are stocked and mounted plows on its 70-plus trucks in Allegheny County.
PennDOT, which is responsible for interstates and main arteries like Routes 8, 22 and 28, will be "full force" overnight clearing roads before the morning rush, spokesman James Struzzi said. PennDOT will concentrate on those thoroughfares, then attend to secondary roads.
On Monday, Mr. Rehak called this "probably the last big snow" of the winter.
As of tonight, northern Illinois and Indiana had been hit hardest by this storm, accumulating about 4 to 6 inches of snow, he said.
