Sunday morning forecast calls for up to 16 inches of snow in Pittsburgh

When it comes to timing this system out, as of 7 a.m., Pittsburgh has seen 3.6" of snow. The highest snow rates, of potentially an inch to two inches an hour, aren't expected until this afternoon. We are certainly tracking on the high side of things when it comes to snow, and we will easily hit our snow range. 

Most should see around a foot of snow falling today, with some areas like the Ridges of Fayette and Westmoreland counties expected to see additional accumulating snow on Monday. We will see isolated totals of snow topping 16 inches.   

It will continue to snow through 10 p.m., with some places continuing to see snow accumulating on Monday.

PennDOT says all roads are snow-covered

PennDOT's Assistant District Executive of Maintenance, Lori Musto, joined KDKA-TV Sunday Morning News to provide an update on the roads and their work. 

Musto told KDKA-TV that the snowstorm is about what they expected. 

"We did expect the snow to stick fairly quickly, and that's exactly what happened," she said. "As soon as it started to snow this morning, we started to see the roads get covered pretty quickly."

While most of the roads are snow-covered, Musto said that as quickly as PennDOT has been able to clear the roads, they're quickly getting recovered once the plow train moves through. 

"We've been trying to run the plow trains on the multi-lane and on the interstates, but as soon as we go through, you're quickly seeing them become snow-covered again," Musto said. 

Of course, Musto stressed that if you don't have to go out, stay home. 

"If you don't have to go out, please don't go out, just give us time to work; but if you do have to go out, give yourself extra time, make sure your vehicle is equipped to handle the snow, obviously, two-wheel drive vehicles or bald tires, people will really have a lot of issues," she said.
