A Winter Storm Warning goes into effect at 1 p.m. for counties south of Allegheny County, and a Winter Weather Advisory is in effect for Allegheny County and others to the north.
National Weather Service issues Winter Storm Warning
Earlier this week, the National Weather Service issued a Winter Storm Warning for parts of the Pittsburgh area along and south of I-70 for today and Sunday due to what they described as "a band of heavier snow."
As of Friday evening, nearly all of the Pittsburgh area is expected to see between two and four inches of snow.
In Pittsburgh, the estimate is 3-5 inches and 5-10 for the ridges.
Snow will be coupled with frigid temperatures
As the snow tapers off around midnight Sunday morning, it will remain scattered, but cold air will follow, leaving the low temperatures in the single digits, and the wind chill below zero as gusts could reach up to 15-20 mph.
Road crews prepare for winter storm
Crews across western Pennsylvania say that they're prepared for the impending snowfall. In Allegheny County, there are two dozen trucks and more than 9,000 tons of salt at the ready.
Even with the preparations, they're asking those who don't need to go out to stay off the roads in order to give them the space to clear them.

PennDOT reduces speed limits for several area roadways
As the snow began to fall on Saturday, PennDOT announced it had reduced speed limits for several major roadways across the Pittsburgh area, including Interstates 70, 79 and 376.
PennDOT is urging drivers to avoid unnecessary travel, but for those who must head out, speeds have been reduced to 45 mph on the following highways:
Allegheny County
- Interstates 79, 376 (Parkways East and West), 279 (Parkway North), and 579
- Route 28
Beaver County
- Interstate 376 (Beaver Valley Expressway)
Lawrence County
- Interstate 376
- Interstate 79
Washington and Westmoreland counties
- Interstate 70
Greene and Washington counties
- Interstate 79
Additional speed restrictions on interstates and expressways may be implemented as the storm progresses.
Although roadways will continue to be treated, PennDOT says its goal is to keep roads passable. Roadways will not be completely free of ice and snow, officials say.
PennDOT will continue to treat roadways throughout the storm until precipitation stops and roads are clear.

KDKA-TV Sunday Evening Forecast
Snow moved in right on schedule, and we are now moving into the part of the event where the heaviest rates are expected.
The steady, widespread snow will slowly taper from northwest to southeast between midnight through 4 a.m. Sunday with lingering flurries and snow showers. Lake-effect snow showers are expected to increase in coverage after sunrise and persist most of Sunday into Monday morning. Most of these will impact the I-80 to Route 422 corridors, but it is likely some of these bands—especially if we get a solid fetch off of Huron as well—will make it into the Pittsburgh metro area, leading to locally higher amounts and reduced visibility.
A lake-effect snow warning is in effect for Mercer and Venango counties to account for this.

KDKA-TV Sunday Morning Forecast
Saturday morning is starting off quietly before widespread, impactful snow moves across the region.
Winter Weather Advisories and Winter Storm Warnings start at 1 p.m. today and go until 1 p.m. Sunday. Areas north of I-80 are under a Winter Weather Advisory until 8 a.m. Monday with lake effect snow showers expected Sunday into early Monday behind the system.
After we deal with the snow on Saturday evening, temperatures will begin to fall with temperatures in the low teens and wind chill into the negatives on Sunday.

Hey Ray: Which generation saw the most snowfall?
Every generation loves to say something like, “back in my day, we got so much more snow!” Or the classic tale of having to “walk uphill both ways to school in the snow!”
Bragging about handling snow isn’t new, but let’s explore it. Which generation in Pittsburgh actually witnessed the most snow?
I combed through National Weather Service records on Pittsburgh snowfalls. Historically, 12 inches or more falls occur about once every 15 years.
