Pittsburgh, Pennsylvania – Snow will begin coating roads across western Pennsylvania and northern West Virginia by late Tuesday night, setting up slick conditions for the Wednesday morning commute.
According to the National Weather Service in Pittsburgh, a Winter Weather Advisory is in effect from 9 p.m. Tuesday until 1 p.m. Wednesday for Venango, Forest, Clarion and Jefferson counties, along with the higher elevations of Westmoreland, Fayette and Indiana counties in Pennsylvania, and eastern Preston and Tucker counties in West Virginia. Snow totals are expected to range from 2 to 5 inches, with the highest amounts across ridge tops and elevated terrain such as Canaan Valley, Ligonier and Ohiopyle.
Snow will overspread the region after 9 p.m., becoming steady overnight. Gusts up to 35 mph could blow snow across exposed roadways, briefly lowering visibility on routes including U.S. 219, Route 422 and Interstate 80. Some mixing with rain is possible by late Wednesday morning, especially in lower elevations, which may create slushy conditions.
PennDOT and WVDOH crews are expected to treat major highways, but untreated secondary roads could remain snow covered through midday. Drivers should reduce speed, increase following distance and allow extra travel time.
Snow will taper from west to east by early Wednesday afternoon, though additional advisories could follow if colder air lingers behind the system.
