Pittsburgh, Pennsylvania – Drivers across western Pennsylvania and northern West Virginia could face rapidly deteriorating road conditions Wednesday evening as a stronger round of snow moves in, bringing the heaviest accumulations overnight into early Thursday.
According to the National Weather Service office in Pittsburgh, snow will increase Wednesday afternoon, with the most intense rates expected Wednesday night. A Winter Weather Advisory takes effect for areas east of Interstate 77, where 3 to 6 inches of snow are possible, while a Winter Storm Warning covers the higher terrain of southwestern Pennsylvania and northern West Virginia, where totals could reach 4 to 8 inches.
The highest confidence for impactful snowfall is along the ridges, including parts of Fayette, Westmoreland, Somerset, Preston, and Tucker counties. Snow bands or brief squalls could push localized totals higher and sharply reduce visibility. Pittsburgh and surrounding communities, including Butler, Indiana, and Latrobe, may see several inches with slick secondary roads developing quickly after sunset.
PennDOT and local emergency managers urge motorists to avoid non-essential travel Wednesday night, especially on ridge routes and untreated roads. Residents should allow extra time for the Thursday morning commute, charge mobile devices, and prepare for changing conditions.
Snow tapers off from west to east early Thursday, but lingering slick spots are likely. Additional advisories could be adjusted as snow bands evolve, with warnings remaining in effect through Thursday morning.
