Pittsburgh, Pennsylvania – A potentially disruptive winter storm could impact much of Pennsylvania from Wednesday, Jan. 14, through Friday, Jan. 17, with the highest confidence for significant snow and travel disruptions focused across the state’s southwestern and south-central regions.
According to the National Weather Service Weather Prediction Center, Pennsylvania currently carries a 20 to 60 percent probability for impactful winter weather, with the greatest likelihood concentrated along the Pennsylvania–West Virginia–Maryland border. This includes portions of southwestern Pennsylvania and the Laurel Highlands, where colder air and favorable storm dynamics may support heavier snowfall.
The most concerning travel impacts are expected along Interstate 79, Interstate 68, and Interstate 81, as well as portions of the Pennsylvania Turnpike, where snow-covered roads and reduced visibility could develop during the heart of the storm. Areas near Pittsburgh, Johnstown, Somerset, and Chambersburg may see prolonged periods of snow, especially during overnight and early morning hours.
Central and eastern Pennsylvania, including Harrisburg, State College, and the Lehigh Valley, remain within a moderate-impact zone. While snowfall totals there are less certain, forecasters warn that small shifts in storm track could bring heavier snow farther east, increasing impacts along I-76, I-83, and Route 22.
Gusty winds may accompany the storm, leading to blowing snow in open and elevated areas, particularly along ridge tops and rural highways. Even modest accumulations could cause significant disruptions due to timing and temperature trends.
Residents are urged to prepare now by reviewing winter travel plans, monitoring PennDOT updates, and ensuring vehicles are equipped for winter conditions. Forecast confidence is expected to increase as the storm approaches, and winter weather advisories or warnings are likely to be issued, especially for southwestern Pennsylvania.
