Harrisburg, Pennsylvania – A colder, snow-favored weather pattern is becoming more likely across Pennsylvania late next week, with the potential for multiple snow events increasing between Jan 20 and Jan 26. While exact storm timing remains uncertain, the broader setup now points toward snow being more likely than rain across much of the Commonwealth.
According to the National Weather Service and the Climate Prediction Center, Pennsylvania is highlighted for a 40 percent chance of above-normal precipitation during the 8–14 day period. At the same time, temperature trends support colder air holding across the region, increasing the likelihood that precipitation falls primarily as snow, especially across western, central, and northern parts of the state.
Western Pennsylvania, including Pittsburgh, Beaver County, and areas north toward Butler and Clarion, could see repeated rounds of light to moderate snow as systems track through the Ohio Valley. Snow potential increases overnight and during early morning hours when colder air is most established.
Central Pennsylvania, including State College, Altoona, and Johnstown, appears particularly favored for accumulating snow. Higher elevations along the Allegheny Front and Laurel Highlands could see steadier snowfall, with colder air allowing snow to persist even during daytime periods at times.
Farther east, including Harrisburg, the Susquehanna Valley, and parts of eastern Pennsylvania, snow remains possible, especially during colder windows. While brief mixing cannot be ruled out closer to Philadelphia, snow potential appears higher than rain for much of the interior.
Drivers should prepare for slick roads along major corridors including I-76, I-80, and I-81, especially during morning and evening commutes. Multiple snow events over several days could compound travel impacts.
Residents are encouraged to review winter preparedness plans and monitor updated outlooks. Confidence will continue to improve as the window approaches, and additional winter weather advisories may be issued if the snow signal strengthens further.
