Pennsylvania – Light flakes drift across rooftops this morning as gray skies settle over western Pennsylvania. Cold air already grips the region, and snow chances increase fast, setting up a wintry stretch that could impact travel through the holiday weekend.
According to the National Weather Service in Pittsburgh, snow develops later today and becomes more widespread tonight. Accumulations remain light, generally under an inch, but road conditions may deteriorate quickly after sunset as temperatures slide toward the low 30s.
Saturday brings steadier snow, especially during the morning and early afternoon. Highs hover near 39, warm enough for wet roads at times. That window closes quickly after dark. As colder air pours in Saturday night, slush may freeze solid, creating slick conditions on bridges, hills, and untreated side streets.
Sunday turns sharply colder. Highs struggle to reach the mid-20s, and any lingering snow showers taper off. Gusty winds add bite, dropping wind chills into the teens. Drivers should watch for black ice, especially during early morning and evening hours.
By MLK Day, winter tightens its grip. Another round of snow is possible Monday afternoon, followed by a deep freeze Monday night. Lows plunge near 5 degrees, cold enough to refreeze melted snow and stress vehicles, pipes, and exposed infrastructure.
Tuesday stays frigid despite some sun. Highs remain near 18, well below average. Travel impacts ease, but prolonged cold keeps winter hazards in place.
Meteorologists continue tracking an active pattern next week, with additional snow chances returning by midweek as cold air stays locked across the region.
