PITTSBURGH, Pa. – Commuters across western Pennsylvania will need to slow down Thursday morning as patchy fog lingers on major roadways, including I-376, before skies clear into a sunny October afternoon. Expect reduced visibility during early drives, making caution essential for school buses and rush-hour traffic.
According to the National Weather Service in Pittsburgh, Thursday will turn mostly sunny with a high near 75 degrees. Fog remains a concern before 8 a.m., especially in low-lying valleys and along river corridors. Winds from the northeast at 7 to 9 mph will help clear conditions by late morning.
Cooler nights remain the pattern through the weekend, with temperatures dipping into the 40s across Allegheny County. That means brisk evenings for outdoor events and chilly mornings for early commuters. Friday brings a high near 77 with more sunshine, while Saturday warms slightly to around 80 before patchy fog returns overnight.
The mix of warm afternoons and crisp mornings signals a classic fall setup for Pittsburgh. Residents should prepare for changing conditions, dressing in layers and allowing extra time for morning travel through fog-prone corridors. The region’s dry stretch also gives crews a chance to complete road projects without interruption, a boost for drivers navigating construction zones.
Looking ahead, sunshine dominates much of early October, giving western Pennsylvania a welcome stretch of calm weather. Still, officials remind drivers that sudden fog can reduce visibility within minutes, and headlights should always be used during low-visibility conditions.
