PITTSBURGH, Pa. – Commuters across western Pennsylvania should prepare for patchy fog Tuesday morning, especially along I-376 and surrounding valleys, before sunshine brings a warmer afternoon. Drivers are urged to slow down, keep headlights on low beam, and allow extra travel time during the morning commute.
According to the National Weather Service in Pittsburgh, fog could linger until 9 a.m. Tuesday before skies clear. Sunshine will lift highs near 78 degrees, with light east winds shifting to the southeast in the afternoon. The calm stretch of weather builds through midweek, with temperatures climbing into the lower 80s by Thursday.
Pittsburgh International Airport, downtown, and river valleys could see the thickest fog early Tuesday. Rural routes in Allegheny, Beaver, and Washington counties may also be impacted. The Pennsylvania Department of Transportation advises caution in low-visibility conditions, especially near bridges and interchanges.
By Wednesday, skies remain clear with highs reaching 80 degrees. Thursday begins with morning fog again, but afternoon highs climb to 82 degrees, holding steady through Saturday. While evenings stay cool in the 50s, daytime warmth will feel more like late summer than early fall.
Residents are encouraged to enjoy the warm spell but remain alert for foggy mornings. Those with early commutes should allow extra time, and parents should remind teens driving to school to adjust speeds.
Sunny skies and summerlike warmth persist into the weekend, with no rain expected through Sunday. Additional weather updates will be issued if fog becomes dense enough for advisories.
