PENNSYLVANIA – Summer heat will hang on for one more day before Pittsburgh braces for a round of fall storms Sunday night. Travelers and residents should stay alert as strong showers and thunderstorms could make evening commutes and outdoor plans difficult across Allegheny County.
According to the National Weather Service, skies stay mostly sunny Saturday with highs near 86, but clouds build by evening. A chance of showers arrives late Sunday, with thunder possible after dark. Rain chances increase through Monday, raising concerns for slick roads, especially along major routes such as Parkway East (I-376).
Localized downpours may reduce visibility, and strong storms could bring heavy rain totals in a short window. Drivers should slow down on wet pavement, and anyone with outdoor weekend events should plan for quick weather changes after sunset Sunday.
Monday carries the highest risk, with widespread rain likely and highs in the low 80s. By Tuesday, thunderstorms may linger, keeping morning commutes slow and afternoon outdoor activities unsettled. Emergency managers remind residents to secure loose outdoor items and charge devices ahead of potential power outages.
Conditions improve midweek, with scattered showers tapering off by Wednesday and partly sunny skies returning Thursday as temperatures settle into the 70s.
Warnings remain possible if storm systems strengthen, with updates expected throughout the weekend.
