Pittsburgh, Pa. – Unrelenting summer heat returns to Pennsylvania Thursday, July 24th, bringing hazardous conditions and a flash flood risk that could snarl traffic and impact daily routines across Pittsburgh. With highs nearing 93°F and heat index values climbing into the upper 90s, outdoor plans and evening commutes—especially along busy arteries like Route 28—face significant disruption.
According to the National Weather Service, Thursday afternoon and evening will be the most dangerous, as humidity and soaring temperatures combine to push heat index readings toward 100°. Residents are urged to limit time outside, stay hydrated, and check on vulnerable neighbors. The risk doesn’t stop at heat: locally heavy thunderstorms may spark by Friday and Saturday, triggering localized flash flooding in low-lying neighborhoods and on frequently traveled roads.
Travelers and commuters should be alert for sudden downpours and standing water, especially in areas prone to flooding. Emergency officials recommend postponing non-essential trips during peak storm hours and preparing vehicles with emergency kits, including water and chargers. Power outages remain possible if storms intensify.
This pattern of oppressive heat followed by soaking storms will dominate through the weekend. Saturday brings the highest chance for sustained rain and strong storms, which could extend into early next week. Residents should keep devices charged and heed further advisories, as the forecast remains active.
