Pittsburgh, Pennsylvania – Storms will surge into western Pennsylvania by early Thursday afternoon, bringing heavy rain, lightning, and dangerous heat just in time for the evening commute.
According to the National Weather Service, showers and thunderstorms will likely develop after 1 p.m. Thursday across Allegheny County, with highs near 90°F and heat index values close to 100°F. Calm winds and moisture-heavy air will make for a muggy, unstable day — the perfect setup for strong downpours and possible flash flooding. Rain chances sit at 50% Thursday, rising to 60% by nightfall.
Pittsburgh drivers, especially along Route 376 and I-79, should plan for slick roads, reduced visibility, and potential delays during the afternoon rush. Localized flooding is possible in low-lying or poorly drained areas. With much of the region under an Extreme Heat Warning until 5 p.m. Wednesday, lingering high humidity will continue to pose heat risks through the weekend.
Friday brings more storm activity with a 70% chance of rain and scattered thunderstorms throughout the day. Highs will hold in the low 90s through Saturday, with steamy conditions and occasional pop-up storms continuing. Relief is expected early next week as temperatures dip slightly, but wet conditions remain likely.
Avoid non-essential travel during storms, secure loose outdoor items, and check local alerts before heading out.
⚠️ Stay tuned for updates if new watches or warnings are issued.
