Pittsburgh, Pennsylvania – Thunderstorms rolling through western Pennsylvania Tuesday promise a soggy start to the day, with the risk of heavy rainfall and possible street flooding around Pittsburgh and along I-376. Summer weather alerts are in effect as strong storms develop, putting drivers and residents on notice for fast-changing conditions through the afternoon and evening.
According to the National Weather Service in Pittsburgh, Tuesday’s showers and thunderstorms will begin late morning and last through sunset. The most intense downpours are expected from noon to 6 p.m., especially in Allegheny County and along major routes like I-376, I-79, and the Parkway East. A flood watch remains in place, with rainfall amounts approaching an inch in some neighborhoods. Winds may gust over 30 mph in stronger storms, raising the chance for isolated power outages and downed branches.
Residents are urged to avoid driving through flooded roads and to check updates if commuting after lunchtime. School and work delays aren’t likely, but travel plans may need adjusting if rain bands intensify quickly. Keep cell phones charged and secure loose outdoor items. Emergency crews and spotters may be activated if conditions worsen.
The unsettled weather lingers into Wednesday, with scattered storms and patchy fog overnight. Conditions begin to dry out Thursday, but pop-up storms could return by the weekend. Warm summer temperatures will stick around, with highs staying in the mid to upper 80s through Saturday.
