Philadelphia, Pennsylvania – A surge of summer heat and storms will put Philadelphia’s afternoon at risk, with heavy rain and thunderstorms moving in by 1 p.m. Wednesday. Drivers on I-95 and I-76 should brace for wet pavement and sudden visibility drops just as traffic peaks, raising the risk of accidents and delays.
According to the National Weather Service, showers and thunderstorms are likely across Philadelphia starting early Wednesday afternoon, pushing temperatures close to 90°. Rain chances climb to 70% by Thursday, and any storm could bring gusty winds or brief flooding on city roads. Local emergency management urges residents to keep phones charged, avoid flooded intersections, and monitor alerts if venturing out. Public transit delays are possible.
Impacts will hit city neighborhoods and surrounding suburbs, including Montgomery and Delaware counties. By Wednesday night, additional downpours may slow evening commutes and disrupt outdoor plans. Utility crews are on standby for scattered power outages if stronger cells pass through.
Looking ahead, Thursday brings more storms and showers with a high near 85°. Friday and Saturday remain unsettled, with thunderstorm chances and highs in the upper 80s, though some sunshine is expected each day. If you’re planning to attend events or travel this weekend, pack rain gear and watch for updates. Sunday stays muggy, with more afternoon storms likely.
Storm risks linger through the week, so check for advisories before heading out. More updates will be issued if weather conditions change.
