Philadelphia, Pennsylvania –Scattered thunderstorms and near-90°F heat will make Sunday feel like peak summer across Philadelphia as a new round of active weather develops.
According to the National Weather Service, Sunday, June 29, will be mostly sunny during the day with highs around 89°F, but a 40% chance of late-day thunderstorms returns by Sunday night. Humidity will surge, making conditions feel more oppressive — especially for anyone planning outdoor activities or travel near I-76 or across the Schuylkill Expressway.
The pattern continues Monday with scattered showers and storms likely again in the afternoon and evening. While no widespread flooding is expected, any isolated downpours could reduce visibility and make for slick roads. Winds remain light, but localized gusts are possible during storms.
Tuesday brings another round of unsettled summer weather, especially after 2 p.m., with an 80% chance of thunderstorms that could linger into the overnight hours. Conditions ease slightly by Wednesday, which looks mostly dry ahead of warmer, drier weather for the holiday.
