Pennsylvania – Damp streets and thickening clouds are already signaling a messy turn as showers build toward Philadelphia, with thunderstorms likely to intensify just in time for the evening commute.
According to the National Weather Service, rain chances rise from 30 percent early to nearly 60 percent by afternoon, with thunderstorms possible after 5 p.m. Rainfall could reach a quarter inch, with localized higher totals under heavier cells. Southwest winds near 10 mph may gust up to 20 mph, briefly reducing visibility on major corridors.
This system stretches across the Mid-Atlantic and Ohio Valley, where a broader spring storm pattern is fueling strong storms and heavy rain. While severe weather remains limited locally, brief downpours and lightning could still disrupt travel across southeastern Pennsylvania and nearby New Jersey.
In Philadelphia, drivers should expect slower conditions along I-95, I-76, and the Schuylkill Expressway during peak travel hours. Wet pavement and sudden visibility drops will make for tricky driving. Plan extra time, keep headlights on, and avoid quick lane changes during heavier rain bursts.
Showers continue into tonight with an 80 percent chance of rain and a low near 50. By Thursday, cooler air settles in with lingering showers before skies improve Friday. A warm-up follows into the weekend, with highs pushing into the low 80s by Saturday, offering a brief taste of summer.
Cloud cover may also affect visibility of the Artemis II launch this evening, though breaks could offer a quick glimpse if skies cooperate.
