Chance of storms Thursday in Philadelphia region with feels-like-temps in triple digits. Here's the forecast.

The heat is on in the Philadelphia region as temperatures climb into the lower 90s, but it will feel more like 100-105 degrees thanks to tropical humidity.

Plan for frequent breaks and plenty of water if you're spending time outdoors.

While much of the day stays dry, scattered thunderstorms will develop during the afternoon and evening.

A few storms could become strong with damaging wind gusts, torrential downpours, and localized flash flooding. Keep an eye on the radar if you have outdoor plans later on Thursday.

The biggest story through the weekend remains the combination of dangerous heat, oppressive humidity and daily storm chances.

Each afternoon and evening will bring the opportunity for scattered showers and thunderstorms, but not everyone will see rain every day.
