Temps get hotter in Philadelphia region Thursday as dangerous heat wave continues. Here's the weather forecast.

With a high temperature of 97 degrees Wednesday in the Philadelphia region, our heat wave is now officially our fourth of the year.

Day 3 of a likely seven-day run continues Thursday. The hottest temperatures arrive Thursday and Friday, with temps in the 103 to 105 range. The feels-like temperatures will be 110 to 115 degrees in the Delaware Valley.

In addition, there is a chance for a few pop-up storms, mainly on Friday and Saturday evenings. Some could produce gusty winds and hail, along with lightning and heavy rain.

Saturday is a day that will likely have MANY people outside, especially during the peak heat, because it falls on the Fourth of July with the final 2026 Men's World Cup match at Philadelphia Stadium. It's important to stay hydrated and be mindful of things like headaches, fatigue and dizziness. Those symptoms are all signs that you are entering into heat-related illnesses, and you'll need to cool down immediately.

Heat is the No. 1 weather-related killer, so please take it seriously.

Plan and prepare for the heat

Have somewhere cool to rest, special care for pets, check on neighbors and family, limit time outdoors, check fluid in cars and keep hydrated.

Swimming pools, movie theaters and shopping malls are places to stay cool.

Cars become death traps in the heat. No people or pets should ever be left in the car. The heat can reach 125 degrees in minutes and cause death. Check your back seat before leaving a car.

Buildings with no air conditioning will heat up and retain the heat. That cumulative effect of the heat after 3-5 days could be deadly for some.
