A Tornado Watch is in effect for Philadelphia, the surrounding suburbs, the Lehigh Valley and Central and North Jersey until 8 p.m. And a Severe Thunderstorm Watch is in effect until 10 p.m. in Delaware and South Jersey.
The extreme heat played a role in the Watches as temps reach 96 in Philly with a heat index of 101.
There were reports of large hail falling mid afternoon in Allentown, Bethlehem and Upper Makefield Bucks County.
Storms started developing across the northern suburbs around 3 p.m. and slowly moved south over the next few hours.
There could be the potential for these storms to become severe and rotate. Gusty winds and possibly an isolated tornado are possible as the storms move through parts of the area Wednesday afternoon.
If a Severe Thunderstorm or Tornado Warning is issued for your area seek shelter immediately. Do not go outside to look for the storm. Stay away from windows and go to the interior of your home on the lowest level.
