Amid another day of intense heat and humidity Friday, we'll be turning our attention to the skies Friday afternoon and evening with severe storms expected to impact parts of the area. 

What we know:

A region-wide severe thunderstorm watch for the for Friday night calls for wind gusts up to 65 MPH and quarter-sized hail possible. Frequent lightning will also be possible with those storms.

A storm system moving across the western part of the state early Friday afternoon prompted severe thunderstorm warnings in some areas, including Berks, Bucks, Carbon, and Lehigh Monroe, and Northampton counties. 

A flash flood warning was also issued for most of those areas through 8:15 p.m. Friday. 

A heat advisory issued on Thursday by the National Weather Service continued Friday and will remain in effect through the weekend.

After Friday's storms, expect temperatures to fall into the 70s overnight before climbing back into the mid-90s both Saturday and Sunday, and once again on Monday. 

Humidity will make this stretch of heat even more uncomfortable. 

What's next:

The Philadelphia area will officially reach its sixth heat wave of the summer on Saturday. 

Temperatures will stay in the 90s with humidity throughout the weekend and into the early part of next week.
