Weather Authority: Tuesday set to be hottest day of the year as heatwave moves through region

Some may have considered Labor Day Weekend the unofficial end of summer, but temperatures across the Delaware Valley will be in mid-season form for the next several days. 

On Monday, Philadelphia reached a new record temperature of 96 degrees, exceeding the previous record of 93 degrees set in 2008 and matched in 2015 and 2018. 

FOX 29's Sue Serio says Tuesday is expected to reach another record for hottest day of the year as temperature climb back up to the high 90s.

This will only be the third heat wave to roll through the region this year, and it's expected to last six days.

Humidity will stay a little lower Tuesday as it builds into Wednesday with highs in the 90s that will feel like triple digits. 

The oppressive heat is expected to drag into Thursday and Friday, with highs in the 90s forecasted for both days. A round of scattered storms over the weekend should snap the sweltering heat.

Scattered storms on Friday night will give way to more pop-up storms on Saturday and Sunday that will drag temperatures back into the low 80s.
