"The heat peaks on Wednesday over the area as temperatures should get well into the 90s with increasing humidity," the National Weather Service said.

The front moving in from the Midwest where it already has set records.

Dense areas most impacted by the urban heat island effect, including Philadelphia and parts of Montgomery and Delaware counties, will be under an extreme heat watch all day Wednesday. The watch indicates life-threatening conditions are possible with 72 hours.

A heat advisory, meanwhile, is in place for the rest of the region from Tuesday afternoon and into Wednesday evening.

"Heat related illnesses increase significantly during
extreme heat and high humidity events," the National Weather Service added.

Highs are not forecasted to drop out of the 90s until Sunday.

"A dry cold front looks to pass sometime late Wednesday which will knock down temperatures a bit, but medium range guidance and ensembles indicate above normal temperatures in the upper-80s/low-90s could remain through the end of the week and potentially into the weekend," the National Weather Service said.

By late week and into the weekend, there is another possibility of showers and thunderstorms, with some being severe, forecasters said.
