After a week of weather suited for meteorological autumn, the Philadelphia area can expect a steamy two-day return of summer starting Wednesday, with temperatures pushing 90 degrees and dew points making it feel hotter.

And as with most hot and humid summer days, there will be a chance of showers and thunderstorms Wednesday night into Thursday, which looks to be a repeat of the day before.

According to the National Weather Service, the projected high in Philadelphia on Wednesday is 89 degrees, with heat indexes in the mid-90s.

On Thursday, the projected high is 87, with heat indexes around 93 degrees.
