Hot, humid weather leads to excessive heat warning in Philadelphia area; storm chances through weekend

Excessive heat warning, other heat alerts in Philadelphia area with sweltering temps expected

PHILADELPHIA (CBS) -- The weather hot streak in the Philadelphia area continues on Friday with even more heat and humidity, as the region enters day three of what could be a four-day heat wave.

We've issued a NEXT Weather Alert Day for Friday due to this heat, which includes an excessive heat warning for areas across Pennsylvania, New Jersey and Delaware. They're shaded in purple on the map below.

Anywhere not under an excessive heat warning in our coverage area is under a heat advisory. Both alerts expire at 8 p.m. Friday.

Temperatures will reach 93 in Philadelphia on Friday, but with a high dew point, it will feel as hot as 105 degrees. The feels-like temperatures will be in the triple digits and if you're going to be outside for any period of time, drink plenty of water, take frequent breaks in a shaded (or ideally, air-conditioned) area. CBS News' HealthWatch explained how you can recognize the signs of heat stroke and heat exhaustion.

Some morning showers were clipping the Poconos but more rain is expected Friday afternoon and into the evening, along with each afternoon of this coming weekend.
