A heat advisory issued for the parts of the area remained in effect until 8 p.m. Friday.
The advisory, declared by the National Weather Service included Philadelphia, Camden, Trenton, Wilmington and several adjacent counties including Delaware, Chester, Bucks, Montgomery, Gloucester, Mercer, Camden, and New Castle.
Temperatures could climb to the record high of 95 degrees, NBC10 First Alert Weather Chief Meteorologist Glenn "Hurricane" Schwartz said. Humidity will continue to build through the day and push the heat index — how warm it actually feels — toward the century mark.
The high heat and humidity combo can prove dangerous for anyone doing prolonged work outdoors and those with breathing issues. Philadelphia health officials are reminding citizens to drink plenty of water and not overexert themselves Friday.

The National Weather Service also issued an air quality alert level orange for parts of Chester, Montgomery, Bucks, Delaware and Philadelphia Counties.
A code orange air quality alert means that air pollution concentrations within the region may become unhealthy for sensitive groups such as the elderly and children.
People are reminded to open their windows if they do not have air conditioning as homes can quickly become like ovens in the heat.
Health officials also remind drivers not to leave the most susceptible populations — the elderly, children and pets — in cars in the excessive heat.
