HEAT WAVE: Friday hits 90, marking first heat wave of 2017

PHILADELPHIA (WTXF) - Friday now officially marks the end of this year's first official heat wave, as we reached a high temperature of 90 degrees in Philadelphia. This has been the city's earliest heat wave since 2009.

After Wednesday and Thursday's highs approached records in the mid-90s, Friday brought more of the same.

Along with the heat, the humidity is here, and will hang around until winds change from a North Westerly direction that has been bringing in humidity from the Gulf of Mexico.

Friday we are looking at a high of 90, but the cooler air is on the way. A cold from is expected to move through the Midwest Friday, and bring cooler temps to our area by Saturday morning.
