Image 1 of 2

An excessive heat warning is in effect Friday and Saturday for all of metro Detroit. The high temps are causing concern about power supplies and safety.

An excessive heat warning means the hot and humid air will create dangerous conditions, particularly for the elderly and those with pre-existing health conditions. Heat illnesses are likely.

The heat index Friday and Saturday is going to reach into the 100s. Friday's feel-like temperature will be between 101-105, with Saturday surging up to 105-111 degrees. 

Friday the real temperature will top out in the mid 90s, and overnight we won't get much relief. Temps are only expected to drop into the high 70s. Then on Saturday we'll top out again around 96 degrees. 

We'll see multiple chances for rain and storms, too, which is why things are going to feel so humid and steamy. You can keep an eye on the radar, and get any real-time weather alerts with your Fox 2 Weather app.

The heat will finally break on Sunday, where we'll get back down into the 80s. The excessive heat warning expires Saturday at 8 p.m.
