Caution: Heat indices to reach 100-105 degrees in Metro Detroit Wednesday

Metro Detroit under extreme heat warning Wednesday afternoon through Thursday morning

Here is the weather forecast for Metro Detroit.

DETROITGood Wednesday afternoon!

All of Metro Detroit south of M-59 is under an excessive heat warning starting this afternoon due to extreme heat and oppressive humidity. The warning begins at noon and lasts until 8 a.m. on Thursday.

Our highs will likely break a record in Detroit today with 97 degrees as the target, which beats the old June 15 record high of 95 degrees set back in 1988. The humidity will make it feel like 105 degrees, creating concern for heat related illness, especially for anyone who must work outside. Seek shade and take frequent breaks, as the sun will bake all of SE Lower Michigan and Southern Ontario.

Our North Zone is also under a heat advisory, with heat indices expected to reach 100-104 degrees.

Be careful, everyone -- don’t forget your pets, and check on your neighbors.

The heat relief doesn’t arrive until Friday.

Morning lows will be in the mid-60s, and afternoon highs will settle in the low 80s with bountiful sunshine.

Father’s Day weekend will bring beautiful sun and comfy temps with lows in the low 50s and highs around 75 degrees Saturday. Sunday is also Juneteenth, and will be brilliantly bright with highs between 75-80 degrees.

Heat returns next week

We will see a return of the heat and humidity next week with a nice climb Monday into the mid-80s and a slight chance for a few afternoon thundershowers. Tuesday will bring us back into the 90s with a few pop-up showers possible.
