Metro Detroit weather: Heat index could hit 100 as stretch of 90-degree days begins

Stretch of excessive heat begins

Metro Detroit is under an excessive heat warning as this week's stretch of hot weather moves in. The day starts with rain, but that fades as temperatures move into the 90s.

DETROIT (FOX 2) - The heat will dominate the week, but we're starting off the work week with torrential early morning rain. The wet weather will wind down by mid or late morning with nothing more than an isolated storm late in the day.

Heat advisories and excessive heat warnings are in place, but don't get bogged down by the definitions, just know it will be hot.

Your daily peak heat index will range from 95-100° through the week and possibly into the weekend. Overnight lows hold in the 70s so there isn't much cooling off. This will be a tough stretch for those without AC and for those who work outside. Tuesday and Wednesday will feature an ill defined afternoon storm chance, but it looks like most of Tuesday and Wednesday wind up dry.

The heat sticks through the week and likely through the weekend with afternoon high temps challenging daily records. Cooler weather arrives next week.
