Forecast: Stormy end to the week in metro Detroit

Then cooler air settles in

By Paul Gross - Meteorologist

DETROIT - Partly cloudy, warm and muggy tonight, with the slight chance for a thunderstorm. Lows near 70. Southwest wind decreasing to 4 to 8 mph.

Friday will be hot and steamy -- one of the most uncomfortable days we've seen all summer. While a rogue thunderstorm could occur anytime, I think most of the day will be dry until a line of thunderstorms erupts between 4 and 5 p.m., then moves across the area. Strong storms are certainly possible, with damaging wind gusts and torrential rainfall the biggest concerns.

Once again, some flooding is possible in areas that get multiple batches of storms. This could impact Friday evening high school football games, so stay tuned (an even better idea is to download the FREE Local4Casters weather app, which has a great radar display you can zoom in as tight as you want to track storms heading your way)Highs in the upper 80s, but the humidity will make it feel like it's well into the 90s. Southwest wind at 15 to 20 mph.

Showers and storms continue well into Friday evening as a cold front crosses the area. However, not all cold fronts are created equal, and there will still be some rain BEHIND this front that could linger well into the overnight hours. At least the front will shove the heat and humidity eastward, leaving us with lows in the mid 50s north to low 60s far south.

Saturday morning could start with some rain south of Detroit, but any of you who do start with showers should see those end by mid to late morning. Basically, the farther north you are, the better the chance for a dry Saturday. But it'll be much cooler, too, with highs barely making it into the low 70s.

By the way, if you're heading to South Bend for the Michigan – Notre Dame game, it's going to be a perfect night for football, with temperatures dropping through the 60s, with light wind. Not going to South Bend? That's OK, you can watch the game right here on Local 4! Go Blue! If you're heading out to Eugene, Oregon for the Michigan State-Oregon game, the game will start in sunshine with temperatures in the low 90s, but temps should fall into the mid to upper 70s by the end of the game. Go Green!

Mostly clear Saturday night, with lows in the low 50s (it'll be a pretty chilly early tee time Sunday morning if you'll be playing golf).

Mostly sunny on Sunday, with highs in the mid 70s. Looks like a great cider mill day -- let's hope that the yellow jackets take the day off! Mostly clear Sunday night, with lows in the low to mid 50s.

Mostly sunny on Monday, with highs in the mid 70s. Becoming partly cloudy Monday night, with lows in the mid 50s…and your Lions tailgate weather (Monday Night Football edition!) will be perfect, with pre-game temps in the low to mid 70s.

The Tuesday thru Thursday forecast is highly uncertain, as my computer models are developing a series of weak weather systems. You've heard me discuss before that the models are notoriously poor at resolving the evolution of weak weather systems many days in advance, and this is no exception. It looks like a chance of showers all three days, but there will also be dry periods…I don't think we'll completely rain out any day. But I won't be able to get specific about the rain timing for a while. Highs holding generally in the mid 70s.
