The weather we feel here at the ground follows from what happens aloft. The weather pattern aloft is going to look like fall late this week.
A very fall-like situation of a storm center just northeast of Michigan is going to develop at the end of the week. Our surface temperatures will then cool to early September normals.
Here’s what the upper-air flow is going to look like this Thursday.

The forecast graphic above basically shows you the flow of the upper-air. Take a black line over Michigan and follow it back to the left of the image. You’ll see our flow will be coming out of the northwest. Our air will be coming from central Canada on Thursday.

Thursday is going to be in the mid-to-upper 70s across the southern half of Lower Michigan. That will be a real fall feel.
Friday's forecast high temperatures. (weathermodels.com)
Friday could have temperatures a couple of degrees cooler than Thursday. Two days in a row feeling like fall will make you look at the calendar.
Let’s also add in a brisk northwest wind.
Thursday wind forecast shows a northwest wind at 10 mph to 20 mph will blow across the entire state. (weathermodels.com)
Some puffy, cottony fair-weather clouds, a brisk northwest wind and temperatures only in the 70s will make a fall feel here in Michigan.
There will be some days in the 80s after our taste of fall. But the middle to end of next week looks to have another cool-down into the 70s and 60s for afternoon temperatures.
We still have a month of summer-like weather, but several day stretches of fall spurts are going to be common in the next three weeks.
