WEST MICHIGAN — The last official weekend of summer will feel a lot more like fall across the area. After seeing highs in the mid to upper 70s on Wednesday, afternoon highs will struggle to get into the lower 60s on Friday and Saturday.

The reason for the cooler temperatures is a strong cold front that is basically halfway through the area as of this writing.


A second front north of Lake Superior will "catch up" to the first one tomorrow, providing a powerful shot of colder air to the entire Great Lakes and Midwest regions. Although lows will be centered near 50° on Thursday morning -- with afternoon highs in the mid to upper 60s -- even colder air will settle in behind these fronts on Friday and Saturday mornings. Here is a look at sunrise temperatures on Friday morning according to Future Track:

Although these temperatures may be running a bit cooler than reality, the model information does make a good point... That a serious change in our weather is coming our way. It could be cold enough for frost, in fact, in some areas north and northeast of Grand Rapids Friday, Saturday, and/or Sunday mornings.

This will be the coldest air we've experienced since early June, or even the middle of May, depending on your perspective. Here is a look at forecast lows for Grand Rapids Friday through Sunday mornings compared to some of our coldest morning lows from back in late spring:


This cool snap doesn't mean we don't have any more warm days left. In fact, we expect highs in the upper 70s to possibly near 80° by the middle of next week. Stay tuned to FOX 17 for updates!
