Expect the warming trend to continue into this weekend as highs mainly in the 70s today give way to mainly the 80s across the area by Sunday. While some isolated showers and storms are possible in the interior central and west this afternoon, the next batch of rain looks to come Sunday afternoon.
Confidence is increasing in a return to above-normal temperatures and humidity next week. This will bring an increasing risk for heat related impacts to the region. The greatest heat risk will be over Lower Michigan, while areas of the northern and eastern U.P. may be cooler due to cooler air off of the Great Lakes. Periodic showers and thunderstorms can be expected as well.
