After a brief spell of late-summer heat, a couple of rounds of thunderstorms will roll through Detroit and Lower Michigan followed by some of the coolest weather of the season so far.
The weather story into Wednesday will be building heat and humidity as some of the toasty air from the Central states lunges eastward.

The combination of temperature, sunshine, humidity and other factors will make it feel like the temperature near 100 degrees in the urban areas for a few hours during the afternoon.

High temperatures will challenge daily record levels over Lower Michigan through Wednesday.
One or more rounds of thunderstorms are forecast from as Wednesday afternoon and on into Thursday. Any storm through Thursday morning can be locally strong with blinding downpours and gusty winds. A few areas could be hit with travel delays and sporadic power disruptions.

The storms will not break the heat until Thursday afternoon.
Thursday night and Friday, Canadian air will settle in over the region with much lower temperatures and humidity, as well as a gusty breeze. Some people will feel refreshed, while others may mind the sudden chill.
The pattern Friday into the weekend could yield some of the lowest temperatures of the season so far for the metro area and the region in general. High temperatures will only be in the 60s in many locations.
