After a brief spell of late-summer heat, a couple of rounds of thunderstorms rolled through Detroit and lower Michigan followed by some of the coolest weather of the season so far.
A change is on the way after building heat and humidity Wednesday challenged daily record levels over lower Michigan.
On Wednesday, the city's high temperature hit 91 degrees during the midday hours.

Rounds of thunderstorms are forecast into Wednesday night. Any storm can be locally strong with blinding downpours and gusty winds. A few areas could be hit with travel delays and sporadic power disruptions.

The heat will not break until Thursday.
Thursday afternoon through Friday, Canadian air will settle in over the region with much lower temperatures and humidity, as well as a gusty breeze.
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.
