Central WI back in the 90s. Are these high temps normal & will it last?

Central Wisconsin is experiencing a significant heat wave, with temperatures expected to remain in the 90s throughout the week. According to the National Weather Service, high humidity will push heat indices between 95 and 105 degrees.
