South Bend, Indiana – Hot, muggy conditions are taking hold across Indiana, Michigan, and Ohio this holiday weekend, with temperatures expected to feel near 100°F by Saturday and Sunday. A few pop-up storms today could bring heavy rain and brief wind gusts, especially in northern Indiana and southeast Michigan.
According to the National Weather Service, scattered thunderstorms could develop this afternoon and evening across northern Indiana, southeast Michigan, and northeast Illinois. While severe weather is not anticipated, isolated downpours may cause ponding on roads. A more organized storm threat is possible Saturday night into Sunday, bringing increased chances for gusty winds and localized flooding.
Cities like Fort Wayne, Elkhart, Toledo, and Kalamazoo will see afternoon highs in the upper 80s Friday, with humidity pushing heat index values into the mid-90s. By Saturday, real-feel temps between 95–100°F are expected across much of the region, including Chicago, South Bend, and Findlay.
Residents should limit outdoor activity during peak heat, stay hydrated, and check on vulnerable neighbors. Power demand may surge due to widespread air conditioning use.
Thunderstorm chances return Saturday night through early next week, with the next significant update expected Friday morning. Additional watches or warnings may be issued as conditions evolve.
