South Bend, Indiana – Hotter-than-normal temperatures are set to take hold across northern Indiana, with afternoon highs edging closer to 80 degrees this weekend and heat continuing to build into next week. According to the National Weather Service in Northern Indiana, the Climate Prediction Center now favors above-normal temperatures across the region from late this week through early next week, with South Bend and Fort Wayne both trending several degrees above their usual August averages.
The warming trend will be especially noticeable by Tuesday and Wednesday, when a 20% chance of isolated afternoon thunderstorms develops. Although rainfall chances remain low, there’s also a slight lean toward above-normal precipitation—so residents should watch for brief, pop-up storms, especially in the afternoons. Key roads and neighborhoods in South Bend, Fort Wayne, and surrounding communities could see wet pavement and minor travel disruptions, but widespread severe weather is not expected.
With temperatures reaching the low-to-mid 80s much of next week, Hoosiers are encouraged to stay hydrated, limit strenuous outdoor activity during peak afternoon heat, and make sure pets and vulnerable neighbors have access to cooling options. Weather alerts will be updated if confidence in thunderstorm development increases.
