Northern Indiana will experience a hot and humid Sunday, followed by the likelihood of severe thunderstorms on Monday afternoon and evening. These storms could bring heavy rain, gusty winds, and lightning, especially along key highways like U.S. 30 and the I-69 corridor.
Areas Affected by Heat and Storms
The National Weather Service in Northern Indiana reports that Sunday will be hot and humid, with temperatures climbing into the upper 80s to low 90s. There is a low chance (15–20%) of pop-up storms, but most of the day will remain dry. However, the real concern starts on Monday, when the weather becomes more volatile.
Monday Storm Risk: A 70–90% chance of thunderstorms will develop late in the afternoon and continue into the evening. These storms may bring heavy rain, gusty winds, and frequent lightning, particularly in areas like South Bend, Warsaw, and Fort Wayne.
Commute Disruptions: The timing of these storms could disrupt the Monday evening commute, with reduced visibility and possible delays. Travelers on major roads like U.S. 30 and I-69 should be prepared for challenging conditions.
