Fort Wayne, IN – A blast of August heat will grip Fort Wayne on Sunday, sending heat index values close to 97 degrees and making outdoor activities potentially uncomfortable. Light winds and clear skies will only add to the swelter as temperatures climb toward 90°F.
According to the National Weather Service, the oppressive heat will hold through Sunday night, with lows barely dipping into the low 70s. A weak south wind will shift southwest by evening, signaling a gradual pattern change. By Monday afternoon, clouds will begin building with a 20% chance of showers and thunderstorms after 2 p.m., offering the first hint of relief.
The real shift arrives Tuesday, when a stronger system brings a 60% chance of rain and the potential for afternoon thunderstorms. Localized downpours could slow travel, especially along I-69 and other major routes during the evening commute. Showers may linger into Wednesday before clearing later in the week.
Residents planning outdoor events should stay hydrated Sunday, limit strenuous activity during peak heat, and keep rain gear handy for Tuesday and Wednesday.
