Indiana Weather Alert: Fort Wayne Drivers Warned of Foggy Commutes September 17 as Heat Wave Builds Into Weekend
FORT WAYNE, Ind. — Early morning commuters in northern Indiana should be on alert Wednesday, September 17, as dense fog is expected to reduce visibility across I-69 and local roads before sunrise. Conditions could create dangerous travel scenarios until skies clear mid-morning, according to the National Weather Service in Northern Indiana.
Morning Fog and Travel Safety
The patchy fog will be most impactful between the pre-dawn hours and roughly 8 a.m., when visibility may drop quickly and unexpectedly. Drivers are urged to allow extra travel time, use low-beam headlights, and avoid sudden lane changes on highways and county routes. After the fog lifts, skies will turn clear with a high near 86 degrees, signaling the start of a warm late-week pattern.
Heat Wave Expands Through Friday
By Wednesday night, conditions will remain mostly clear with lows around 57 degrees. On Thursday, sunshine will push highs toward 88 degrees, extending the unseasonably warm streak. Friday is also expected to stay mostly sunny with highs near 88 degrees, maintaining the late-summer heat wave. Calm winds across Allen County will offer little relief as daytime warmth builds.
Weekend Storm Chances
The weather pattern begins to shift Saturday as moisture increases, bringing a 30–40% chance of scattered thunderstorms in the afternoon and evening. While storms are not expected to be widespread, downpours and lightning could disrupt outdoor events and travel. By Sunday, storm chances remain with highs near 81 degrees. These unsettled conditions may linger into early next week, when a front is expected to drop temperatures slightly into the low 80s.
