Fort Wayne, Indiana – Hazy skies and sticky air are already settling across northern Indiana, and the atmosphere is primed for another active day. Heat is building, wildfire smoke continues drifting overhead, and thunderstorms could quickly disrupt outdoor plans before the afternoon is over.
Northern Indiana is dealing with a combination of summer heat, wildfire smoke and developing thunderstorms as temperatures climb toward 90 degrees today. According to the National Weather Service and the Indiana Department of Environmental Management (IDEM), an Air Quality Alert remains in effect through Monday, with elevated fine-particle pollution from Canadian wildfire smoke affecting much of the region.
The weather becomes increasingly unsettled as the day progresses. Showers and thunderstorms are expected with an 80 percent chance of rain, while heat index values may reach 102 degrees. Southwest winds could gust to 25 mph, and stronger thunderstorms may produce torrential rainfall, frequent lightning and brief reductions in visibility for drivers along Interstate 69, U.S. 24 and Interstate 469.
Residents with asthma, heart disease or other respiratory conditions should reduce prolonged outdoor activity, especially during the warmest part of the day. Keep windows closed when possible and use air conditioning or high-efficiency filtration if available. Anyone spending time outdoors should stay hydrated, take frequent breaks and monitor the sky for rapidly developing storms.
The weather settles somewhat on Sunday with highs in the lower 80s, although patchy wildfire smoke may linger. Monday turns warmer again near 85 degrees before another round of showers and thunderstorms develops Monday night. Additional showers remain possible Tuesday as the active weather pattern continues across the Great Lakes and Ohio Valley.
The broader 6-to-10-day outlook favors above-normal temperatures across the Midwest late next week, suggesting the midsummer warmth is likely to continue.
