Indianapolis drivers should prepare for changing conditions as hot, hazy skies turn stormy by late Sunday and Monday. Thunderstorms could bring downpours, gusty winds, and lightning along major routes like I-65, making commutes difficult. Residents sensitive to poor air quality also face added risks through tonight.
According to the Indiana Department of Environmental Management, an Air Quality Action Day remains in effect until midnight Saturday. Ozone levels are unhealthy for sensitive groups. The National Weather Service in Indianapolis reports scattered thunderstorms developing Sunday morning, growing stronger by afternoon and evening. Showers are expected to continue through Monday night, with rainfall totals up to an inch.
Localized flooding could develop in low-lying areas, and lightning poses a safety hazard for outdoor events. Motorists are urged to limit unnecessary travel during peak storms, slow down on slick pavement, and avoid flooded intersections. Sensitive groups should reduce outdoor activity tonight and consider staying indoors during periods of heavy smoke or haze.
By Tuesday, scattered showers linger but intensity decreases. Midweek brings slightly cooler temperatures with highs in the mid-70s. While severe storms are not anticipated, isolated strong cells with damaging winds remain possible Sunday afternoon.
