Indianapolis is staring down a sticky midweek scorcher, with the National Weather Service issuing a Heat Advisory for Indianapolis and Marion County from noon to 8 p.m. Wednesday as hot, humid air sends afternoon heat indexes close to 100 degrees. Temperatures will climb into the 90s and relief will be hard to come by during peak heating hours, making outdoor work and other strenuous activity a risky proposition for many residents.
According to the National Weather Service in Indianapolis, the advisory covers portions of central Indiana, including Marion County, and highlights heat index values topping out near 100 degrees in the afternoon. In a bulletin issued late Tuesday, the agency placed several neighboring counties under the same advisory and flagged heat-related illnesses as the main concern to watch.
What To Expect Wednesday Afternoon
The National Weather Service is calling for daytime highs in the 90s, with the humidity pushing the “feels like” temperature close to 100. In parts of northern central Indiana, overnight lows are expected to linger near 70, offering only limited cooling. Forecasters warn that the combination of heat and humidity can make extended time outdoors dangerous and advise keeping strenuous activity to the cooler parts of the day.
City Guidance And Air Quality Concerns
The City of Indianapolis urged residents on Facebook to stay out of the sun during the hottest stretch of the day and to keep hydrated, especially children and older adults; the City of Indianapolis - Government posted the alert Tuesday evening. At the same time, the Indiana Department of Environmental Management’s SmogWatch has flagged an Air Quality Action Day for Wednesday and warns that ozone levels may be unhealthy for sensitive groups, encouraging people to cut back on lengthy outdoor exertion; see IDEM SmogWatch for details.
