Residents across central Indiana should prepare for dangerous heat and the potential for strong thunderstorms through Thursday, according to the National Weather Service.
A Hazardous Weather Outlook issued Wednesday afternoon warns that scattered showers and thunderstorms are possible through tonight, bringing the threat of strong wind gusts, localized flooding and frequent cloud-to-ground lightning.
The outlook includes the first 10 counties listed in the advisory area: Carroll, Warren, Tippecanoe, Clinton, Howard, Fountain, Montgomery, Boone, Tipton and Hamilton counties.
Temperatures are expected to climb into the lower 90s on Wednesday, with heat index values ranging from 100 to 105 degrees. The combination of heat and humidity may create hazardous conditions for those spending extended periods outdoors.
The hot weather is expected to continue Thursday, with afternoon highs again reaching the lower 90s and heat index values between 95 and 105 degrees.
Forecasters are also monitoring the potential for stronger storms Thursday evening and Thursday night. Some thunderstorms could become severe, with damaging winds identified as the primary threat.
Looking ahead, additional chances for showers and thunderstorms are expected Sunday through Tuesday. While it remains too early to determine the severity of those storms, residents are encouraged to stay informed as forecasts are updated throughout the week.
Officials recommend limiting strenuous outdoor activities during the hottest part of the day, staying hydrated, and seeking shelter immediately if thunderstorms approach.
