Southern Indiana endures early season heatwave, dangerous heat index values expected

INDIANA – Southern Indiana is currently experiencing an unseasonable and persistent heatwave, with high temperatures anticipated to remain around 95 degrees Fahrenheit through Friday. This prolonged period of elevated temperatures is considered unusual for so early in the season and carries significant health risks.

Overnight lows are predicted to stay in the mid-70s, offering minimal relief from the daytime heat. Of particular concern are the expected heat index values, which are forecasted to reach a dangerous range of 100 to 107 degrees.

While there is a slight chance of afternoon thunderstorms each day, these are expected to provide only minimal respite from the oppressive conditions. Forecasters are closely monitoring the system.

A minor cooldown is projected for the upcoming weekend, with highs dipping into the lower 90s. However, significant relief from the heat may not arrive until early next week. Current models suggest that a cool front moving into the Great Lakes region could bring more comfortable temperatures and increased chances of rain next Monday or Tuesday.
