Louisville, Kentucky – Heat index values in Louisville could reach 105° Monday afternoon, as Kentucky braces for more dangerous summer conditions and the return of scattered storms. A Heat Advisory remains in effect through 8 p.m. Wednesday, keeping much of southern Indiana and central Kentucky under sweltering temperatures and intermittent thunderstorm threats.
According to the National Weather Service in Louisville, heat index values will hover above 100° through midweek, with a 30–50% chance of thunderstorms developing after 4 p.m. Monday and again Wednesday afternoon.
