Louisville, Kentucky – A stretch of sizzling heat and growing storm chances will define Saturday’s weather in Kentucky, with temperatures near 91°F and afternoon thunderstorms set to disrupt outdoor plans across Louisville and surrounding areas.
According to the National Weather Service in Louisville, a Heat Advisory remains in effect until 8 p.m. Friday.
