Louisville, Kentucky – Dangerous heat continues to smother central Kentucky as temperatures soar into the mid-90s with heat index values topping 107° by mid-afternoon Wednesday, July 30. A Heat Advisory remains in effect until 8 p.m. EDT as hot pavement and poor air circulation create health hazards — especially along heavily traveled corridors like I-64, I-65, and I-71.
According to the National Weather Service in Louisville, central Kentucky and southern Indiana will remain under heat alerts through Wednesday evening. Air temperatures near 95°F combined with oppressive humidity will produce dangerously high heat indices from 2 to 6 p.m. each day. The risk of heat exhaustion and stroke is elevated, particularly for those without air conditioning.
Drink water frequently, avoid outdoor labor during peak afternoon hours, and check on elderly neighbors. Light clothing and limited physical activity are recommended.
A 30% chance of isolated thunderstorms is expected to develop after 3 p.m. Wednesday, providing brief but scattered relief. These storms could bring localized downpours, gusty winds, and lightning. Rain chances increase further into Thursday.
