Louisville is waking up to a rare summer treat on Thursday, July 23: clear skies, crisp air and temperatures around 59°F this morning, with light northeast winds and comfortably low humidity. Expect wall-to-wall sunshine and a high near 81°F this afternoon as gentle northeast breezes hang around.
Today
Thursday delivers classic “windows open” weather, with sunny and mild conditions, a high near 81°F and light northeast winds at 3–7 mph. Tonight turns partly cloudy with a low around 61°F, and things stay dry through Friday. The National Weather Service shows no active watches or warnings for the Louisville metro this morning.
Weekend
The quiet stretch starts to break down this weekend as a weak warm front drifts north and brings moisture back into the mix. There is a slight chance of showers Friday night into Saturday morning, followed by scattered afternoon and evening thunderstorms on Saturday, July 25, with temperatures trending upward. Sunday, July 26 will be noticeably hotter and more humid, with mostly sunny skies, a high near 90°F and only an isolated shower chance.
Early Next Week
By Monday, July 27, summer cranks the thermostat back up. Heat and humidity surge, with highs climbing into the low to mid 90s and heat indices pushing into the 100–105°F range in spots, especially along and west of I‑65. A couple of rounds of showers and thunderstorms are possible Monday night into Tuesday, which could briefly take the edge off the heat in some neighborhoods or make things feel even stickier depending on where storms pop up. For local cooling centers and official guidance on staying safe in excessive heat, check the Louisville Metro Government heat safety page.
What To Know And Do
Enjoy Thursday and early Friday if you like being outside, then start planning around the heat. On Sunday and Monday, keep outdoor plans flexible, aim for morning or evening activities, drink plenty of water and build in extra breaks for children, older adults and pets. If someone shows signs of heat stroke such as confusion, fainting or very hot, dry skin, seek medical help and move them to a cooler place.
