Louisville, Kentucky – A summer weather alert is in effect as Louisville braces for sweltering heat Saturday, with temperatures expected to climb near 96°F. The National Weather Service warns that prolonged outdoor activity could pose health risks during peak afternoon hours.
According to the NWS in Louisville, calm winds and clear skies will dominate much of the weekend. Saturday and Sunday will remain hot and dry, with highs near 95°F and overnight lows hovering in the low to mid-70s. Southeast and light variable winds offer little relief from the heat. Residents should limit outdoor work, drink water regularly, and check on vulnerable neighbors and pets.
By Monday, storm chances return. A 40 percent chance of showers and thunderstorms is expected Monday afternoon, especially after 2 p.m. Tuesday night into Wednesday brings the highest likelihood of wet weather, with storms possible after 2 a.m. Tuesday and continuing into Wednesday morning.
The heat will persist through midweek, with highs in the low 90s and scattered afternoon storms likely each day. Roadways such as I-64 and I-65 could be slick during storm periods, and power disruptions are possible with stronger cells.
What’s next: A more unsettled pattern continues into Thursday and Friday, with 50–60% storm chances and highs near 88–91°F. Thunderstorms may impact outdoor events and evening plans through late next week.
