Louisville, Ky. – Patchy fog and blistering heat will grip Louisville on Saturday, August 16, creating dangerous midday conditions for outdoor workers and drivers. Heat index values may reach 104°F, making hydration, shade breaks, and limiting strenuous activity critical for safety.
According to the National Weather Service, fog could develop between 7 and 8 a.m., reducing visibility on I-65 and local roads. Drivers should allow extra travel time and keep headlights on low beam. By midday, temperatures will soar to 95°F, with humidity pushing the “feels-like” temperature well above 100°F.
Sunday offers little relief, climbing to 97°F under sunny skies. Monday will be hotter still, with highs near 98°F. Cooling showers have a 20–30% chance of arriving late Tuesday and into Wednesday, potentially breaking the heat.
Residents should drink water frequently, wear light clothing, and check on elderly neighbors or those without air conditioning. Outdoor events should consider early starts or shaded setups. Pets need access to water and shelter from direct sun.
The heat will persist into early next week, with only slight nighttime cooling into the low 70s. Afternoon storms midweek may briefly lower temperatures but could also bring lightning hazards.
