Severe Storms & Flash Floods Expected for Louisville

The National Weather Service in Louisville has issued a severe weather warning, anticipating thunderstorms and potential tornadoes to impact the area on June 21. Low pressure moving into the Great Lakes region is expected to bring these conditions, with the greatest risk anticipated for areas west of Interstate 65. There is also a notable chance of flash flooding, with a 15% probability of heavy rainfall on June 21 and a further 5% chance on June 22 as the system moves east.

Wind gusts within the thunderstorms could reach 60-70 mph, and the forecast indicates the most likely area for EF1 tornadoes is southwest Indiana. The risk of severe wind in Louisville itself is between 5-14%. NWS Louisville also warns about excessive runoff potentially flooding low-water crossings. Drivers and pedestrians are advised to avoid deep water, as fast-moving water as shallow as 12 inches can sweep away small cars.

The forecast for Louisville indicates mostly sunny conditions on June 20, with a high near 85. June 21 will see partly sunny skies with a high near 87, transitioning to a 100% chance of precipitation in the evening with a low around 70, and winds up to 21 mph. Showers and possible thunderstorms are likely on June 22, with a high near 81, before clearing into sunny conditions for June 23 and 24.
