July 2023 was a very active month with severe storms occurring somewhere in southern Indiana or central Kentucky on eight different days. 

A cold front approached the region on the afternoon of the 2nd. Ahead of the front, a moist and unstable airmass combined with fairly strong wind shear aloft for the time of year. Numerous thunderstorms developed, including some supercells. EF- 1 tornadoes touched down in Anderson County and Casey County, and there were numerous wind damage reports across the area. A few instances of large hail up to the size of golf balls were also reported.

Around midnight on the night of the 17th a hailstorm produced stones to the size of ping pong balls in Louisville. 

Several Flash Flood Warnings were issued during the month as well. Shortly after midnight on the 28th heavy rains caused flash flooding on Hooktown Branch in northwestern Nicholas County that resulted in a fatality when the stream swept a home off of its foundation.
