Although this summer started off dry with drought conditions in the Blue Grass, we entered an active pattern by mid-June that lasted into early August. From June 25 to August 12 the region averaged a severe weather event every three and a half days. Storms brough torrential rains, large hail, strong winds, and a total of eleven tornadoes. The strongest twister was an EF-2 that struck Hardin County about three miles west of Cecilia on June 25.

The season ended up being slightly on the cool side for many locations. Louisville had its fewest 90 degrees days in the June-August period since 2009. Summer did end on a hot note, though, as a heat wave swept through the region August 21-26. Temperatures reached the 90s each day, culminating on the 25th with some locations approaching 100°. Dew points from the mid 70s to low 80s on the 25th led to heat index readings over 110°.
