July 2017 ended with near normal temperatures and rainfall, with severe weather reported on only three days of the month. The most significant event took place on the 7th when a line of thunderstorms dropped southward through southern Indiana and produced winds strong enough to blow trees down. One storm managed to generate hailstones the size of golf balls in the Scottsburg area at 7:46pm.

Sweltering heat and humidity settled into the region from the 17th to the 24th, with afternoon temperature readings well into the 90s and heat index values over 100°. Morning lows were usually in the 70s, with both Louisville International and Louisville Bowman not falling below 80° on the 22nd.
