Meanwhile, isolated severe thunderstorms are possible on Thursday from the Southeast to south-central High Plains. Finally, the ongoing heat wave continues in the West and will expand into the Rockies by the weekend. Read More >

July 2015 was a very active month, especially from the 7th through the 20th when many rounds of showers and storms crossed the region. 

Severe weather occurred in southern Indiana or central Kentucky on 11 days of the month (all but two of them from the 7th through the 20th). On the 9th a small area of gusty showers and thunderstorms around Mammoth Cave developed into a severe storm that produced damaging winds from Munfordville all the way to West Virginia. On the 12th a powerful line of storms developed over Minnesota and dove southeast, crossing southern Indiana and the Kentucky Blue Grass on the morning of the 13th accompanied by strong, damaging winds. Then later on the 13th additional showers and storms moved through the same region as the morning storms. Very heavy rain led to widespread flooding problems, including the 2nd highest stage ever recorded on the Muscatatuck River at Deputy, Indiana.

Five tornadoes struck the region during July. The first tornadoes occurred on the 10th when two EF0's struck Fort Knox. Then on the 13th a thunderstorm that moved due south from Green County to Cumberland County (and on into Tennessee) dropped two EF0 tornadoes and one EF1 tornado. The EF1 destroyed two barns and a mobile home along Ebenezer Road and KY 61 southeast of Greensburg.

The frequent rainfall kept temperatures in check for much of the month. The hottest days were the 28th and 29th with highs in the lower and middle 90s and lows only in the 70s.
