The summer of 2010 will certainly be remembered for its heat. Louisville had its overal hottest summer on record, and the summer ranked as #3 at Bowling Green and #5 at Frankfort and Lexington. While it's true that the temperature at Louisville International Airport tends to be higher than other area temperatures due to its urban location, Bowman Field, in a more suburban setting of Louisville, had an average temperature that would still rank as the #2 hottest summer on record for Louisville, and by only 0.4°.
An interesting aspect of the summer heat this year was how warm the nights were. Bowling Green didn't set a single record high this summer, but the city did experience seven record warm lows. Frankfort and Lexington also set no record highs but did attain three record warm lows each.
Severe weather was relatively sparse this summer, with most of the severe weather coming in the form of strong gusty winds from scattered large afternoon thunderstorms. There was one tornado...an EF0 in Adair County on the evening of June 9. The twister knocked down trees and destroyed a barn near Columbia.
Some of the storms that formed in the hot, humid air produced copious amounts of rainfall. On July 27 Berea was submerged by 4 to 6 inches of rain, which flooded streets and resulted in at least one water rescue. Then on August 18 showers and storms with very heavy rain caused flooding from Monroe County to the Lake Cumberland region as numerous storms repeatedly moved across the same areas.
