Kentucky Monthly Weather Summary

For the Period: May 2018 Record Breaking Temperatures and Below Normal Precipitation: Mother Nature seemed to flip a switch and completely skip the spring season. Looking at the official data for the month of May, 'skipping spring' seems like a good remark. May 2018 was the warmest May that Kentuckians have ever seen. 2018 now takes the top spot with an average temperature of 71.6 degrees, breaking a record that has stood since 1962. At least some part of the Commonwealth hit 90 degrees each week of the month and led the way to four straight weeks of above normal temperatures. Putting this into perspective, normal high temperatures run in the upper 70s to lower 80s for late May. In addition to the warmth, summer humidity also returned ahead of schedule. Dew points jumped well into the 60s and even into the 70s at times, further magnifying an abrupt change from a cool April to very warm May. This was a challenge not only for us, but also for animals. The above normal temperatures and high humidity pushed the livestock heat stress index into the 'Danger' category several times throughout the month. The summer-like pattern, with Kentucky situated within a moist and unstable atmosphere, led to numerous days with scattered storms developing during the day and waning at night. The month ended with the state having to deal with the remnants of Subtropical Depression Alberto moving north from the Gulf of Mexico. Even with Alberto, Kentucky saw slightly below normal rainfall for the month, averaging 4.69 inches.
