The episode as NWS LMK wrote it up.
A warm front stretching across southern Indiana and far north central Kentucky moved farther north during the daytime hours. This left central Kentucky in a warm moist unstable atmosphere with dew point temperatures in the lower to mid 70s. While numerous showers developed across central Kentucky only a couple of them produced damaging wind gusts.
