Thunderstorm Wind in Knox County, Kentucky

A tree was reported down off of Sand Lick Road near the community of Sprule, Kentucky.

A surface low was situated over Iowa/Illinois/Missouri during the day of the 18th, with a warm front extended eastward and across and just north of the Bluegrass State. SPC had placed much of our area in a marginal risk of severe weather early in the day, before upgrading to a slight category during a morning update. A secondary low also developed and moved into the state for the afternoon, creating a secondary warm front boundary - along which lift and all modes of severe weather were possible, with the best chances for wind and hail. There was enough low level sheer that an isolated tornado couldn't be ruled out. As a shortwave trough also approached eastern KY throughout the day, along with an MCS to our west, the atmosphere was primed for severe weather to occur across the southeastern portions of the CWA.
