A mesoscale convective complex moved southeast and passed through northeast Kentucky during the afternoon hours on the 13th.
More thunderstorms formed in northern Ohio ahead of a cold front and mid level disturbance during the midday and early afternoon on the 14th.  These storms formed into a squall line and moved southeast, through northeast Kentucky during the late afternoon and early evening.  Wind damage occurred,causing electrical power outages. Also, flash flooding and river flooding were seen due to the saturated soils and streams running well above normal mid summer flows.
This episode, combined with the July 18th and 19th episode, qualified both Carter and Lawrence Counties in the federal disaster that was eventually declared for several counties in Kentucky.  See FEMA disaster 4239 for more details.
