A strong low pressure system was present over the Great Lakes region to start the day on July 29th. From this extended a cold front to the southwest. As the low pressure continued eastward throughout the day, the cold front slowly shifted farther southward, before becoming elongated and slowing just north of the Ohio River. This kept much of Kentucky in the warm sector, with a strong push of warm/moist tropical air into the region. The front finally began to dip below the Ohio River as we headed into the overnight hours and transitioned to July 30th. SPC had us in a slight risk for severe thunderstorms, as showers and thunderstorms formed ahead of this frontal boundary. Many of these storms lead to heavy rainfall, and resulted in multiple instances of flash flooding. High winds were also a threat, as two severe thunderstorm warnings were issued, and numerous reports of wind damage were obtained. There was even enough low level rotation in one storm to constitute a tornado warning during the early morning hours on the 30th. Thankfully there were no reports from this.
Rainfall amounts from this event are summarized below:
