Northwest flow in the mid- and upper-levels of the atmosphere placed central Kentucky and southern Indiana on the edge of a ring of fire type pattern for several days at the end of July 2023. While most of the waves of convection remained to the north of the area thanks to building ridging aloft July 27th into the 28th, thunderstorms on July 27th clipped the Kentucky Bluegrass region. The primary impact from these storms were heavy amounts of rainfall, with over 5 inches of rain being reported at a CoCoRaHS station in Nicholas County. This resulted in scattered instances of flash flooding across Nicholas, Harrison, and Bourbon County, Kentucky late in the evening on July 27th into the early morning hours on July 28th. Sadly, one fatality resulted from a home being swept away in Nicholas County.
Otherwise, conditions were mainly quiet across the region until the early morning hours of July 29th, when a mid-level trough began to dig southwestward into the Ohio Valley, allowing a surface frontal boundary to sink closer to the region, placing central Kentucky and southern Indiana into a more convectively active domain. A bowing mesoscale convective system moved from the mid-Mississippi valley eastward into Kentucky and extreme southern Indiana during the late evening hours on July 29th. While this system was generally dissipating as it moved through the area, it still retained enough strength to cause sporadic wind damage across central Kentucky and southern Indiana.
