Overview
A series of thunderstorm complexes during the night of June 27th into the 28th produced significant flash flooding. A small swath of rainfall amounts of 4 to 8 inches occurred over portions of northwest Kentucky, just south of the cities of Owensboro and Henderson. Surrounding this area, parts of southwest Indiana, southeast Illinois, and the Pennyrile region of western Kentucky measured 2 to 4 inches in some areas.Flooding Impacts
Numerous water rescues were conducted on the morning of June 28 in Henderson, Daviess, and Mclean Counties in western Kentucky. Local government in Mclean County declared a state of emergency. Most of the water rescues involved vehicles stranded in floodwater. At least a few water rescues involved residents in their homes in Mclean County. Rainfall amounts were highest in southern Daviess, southern Henderson, and northern Mclean Counties. This area saw as much as 7.5 inches of rain. At the height of the rainfall event, many roads were impassable, including major routes such as Highway 431.
Below is a radar-estimated rainfall map from the Evansville radar, using the dual-polarization estimates. The estimates were somewhat lower than observed values by as much as 20 percent, but they still provide a useful depiction of the hardest-hit areas. The storm-total rainfall period includes June 27th through the daytime hours of the 28th. Purple shading denotes 6-inch plus amounts, red is 5-plus inches, and yellow is 3-plus inches.
