Harrison County Flood History

Flash Flood — Jul 27, 2023

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 prima...

Flash Flood — Jan 3, 2023

During the overnight hours and into the morning on January 3rd, a strong system moved across central Kentucky, bringing isolated damaging wind gusts and widespread heavy rainfall. The system was associated with a negatively-tilted upper-level trough which moved from the Four Corners region on January 2nd to the upper Midwest by January 4th. A surface cyclone transited in a similar fashion to th...

Flash Flood — May 6, 2022

During the morning hours of May 5th, a surface warm front moved northward through central Kentucky before becoming nearly stationary near the Ohio River. South of this boundary, the atmosphere destabilized during the afternoon hours, allowing for clusters of strong to severe thunderstorms. Rain persisted across the region overnight from the 5th into the morning of the 6th as the surface low mov...

Flood — Feb 28, 2021

A stalled frontal boundary brought waves of heavy rainfall to central Kentucky from February 26 through February 28. This caused record rainfall, isolated severe winds, and even a tornado. As a result, Bowling Green set a February daily rainfall record with 5.11 on the 28th. The severe winds brought down some trees and a power pole, but the most property damage came from a brief EF1 tornado.

Flash Flood — May 24, 2020

May 23, warmer temperatures surged into central Kentucky and southern Indiana behind a northward moving warm front. The surge of warm moist air resulted in scattered thunderstorms producing wind damage that occurred for three days from Logan County to the Bluegrass region of Kentucky. Besides mostly tree damage, there were reports of severe hail and isolated flooding.
