Overview

A strong early spring storm system impacted eastern Kentucky on March 24, 2018. Precipitation began as rain across the Lake Cumberland region during the early morning hours, while starting out as snow along and north of a line from about Lexington to Harlan. The highest snowfall amounts of 4 to 6 inches, with isolated higher amounts, occurred northeast of an Owingsville to Prestonsburg line, due to a strong dome of cold air remaining in place on the southwestern extent of a high pressure system residing from Quebec into northeastern Kentucky.

Due to the strength of this low pressure system, thunderstorms developed across portions of south central to southeast Kentucky during the afternoon and evening. Pea sized hail was observed in London with temperatures only in the low to mid 40s! Additionally, total precipitation amounts of 1.5 to over 2 inches attributed to rises on portions of the Kentucky and Cumberland Rivers.
