The Work Week will Begin with Unsettled Weather from the Southern Plains to the Great Lakes

Unsettled weather is forecast to continue through the first half of the work week from the Southern Plains to the Great Lakes as a frontal system moves through. Isolated to scattered severe thunderstorms and flash flooding will be possible each day. Meanwhile, scattered showers and thunderstorms are expected across the Southwest and California, with isolated flash flooding possible. Read More >

Overview

An upper level low over the southern great lakes helped to generate several rounds of showers and storms across east Kentucky on July 20th.  Plentiful moisture moved northward into the Ohio river valley thanks to modest southerly flow.  With ample daytime heating, explosive thunderstorm development was seen across central and eastern Kentucky.  While a tornado and hail threat was seen initially across central Kentucky, the wind threat took over as thunderstorms evolved into a line of storms.  Many reports of storm damage were received with the most extensive damage occurring along and north of the Mountain Parkway, particularly in Montgomery County where Emergency Management reported that 47 roads were closed at one point due to downed trees and power lines resulting in nearly 4,600 power outages. Additionally, a disaster declaration was made for the county as multiple buildings sustained damage. These included a tobacco warehouse that had its roof blown off as well as a hotel in Mount Sterling whose sign and building both sustained damage from severe straight-line winds.
