Summary of severe weather on Saturday, including the Dexter tornado

Overview

Clusters of thunderstorms developed during the late afternoon hours. Some of the largest clusters were associated with sporadic gusty winds in the 40 to 60 mph range. By early evening, a few tornadic circulations were observed as storms intensified. A significant tornado occurred in southeast Missouri. In fact this was the strongest tornado in the month of July for our area since 1971. By late evening, storms became widespread, resulting in pockets of flash flooding which continued through the overnight hours.

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

Wind & Hail:

Wind

Sporadic reports of strong winds were received. Most of the wind reports were in the 40 to 60 mph range. The most organized storm clusters developed a "gust front" that brought down tree limbs and even a few whole trees.

Hail

Hail was relatively insignificant compared to the tornado, wind, and flooding hazards.

Flooding

A narrow corridor of excessive rainfall occurred where storms trained across the same areas for several hours. Radar estimated 6 to 9 inches fell in a narrow corridor of west Kentucky from central Livingston and Caldwell Counties eastward across the Christian - Hopkins County border area. There were a few confirmed rainfall measurements of 7-plus inches in southern Crittenden County.
