December 10th, 2021 - Tornadoes and Severe Storms - Updated 11 AM 12/17

Overview

A powerful early winter storm system brought a severe weather and tornado outbreak to a large portion of the central United States during the evening hours of December 10th and early morning hours of December 11th. Numerous reports of severe weather were received from the southern Great Lakes, south into portions of northeastern Texas and northwestern Louisiana. This included numerous tornadoes, with multiple long track and violent tornadoes recorded from portions of northeast Arkansas into Kentucky.

Across the Missouri Ozarks, supercell thunderstorms and small line segments produced numerous reports of wind damage, especially near and east of the U.S. 65 corridor. Two EF-1 tornadoes occurred across the Missouri Ozarks. One tornado occurred near Niangua with a second tornado touching down near Branson West. Multiple reports of large hail were also received, with golf ball size hail falling in the town of Everton.
