The Ozarks were on the western edge of a severe thunderstorm and tornado outbreak that occurred from the evening of the 10th to the early morning of the 11th. A very unstable and highly sheared airmass interacted with a strong cold front and upper level disturbance to spark the widespread storm activity. According to the NWS Storm Prediction Center, 121 tornadoes occurred from southwest Missouri eastward into northeast Arkansas, Kentucky, Tennessee, and Illinois.  Three tornadoes, each rated EF-1, occurred near West Branson, Walnut Shade and Niangua. In addition, there were over 30 reports of damaging wind gusts over 60 mph, and several reports with hail up to golf ball size. Due to the fast movement of the storms, rainfall accumulations were generally one half inch or less.
