Strong to severe storms formed along and south of Interstate 44 during the evening of the 5th, as a southeastward moving cold front interacted with an unusually unstable airmass over the region. Sufficient vertical wind shear was also present, leading to the development of supercells embedded within a line of storms from northeast Oklahoma eastward into northern Arkansas and southern Missouri. Reports of up to golf ball size hail were received near Table Rock Lake. One EF-1 tornado developed near Highlandville in Christian County, and caused damage to trees and outbuildings.
