6:01 AMAn EF1 tornado touched down just north of Addison along County Road 41, just north of Hunter Rd with winds of 70-80mph snapping many softwood trees. The tornado tracked east northeast and destroyed a small airplane hangar at the Addison Municipal Airport. As it tracked parallel to County Road 41, it continued to down trees with winds of 90mph. Just passed County Road 130, the tornado removed a portion of the roof from a residence. Portions of a metal roof were uplifted from an outbuilding along County Road 3725, causing minor tree damage. The tornado continued east northeast, crossing into Cullman County (See Storm Data WFO Huntsville) just south of County Road 1043. The tornado remained on the ground for an additional 2.14 miles in Cullman County.
Ahead of a strong cold front, a quasi linear convective system (QLCS) with embedded supercells moved eastward across Mississippi. Ahead of the line of thunderstorms, southerly flow increased, bringing moisture northward and increasing shear. This resulted in increased surface instabilities across much of the area, allowing storms to become surface based. Several tornadoes and widespread thunderstorm wind damage occurred across much of the area. In addition, strong gradient winds ahead of the strengthening system brought down power lines and caused minor structural damage. Heavy rainfall rates caused isolated flash flooding.
