Event Narrative

An EF0 tornado developed just downstream of the microburst wind damage south southwest of Nauvoo. This tornado moved east northeast, crossing Slick Lizard Rd. A mobile home sustained moderate damage due to a downed tree. The tornado continued east northeast, causing shingle damage to a home and destroying an outbuilding. The tornado lifted after crossing Alabama Highway 5. Along the path, dozens of hardwood and softwood trees were uprooted or snapped.

Episode Narrative

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.
