EF1 tornado in Union County, Mississippi

The short-lived tornado initially touched down just southwest of County Road 222. Numerous trees were snapped and uprooted at the beginning of the path. The tornado traveled northeast and damaged an outbuilding and patio at a residence. Numerous trees were uprooted on the same property. This tornado traveled up County Road 180 causing minor roof damage to several homes. The tornado lifted just north of the intersection of County Roads 180 and 222. A lone injury occurred in the same area as a tree fell on a moving vehicle with a male passenger inside. Peak winds were estimated at 90 mph.

The first significant event to produce widespread severe weather across the Mid-South for 2023 occurred on March 24, during the afternoon and evening hours. This severe weather episode occurred mainly over portions of the Lower Mississippi and Tennessee Valleys. Surface analysis for this day depicted a quasi-stationary boundary from the Mid-Atlantic States and Ohio Valley through northern portions of West Tennessee and Arkansas and stretching back through Central Texas. Low pressure tracked along the stalled front into southeast Missouri during the evening. Meanwhile, a potent mid-level trough ejected out of the southwest U.S. Upper air analysis indicated the Lower Mississippi Valley was in the right entrance region of a strong 300 mb upper-level jet streak. This produced sufficient upper-level divergence and lift needed for severe thunderstorm development.

Moderate instability combined with strong wind shear resulted in a QLCS (Quasi-Linear Convective System) convective mode. This northern part of the QLCS initially started over Western Arkansas Friday afternoon and moved east into Eastern Arkansas by early evening and then across West Tennessee. The northern part of QLCS produced scattered wind damage, flash flooding, and a weak tornado. The southern end of this QLCS scraped across north Mississippi with numerous reports of flash flooding, damaging winds, and several weak tornadoes.

The most significant storm of the night occurred during the late evening hours of March 24, as thunderstorms developing in advance of the QLCS streamed northeast Calhoun and Chickasaw Counties. A tight and small circulation developed in Chickasaw County (MS) about 5 miles east-northeast of Trebloc and quickly grew in strength as it moved into Monroe County (MS), producing significant damage from New Wren to Amory and Smithville, with the most significant damage occurring in Amory.
