EF1 tornado in Chickasaw County, Mississippi

The tornado began near County Roads 173 and 182 southwest of Egypt in far eastern Chickasaw County. It traveled northeast across County Road 179, causing numerous snapped and uprooted trees. This tornado moved into Monroe County as it crossed Highway 45 near the intersection of Old Houston Road. Peak winds were estimated at 95 mph in Chickasaw County.

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.
