Tornado outbreak of March 24–27, 2023

On March 24, 2023, a severe weather and tornado outbreak began across portions of the lower Mississippi River Valley in the United States. A slow-moving trough moved eastward across the United States and interacted with a moist and unstable airmass originating from the Gulf of Mexico, resulting in widespread heavy rainfall, severe thunderstorms, and significant tornadoes over a four-day period. A violent, high-end EF4 tornado moved through the towns of Rolling Fork, Midnight, and Silver City in western Mississippi, causing catastrophic damage and many fatalities. Multiple tornado emergencies were issued for that tornado and two subsequent EF3 tornadoes from the same supercell that struck Winona and Amory.

Severe weather and tornadic activity continued into the early morning hours of March 25, as a squall line of severe storms with embedded circulations moved eastward across Tennessee and Alabama. A low-end EF2 tornado within the line killed a person in the northern part of Hartselle, Alabama. The slow-moving storm system then stalled the following day, producing more severe weather and tornadoes across portions of Alabama and Georgia from March 26 to March 27, including a couple of strong tornadoes. The outbreak also resulted in numerous reports of damaging straight-line winds, hail, and flooding.
