![]() ![]() ![]() The watch mentioned the possibility of several strong to intense tornadoes with any persistent supercells. CDT for portions of eastern Arkansas, northeastern Louisiana, central and northern Mississippi, and western Tennessee. A tornado watch was issued shortly thereafter at 5:15 p.m. Initial forecaster thinking was that strong forcing for ascent across Arkansas would lead to an organized squall line capable of both tornadoes and damaging winds, whereas more discrete supercells would be possible farther south, particularly along north–south oriented confluence bands in the open warm sector. ![]() Thus, mixed-layer convective available potential energy was expected to rise into the 1,500–2,000 J/kg range. Although some reduction in moisture was expected across Mississippi due to drier air aloft and warm surface temperatures into the 80s ☏, continued advection of moist air from the Gulf of Mexico seemed supportive of dewpoints in the upper 60's and lower 70's across Louisiana, Arkansas, and Mississippi by the evening hours. Meanwhile, a rapidly deepening low-pressure area was expected to drag a warm front northward, leading to a broad, unstable air mass to its south. The trough was expected to move quickly eastward, accompanied by strong mid-level winds between the trough and strong high-pressure area across the Southeastern United States. On the morning of March 24, water vapor imagery depicted a potent mid-level trough over northern portions of the Baja California peninsula. The Enhanced risk was expanded northward the following day, and the original outlined area was upgraded to a level 4/Moderate risk. On March 22, the SPC issued a level 3/Enhanced risk of severe weather across portions of Louisiana, Arkansas, and Mississippi, for supercell thunderstorms capable of large hail, damaging winds, and strong (EF2+) tornadoes. įarther to the east across the lower Mississippi River Valley, a more substantial threat for severe weather unfolded. In addition, two EF1 tornadoes occurred in Parker County, Texas, during the morning hours of March 24. Scattered reports of large hail and damaging wind gusts were received from Texas across into the Mid-Atlantic states. By March 23, a level 2/Slight risk was hoisted from Texas northeastward into Missouri, primarily for the threat of large hail. Additional risk areas were issued to the east in later outlooks, concurrent with the eastward-moving trough. On March 18, the Storm Prediction Center (SPC) first indicated the potential for organized severe weather across the Southern Plains in advance of an upper-level trough across the Western United States. GOES-16 satellite image of the storm system responsible for the tornado outbreak across the Southern United States at 14:06 UTC (9:06 a.m. The outbreak also resulted in numerous reports of damaging straight-line winds, hail, and flooding. 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. 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, spawning a low-end EF2 tornado that killed a person in Hartselle, Alabama. Multiple tornado emergencies were issued for that tornado and two subsequent EF3 tornadoes from the same supercell that struck Winona and Amory. 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. 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. On March 24, 2023, a severe weather and tornado outbreak began across portions of the lower Mississippi River Valley in the United States. Part of the tornado outbreaks of 20–23 North American winterġ Most severe tornado damage see Enhanced Fujita scale ![]()
