As a potent shortwave trough moved across the southern portions of the country, it was met with ample moisture return and destabilization, resulting in widespread severe thunderstorms that produced damaging winds, hail, and tornadoes.
The first advertised threat for organized severe weather came on November 26, when the Storm Prediction Center (SPC) outlined a day 5 risk area across portions of the Southern Plains.
Despite a confined warm sector, the combined influence of moderate CAPE around 500–1,500 J/kg, an 850 mb (hPa) jet stronger than 50 kn (58 mph; 93 km/h), low lifted condensation levels (LCLs), cold temperatures aloft (steep lapse rates), weakening convective inhibition (CIN), and persistent moisture transport (warm-air advection (WAA)) resulted in the formation of semi-discrete supercells and quasi-linear convective systems (QLCSs) that resulted in widespread damaging wind reports and several tornadoes.
[6][7] In Oklahoma, a large and long-tracked EF2 wedge tornado impacted areas near Tenkiller Ferry Lake, damaging or destroying many homes and other structures, downing countless trees, and injuring 5 people.
[8] During the very early morning hours of December 1, an EF1 tornado struck the southern part of Aurora, Missouri, killing one person at a motel and damaging a few other nearby businesses.
The aforementioned shortwave progressed into the Mississippi River Valley, supporting the formation of a secondary surface low pressure over Missouri that moved toward the Great Lakes.
This included strong EF3 tornado that struck the Naval Submarine Base Kings Bay in Camden County, Georgia, tossing heavy objects and injuring four people.
