Twitter has safe tornado videos at #kywx and probably other #/@ tags. Atmosphere has tipped its hand on the synoptic fronts. How about boundaries farther south? They are usually second to go; so, this is very much still an ongoing day for Dixie (as of Noon Central Time). Noon Central Time: Differential heating and dewpoint boundary is noted from North Alabama into West Tenn. Another boundary is lifting from central Mississippi. They may merge later farther north. Either way looks like locally enhanced helicity in the usual suspect areas of North Alabama into northeast Mississippi and southern Middle Tenn. Upper air wind fields are strong including proper turning with height. 700 mb is a little warm; but, I expect enough surface convergence to overcome. Synoptic trough is coming out of Arkansas, and will bump into the above boundary(ies). North Bama clouds are decreasing both sides of lifting boundary, an ominous sign. Oh that boundary looks like an extension of the Georgia cool wedge-front, where clearing is also seen both sides. Warm mid-levels and neutral heights from yesterday will have less impact if foretasted surface heating materializes. Plus convergence along boundaries should be enough, esp intersecting ones.
