Gulf Coast magic.

Also looks like to be a decent TOR on the ground near Spencer, LA (not pictured in the image above, that was for the earlier Mississippi storm near US-49).
Sorry for the really late comment on this but why would the Gulf Coast be a better environment for tornadoes? Maybe it depends on where on the Gulf Coast you are? In Texas it definitely doesn’t feel like the Gulf Coast enhances tornado formation.
Apologies for the delay in responding, been a bit busy unfortunately.
Regarding the synoptic environment, it's more of the combination of the surface-backed winds bringing moisture onshore and the closeness of said moisture to the wide, flat swath of land which occasionally allow even shallow rainshowers to produce. It's not necessarily common, but seeing this level of onshore flow and marginal shear produce a weak tornado/waterspout or two is never out of the question.
As for geography specifics? I'm not entirely sure. My best guess is that the parallel nature of the larger Gulf of Mexico and the land of southern Mississippi allowed for that moisture flow to make its way a little further inland before getting lofted by the weak lifting mechanism and shear.
There's a lot that many people much smarter than me have discussed in detail, in which a good thread of that information and how it happened can be found here, specifically from a NWS Jackson met: https://twitter.com/DLambWX/status/1377720155086675973
