Afternoon Update

I expect the highest instability from the west will continue to filter into the Pine Belt. Storms developing late this evening and after sunset could be fed with enough usable energy to produce damaging wind and hail. An isolated tornado is still plausible, but highest storm relative vorticity (rotation variable) is greatest along the MS and LA coastline.

There is currently significant rotation indicated on radar with a supercell in Louisiana at this time, but I'm pretty sure there is no verification the rotation has reached the ground. The whole line in Louisiana will be migrating into South Mississippi in the next several hours.
