As a cluster of storms is brewing in parts of central Louisiana, slowing drifting east-southeast.

That radar grab was from about 10:30am.
Quick update
We’ve had a few changes to the forecast since 2am…
1. The tornado threat should be confined to the south side of the cluster of storms that is moving toward the area. And, based on the trajectory, that threat should remain south of HWY 98 in South Mississippi.
The tornado threat will also be for EF-2 or weaker tornadoes. It looks like EF-3s or stronger will be pretty difficult to produce. I suppose it isn’t out of the realm of possibility, but man, it looks really unlikely.
2. The large hail threat is decreasing. While that doesn’t mean you won’t see any hail, I think the damaging hail (the stuff bigger than 2″ across) looks less likely today than it did this morning.
Timeline
Someareas have already started to see rain (based on the radar above). This rain so far has been the non-severe storms.
As we move past 11am, the threat for severe weather will increase across all parts of south Mississippi. If you live south of I-20 and east of I-55, this includes you. Yes, even for your town. While it might simply take a bit longer to get there, you will eventually have the threat for severe weather.
All of this should pass through by about 6pm.
