12:05am final comments - I will stop updating the thread for tonight. Refer to the Storm Prediction Center and National Weather Service websites for updated information on watches, warnings, and mesoscale discussions. Also refer to local news livestreams below. Plus, a couple of storm chasers in the list below are still live at the time of this comment if you're interested in watching.
NOTES - I tried recreating Wazoheat's format for megathreads on this sub and will be updating this unofficial thread regularly. The Storm Prediction Center has issued a Moderate Risk for severe weather for Tuesday November 29th, 2022 for parts of the Southern United States.
A regional tornado outbreak still appears possible from northern LA into central/northern MS and potentially into western AL

Mesoscale Discussions
Discussions at the bottom of this list are the latest ones.

MD 1978 - Northern LA, extreme southeast Arkansas and into central MS

MD 1979 - Southeast TX
SUMMARY...An isolated thunderstorm or two may produce hail and gusty winds across southeast TX this afternoon. A watch is not expected at this time.
MD 1980 - extreme southeast MS into southwest AL

SUMMARY...Increasing potential for severe thunderstorms and tornadoes exists across northeast LA into central MS over the next few hours.

SUMMARY...Severe-weather risk continues across the WW area, with greatest risk for significant tornadoes evident with supercells crossing northern Louisiana at this time.
MD 1985 - for portions of southeast Arkansas into northern Mississippi and Middle Tennessee
