Life-threatening, major severe weather outbreak tomorrow in the south:
A regional outbreak of severe storms is expected Wednesday into Wednesday night across portions of the lower Mississippi Valley into Alabama. Widespread severe storms capable of producing tornadoes (several of which may be intense), very large hail and intense damaging wind gusts are expected. More than one round of severe storms are possible across parts of Mississippi into Alabama during the afternoon into the overnight hours.
**An upgrade to a High risk could be necessary with the initial Day 1 Convective Outlook at 06z tonight.**
