Areas affected...Mississippi/Alabama

Concerning...Tornado Watch 11...

Valid 040537Z - 040700Z

The severe weather threat for Tornado Watch 11 continues.

SUMMARY...Severe wind/tornado risk will spread east across
Mississippi into Alabama over the next several hours.

DISCUSSION...Pre-frontal band of broken convection is gradually
expanding in areal coverage late this evening. Numerous
robust/severe thunderstorms extend along a corridor from southeast
LA, through east-central MS, into northwest AL. Within this
corridor, several long-lived supercells continue with one
potentially tornadic storm over Clarke County MS, moving toward
Choctaw County AL. This activity is maturing within a strongly
sheared environment coincident with a 35kt LLJ. Instability has
gradually recovered ahead of this convection with roughly 2000 J/kg
MUCAPE now evident across the southern half of ww011. Damaging
winds, along with some tornado risk, continue.
