   Areas affected...South-central/southeast LA into southern/central MS
   and southwest AL

   Concerning...Severe potential...Watch possible 

   Valid 091649Z - 091845Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Some threat for locally damaging wind and/or a tornado may
   continue through the late morning to early afternoon.

   DISCUSSION...A storm cluster with occasional embedded rotating cells
   is ongoing this morning near the southern MS/AL border. This cluster
   is occurring within the MLCAPE gradient, along the eastern periphery
   of deeper low-level moisture that is being advected in from the
   southwest. As the buoyancy plume gradually expands eastward, this
   cluster may persist though at least late morning. While there has
   been some recent weakening of low-level flow, the KHDC and KMOB VWPs
   continue to depict low-level hodograph enlargement, and some threat
   for a brief tornado and/or locally damaging wind may continue for as
   long as this cluster persists. 

   Farther west, some increase in convection has been noted across
   south-central/southeast LA, within a moist and uncapped environment.
   While large-scale ascent will remain relatively subtle in the short
   term, modest low-level warm advection may continue to support storm
   development and maturation in this area, and also potentially
   farther north into parts of central MS, near the northern periphery
   of deeper low-level moisture. While there may be some weakening and
   veering of low-level flow with time in this area, strong deep-layer
   shear will support organized storms, including some supercell
   potential. 

   Some threat for a tornado, locally damaging wind, and possibly
   isolated hail could accompany any organized storms within the
   broader warm sector into early afternoon, though short-term coverage
   is uncertain and may remain isolated until a more substantial
   increase in severe potential later this afternoon into the evening.
