   Areas affected...East-central Mississippi and west-central Alabama

   Concerning...Severe potential...Watch unlikely 

   Valid 252345Z - 260115Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A line of storms capable of isolated damaging winds is
   expected to continue for a few more hours.

   DISCUSSION...An arcing line of storms continues across east-central
   Mississippi with mostly ~50 mph winds and occasional wind damage.
   This MCS now has a well-developed cold pool. This will aid in MCS
   maintenance as it continues to move eastward toward a strongly
   unstable (2500 J/kg) MLCAPE) airmass. Additionally, a strengthening
   southwesterly low-level jet (40+ kts on LIX/LCH/JAN VWP) has also
   assisted cold-pool balance. This low-level jet will likely provide
   enough support to keep this line of storms going after dark, but
   eventually, the cooling boundary layer is expected to stabilize
   conditions ahead of these storms and lead to their demise.
