   The severe weather threat for Severe Thunderstorm Watch 391

   SUMMARY...A few damaging wind gusts up to 60-65 mph and localized
   instances of marginally severe hail near 0.75-1.25" in diameter may
   continue to accompany a linear complex of thunderstorms through this

   DISCUSSION...Latest radar and satellite imagery show an MCS
   progressing east-southeastward across portions of southern LA and
   southern MS. A moderately unstable air mass remains in place ahead
   of this system, where diurnal heating has resulted in surface
   temperatures climbing into the upper 80s and 90s, with dewpoints
   generally in the mid 70s. Recent trends from the POE VAD profiler
   indicate westerly 0-3 km shear has increased to around 50 kt over
   the past 30 minutes behind the system. This may support an
   increasing opportunity for bowing segments, and damaging wind gusts,
   oriented north-south on the eastern flank of the complex, and a
   general eastward progression into south-central/southeastern MS over
   the next 1-2 hours. In addition, brief instances of marginally
   severe hail will be possible within any of the more robust updrafts.
