   Concerning...Severe Thunderstorm Watch 328...

   Valid 260304Z - 260430Z

   The severe weather threat for Severe Thunderstorm Watch 328
   continues.

   SUMMARY...Some wind-damage potential will spread southward late this
   evening.

   DISCUSSION...A QLCS and related outflow is surging quickly southward
   across central MS late this evening, with some southward
   acceleration also recently noted across northern LA. While moderate
   to strong buoyancy remains in place immediately downstream into
   southern MS and northeast LA, relatively weak low-level flow and
   deep-layer shear may hamper organization along the southward-moving
   QLCS segment with time. However, given the extensive surging outflow
   and rather strong pressure rises (greater than 4 mb in 2 hours), a
   loosely organized QLCS may move into parts of southern MS and
   southwest AL with time, with a continued threat of at least
   localized wind damage. Local watch expansion and/or downstream watch
   issuance may eventually be needed, depending on short-term trends.
