   Areas affected...Southeast TX...Western LA

   Concerning...Severe Thunderstorm Watch 353...355...356...

   Valid 310059Z - 310230Z

   The severe weather threat for Severe Thunderstorm Watch 353, 355,
   356 continues.

   SUMMARY...Locally damaging winds and marginally severe hail will be
   noted along the leading edge of southeast-moving MCS this evening.

   DISCUSSION...Long-lived MCS has matured into an expansive cluster of
   storms across much of East TX into western LA. Leading edge of this
   MCS is surging across the Sabine River over De Soto Parish, arcing
   southwest to near CLL. An MCV may be forming within the expanding
   precip shield, southeast of GGG. However, the leading QLCS is
   expected to advance across the remainder of Southeast TX, including
   the upper Coastal Plain, into southwest LA later this evening. Hail
   may approach 1 inch with this squall line, along with locally
   damaging winds. Some risk for larger hail continues with more
   isolated storms back into south-central TX.
