   Concerning...Severe Thunderstorm Watch 357...

   Valid 310413Z - 310545Z

   The severe weather threat for Severe Thunderstorm Watch 357
   continues.

   SUMMARY...Gusty winds and marginally severe hail will be noted with
   a squall line as it progresses across the lower Mississippi Valley.

   DISCUSSION...Long-lived MCS that developed over the southern Plains
   of TX has matured and advanced across most of LA late this evening.
   Latest diagnostic data suggests a weak short-wave trough has
   progressed into AR/LA and this feature appears partly responsible
   for the expansive nature/organization of the complex. Over the next
   few hours the leading squall line will shift east of the primary
   instability axis and gradual weakening is expected. Until then,
   gusty winds are the main risk.
