   Areas affected...southeastern Louisiana

   Concerning...Severe Thunderstorm Watch 64...

   Valid 241256Z - 241430Z

   The severe weather threat for Severe Thunderstorm Watch 64
   continues.

   SUMMARY...A damaging wind threat will continue through the morning
   across southeast Louisiana.

   DISCUSSION...A line of storms continues to move east across
   southeast Louisiana this morning with a recent 68 knot wind gust at
   KBTR at 1228 UTC near the apex of this bow. The 12Z LIX RAOB showed
   around 1250 J/kg MLCAPE with a weak near-surface stable layer and 48
   knots of 0-6 km shear. Extensive cloudcover should limit much
   heating this morning, but continued low-level moistening ahead of
   the squall line should maintain some surface based instability and a
   damaging wind threat through the morning. The northern extent of
   this severe weather threat is likely delineated by a southward
   moving line of storms/outflow boundary (currently near the MS/LA
   border). An additional watch is not currently anticipated east of
   watch 64 as any residual surface based instability will likely be
   limited to the immediate coastline by later this morning.
