   Concerning...Severe Thunderstorm Watch 94...

   Valid 131944Z - 132145Z

   The severe weather threat for Severe Thunderstorm Watch 94
   continues.

   SUMMARY...Severe risk continues -- mainly over coastal areas of
   southern Louisiana.

   DISCUSSION...Latest radar loop shows outflow from widespread inland
   convection now moving southward toward/off the southern Louisiana
   Coast, and is expected to clear all Parishes west of the river in
   the next 1 to 2 hours.  Greatest ongoing severe risk remains with
   the more surface-based storms near this outflow -- across
   Terrebonne/Lafourche/Jefferson/Plaquemines Parishes, where large
   hail and locally strong/possibly damaging gusts may occur.

   Elsewhere, weaker storms in a warm-advection regime north of the
   outflow are increasing across south central Louisiana.  While some
   hail cannot be ruled out, the greater risk should taper off as
   outflow advances into the northern Gulf of Mexico.
