   Concerning...Severe Thunderstorm Watch 230...231...

   Valid 192211Z - 192315Z

   The severe weather threat for Severe Thunderstorm Watch 230, 231
   continues.

   SUMMARY...A few severe gusts may still occur with the stronger storm
   cores for the next few hours.

   DISCUSSION...Multicellular convection is congealing into a
   semi-organized line of storms, with a history of at least a few
   damaging gusts. These storms continue to progress eastward ahead of
   a surface cold front, where surface temperatures in the mid 80s F,
   amid 60s F dewpoints, are yielding 1500+ J/kg MLCAPE. Vertical shear
   is relatively weak. Nonetheless, the coverage of storms amid the
   aforementioned buoyancy suggests that at least a few more damaging
   gusts may occur over the next few hours.
