   Areas affected...southeast MS

   Concerning...Severe potential...Watch unlikely 

   Valid 241742Z - 242015Z

   Probability of Watch Issuance...20 percent

   SUMMARY...An isolated risk for a damaging gust or two and a brief
   tornado will focus over southeast MS near the I-59 corridor through
   2pm CST.

   DISCUSSION...Midday visible satellite/radar mosaic shows dense cloud
   cover over the central Gulf Coast and a squall line from southeast
   LA northeastward into east-central MS.  The cloud canopy has limited
   heating but slow destabilization is occurring over southeast MS as
   temperatures rise into the upper 60s to lower 70s from the mid 60s
   earlier this morning.  Additionally, surface observations near
   Hattiesburg have shown dewpoints rising from the mid 60s to the
   upper 60s during the past few hours and thereby contributing to weak
   surface-based instability developing ahead of the squall line. 
   Coincident with the increase in buoyancy has been a slow but gradual
   intensification of the convective line (i.e., echo tops, surges and
   inflections becoming more prevalent).  Given the general parallel
   character of the deep-shear vector to the squall line/larger-scale
   gust front orientation, it seems likely that any appreciable threat
   for strong to locally severe storm activity will occur with portions
   of the line becoming slightly more orthogonal with respect to the
   deep-shear vector and gust front.  A couple of damaging gusts and
   perhaps a brief tornado may occur as the airmass continues to slowly
   become more favorable these thunderstorm hazards over the next few
   hours.
