Mesoscale Discussion 1200
   NWS Storm Prediction Center Norman OK
   0140 PM CDT Sun Jul 12 2020

   Areas affected...South central Alabama and adjacent portions of
   western Georgia

   Concerning...Severe Thunderstorm Watch 362...

   Valid 121840Z - 122015Z

   The severe weather threat for Severe Thunderstorm Watch 362
   continues.

   SUMMARY...Further intensification of the thunderstorm cluster
   overspreading central Alabama is possible into peak heating, and the
   risk for potentially damaging wind gusts may begin to maximize
   near/north of Selma into the Auburn area by 3-4 PM.

   DISCUSSION...Thunderstorm intensity is being maintained along the
   south-southeastward advancing (30-35+ kt) conglomerate surface cold
   pool, particularly south and southeast of the mesoscale convective
   vortex which has progressed to the south of Huntsville.  Modest
   2-hourly surface pressure falls have become evident in 18Z surface
   observations, near and south of Birmingham, with roughly a 20 degree
   temperature gradient across the gust front.  

   As the pre-convective environment continues to destabilize with
   surface heating and boundary-layer moistening, additional
   intensification of storms still appears possible during the next few
   hours.  With coinciding further strengthening of the surface cold
   pool, the risk for potentially damaging wind gusts may begin to
   maximize across south central Alabama by 20-21Z.
