   Mesoscale Discussion 0232
   NWS Storm Prediction Center Norman OK
   0945 PM CDT Tue Mar 24 2020

   Areas affected...northeast AL...northwest GA

   Concerning...Tornado Watch 62...

   Valid 250245Z - 250345Z

   The severe weather threat for Tornado Watch 62 continues.

   SUMMARY...If current storm-scale and near-storm environmental trends
   continue, the tornado watch can likely be cancelled within the next
   hour prior to watch expiration time, which is currently scheduled
   for 1am EDT/12am CDT.

   DISCUSSION...Radar imagery during the past hour has shown
   diminishing echo tops and storm weakening across northern AL and
   into adjacent parts of TN/GA.  Surface observations over northeast
   AL to the south of the convective cluster have shown a gradual
   veering in flow.  The 00z Atlanta observed sounding showed less than
   300 J/kg MLCAPE and buoyancy has likely lessened owing to cooling of
   the near-surface layer.  Given the aforementioned trends/factors,
   current thinking is the potential for severe will continue to
   lessen, particularly the tornado risk.  As a result, the watch may
   be cancelled early if trends continue.
