   Mesoscale Discussion 0839
   NWS Storm Prediction Center Norman OK
   0953 AM CDT Fri Jun 05 2020

   Areas affected...Northern AL...Far Northeast MS

   Concerning...Severe potential...Watch unlikely 

   Valid 051453Z - 051700Z

   Probability of Watch Issuance...5 percent

   SUMMARY...An isolated damaging wind gust or two is possible over the
   next few hours.

   DISCUSSION...Recent surface analysis and visible satellite imagery
   reveal an outflow boundary extending from extreme northeast MS
   (about 35 miles west of MSL) arcing southeastward and then eastward
   across northern AL (about 30 northeast of GAD). Ample low-level
   moisture and surface heating ahead of this boundary has resulted in
   quick air mass destabilization. Convective initiation has recently
   occurred along the far northwest portion this boundary. Gradually
   increasing storm coverage is expected along this boundary over the
   next few hours as downstream buoyancy continues to increase. Area
   VADs and BMX 12Z sounding reveal very weak flow throughout much of
   the troposphere, with weak vertical shear as a result. Consequently,
   a predominantly pulse multicell mode is anticipated. An occasional
   water-loaded downburst may be strong enough to produce damaging wind
   gusts, but overall severe potential appears minimal.
