Mesoscale Discussion 1847
   NWS Storm Prediction Center Norman OK
   0906 PM CST Sun Dec 13 2020

   Areas affected...central/eastern Mississippi into central Alabama

   Concerning...Severe potential...Watch unlikely 

   Valid 140306Z - 140500Z

   Probability of Watch Issuance...20 percent

   SUMMARY...An isolated damaging-wind threat is possible with a line
   of storms quickly moving through the discussion area.

   DISCUSSION...Latest radar mosaic/objective analyses indicate a
   relatively narrow band of strongly forced convection near/just east
   of the I-55 corridor in Mississippi.  These storms were aided by
   strong forcing aloft associated with an advancing mid-level wave
   near the ArkLaTex and marginally unstable near-surface parcels. 
   Strong wind fields/shear and downward momentum processes may foster
   a few damaging wind gusts with this line as it sweeps quickly
   east-northeastward across the discussion area over the next few
   hours.  A brief uptick in intensity is possible if slightly more
   buoyant area (characterized by mid 60s F dewpoints currently across
   southeastern Mississippi/southern Alabama) can migrate northward and
   interact with the line.  A WW issuance is not anticipated due to the
   isolated nature of the threat.
