   Mesoscale Discussion 1074
   NWS Storm Prediction Center Norman OK
   0446 PM CDT Wed Jul 01 2020

   Areas affected...Southwestern Tennessee and northern Mississippi

   Concerning...Severe potential...Watch unlikely 

   Valid 012146Z - 012345Z

   Probability of Watch Issuance...20 percent

   SUMMARY...The greatest damaging wind threat for the next 2 hours
   will be from southwest Tennessee to northern Mississippi

   DISCUSSION...A mature MCS has continued southeastward throughout the
   day with occasional damaging wind reports and 40 to 50 mph measured
   wind gusts. This MCS is mostly outflow dominant (and should remain
   so based on the weak flow from the KGWX VWP). The outflow dominant
   nature of this convection will likely keep most wind speeds
   sub-severe along the line. However, the very unstable environment
   (3000 to 4000 J/kg per SPC mesoanalysis) ahead of these storms
   should provide enough fuel to maintain the MCS. There is a slightly
   higher chance for stronger wind speeds in a corridor from just east
   of Memphis, TN to Tupelo, MS. In this area, the outflow boundaries
   from the MCS across Arkansas and western Tennessee are colliding.
   This may lead to stronger updrafts in this region and a higher
   chance for some damaging wind gusts.
