   0234 AM CST Tue Mar 03 2020

   Areas affected...northeast Arkansas...northern Mississippi and
   western Tennessee

   Concerning...Severe Thunderstorm Watch 37...

   Valid 030834Z - 031030Z

   The severe weather threat for Severe Thunderstorm Watch 37

   SUMMARY...A threat for a few severe storms will persist overnight
   ahead of the cold front.

   DISCUSSION...The primary tornado and supercell threat appears to be
   diminishing as the lifting mechanism on the large-scale shifts east
   into less unstable air. Behind the previously tornadic activity,
   storms remain along an outflow boundary which merges with the cold
   front over western TN. Surface observations as well as VWPs show SRH
   has decreased over time owing to veering low-level winds in the wake
   of the departing system. Still, temperatures aloft remain cool, with
   ample deep-layer shear, and thus hail or a few strong wind gusts
   remain possible.
