   Mesoscale Discussion 0522
   NWS Storm Prediction Center Norman OK
   0731 AM CDT Tue May 04 2021

   Areas affected...Middle Tennessee and adjacent northern Alabama

   Concerning...Severe Thunderstorm Watch 141...

   Valid 041231Z - 041400Z

   The severe weather threat for Severe Thunderstorm Watch 141

   SUMMARY...Severe risk is focused across northern Middle Tennessee at
   this time, with downstream areas being monitored.

   DISCUSSION...Latest radar loop shows an organized band of
   thunderstorms -- and associated outflow -- moving eastward across
   Middle Tennessee, while outflow from storms across southern Kentucky
   moves southward.  The most vigorous convection is ongoing near the
   intersection of these two outflow boundaries intersect -- i.e. over
   northern Middle Tennessee.  An area of rotation within the broader
   band of convection continues, and is now over western Jackson
   county.  While a brief tornadic spin-up remains possible here, and
   elsewhere along the leading edge of the convective band, potential
   for locally damaging winds will continue/shift eastward across WW
   141 this morning, through a favorably unstable/amply sheared
