   Mesoscale Discussion 0139
   NWS Storm Prediction Center Norman OK
   0102 AM CST Tue Mar 03 2020

   Areas affected...northern middle Tennessee into southeast Kentucky

   Concerning...Tornado Watch 36...

   Valid 030702Z - 030900Z

   The severe weather threat for Tornado Watch 36 continues.

   SUMMARY...A tornado threat may persist for a few more counties east
   and northeast of the Nashville area. Damaging wind gusts are also
   possible, possibly extending into southern Kentucky.

   DISCUSSION...A long-lived supercell, now with a confirmed,
   potentially intense tornado, continues to move east across the
   Nashville area. This southern-most supercell is on the southern
   fringe of the larger-scale area of ascent, and firmly within the
   local effective SRH maximum where values over 500 m2/s2 exist. 

   Surface observations indicate a plume of mid 50s F dewpoints extends
   east/northeast of this storm, and while instability weakens with
   eastern extent, strong shear may allow these storms to persist for
   at least an hour.
