   Mesoscale Discussion 0073
   NWS Storm Prediction Center Norman OK
   0828 PM CST Thu Feb 06 2025

   Areas affected...Portions of eastern Tennessee...Kentucky...and far
   western Virginia

   Concerning...Severe Thunderstorm Watch 4...

   Valid 070228Z - 070330Z

   The severe weather threat for Severe Thunderstorm Watch 4 continues.

   SUMMARY...Scattered severe thunderstorms will continue to progress
   eastward across portions of eastern TN over the next hour. Hail up
   to the size of golf balls, damaging wind gusts exceeding 60 mph, and
   a tornado or two remain possible.

   DISCUSSION...Latest radar imagery shows two dominant supercells
   moving ESE near Rutledge and Knoxville, TN. These right moving
   storms have exhibited rotation in the lowest levels over the past
   30-60 minutes, and are located within a buoyancy axis extending
   southwest to northeast. This is also where stronger southwest flow
   just above the surface (40-50 kt) continues to be observed via the
   MRX VWP, yielding 0-1 km SRH of 300-350 m2/s2. This area of both
   enhanced instability and low level shear should continue to favor
   supercells for at least another hour, with a threat of damaging
   winds, hail, and perhaps a tornado.
