   Areas affected...western and middle Tennessee

   Concerning...Severe Thunderstorm Watch 510...

   Valid 220309Z - 220515Z

   The severe weather threat for Severe Thunderstorm Watch 510
   continues.

   SUMMARY...The potential for more organized severe weather appears to
   be diminishing. However, sporadic occurrences of damaging winds will
   remain possible through 05Z.

   DISCUSSION...Ongoing storms across middle TN have failed to sustain
   an organized cold pool, with only pockets of enhanced velocities
   noted in recent KOHX radar data. While latest objective analysis
   indicates the presence of a moderately unstable air mass, poor
   low/mid-level lapse rates are tempering updraft vigor. Locally
   intense downdrafts will remain capable of sporadic damaging winds
   over the next couple of hours. However, the potential for organized
   severe weather appears to be diminishing.
