   Areas affected...portions of middle into eastern Tennessee

   Concerning...Tornado Watch 47...

   Valid 152056Z - 152230Z

   The severe weather threat for Tornado Watch 47 continues.

   SUMMARY...The severe threat may continue downstream of Tornado Watch
   47 into eastern TN. An additional WW issuance may be needed
   downstream pending favorable convective trends.

   DISCUSSION...A QLCS continues to progress across Middle TN, and is
   approaching the eastern bounds of Tornado Watch 47. Downstream,
   surface observations show surface temperatures exceeding 70 F amid
   upper 40s to low 50s dewpoints. Given 20+ F surface
   temperature/dewpoint spreads, a deeper, potentially drier boundary
   layer may be in place, which may augment damaging gust potential.
   Given large, clockwise curved hodographs (per regional VADs), QLCS
   tornado potential may also exist. As such, a downstream WW issuance
   may be needed if QLCS organization and intensity persists or
   especially increases.
