   The severe weather threat for Tornado Watch 47 continues.

   SUMMARY...The severe threat continues across Tornado Watch 47. A few
   damaging gusts or QLCS tornadoes remain possible.

   DISCUSSION...A QLCS continues to progress eastward across Middle TN
   amid afternoon peak heating. Surface temperatures have warmed to
   over 70 F downstream of the QLCS, supporting MUCAPE approaching 500
   J/kg. Though the HTX VAD shows a large, curved hodograph,
   boundary-layer buoyancy remains scant (as demonstrated by neutral to
   stable lapse-rates in the 18Z BNA observed sounding). As such, it is
   unclear how much of the ambient environmental SRH is effective (i.e.
   can be ingested into the leading-line updrafts). At least a threat
   for damaging gusts should persist with the progression of this line,
   though a few tornadoes remain possible given such strong low-level
   shear.
