Areas affected...portions of middle Tennessee
Concerning...Tornado Watch 47...
Valid 151915Z - 152045Z
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.
