Areas affected...central and northern AL...southern middle TN

Concerning...Tornado Watch 50...

Valid 260000Z - 260030Z

The severe weather threat for Tornado Watch 50 continues.

SUMMARY...A new tornado watch will likely be issued by 730-745pm CDT
and effectively replace the ongoing PDS tornado watch set to expire
at 800pm CDT.

DISCUSSION...Radar mosaic shows several clusters of storms across AL
and a band of storms near the TN/MS/AL border as of 7pm CDT.
Although a considerable amount of convection has led to rain-cooled
temperatures and a reduction in instability over north-central and
northern AL, a moist and adequately unstable airmass remains in
place given the presence of mid 60s dewpoints near the TN border to
upper 60s over south-central AL.  Very strong low to mid-level flow
will conditionally support updraft rotation with established/mature
updrafts.  It appears the overall severe risk has lessened compared
to earlier this afternoon, but isolated large hail, damaging gusts,
and a tornado threat will probably persist through much of the
evening.  It is unclear whether more than a few storms will pose a
severe risk, but the environment will at least favor some potential
for severe.
