Areas affected...Portions of KY...TN...AL...GA

Concerning...Tornado Watch 127...

Valid 052051Z - 052215Z

The severe weather threat for Tornado Watch 127 continues.

SUMMARY...The severe-thunderstorm and tornado risks continue across
remaining-valid portions Tornado Watch 127.

DISCUSSION...Scattered thunderstorms continue developing along a
north-south corridor from west-central KY into central AL. This
convection is already exhibiting supercellular characteristics, and
will continue tracking eastward and northeastward during the next
several hours, capable of producing very large hail, damaging winds,
and tornadoes.

Some strong-tornado potential during the next few hours will extend
from parts of central AL to middle TN and points eastward. This is
where the influx of richest boundary-layer moisture exists (surface
dewpoints into the lower/middle 60s) supporting around 1500-2500
J/kg per modifications to the 17Z Birmingham sounding -- amid
effective SRH increasing to 200-400 m2/s2. This activity could
eventually reach into parts of western GA where air-mass recovery
continues.
