Areas affected...Portions of northern Alabama...southern
Tennessee... northwest Georgia

Concerning...Severe Thunderstorm Watch 617...

Valid 092042Z - 092245Z

The severe weather threat for Severe Thunderstorm Watch 617
continues.

SUMMARY...The primary hazard within WW 617 will remain damaging wind
gusts with an organized linear segment along the AL/TN border. A new
severe thunderstorm watch may be needed downstream as the airmass
destabilizes further. A tornado threat may also be developing along
the outflow from this cluster from northeast Mississippi into
northern Alabama.

DISCUSSION...An organized cluster/linear segment of storms continues
east along the Alabama/Tennessee border. With temperatures warming
into the mid/upper 80s F in parts of southeastern Tennessee and
northwest Georgia, this activity may be able to persist and pose a
threat for wind damage into these areas. A downstream severe
thunderstorm watch may be needed later this afternoon into parts of
southeast Tennessee and northwest Georgia.

Along the outflow to the southwest, one storm has initiated in
northeast Mississippi with other deepening cumulus in the vicinity.
These storms will likely be more discrete and pose a threat for a
tornado or two as well as large hail and damaging winds. Convective
trends will need to be monitored with this activity to determine if
a more substantive tornado threat will develop in the next few
hours.
