    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.
