    Areas affected...eastern FL Panhandle to south GA

    Concerning...Tornado Watch 723...

    Valid 291201Z - 291300Z

    The severe weather threat for Tornado Watch 723 continues.

    SUMMARY...Potential for strong to isolated severe gusts and a couple
    brief tornadoes will primarily be focused with the trailing portion
    of an extensive QLCS across the Florida Panhandle. It appears
    unlikely to exit WW 723 before 14Z expiration. A replacement WW that
    includes downstream areas in north Florida to southeast Georgia is
    being considered.

    DISCUSSION...The trailing portion of the extensive QLCS across the
    Southeast has been the lone area to produce a measured severe wind
    gust (50 kts at ECP) this morning. This portion of the line has sped
    up its forward progression, but still appears unlikely to exit WW
    723 prior to the scheduled expiration of 14Z. This acceleration
    tendency appears to be coupled with a slowing of the west-southwest
    to east-northeast oriented, non-severe part of the QLCS in southwest
    GA. The inflection where the north/south oriented line progresses
    across the leading outflow may augment 0-1 km SRH above the
    background shear of about 25 kts per the TLH VWP. This should
    sustain a continued damaging-wind and brief-tornado threat through
    late morning.
