    Areas affected...Florida Panhandle...extreme southeast
    Alabama...much of southern Georgia

    Concerning...Severe Thunderstorm Watch 33...

    Valid 091058Z - 091430Z

    The severe weather threat for Severe Thunderstorm Watch 33
    continues.

    SUMMARY...The risk of brief tornadoes continues over WW 33, and may
    spread across the remainder of southern Georgia this morning.
    Depending on storm trends, a new watch could be needed farther east.

    DISCUSSION...Storms continue to track along an outflow-reinforced
    boundary, from the western FL Panhandle across far southeast AL and
    into southwest GA. Transient/embedded supercells have been noted at
    times within the SW to NE oriented line, with primarily bowing
    structures. Cells continue to move quite rapidly eastward at roughly
    50 kt.

    Surface analysis shows increasing dewpoints into southern GA, where
    pressure falls are focusing. In addition, surface winds are becoming
    gusty at 15-20 kt, indicating boundary-layer mixing and coupling
    with the stronger flow just off the surface. Indeed, area VWPs show
    500 meter winds of 35-40 kt, which is contributing to 0-1 SRH values
    over 300 m2/s2 over GA and into northern parts of the FL Panhandle.

    While MLCAPE is only averaging 500-750 J/kg, the impressive
    kinematic fields, combined with a focused corridor of storms
    suggests increasing potential of a tornado or two. Inflections
    within the line or mesolows will be favored area for brief
    tornadoes. As such, an additional watch may be needed across much of
    southern GA, essentially extending WW 33 east/northeast.
