    Areas affected...Portions of southern AL/south GA into north FL and
    the FL Panhandle

    Concerning...Severe Thunderstorm Watch 281...

    Valid 131942Z - 132145Z

    The severe weather threat for Severe Thunderstorm Watch 281
    continues.

    SUMMARY...Damaging winds and large hail will continue to be a threat
    with thunderstorms spreading eastward through this evening.
    Downstream watch issuance into parts of southeast/coastal Georgia
    and north Florida is possible.

    DISCUSSION...Multiple thunderstorm clusters are ongoing across
    southern AL/southwest GA and the FL Panhandle this afternoon.
    Moderate to strong instability is present across these areas
    along/south of a stationary front. Although mid-level winds do
    weaken slightly with southward extent into north FL, area VWPs do
    show gradually strengthening mid-level westerly winds to around
    30-35 kt. Similar values of deep-layer shear should be enough to
    continue supporting a mix of multicell clusters and perhaps
    occasional marginal supercells. Both large hail and damaging winds
    will continue to be a threat as this convection spreads eastward
    over the next few hours. The risk for damaging winds may increase if
    additional thunderstorm clustering occurs as low-level lapse rates
    steepen further. Based on recent convective trends, additional watch
    issuance into parts of southeast/coastal GA and north FL is
    possible.
