    Areas affected...Portions of southern AL into southwest GA and the
    FL Panhandle

    Concerning...Tornado Watch 302...303...

    Valid 151622Z - 151745Z

    The severe weather threat for Tornado Watch 302, 303 continues.

    SUMMARY...The greatest severe threat in the next 1-2 hours should
    extend across parts of southern Alabama into southwest Georgia and
    the Florida Panhandle.

    DISCUSSION...The most intense convection across Tornado Watches
    302/303 should remain focused along/near a stalled boundary that
    extends from central MS into west-central/southern AL and southwest
    GA. Any supercells that can remain discrete will pose a threat for
    large hail, as moderate to strong instability and 45-50+ kt of
    deep-layer shear foster robust updrafts. There will also be some
    tendency for small clusters to develop and move east-southeastward
    along the front. This may already be occurring in southwestern AL.
    The threat for damaging winds will be greater with any cluster that
    can persist as low-level lapse rates steepen with continued daytime
    heating. The tornado threat remains less clear in the short term
    (next 1-2 hours). Latest mesoanalysis and KMOB/KTLH VWPs do show
    around 100-150 m2/s2 of 0-1 km SRH associated with a 25-35 kt
    southwesterly low-level jet. However, deviant storm motions to the
    right of the mean wind have generally not been observed this
    morning. Still, any surface-based supercell along/south of the
    boundary may pose a tornado threat, with somewhat better chances
    focused across far southeastern AL, southwest GA, and parts of the
    FL Panhandle in the near term.
