    Areas affected...parts of southern AL...southwest/central GA...into
    the western FL Panhandle

    Concerning...Tornado Watch 132...

    Valid 062048Z - 062215Z

    The severe weather threat for Tornado Watch 132 continues.

    SUMMARY...Several bands of strong to severe storms will remain
    capable of damaging gusts and a couple tornadoes. Some local
    extensions of WW132 may be needed, but the downstream threat appears
    more limited.

    DISCUSSION...As of 2040 UTC, regional radar observations indicate a
    band of convection across southeastern AL and west-central GA
    continues to show embedded supercell and bowing structures capable
    of damaging gusts and tornadoes. This should continue for a couple
    more hours as storms approach the eastern edge of the Tornado Watch
    132. Areal extensions of a few counties may be needed as storms
    begin to outrun the watch. As storms continue farther east, a
    gradual decrease in buoyancy should favor weakening into the evening
    hours. Until then, damaging gusts and a couple tornadoes remain
    possible.

    To the southwest, a second smaller band of convection across
    southern AL will likely maintain intensity for a few more hours this
    afternoon. A few more isolated cells have also developed farther
    east within the warm sector across southwest GA and the northern FL
    Panhandle. 1500-2000 J/kg of MLCAPE and 40+ kt of effective shear
    could support a continued severe threat into this evening. This
    matches with some hi-res guidance that shows a gradual expansion of
    strong storms into southwest GA and possibly northern FL. However,
    forcing for ascent is some what nebulous and storm coverage has
    remained more isolated thus far. With storms approaching the
    southeast corner of WW132 in the next few hours, some consideration
    may be given to a small downstream watch. However the extent of the
    severe risk and need for any new watches is currently unclear.
