    Areas affected...parts of the Florida Panhandle...southeastern Alabama...adjacent southwestern Georgia

    Concerning...Severe potential...Watch unlikely=20

    Valid 252220Z - 260015Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The development of occasional supercell structures posing
    a risk for brief, weak tornadoes may continue into early evening.=20
    Due to the marginal/limited nature of this potential, it is not
    clear that a severe weather watch is needed, but trends are being
    monitored.

    DISCUSSION...A modest belt of mean southerly ambient flow (on the
    order of 20-30 kt) has developed inland across Alabama and Florida
    Panhandle coastal areas, in association with a northeastward
    migrating remnant mesoscale convective vortex to the northwest.=20
    This has contributed to wind profiles including modest low-level
    hodographs with clockwise curvature, along a low-level confluence
    band which is providing a focus for vigorous thunderstorm
    development extending west of Crestview FL southward offshore.

    This convection is being supported by inflow of near saturated,
    seasonably moist (including surface dew points in the lower/mid 70s
    F) boundary layer air supportive of sizable CAPE up to around 2000
    J/kg. And the environment has become conducive to supercell
    structures with potential to produce brief/weak tornadoes. Given
    the marginal nature of the wind profiles, the the enhancement of the near-surface buoyancy, and potential upward parcel accelerations,
    associated with the higher moisture content has probably been
    necessary to support this activity. It is possible that this could
    continue another few hours and perhaps spread a bit farther inland.
