    Areas affected...the Florida Panhandle...southern/eastern
    Alabama...and far western Georgia.

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

    Valid 301847Z - 302015Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few strong to isolated severe storms are possible this
    afternoon and evening.

    DISCUSSION...Very strong instability (3000-3500 J/kg MLCAPE per SPC mesoanalysis) has developed across Alabama and Georgia where
    dewpoints are in the mid 70s with temperatures in the low to mid
    90s. Lapse rates are quite weak, but with minimal inhibition and
    very strong instability, robust updrafts are anticipated. Deep-layer
    shear is quite weak which will limit storm organization somewhat.
    However, there is a stronger belt of flow (25-30 knots) sampled by
    the MXX VWP between 4 and 6 km. This may assist in some storm
    organization in an otherwise unfavorable deep-layer shear
    environment.=20

    This combination of instability and some mid-level flow may result
    in a few multicell storms capable of damaging wind gusts. However, a
    more organized severe weather threat is not anticipated and
    therefore, no watch is expected.
