    Areas affected...southern Mississippi into far eastern Louisiana

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

    Valid 092342Z - 100145Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A storm or two may persist this evening in the short term.
    Coverage and longevity of severe potential is not expected to
    warrant a watch.

    DISCUSSION...Daytime heating and upper 60s F dewpoints have led to
    moderate instability over the northern Gulf Coast area with MUCAPE
    around 2000 J/kg. While the primary lift is with the wave moving
    across northern AL, scattered storms persist extending southwestward
    across much of MS and into eastern LA.

    The VWP from HDC shows veering winds with height, with 35-40 kt
    effective shear, as well as 0-1 km SRH near 100 m2/s2. Given the
    uncapped air mass and favorably shaped hodograph, some cells have
    exhibited supercell characteristics at times.

    As the boundary layer begins to cool this evening, the number and
    intensity of cells is expected to decrease. In the short term,
    localized hail, a brief tornado or strong gusts cannot be ruled out.
