    Areas affected...Central MS

    Concerning...Severe Thunderstorm Watch 298...

    Valid 211116Z - 211315Z

    The severe weather threat for Severe Thunderstorm Watch 298
    continues.

    SUMMARY...A marginal risk for damaging winds will continue through
    early morning across central Mississippi, though trends suggest an
    overall diminishing trend in the severe-weather threat across the
    remainder of WW 298, and this watch could be cancelled prior to 15Z.

    DISCUSSION...Since 10Z, trends in mosaic radar imagery showed the
    leading portion of the cluster of storms moving southeast into
    central MS had begun to decelerate from an earlier fast storm motion
    at 50 kt to a current motion of 35 kt. Storm reflectivities were
    undergoing substantial weakening per mosaic imagery and most CAPPI
    levels. These trends are all indicating that the objectively
    analyzed strong surface-based inhibition is and will continue to
    limit the potential for new storm development into the early
    morning.
