    Areas affected...Mississippi...Western Alabama...Far Eastern
    Louisiana

    Concerning...Tornado Watch 62...

    Valid 260453Z - 260700Z

    The severe weather threat for Tornado Watch 62 continues.

    SUMMARY...A wind damage and isolated tornado threat is expected to
    continue for a couple more hours across parts of eastern and
    south-central Mississippi. Weather watch issuance may be needed
    later tonight in parts of far southern Mississippi and southern
    Alabama.

    DISCUSSION...The latest mosaic radar imagery shows a linear MCS
    ongoing from east-central into southern Mississippi, with a few
    embedded strong to severe storms. The northern half of the line is
    in very weak instability with the RAP showing MLCAPE generally below
    250 J/kg. An isolated wind-damage threat may persist before the
    northern part of the line moves into western Alabama, where the
    airmass is relatively stable. Farther to the south-southwest, the
    airmass is more unstable across parts of southeastern Mississippi,
    with the RAP suggesting MLCAPE is in the 500 to 1000 J/kg range. In
    addition, RAP forecast soundings after midnight in southeast
    Mississippi have 0-6 km shear near 65 knots, with 0-3 km
    storm-relative helicity around 500 m2/s2. As the line moves eastward
    across southeast Mississippi over the next few hours, this
    environment could support an isolated tornado threat. Damaging wind
    gusts will also be possible with the more intense sections of the
    line.
