    Areas affected...Southern Mississippi...Southern Alabama...Western
    Florida Panhandle

    Concerning...Severe potential...Watch likely=20

    Valid 130934Z - 131030Z

    Probability of Watch Issuance...80 percent

    SUMMARY...A wind damage, hail and an isolated tornado threat will be
    possible for several more hours, as a line segment moves
    east-southeastward from southern Mississippi into southern Alabama
    and the western Florida Panhandle. Weather watch issuance will
    likely be needed.

    DISCUSSION...The latest hi-resolution radar from Jackson, MS shows
    an organized line segment moving east-southwestward across southern Mississippi. This line is being supported by a shortwave trough,
    evident on water vapor imagery, and is located along a gradient of
    instability, where the RAP has MUCAPE in the 500 to 1000 J/kg range.
    Along this west-northwest to east-southeast corridor, regional
    WSR-88D VWPs and RAP forecast soundings have 0-6 km shear in the 60
    to 75 knot range. This should continue to be favorable for storm
    organization for several more hours. Wind damage will be possible
    along the leading edge of the line. In addition, the WSR-88 VWP at
    Fort Rucker, AL has 0-3 km storm-relative helicity around 350 m2/s2
    suggesting an isolated tornado threat will also be possible. The
    severe threat may increase along the leading edge of the line, if it
    can become more surface-based.
