    Mesoscale Discussion 0811

    1106 AM CDT Fri May 16 2025

    Areas affected...south-central Kentucky into parts of northern
    Tennessee

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

    Valid 161606Z - 161830Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered severe storms may persist in the near term west
    of the WW 261. Hail and locally strong gusts are most likely.

    DISCUSSION...Episodes of storms continue to move eastward across KY
    and northern TN within the low-level warm advection regime, and atop
    existing outflows. Instability continues to strengthen over TN, and southwesterly winds will maintain the unstable air into the existing
    zone of storms/outflows. In the near term, the stronger storms in
    the existing line may produce hail or locally strong gusts before
    moving into WW 261 to the east. There is some chance that the
    increasing instability supports a tail-end cell producing damaging
    hail, and/or a cell may form ahead of the line.
