    Mesoscale Discussion 0159

    Areas affected...Central and Eastern Kentucky...Northern Tennessee

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

    Valid 271142Z - 271415Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A threat for marginally severe hail may develop over parts
    of central and eastern Kentucky this morning. The magnitude of the
    hail threat should remain too small for weather watch issuance.

    DISCUSSION...The latest water vapor imagery shows a patch of
    maximized mid-level moisture associated with a shortwave trough,
    located across the Ohio and Tennessee Valleys. Scattered
    thunderstorms are ongoing with this area ahead of the shortwave
    trough over far southern Indiana, central Kentucky and middle
    Tennessee. Mesoscale analysis in central Kentucky has MUCAPE
    approaching 1000 J/kg, with 700-500 mb lapse rates in the 7 to 7.5
    C/km range. In addition, RAP forecast soundings in central Kentucky
    have a steep temperature inversion from the surface to 850 mb, with
    effective shear near 50 knots. This suggests some potential for a
    couple elevated rotating storms capable of marginally severe hail.
    The threat should continue into the mid to late morning as scattered
    strong thunderstorms move eastward into eastern Kentucky.
