    Mesoscale Discussion 0631
    NWS Storm Prediction Center Norman OK

    Areas affected...Parts of south-central TX

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

    Valid 010600Z - 010830Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A threat for isolated hail and damaging gusts will
    continue overnight.

    DISCUSSION...Strong thunderstorms are ongoing across parts of
    south-central TX as of 06 UTC, with occasional elevated supercells
    noted. This activity continues to develop north of a nearly
    stationary surface front, and may persist through much of the
    overnight as a mid/upper-level shortwave trough approaches the
    region from northern Mexico.=20

    While midlevel lapse rates (as observed in the 00Z CRP sounding and
    analyzed by the RAP) are not particularly steep, rich moisture above
    the frontal inversion is supporting MUCAPE of 500-1500 J/kg where
    storms are ongoing. Strong mid/upper-level westerly flow is
    resulting in effective shear of 60+ kt, more than sufficient for
    organized convection. Large hail and localized damaging gusts will
    continue to be possible with the strongest storms overnight. A
    recent elevated storm with hail near Houston suggests that some
    severe potential may extend farther north than analyzed MUCAPE would
    indicate, though storms that track farther south (closer to the
    front) will have access to stronger buoyancy, and perhaps a
    localized very large hail threat.
