    Mesoscale Discussion 0848
    NWS Storm Prediction Center Norman OK
    0833 PM CDT Sat Jun 23 2018

    Areas affected...TX Big Country

    Concerning...Severe potential...Watch unlikely

    Valid 240133Z - 240330Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Large hail and strong/damaging wind gusts will be the
    primary severe-weather hazards with the remains severe storms that
    occur across the Texas Big Country until about 10 PM CDT.

    DISCUSSION...Trends in mosaic radar imagery indicated a few
    robust/sustained severe storms remained located across the TX Big
    Country this evening. Objective analyses showed these storms were
    located within an axis of very strong instability (MLCAPE 2000-3000
    J/kg) and effective bulk shear of 30-40 kt. Forcing for ascent
    attendant to a weak midlevel, eastward-moving, impulse will support
    additional strong to severe storms in the short term with favorable
    CAPE/shear parameter space resulting in hail and strong/damaging
    wind gusts as the main severe threats. The overall severe risks
    should diminish by 03Z as the onset of surface cooling stabilizes
    the boundary layer, rapidly increasing inhibition.
