    Mesoscale Discussion 0316
    NWS Storm Prediction Center Norman OK
    0310 PM CDT Wed May 02 2018

    Areas affected...portions of the Concho Valley/Edwards Plateau

    Concerning...Severe potential...Severe Thunderstorm Watch likely

    Valid 022010Z - 022215Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Isolated storms developing near the dryline over western
    portions of Texas may require WW issuance to cover evolving
    hail/wind risk.

    DISCUSSION...Latest surface analysis shows a dryline mixing eastward
    into the Edwards Plateau/Concho Valley of Texas this afternoon, with
    a moist/moderately unstable airmass (mixed-layer CAPE in excess of
    2500 to 3000 J/kg) ahead of the dryline.

    Isolated storms have begun to develop near the dryline, with the
    strongest storm -- likely producing marginal hail -- now over
    Terrell County. Coverage of storms should remain isolated
    initially, but will likely increase gradually with time over the
    next few hours. With 50-plus kt mid-level southwesterly flow
    contributing to sufficient shear for organized/rotating storms,
    degree of large hail/damaging wind risk may require WW issuance.
