    Mesoscale Discussion 1405

    Areas affected...portions of eastern New Mexico into western Texas

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

    Valid 221950Z - 222115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The risk for a few instances of severe wind/hail will
    increase through the afternoon. The severe threat should be isolated
    enough to preclude a WW issuance.

    DISCUSSION...Thunderstorms have recently shown an uptick in
    intensity across portions of central NM into the TX Trans Pecos,
    with a cell in Lincoln County, NM showing 40 dBZ echoes at 50 kft.
    MLCINH is eroding due to strong diurnal heating, which is promoting
    robust boundary-layer mixing, with 0-3 km lapse rates already
    approaching the 9-10 C/km range in spots (per 19Z mesoanalysis).
    Additional storms should continue to develop and intensify this
    afternoon given persistent diurnal heating, with MLCAPE likely
    exceeding 1000 J/kg. Vertical shear will be weak, and given marginal
    MLCAPE, most storms should be pulse cellular or weakly
    multicellular. Given steep low-level lapse rates, rapid evaporative
    cooling with stronger storm cores may result in severe gusts and
    perhaps a brief instance of hail. Since the severe threat should be
    isolated, a WW issuance is not expected.
