    Mesoscale Discussion 2122
    NWS Storm Prediction Center Norman OK
    0425 PM CDT Sat Sep 09 2023

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

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

    Valid 092125Z - 092300Z

    Probability of Watch Issuance...5 percent

    SUMMARY...An isolated severe gust or instance of hail may accompany
    the stronger storms this afternoon. A WW issuance is not expected.

    DISCUSSION...Multicellular and pulse-cellular storms have been
    gradually intensifying over the higher terrain in central NM, where
    strong surface heating and boundary-layer mixing has boosted MLCAPE
    over 1000 J/kg. Given scant low-level moisture, these storms are
    high-based and are expected to remain so through the rest of the
    afternoon. 9+ C/km low-level lapse rates (per 21Z mesoanalysis)
    should support the potential for a severe gust or two. Given steep
    lapse rates also present in the 700-500 mb layer, some hail may also
    accompany the most potent storm cores. Nonetheless, the severe
    threat should remain isolated overall and a Severe Thunderstorm
    Watch issuance is not expected.
