    Mesoscale Discussion 1419

    Areas affected...portions of southeastern New Mexico into far west
    Texas

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

    Valid 232018Z - 232045Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A severe gust or two cannot be ruled out this afternoon.
    The sparse severe threat should preclude a Severe Thunderstorm Watch
    issuance.

    DISCUSSION...MRMS mosaic radar imagery depicts intensifying
    thunderstorm updrafts, with 40 dBZ cores reaching the 30-50 kft
    range. Boundary layer lapse rates continue to steepen to 9 C/km (per
    20Z mesoanalysis) given strong surface heating. As such, one of the
    stronger storm cores could collapse and produce a severe gust.
    However, vertical wind shear is weak, and pulse-cellular storms
    should remain the primary storm mode. As such, the severe threat is
    low, and a WW issuance is not expected.
