    Areas affected...Northeast NM into the western TX/OK Panhandles

    Concerning...Severe potential...Watch likely=20

    Valid 252331Z - 260100Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Some increase in storm coverage and intensity is possible
    this evening, with a threat for hail and localized severe gusts.
    Watch issuance is likely.

    DISCUSSION...At 2315 UTC, a thunderstorm cluster over southeast CO
    is approaching the far western TX/OK Panhandles, with other storms
    intensifying farther southwest toward the Raton Mesa. Modest
    destabilization (MLCAPE of 1000-1500 J/kg) has occurred downstream,
    with some towering cumulus noted to the west and northwest of
    Tucumcari. With recent observations suggesting the presence of a
    modest cold pool associated with the southeast CO storm cluster, and
    some increase in a southeasterly low-level jet expected with time,
    an increase in storm coverage is expected this evening into extreme
    northeast NM and the western TX/OK Panhandles.=20

    Midlevel flow is not particularly strong, but a favorably veered
    wind profile is supporting effective shear of 30-40 kt, with a
    tendency toward somewhat greater shear values with southward extent.
    The ongoing storm cluster may become better organized as it
    continues to move southeastward, with a threat for a couple
    supercells along its southwestward flank. If a small MCS can become
    better organized, the threat for isolated to scattered severe gusts
    will increase this evening. Otherwise, any sustained supercells will
    pose a threat for hail, localized severe gusts, and possibly a brief
    tornado.
