    Areas affected...Eastern New Mexico

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

    Valid 051928Z - 052130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Storm coverage expected to increase this afternoon, a few
    of which may produce severe hail/wind gusts, though watch issuance
    is unlikely.

    DISCUSSION...Visible satellite trends show a decrease in cloud cover
    throughout the late morning/early afternoon across most of eastern
    New Mexico, while strong heating has been occurring along/near the
    Sangre de Cristo Mountains. Surface observations show easterly
    upslope flow into region, with dew point temperatures in the upper
    50s and lower 60s. This combination is yielding MLCAPE of 1000-1500
    J/kg, with isolated storms beginning to develop in proximity to the
    Sangre de Cristo range.

    Storm coverage should continue to increase, particularly in
    northeast New Mexico, as continued heating/destabilization occurs,
    with multicells emerging as the predominant mode. Deep-layer shear
    is notably weak across the state, approaching 30-35 kt with northern
    extent. Therefore, a few storms may organize into supercell
    structures, at least briefly, with the potential for severe
    hail/wind gusts. With time, storm coverage should expand southward,
    though coverage of the severe threat is anticipated to remain low.
    Given these expectations, watch issuance is unlikely for the region
    at this time.
