    Areas affected...Central New Mexico to far west Texas

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

    Valid 262153Z - 270000Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated to scattered thunderstorms developing across
    central New Mexico to far west Texas will pose an isolated large
    hail and severe wind risk through the early evening hours. Watch
    issuance is not expected.

    DISCUSSION...Thunderstorm development has been well underway across
    NM to far west TX, but recent GOES IR imagery and lightning trends
    have shown an uptick in intensity in a few cells. While not
    high-caliber by most measures, the environment across the region
    remains favorable for organized convection with 1000-1500 J/kg
    MLCAPE and effective shear values near 20 knots. This may support a
    few organized cells capable of posing a large hail risk. Dewpoint
    depressions across the region on the order of 40-50 F indicate that
    the boundary layer is fairly well mixed, and this is supported by
    0-3 km lapse rates around 8-9 C/km per latest mesoanalysis
    estimates. This low-level thermodynamic environment, combined with
    PWAT values below 1 inch, is conducive for downbursts and perhaps
    outrunning outflows that may lead to thunderstorm clustering. Both
    of these scenarios would pose a risk for strong to severe gusts
    through the early evening hours prior to sunset and on the onset of
    nocturnal cooling. However, given the overall marginal convective
    environment, watch issuance is not expected.
