    Areas affected...portions of the southern High Plains

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

    Valid 021749Z - 022015Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered to numerous thunderstorms will bring a risk for
    damaging wind gusts and large hail to portions of the southern High
    Plains through this evening. Watch issuance is unlikely.

    DISCUSSION...Latest radar/satellite imagery depicts developing
    thunderstorms along the higher-terrain areas of central/southeastern
    New Mexico, with additional development expected farther south into
    West Texas by early afternoon. Continued insolation amid moist
    southeasterly, low-level flow is expected to support 1000 to locally
    2000 J/kg MLCAPE by peak heating this afternoon. RAP forecast
    soundings suggest convection moving off of the high-terrain will
    initially encounter increasingly deep boundary layers owing to
    diurnal mixing, with latest guidance suggesting surface dewpoint
    depressions may exceed 40 F by the mid-to-late afternoon. Weak
    effective shear across the region (generally less than 20 kts per
    latest mesoanalysis) and inverted-V thermodynamic profiles will
    promote efficient evaporative cooling and outflow-dominant storm
    structure, with the potential for damaging wind gusts. Isolated
    large hail may also accompany the most robust updrafts owing to
    steep mid-level lapse rates.

    Farther north across northeastern New Mexico, latest surface
    analysis depicts a roughly west-east oriented outflow boundary
    extending from the northern Texas Panhandle towards the high terrain
    of north-central New Mexico, with two discrete supercells noted in
    this region north of I-40 via recent radar imagery. Objective
    analysis depicts a corridor of locally greater buoyancy (2000+ J/kg
    MLCAPE) and marginally enhanced effective shear (25-35 kts) along
    and south of this boundary. This is likely to favor area of locally
    greater large hail potential through this afternoon. A brief
    tornado/landspout also cannot be ruled out should a storm interact
    with the greater low-level shear/surface vertical vorticity analyzed
    along this boundary.

    Given the expectation for storm organization and severe magnitude to
    remain largely limited, watch issuance appears unlikely at this
    time. Trends will continue to be monitored, however.
