    Mesoscale Discussion 1142

    Areas affected...portions of New Mexico and West Texas

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

    Valid 142019Z - 142215Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated to widely scattered thunderstorms will pose a
    risk for isolated damaging wind gusts and large hail through this
    evening. Watch issuance is unlikely.

    DISCUSSION...Latest visible satellite and regional radar imagery
    depict developing thunderstorms along higher terrain areas from
    western New Mexico into West Texas, with additional thunderstorms
    ongoing along a cold front west of Midland. In central New Mexico,
    dewpoints near 50 F and continued insolation are yielding weak
    buoyancy (500-1000 J/kg MLCAPE per the 18z ABQ sounding), with
    modified 18z EPZ/ABQ soundings suggesting lingering inhibition is
    eroding. As convection spreads eastward off of the high terrain,
    well-mixed boundary layer profiles (LCLs close to 3 km) and steep
    low-level lapse rates will support evaporatively-cooled downdrafts
    capable of isolated damaging wind gusts. Modestly strong upper-level
    flow associated with the subtropical jet stream is also supporting
    of 30-35+ kts, which will support some potential for isolated large
    hail when coupled with modestly steep mid-level lapse rates of
    around 7.5 C/km.=20

    Greater instability exists with southward extent into West Texas,
    with dewpoints increasing into the low-60s F ahead of a surface cold
    front. This is yielding a better overlap of buoyancy and shear
    across the southern portions of the discussion area, which may favor
    a marginally greater severe risk compared to areas farther north.
    Watch issuance appears unlikely at this time owing to the overall
    expectation for the severe risk to remain limited in
    coverage/magnitude.
