    Areas affected...portions of far eastern New Mexico...the Texas and
    Oklahoma Panhandles...into far southwestern Kansas

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

    Valid 092122Z - 092315Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated to widely scattered high-based convection may
    pose a risk for a strong to severe gust this evening. Severe
    coverage should be low and a WW is not anticipated.

    DISCUSSION...As of 2120 UTC, regional radar and visible imagery
    showed isolated to widely scattered high-based convection developing
    along a surface pressure trough/weak dryline over portions of the
    southern High Plains. Ample diurnal heating has steepened low-level
    lapse rates sufficient for weak destabilization amid limited
    boundary-layer moisture (30s and 40s F surface dewpoints). This is
    promoting deep inverted-v thermodynamic profiles beneath the
    buoyancy. Deep-layer shear is weak (generally less than 20 kt)
    suggesting storm organization and longevity will be rather limited.
    However, the dry sub-cloud layer and steep low-level lapse rates may
    promote strong downdraft accelerations. Sporadic severe gusts (55-70
    mph range) are possible associated with dry microbursts in the
    stronger cores that can develop. Given the relatively limited
    spatial and temporal risk, a WW is unlikely.
