    Areas affected...Permian Basin into Texas South Plains

    Concerning...Severe potential...Watch possible=20

    Valid 232339Z - 240045Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Large to conditionally very-large hail and isolated severe
    gusts will be the main hazards with scattered storms this evening. A
    severe thunderstorm watch is possible depending on convective
    intensity trends.

    DISCUSSION...Regional radar imagery is showing the initial stages of
    discrete storm development within parts of the Permian Basin into
    the Texas South Plains. A band of cirrus within the southern Plains
    is indicative of lift associated with an upper trough that will be
    digging into the region over the next several hours. That cloud
    cover has limited surface based instability, though greater MLCAPE
    is noted farther east into the Rolling Plains. Strong mid-level
    winds are promoting 45-55 kts of 0-6 km shear. At least some storm
    organization can be expected. Large to potentially very large hail
    could occur as mid-level lapse rates are rather steep (per 18Z MAF
    sounding). Dry low levels will tend to mitigate some storm
    intensity, however. Isolated severe wind gusts are also possible. A
    brief tornado could also occur given southeasterly surface winds and
    an increasing low-level jet this evening. A severe thunderstorm
    watch is possible this evening. Storm intensity is somewhat
    uncertain, but coverage may be scattered. The overall scenario may
    be that a few more intense storms develop, but storm interaction
    keeps the duration of these storms limited. Trends will be
    monitored.
