    Mesoscale Discussion 2038

    Areas affected...portions of northern Texas

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

    Valid 052322Z - 060115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...At least a few instances of severe wind or hail may
    accompany the stronger storms this evening, particularly with any
    supercells that can become established.

    DISCUSSION...Thunderstorms are intensifying near a surface frontal
    boundary draped zonally across northern TX (just north of the
    Metroplex). Ahead of these storms resides a buoyant airmass,
    characterized by steep mid-level lapse rates over a mixed boundary
    layer with 15-20 F temperature/dewpoint spreads. Furthermore,
    general veering with height is contributing to elongated and curved
    hodographs (albeit with some veer-back-veering within the profiles
    per RAP forecast soundings). With 40 kt effective bulk shear values
    overlapping with 1500-2500 J/kg MLCAPE ahead of ongoing storms,
    multicells and supercells are possible, accompanied by both a severe
    wind/hail risk. The ongoing storm over Denton County is currently
    exhibiting outflow tendencies per KFWS NEXRAD radar imagery, which
    will likely help drive the frontal boundary southward. As such, it
    is unclear how many storms will be able to cross to the warm side of
    the boundary. Overall, the complex mesoscale setup and undercutting
    boundaries suggest that the overall severe threat may remain
    isolated.
