    Mesoscale Discussion 0292

    Areas affected...southwest Kansas across the eastern Oklahoma and
    Texas Panhandles...western Oklahoma and northwest Texas

    Concerning...Severe potential...Watch likely=20

    Valid 241903Z - 242100Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Scattered storms are likely to form along a dryline this
    afternoon, and several may become severe. The primary risk will be
    from large hail, though locally damaging gusts or a brief tornado
    will also be possible.

    DISCUSSION...Visible imagery shows substantial high-based convection
    forming near and behind the dryline, which currently extends from
    far southwest KS across the TX Panhandle and South Plains. This area
    is within a deep-layer steep lapse rate plume.=20

    Ahead of the dryline, clearing and heating are occurring, which will
    help destabilize the air mass. However, moisture is currently
    limited with only 40s to lower 50s F dewpoints in general.

    As the dryline continues to move rapidly east, a north-south broken
    line of storms is forecast to form, with a few robust cells
    producing hail. The instability axis is forecast to remain
    relatively narrow, especially near the OK/TX portion of the dryline
    initially. With time, moisture advection may result in a more
    favorable area for supercells later today/evening into northwest TX,
    as surface observations indicate increasing dewpoints. The strong
    deep-layer shear combined with steep lapse rates will favor hail
    across the entire area, with any brief tornado threat limited to the
    narrow uncapped area along the dryline. Given the strong flow aloft
    over OK and TX, storms may move off the dryline rather quickly,
    perhaps becoming elevated farther east. However, somewhat weaker
    flow over KS, as well as a wider warm sector, could sustain a
    supercell or two with hail and brief tornado risk over a relatively
    wider area.
