    Mesoscale Discussion 2168

    Areas affected...Texas Panhandle and western Oklahoma

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

    Valid 241804Z - 242030Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Scattered thunderstorms are developing across the region,
    a few of which may eventually pose a risk for severe hail/wind.
    Watch issuance is possible.

    DISCUSSION...Regional satellite shows an expansive area of cloud
    cover overspreading the region, limiting insolation, with some
    pockets of clear skies remaining. This, along with low-level
    warm-air advection, has allowed surface temperatures to warm into
    the upper 60s F to near 70 F, amid seasonally rich low-level
    moisture, characterized by surface dew point temperatures in the low
    60s F. Broad ascent associated with an approaching mid-level trough
    and cooling temperatures aloft, in combination with the
    aforementioned low-level thermodynamics, is resulting in
    destabilization across the region, with MLCAPE approaching 1000-1500
    J/kg. Consequently, deepening convection is beginning to take shape,
    with a few more robust cells evident in regional radar.

    These trends are expected to continue into the early afternoon,
    perhaps eventually yielding MLCAPE near 2000 J/kg, particularly in
    areas closer to the approaching upper trough across portions of the
    Texas Panhandle. Effective bulk shear near 40 kt should promote at
    least some storm organization, with severe hail/wind possible with
    the strongest cells. However, coverage of severe storms remains
    quite uncertain at the present time. Thus, convective trends will
    continue to be monitored for the possibility of watch issuance this
    afternoon.
