    Areas affected...parts of southwest OK and western north TX

    Concerning...Severe Thunderstorm Watch 15...

    Valid 022145Z - 022315Z

    The severe weather threat for Severe Thunderstorm Watch 15
    continues.

    SUMMARY...Some threat for isolated hail, strong gusts, and possibly
    a tornado will continue through late afternoon.

    DISCUSSION...An arc of thunderstorms is ongoing late this afternoon
    from southwest OK into western north TX, immediately in advance of a
    compact cyclone moving across the TX Panhandle and South Plains.
    Earlier small supercells have evolved into a more disorganized
    linear structure, and limited buoyancy (with MLCAPE generally 500
    J/kg or less) may continue to limit the magnitude of the severe
    threat. However, low-level and deep-layer shear remain supportive of
    organized convection, and redevelopment of a small supercell or two
    and/or small bowing segments remain possible as the compact cyclone
    moves across the region through the late afternoon.

    Despite the meager buoyancy, cold temperatures aloft will support an
    isolated hail threat with the strongest cells. Localized strong to
    severe gusts will also be possible, especially if any small bowing
    segments can materialize, or if storms can develop farther south
    into a somewhat warmer and more unstable airmass across western
    north TX. A tornado also cannot be ruled out, if a supercell can
    favorably interact with low-level vorticity near a baroclinic zone
    located near and just south of the Red River.=20

    Stronger convection may eventually spread eastward into a larger
    portion of southwest OK and western north TX. While instability will
    generally weaken with eastward extent, strong ascent and favorable
    deep-layer shear may continue to support occasionally organized
    convection through late afternoon into the early evening.
