    Areas affected...western Oklahoma...far eastern Texas Panhandle and
    northwest Texas

    Concerning...Severe Thunderstorm Watch 194...

    Valid 092319Z - 100215Z

    The severe weather threat for Severe Thunderstorm Watch 194
    continues.

    SUMMARY...Large hail threat persists into western Oklahoma and
    northwest Texas. A few damaging gusts may develop anywhere within
    the watch.

    DISCUSSION...Several supercells currently extend from the eastern TX
    Panhandle into west-central OK, with reports from 1.50" to 2.01"
    diameter. These cells are interacting with the moisture/instability
    axis while the boundary layer remains near peak heating.

    Midlevel west/northwest winds of 40 kt atop backed/southeasterly
    surface winds are creating favorable shear profiles to support the
    hail cells, and the increasing low-level jet may enhance inflow and
    rightward motion later this evening before inhibition increases.

    Farther north, a line of high-based convection persists from central
    KS into the OK Panhandle, where dewpoints are only in the 30s and
    40s F. However, an increasing low-level jet this evening will bring
    50s F dewpoints northward into the area, possibly supporting a
    degree of strengthening along any existing outflow surge.
