    Areas affected...North-central Texas...Far Southern Oklahoma

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

    Valid 190801Z - 191030Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated threat for large hail and severe wind gusts
    will likely continue across north-central Texas over the next few
    hours, and could impact far southern Oklahoma as well. The threat is
    expected to remain too marginal for watch issuance.

    DISCUSSION...Latest surface analysis shows a quasi-stationary front
    located from west-central Texas northeastward into southeast
    Oklahoma. Nearly surface-based thunderstorms are developing close to
    the boundary to the south-southwest of Wichita Falls. The storms are
    located just to the north of a pocket of strong instability, where
    surface dewpoints are in the upper 70s F and the RAP has MLCAPE in
    the 4000 to 5000 J/kg range. In addition, RAP forecast soundings
    over north-central Texas have 700-500 mb lapse rates near 8 C/km.
    This thermodynamic environment will be favorable for an isolated
    large hail and a wind-damage threat. Although deep-layer shear is
    weak over much of north-central Texas, RAP forecast soundings a bit
    further east have 0-6 km shear in the 20 to 25 knot range. As the
    storms move eastward into a slightly more favorable environment, the
    severe threat is expected to be maintained or could increase some.
    However, large-scale ascent is limited over central and north Texas,
    which may keep any severe threat localized.
