    Areas affected...north-central Texas

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

    Valid 090029Z - 090230Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Thunderstorm activity will move southward across the Red
    River into north-central Texas this evening. Additional thunderstorm development will be possible south of the Red River north of the DFW
    Metro.

    DISCUSSION...A broken line of thunderstorms continues to move south
    and east across portions of central Oklahoma. This is tending to
    cluster along outflow but embedded supercells are still producing
    occasional hail up to 1.75-2.75 inches. Through time, this will
    continue to evolve into a greater damaging wind threat as it moves
    into north Texas this evening given trends in growth along outflow. Temperatures downstream are cooling, with temperatures in the mid to
    upper 70s. The 00z sounding from FWD shows less favorable low levels
    but does show a deep layer of instability aloft. Upper level flow
    remains modest but downward momentum transport from heavier cores
    may produce severe caliber winds. A watch will likely be needed
    downstream of WW192 soon.
