    Areas affected...portions of western and central OK into north TX

    Concerning...Severe Thunderstorm Watch 463...

    Valid 090838Z - 091015Z

    The severe weather threat for Severe Thunderstorm Watch 463
    continues.

    SUMMARY...Gusts to 70 mph and isolated hail to 2 inches possible the
    next 1-2 hours across WW 463.

    DISCUSSION...A well organized bowing segment is tracking across
    southwest OK early this morning at around 50 kt. Several gusts to 70
    mph have been measured over the past 1-2 hours. This bow will
    continue to move across an area characterized by 1500-2000 J/kg
    MUCAPE and 35+ kt effective shear magnitudes. Boundary-layer
    inhibition increases markedly south of the Red River. However, a
    75-85 kt rear inflow jet, as sampled by KFDR, will likely maintain
    severe gust potential the next couple of hours as the bow approaches
    the Red River. A moist and unstable airmass is in place across north
    Texas, and severe gust potential may persist outside of WW 463.=20

    Additional more isolated/semi-discrete supercells are developing in
    a band from the OKC Metro east/southeast toward southeast OK in warm
    advection ahead of the advancing bow. These supercells may continue
    to pose a risk for strong/severe gusts and large hail around 1-2 in
    diameter.

    A new severe thunderstorm watch may be needed soon downstream into south-central/southeast OK and north Texas.
