    Areas affected...portions of southwestern Oklahoma into southeastern
    Kansas and southwestern Missouri

    Concerning...Severe Thunderstorm Watch 93...

    Valid 040131Z - 040300Z

    The severe weather threat for Severe Thunderstorm Watch 93
    continues.

    SUMMARY...Several discrete/semi-discrete supercells continue to pose
    a threat for large/very large hail, damaging wind gusts, and a
    tornado or two, with the greatest potential across portions of
    central Oklahoma.

    DISCUSSION...Discrete/semi-discrete supercells have persisted across
    portions of southwestern/central Oklahoma over the past 1-2 hours,
    with several instances of 2+ inch hail reported across Kiowa County,
    Oklahoma. These storms will continue to pose a threat for large/very
    large hail and severe wind gusts across portions of WW93 over the
    next couple of hours. The greatest risk for severe, including the
    potential for a brief tornado or two, will likely be across portions
    of central Oklahoma, where backing surface winds and increasingly
    curved low-level hodographs (~200 m2/s2 0-500 m SRH) have been noted
    over the past 30-60 minutes per the OUN VWP. Farther northeast,
    convection across southeastern Kansas/northeastern Oklahoma,
    convection has shown some signs of weakening, but at least some
    potential for severe hail continues to linger with more intense
    cores.

    Upscale growth into a more linear storm mode is still expected along
    the cold front with time, which will bring a transition toward
    severe wind gusts as the primary threat. It remains uncertain
    whether a local extension in time of WW93 or a new Severe
    Thunderstorm Watch may be needed to cover the lingering severe risk
    this evening and perhaps into the overnight.
