    Areas affected...Parts of central/northeast OK...southeast KS...and
    southwest MO

    Concerning...Severe Thunderstorm Watch 314...316...

    Valid 112256Z - 120030Z

    The severe weather threat for Severe Thunderstorm Watch 314, 316
    continues.

    SUMMARY...Risk of large hail and damaging winds spreading eastward
    across central/northeastern Oklahoma and southeast Kansas -- within
    Severe Thunderstorm Watches 314 and 316.

    DISCUSSION...Semi-discrete supercell structures are evolving
    eastward along a northeast/southwest-oriented cold front extending
    from southeast KS across northeast/central OK. Along this segment of
    the cold front, around 30 kt of deep-layer shear (per VWP data) and
    storm motions directed off the boundary should continue to promote semi-discrete supercell structures with a risk of large hail and
    damaging winds in the near term. With time, an increasingly parallel
    component of the deep-layer flow/shear to the front and
    strengthening cold pools should favor upscale growth into a line of
    storms, which will promote more of a damaging wind risk.
