    Areas affected...south-central and southeast KS into northern and
    central OK

    Concerning...Severe Thunderstorm Watch 314...

    Valid 240647Z - 240815Z

    The severe weather threat for Severe Thunderstorm Watch 314
    continues.

    SUMMARY...Isolated large hail is possible with thunderstorm clusters
    across Oklahoma into southeast Kansas and southwest Missouri. A
    greater damaging wind risk may develop over the next couple hours as
    an organizing cluster moves southeast across south-central KS into
    northern OK.

    DISCUSSION...Thunderstorm clusters are ongoing early this morning
    across portions of central into northeast OK, southeast KS and
    southwest MO within a warm advection regime atop an EML between
    850-700 mb. This activity may sporadically intensify and produce
    hail up to 1.25 inch diameter given 7.5-8.5 C/km midlevel lapse
    rates and strong MUCAPE. While effective shear is quite good,
    updrafts are likely not taking full advantage of favorable low-level
    shear typically conducive for supercell development, tempering the
    overall risk with these thunderstorm clusters.=20

    Upstream across southwest KS, and within Severe Thunderstorm Watch
    314, an organizing cluster of storms will continue to shift
    east/southeast toward south-central KS/north-central OK over the
    next few hours. This activity will track along the theta-e/MUCAPE
    instability gradient, and on the nose of a 30-40 kt low-level jet.
    While radar trends have shown outflow just ahead of this cluster,
    there is some potential new updrafts could develop along the
    outflow, or convection could ingest the outflow as the bowing
    cluster continues to organize and intensify as it tracks into better instability/low-level moisture with southeast extent. Depending on
    short-term trends, a new watch may be needed downstream of WW 314
    across portions of northern OK/southeast KS and vicinity.
