    Areas affected...Northeast KS into central MO

    Concerning...Severe Thunderstorm Watch 504...

    Valid 172240Z - 180015Z

    The severe weather threat for Severe Thunderstorm Watch 504
    continues.

    SUMMARY...Isolated severe storms remain possible into early evening,
    with a threat of hail and locally damaging gusts.

    DISCUSSION...In the wake of an earlier storm cluster that is now
    over southern MO and northern AR, storms have continued to redevelop
    near a surface boundary draped just south of the I-70 corridor from
    extreme northeast KS into central MO, where strong instability and
    moderate deep-layer shear are in place. With outflow approaching
    from the south and southwest impinging on the instability axis, the
    zone of potential redevelopment is becoming increasingly narrow, but
    an additional supercell or two may redevelop with a threat of large
    hail and locally damaging gusts.=20

    It is possible that an isolated storm or two may develop as far west
    as northeast KS, to the west of WW 504, but with coverage expected
    to remain quite isolated in this area, additional watch issuance is
    considered unlikely at this time. Local watch expansion may be
    considered if any notable development occurs north of WW 504.
