    Areas affected...I-70 corridor from northern Kansas into northwest
    Missouri

    Concerning...Severe Thunderstorm Watch 154...

    Valid 270639Z - 270815Z

    The severe weather threat for Severe Thunderstorm Watch 154
    continues.

    SUMMARY...Elevated supercells will continue to pose a large hail and
    isolated damaging wind threat while spreading eastward along the
    I-70 corridor.

    DISCUSSION...Clusters of elevated supercells, with a recent history
    of hail up to 2 inches in diameter, continue to spread eastward
    along the I-70 corridor in north central and northeast KS. This
    area is within the left-exit region of a 100 kt jet at 300 mb, and
    along the north edge of the steep midlevel lapse rates where strong
    low-level warm advection is ongoing. The updrafts appear to be
    rooted near 850 mb with MUCAPE near 3000 J/kg. The combination of
    large buoyancy and strong cloud-layer/effective shear will continue
    to favor supercells capable of producing very large hail (near or
    above 2 inches in diameter). These storms will also be capable of
    producing isolated wind damage given the steep midlevel lapse rates
    and moderately large DCAPE.
