    Areas affected...southeast Kansas...southwest Missouri...and far
    northeast Oklahoma

    Concerning...Severe Thunderstorm Watch 478...

    Valid 292037Z - 292200Z

    The severe weather threat for Severe Thunderstorm Watch 478
    continues.

    SUMMARY...Thunderstorms will continue through the afternoon.
    Isolated wind damage should be the primary threat.

    DISCUSSION...Thunderstorms continue to develop/loosely organize
    across southeast Kansas and southwest Missouri this afternoon along
    the leading edge of an advancing cold pool from overnight
    convection. The airmass along and ahead of these storms is strongly
    to extremely unstable, with MUCAPE values in excess of 5000 J/kg
    across northeast Oklahoma and northwest Arkansas, with very little
    convective inhibition remaining.=20

    The degree of instability and loose organization should continue a
    severe threat through the afternoon despite the presence of meager
    deep-layer shear. The extreme instability, and precipitable water
    values near 2 inches in the vicinity of these thunderstorms should
    lead to continued water-loaded downdrafts and a reinforcement of the
    cold pool, leading to continued thunderstorm development. An
    isolated severe wind gust or wind damage will be possible this
    afternoon, especially on or near area lakes where frictional effects
    will be minimized.
