    Concerning...Severe Thunderstorm Watch 495...

    Valid 080344Z - 080515Z

    The severe weather threat for Severe Thunderstorm Watch 495
    continues.

    SUMMARY...The threat for isolated damaging gusts may spread a little
    southeast of the current watch. The need for a downstream watch
    into Missouri is uncertain.

    DISCUSSION...A cluster of storms has evolved into a somewhat
    organized/bowing segment that has recently produced measured gusts
    up to 67 mph in the Omaha area. Local radar images suggest that
    convective outflow is several miles ahead of the primary convective
    cores, with a 40-50 kt rear inflow signature. The orientation of
    the low-level shear vectors ahead of the convection suggests that an
    anafrontal configuration should be maintained with very gradual
    weakening of the storms over time. However, there is still
    potential for isolated damaging/severe outflow gusts which could
    spread a couple of counties southeast of the current watch
    configuration. Given the expectation for gradual weakening
    overnight, the need for a new/downstream watch into MO is somewhat
    uncertain.
