    Areas affected...south-central Nebraska into adjacent north-central
    Kansas

    Concerning...Severe Thunderstorm Watch 136...

    Valid 260506Z - 260600Z

    The severe weather threat for Severe Thunderstorm Watch 136
    continues.

    SUMMARY...Severe risk diminishing across the WW area.

    DISCUSSION...Latest radar loop shows widespread, ongoing
    thunderstorms across much of southern and eastern Nebraska, with weaker/scattered -- but increasing -- convection across Kansas
    northeast of the well-defined baroclinic zone. Persistent low-level
    warm advection -- associated with a 50-plus kt southerly low-level
    jet -- will continue to support convection overnight, given abundant
    elevated instability.

    With that said, severe risk continues to decrease. The strongest
    storms -- organizing into a bowing MCS -- are moving across eastern
    Nebraska at this time, elevated atop a 1500m deep stable layer. As
    such, severe risk appears limited with these storms.

    Elsewhere, convection has weakened considerably over the past hour,
    and expect largely sub-severe storms to prevail the remainder of the
    overnight period. Presuming trends continue to support this
    scenario, WW 136 will likely be able to be cancelled prior to its
    26/07Z expiration.
