   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.
