   Areas affected...southern South Dakota southward to eastern
   Colorado/northwestern Kansas

   Concerning...Severe Thunderstorm Watch 475...

   Valid 280116Z - 280315Z

   The severe weather threat for Severe Thunderstorm Watch 475
   continues.

   SUMMARY...Severe risk has diminished within WW 475 from far southern
   South Dakota southward, as existing/very isolated storms have
   decayed over the past hour.  Very limited severe risk persists,
   given potential for an additional storm or two, but no appreciable
   increase in coverage/risk is anticipated at this time.

   DISCUSSION...Latest radar loop shows the few isolated/strong to
   severe cells which were ongoing from from western Nebraska to
   eastern Colorado/northwestern Kansas have diminished/dissipated over
   the past hour.  A moist/unstable airmass persists east of the
   surface trough, but the boundary layer will continue to nocturnally
   cool, along with an associated increase in capping as depicted in
   the LBF 00Z RAOB.  As such, any additional storm development in the
   next couple of hours should remain very isolated at best.
