   Areas affected...central and eastern South Dakota...southwest
   Minnesota

   Concerning...Severe Thunderstorm Watch 461...

   Valid 280430Z - 280630Z

   The severe weather threat for Severe Thunderstorm Watch 461
   continues.

   SUMMARY...Dangerous wind gusts in excess of 80 mph are possible in
   association with an MCS taking shape over central South Dakota.

   DISCUSSION...Storms are rapidly evolving into a focused MCS over
   central SD, now approaching the Pierre area. Several gusts over 80
   mph have been measured recently, and this threat is likely to
   continue spreading east as the storms move into an unstable
   environment. Strong deep-layer shear and a southwesterly low-level
   jet tonight will aid MCS longevity, with damaging winds expected to
   persist across the state of SD and eventually southwest MN.
