   Concerning...Severe Thunderstorm Watch 421...422...

   Valid 090451Z - 090615Z

   The severe weather threat for Severe Thunderstorm Watch 421, 422
   continues.

   SUMMARY...The threat for primarily damaging wind will continue into
   the overnight hours.

   DISCUSSION...At 0445Z, the longer-lived thunderstorm cluster that
   moved across southwest SD/northwest NE and the more recent intense
   development across central NE have consolidated into a loosely
   organized MCS that is moving into north-central NE/south-central SD.
   This MCS should continue to propagate northeastward into eastern
   SD/northeast NE, where MLCAPE is maximized (2500-4000 J/kg) and
   MLCINH is a relative minimum per recent mesoanalyses. 

   This system recently produced a 53 kt gust at KICR in south-central
   SD, and at least sporadic severe gusts should continue overnight
   given strong instability and presence of a relatively organized cold
   pool. There remains some potential for a corridor of more
   concentrated damaging wind, though the system may struggle to
   maintain organization given relatively weak low-level inflow and
   deep-layer shear and increasing MLCINH with time as the boundary
   layer continues to cool. Some hail cannot be entirely ruled out
   given the strong instability, though the increasingly linear storm
   mode should maintain damaging wind as the primary threat overnight.
