   The severe weather threat for Severe Thunderstorm Watch 331
   continues.

   SUMMARY...The threat for severe hail and wind will continue for the
   near term, but a gradual weakening trend is likely after the 02-03
   UTC time frame.

   DISCUSSION...Thunderstorms that have developed along an outflow
   boundary from northeast SD into southeast ND will continue to pose
   the risk for severe hail, and perhaps severe winds, with any
   stronger updraft pulses. Augmented low-level vorticity along the
   boundary coupled with relatively long storm residence times will
   continue to support the potential for a few funnel clouds and
   perhaps a brief tornado - though the overall tornado potential
   remains low. With time, storm interactions and undercutting outflows
   should act to gradually diminish storm intensity. 

   The line of storms moving into southeast SD should continue to pose
   the threat for strong to severe winds for the next hour or so, but
   IR imagery trends show warming cloud tops suggesting a gradual
   weakening of the line. As this line continues east it will move into
   a weaker shear environment with less-favorable low-level lapse rates
   for supporting strong outflows.
