   0400 AM CDT Sun Jun 11 2017

   Areas affected...east-central SD into southwest MN

   Concerning...Severe Thunderstorm Watch 311...

   Valid 110900Z - 111000Z

   The severe weather threat for Severe Thunderstorm Watch 311
   continues.

   SUMMARY...A corridor of scattered to widespread gusts ranging from
   50-75 mph are possible as the storm mode evolves from cellular to
   bow/line segment over the next 1-2.5 hours.

   DISCUSSION...Radar mosaic shows a congealing cluster of
   intense/severe thunderstorms from near Huron southwest into Buffalo
   County as of 09Z.  A couple of storms have developed in the warm
   advection wing to the east of the severe cluster during the past
   hour concurrent with a merging of thunderstorms cores on southwest
   flank of the lead cellular storm.  The continued upscale growth into
   a severe bow/line segment is likely over the next 1-2.5 hours to the
   north of a warm front draped over far southeastern SD into the
   southern tier of counties in southern MN.  As a result, it appears
   increasingly likely a concentrated area to the east of the
   thunderstorm complex (Miner/Kingsbury counties east into Lincoln
   county MN) will have increased potential for scattered to widespread
   50-75 mph gusts.
