   Mesoscale Discussion 0954
   NWS Storm Prediction Center Norman OK
   1121 PM CDT Sat May 28 2022

   Areas affected...South-Central SD

   Concerning...Severe Thunderstorm Watch 284...

   Valid 290421Z - 290545Z

   The severe weather threat for Severe Thunderstorm Watch 284
   continues.

   SUMMARY...Gusty winds remain possible with convection.

   DISCUSSION...Very weak short-wave trough is ejecting northeast
   across the Dakotas late this evening. The southern-most influence of
   this feature appears to be aiding convection across south-central
   SD, along with a 25-50kt LLJ that extends across central NE into
   this cluster. This activity does not appear to be particularly
   robust, but 44kt wind gust was observed in the last 30 minutes at
   KICR. Gusty winds may continue to be noted ahead of this cluster as
   it spreads northeast.
