   Mesoscale Discussion 0917
   NWS Storm Prediction Center Norman OK
   1150 PM CDT Thu Jun 10 2021

   Areas affected...Western into central SD

   Concerning...Severe Thunderstorm Watch 253...

   Valid 110450Z - 110615Z

   The severe weather threat for Severe Thunderstorm Watch 253
   continues.

   SUMMARY...A swath of significant severe wind appears increasingly
   likely through 06Z.

   DISCUSSION...A 78 mph wind gust was recently reported across
   northwest SD, and a 72 mph gust with storms across southwest SD. In
   addition, a cluster moving over the KUDX radar was producing 70-80
   kt radar velocities at very low elevation above ground. With
   additional strong updrafts noted across west-central SD, and a cold
   front accelerating into the region, the potential for a swath of
   significant severe wind should increase over the next 1-2 hours as
   outflows continue to consolidate and stronger low-level flow near
   and behind the cold front begins to catch up with ongoing
   convection, within an environment of strong buoyancy and effective
   shear.
