   Areas affected...Western SD

   Concerning...Severe Thunderstorm Watch 360...

   Valid 140256Z - 140500Z

   The severe weather threat for Severe Thunderstorm Watch 360
   continues.

   SUMMARY...Isolated wind/hail threat will slowly shift east over the
   next few hours.

   DISCUSSION...Scattered high-based convection that developed over
   southeast WY has lifted north-northeast across western SD where
   low-level warm advection and buoyancy are a bit greater than across
   the higher Plains. 00z sounding from RAP was modestly unstable but
   notably capped around 1km AGL. This activity has been slow to shift
   east, possibly due to the CINH. However, heights will continue to
   fall across the northern High Plains tonight and this should nudge
   this corridor of convection northeast over the next few hours,
   possibly back into southern portions of ww358. Wind/hail remain
   possible with this activity.
