   Concerning...Severe Thunderstorm Watch 428...

   The severe weather threat for Severe Thunderstorm Watch 428
   continues.

   SUMMARY...Severe-weather potential -- mainly in the form of damaging
   winds -- continues across western portions of WW 428.

   DISCUSSION...Latest radar loop shows a well-organized, bowing MCS
   crossing the western border region of North Dakota/South Dakota at
   this time.  The storms are being fueled by 1000 to 2000 J/kg
   mixed-layer CAPE, in an axis extending from southeastern Montana
   eastward/northeastward.  With southeasterly low-level flow indicated
   across this region, forward propagation of this convective band is
   expected, given the available/downstream CAPE.  Damaging wind gusts
   can be expected locally, with a couple of low-60s MPH gusts recorded
   over the past hour with this convection.  A few instances of
   marginally severe hail may also occur, as the storms advance
   eastward.
