   The severe weather threat for Severe Thunderstorm Watch 608
   continues.

   SUMMARY...Severe threat continues within WW608.

   DISCUSSION...Two clusters of thunderstorms are ongoing across
   portions of southeastern Montana and northeastern Wyoming. Storms
   have produced severe gusts up to 68 mph and hail up to 1 inch in the
   last couple of hours. The greatest near term threat appears to be
   across northeastern Wyoming into western South Dakota. Lightning
   activity with this cluster of storms has been more frequent. With
   eastward extent, these storms will encounter a capped airmass across
   western South Dakota, with MLCAPE 500-1000 J/kg. Enhanced mid-level
   flow across this region is supporting 40-45 kts of deep layer shear,
   which may aid in maintaining organized storms in the near term. The
   00z RAOB from Rapid City shows MLCIN to be generally weak amid steep
   low to mid-level lapse rates. Potential for strong to severe winds
   and large hail will continue across Wyoming into western South
   Dakota in the near term.
