   The severe weather threat for Severe Thunderstorm Watch 281
   continues.

   SUMMARY...Large hail and damaging winds will remain threats with
   storms in WW 281. The greatest hail and tornado threat appears to be
   with a supercell in Adams/Hettinger Counties. Continued convective
   development noted on radar indicates that upscale growth is likely
   to occur over the next several hours. Damaging wind gusts will
   become the greatest threat as that process unfolds.

   DISCUSSION...Storm coverage within WW has remained rather isolated.
   However, visible satellite and radar trends indicate further
   convective development is occurring, particularly along the MT/ND
   border. A potent supercell moving northeast into Adams/Hettinger
   Counties has produced near 2 inch hail and a recent 66 mph wind
   gust. With greater convective coverage probable as the
   afternoon/evening progresses, the threat for very large hail will
   diminish with damaging winds becoming an increasing concern. The
   southernmost storm may be able to continue northeastward with
   uncontaminated inflow as storm development to the southeast of it
   does not look likely based on observational trends. As such, the
   largest hail is likely to be produced by this storm. Furthermore,
   with better moisture and stronger southeasterly winds downstream,
   the potential for a tornado may be maximized in the next 1-2 hours.
