   Areas affected...Portions of northwestern Nebraska...portions of
   southern South Dakota

   Concerning...Severe Thunderstorm Watch 175...

   Valid 180053Z - 180300Z

   The severe weather threat for Severe Thunderstorm Watch 175
   continues.

   SUMMARY...A few more intense storms will continue to trek
   north/northeast into the watch over the next couple of hours. Severe
   hail will still be possible, particularly in southern areas of the
   watch.

   DISCUSSION...A couple of intense storms in north-central Nebraska
   will continue moving north/northeast. Theses supercells will be
   capable of producing severe hail. However, as storms continue moving
   north, the decrease in instability will limit overall storm
   severity. Only marginally severe hail is likely with any storms that
   move farther north.
