   Concerning...Severe Thunderstorm Watch 564...

   Valid 300423Z - 300630Z

   The severe weather threat for Severe Thunderstorm Watch 564
   continues.

   SUMMARY...An organized cluster of thunderstorms with strong to
   occasionally severe wind gusts likely will be maintained at least
   into the 1-2 AM CDT time frame, before beginning to weaken.

   DISCUSSION...The ongoing cluster of storms is maintaining
   organization, with a modest surface cold pool including 2 hourly
   pressure rises around 2 mb and a still relatively well-defined MCV
   progressing eastward to the southeast of Jamestown.  Eastward
   propagation of the cold pool has been around 35-40 kt, resulting in
   strong easterly inflow of moist boundary-layer air characterized by
   CAPE on the order of 2000+ J/kg.  As the gust front passes east of
   the Minnesota state border between Ortonville MN and Fargo ND by
   around 0530Z, inflow may begin to become less moist and unstable,
   and more substantive weakening trends may ensue.  Until then,
   though, strong to occasionally severe gusts probably will be
   maintained.
