   The severe weather threat for Severe Thunderstorm Watch 321
   continues.

   SUMMARY...An isolated threat for mainly damaging winds continues
   in/near Severe Thunderstorm Watch 321.

   DISCUSSION...Recent radar imagery shows a well developed MCS arcing
   along/near the MO River. The strongest portion of this line is along
   the southern flank, where modest (30-35 kt) moisture influx is
   occurring in tandem with a low-level jet. A reservoir of very strong
   to extreme MUCAPE (4000-5000+ J/kg) is present to the
   south-southeast of the southern flank. Current expectations are for
   the MCS to move southeastward along an instability gradient into
   northeastern KS and northwestern MO over the next couple of hours.
   Given the linear mode, isolated damaging wind gusts from
   thunderstorm outflow will likely remain the primary threat. The
   greatest wind threat may focus where updrafts and corresponding
   reflectivity can remain in close proximity to the outflow, which has
   surged ahead of the line in most areas.
