   Areas affected...southern Missouri

   Concerning...Severe Thunderstorm Watch 622...

   Valid 261951Z - 262115Z

   The severe weather threat for Severe Thunderstorm Watch 622
   continues.

   SUMMARY...Broken line of storms will continue to pose a risk for
   isolated damaging wind and large hail as it continues through
   southern MO this afternoon.

   DISCUSSION...Broken line of storms from Rolla to near Springfield
   continues southeast at 35-40 kt. Storms are moving into an
   environment characterized by warmer air near 700 mb, and recent
   trend has been for storms to become more discrete including what
   appears to be a supercell approaching Springfield. Storms are moving
   along instability gradient with downstream temperatures in the upper
   80s along with low to mid 70s F dewpoints supporting 2500-3000 J/kg
   MLCAPE. VWP data from Springfield also show veering low-level wind
   profiles with 50+ kt 0-6 km shear favorable for embedded organized
   structures.
