   Areas affected...much of southern Missouri into eastern Oklahoma and
   western Arkansas

   Concerning...Tornado Watch 205...208...

   Valid 082050Z - 082245Z

   The severe weather threat for Tornado Watch 205, 208 continues.

   SUMMARY...The threat of supercells producing very large hail,
   tornadoes and damaging gusts persists from southern Missouri into
   northeast Oklahoma, with additional storms anticipated farther

   DISCUSSION...Several supercells exist along a front from northeast
   OK into southwest MO, with addition activity just on the cool/north
   side of an east-west oriented outflow boundary from the earlier MCS.
   This boundary appears to be mixing out, as temperatures are
   recovering over south-central MO near the front.  Given time of day,
   additional pockets of air mass recovery are possible with tornado
   potential remaining.

   Farther south, extreme instability persists over eastern OK into
   western AR, and convergence near the cold front in OK is expected to
   yield at least isolated supercells. These will have very large hail
   potential, along with periodic tornado threat as 0-1 SRH remains
   above 100 m2/s2.
