   Areas affected...Mid-MS/Lower OH and TN Valleys

   Concerning...Tornado Watch 204...206...209...

   Valid 082041Z - 082215Z

   The severe weather threat for Tornado Watch 204, 206, 209 continues.

   SUMMARY...Numerous supercells are ongoing and will continue to pose
   threats for significant severe weather during the next several
   hours. Additional/expansion of tornado watches with south-southeast
   extent and replacement/extension of parts of WW 206 (which is
   scheduled to expire at 22Z) should be expected through early
   evening.

   DISCUSSION...An outbreak of supercells is underway from the Ozark
   Plateau across the Mid-MS and Lower OH into the TN Valleys. These
   storms will remain capable of producing tornadoes, large to very
   large hail, and damaging winds for the next several hours. Greatest
   tornado threat in the next few hours should be focused within three
   regimes. One along, the residual outflow that extends in a
   west/east-orientation across southern MO. The second with the
   long-lived supercell cluster along the tight buoyancy gradient over
   far southern IL into western KY. And the third area across middle TN
   into south-central KY, where the strongest low-level shear exists
   near/north of the modified convective outflow from earlier today.
   The southern/eastern extent of the supercell development in the TN
   Valley will likely necessitate additional tornado watches this
   evening.
