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.
