Mesoscale Discussion 0707 NWS Storm Prediction Center Norman OK 0341 PM CDT Wed May 08 2024 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. ..Grams.. 05/08/2024 ...Please see www.spc.noaa.gov for graphic product...
