Mesoscale Discussion 0703 NWS Storm Prediction Center Norman OK 0150 PM CDT Wed May 08 2024 Areas affected...parts of the Mid-MS...Lower OH...and TN Valleys Concerning...Tornado Watch 204...206... Valid 081850Z - 081945Z The severe weather threat for Tornado Watch 204, 206 continues. SUMMARY...Very large hail, isolated severe wind gusts, and tornadoes will remain probable with mature supercells across parts of the Mid-Mississippi to Lower Ohio and Tennessee Valleys through the rest of the afternoon. DISCUSSION...Several supercells are ongoing with two distinct regimes. An intense, long-track supercell in cluster regime persists across a part of the Mid-MS Valley, between STL and CGI. Numerous large hail up to baseball size have been reported during the past hour. This supercell cluster should continue to evolve east along the tight instability gradient across southern IL, with potential for further upscale growth along its southwest flank. Damaging winds of 70-80 mph, along with attempts at occasional tornadogenesis will remain possible. Farther southeast, more discrete supercells continue to increase/mature. Low-level SRH is relatively greater across south-central KY into northern Middle TN near/northeast of the residual outflow from the morning MCS. Low-level flow has become veered to the southwest per time-series of PAH VWP data, tempering warm-sector hodograph enlargement. Overall, a mix of all severe hazards, some of which may be significant, is anticipated in/near both tornado watches through 22Z. ..Grams.. 05/08/2024 ...Please see www.spc.noaa.gov for graphic product...
