Mesoscale Discussion 0100 NWS Storm Prediction Center Norman OK 0609 PM CST Sat Feb 15 2025 Areas affected...western Tennessee and southwestern Kentucky Concerning...Tornado Watch 8... Valid 160009Z - 160145Z The severe weather threat for Tornado Watch 8 continues. SUMMARY...Tornado threat continues within WW008. Threat will continue downstream into portions of Middle Tennessee and Western Kentucky. DISCUSSION...A broken line of thunderstorms has shown an uptick in intensity over the last hour across the Arkansas/Tennessee border. Line embedded supercells are observed, with activity ahead of the main line also exhibiting rotation. The low level jet, with axis currently from central LA to middle TN/southern KY, is progged to continue strengthening through the evening, with low level shear becoming more favorable. This strong southerly flow has also ushered in deeper moisture and a more favorable air mass across western Tennessee, steadily approaching southern Kentucky. Given the progress of the main line, maintenance of individual cells ahead of the line will be difficult. However, deep layer shear of 50-55 kts will continue to support line embedded mesocyclones and potential for damaging wind and tornadoes. This threat is spreading eastward and will likely necessitate a downstream watch into southern Kentucky soon. ..Thornton/Hart.. 02/16/2025 ...Please see www.spc.noaa.gov for graphic product...
