FOR PORTIONS OF NORTHERN ALABAMA INTO MIDDLE AND EASTERN TENNESSEE AND SOUTHEAST KENTUCKY Mesoscale Discussion 2313 NWS Storm Prediction Center Norman OK 0639 PM CST Sat Dec 09 2023 Areas affected...portions of northern Alabama into middle and eastern Tennessee and southeast Kentucky Concerning...Tornado Watch 715... Valid 100039Z - 100215Z The severe weather threat for Tornado Watch 715 continues. SUMMARY...The severe threat continues across Tornado Watch 715. Damaging gusts appear to be the main threat, though a couple of tornadoes remain possible, especially with storms closer to the TN/AL border. The severe threat may persist eastward into northeast AL and southeastern TN, where a WW issuance may ultimately be warranted. DISCUSSION...Thunderstorms have recently been merging into a loosely organized squall line across middle TN into eastern MS and far northwest AL, with MRMS mosaic radar data showing these storms percolating in intensity. Low-level shear should remain strong across the region as a 35+ kt low-level jet overspreads the TN Valley (per 00Z mesoanalysis). Given linear storm modes, damaging gusts should become the primary threat into the evening hours. However, a few discrete cells remain near the AL/TN border, and these storms have the best chance at producing a couple of tornadoes into early tonight. Despite waning buoyancy, the strong deep-layer and low-level shear should compensate amid 500 J/kg MLCAPE to support some continuance of severe potential into northeast AL and southeastern TN. Though damaging gusts may be the main threat, given linear structures, the elongated and curved hodographs suggest that some tornado potential will also exist. A downstream Tornado Watch issuance may ultimately be needed. ..Squitieri/Goss.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MRX...JKL...FFC...LMK...OHX...HUN...
