Mesoscale Discussion 0972 NWS Storm Prediction Center Norman OK 1017 AM CDT Sun May 26 2024 Areas affected...portions of central Kentucky into northern Tennessee Concerning...Tornado Watch 315... Valid 261517Z - 261645Z The severe weather threat for Tornado Watch 315 continues. SUMMARY...The severe threat continues across Tornado Watch 315. A bow echo will continue to progress eastward with a damaging wind threat, and a few more QLCS tornadoes remain possible. DISCUSSION...A well organized bow echo MCS, with a history of severe wind gusts, wind damage, and occasional QLCS tornadoes, continues to rapidly track eastward across portions of the TN Valley. At the moment, the bow appears slightly less robust compared to earlier stages, perhaps due to gradually waning instability with eastward extent. Nonetheless, the Kentucky mesonet continues to show widespread 45-55 mph wind gusts occurring with the bow, with regional radars also depicting occasional, brief QLCS circulations developing. With adequate vertical wind shear, over 2000 J/kg MLCAPE and weakening MLCINH (given diurnal heating) preceding the bow, damaging gusts (perhaps exceeding severe limits at times) should continue across much of the rest of KY and northern TN. A couple of additional QLCS tornado also cannot be ruled out. ..Squitieri.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MRX...JKL...LMK...OHX...
