Valid 242252Z - 250045Z The severe weather threat for Severe Thunderstorm Watch 681 continues. SUMMARY...Some hail/wind threat continues with scattered storms this evening. DISCUSSION...Short-wave trough is ejecting across the OH Valley early this evening and scattered strong/severe convection continues within the warm-advection zone, well ahead of the front. Over the last few hours, greatest concentration of robust, long-lived updrafts/supercells is beneath the strongest mid-level flow across eastern KY/northeast TN. Radar data suggests at least 4-6 supercells, extending 50mi either side of the TN/KY border, moving east-northeast toward western VA/southwest WV. However, air mass is notably less buoyant downstream and these updrafts will encounter increasingly hostile environment across the higher terrain and points east. Until then, hail/wind threat will continue with these storms. ..Darrow.. 09/24/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RNK...RLX...MRX...JKL...LMK...OHX...
