825 ACUS11 KWNS 160048 SWOMCD SPC MCD 160047 IAZ000-NEZ000-SDZ000-160215- Mesoscale Discussion 1279 NWS Storm Prediction Center Norman OK 0747 PM CDT Sat Jun 15 2024 Areas affected...Northeast NE into northwest IA and extreme southeast SD Concerning...Tornado Watch 418... Valid 160047Z - 160215Z The severe weather threat for Tornado Watch 418 continues. SUMMARY...The tornado threat will continue through dusk, along with some potential for locally damaging wind and hail. DISCUSSION...A supercell cluster has evolved across northeast NE this evening, with multiple reports of confirmed tornadoes over the last 1-2 hours. The immediate downstream environment remains favorable for tornadic supercells, with MLCAPE in excess of 2000 J/kg, backed surface winds, and rather strong low-level shear/SRH still noted in VWPs from KFSD and KOAX. Any persistent supercells will continue to pose a tornado threat through dusk within this environment, along with some isolated hail potential. With time, there is some potential for a small bowing segment to evolve out of the ongoing cluster, which could result in a somewhat greater threat for damaging wind as convection spreads into northwest IA, in addition to some continued tornado potential. ..Dean.. 06/16/2024 ...Please see www.spc.noaa.gov for graphic product...
