ACUS11 KWNS 070056 SWOMCD SPC MCD 070056 MOZ000-KSZ000-IAZ000-NEZ000-070200- Mesoscale Discussion 1548 NWS Storm Prediction Center Norman OK 0756 PM CDT Sat Jul 06 2024 Areas affected...Lower Missouri Valley region Concerning...Severe Thunderstorm Watch 509... Valid 070056Z - 070200Z The severe weather threat for Severe Thunderstorm Watch 509 continues. SUMMARY...Damaging wind threat continues this evening. DISCUSSION...MCS that developed over south-central NE has matured as it propagates east along the NE/KS border toward southwest IA/northwest MO. Latest diagnostic data depicts a broad reservoir of buoyancy (1000-1500 MLCAPE) that has yet to be overturned immediately ahead of this complex. With the LLJ beginning to strengthen over northeast KS there is reasonable confidence this MCS should advance beyond the MO River before any appreciable weakening occurs. Damaging winds are the primary risk with this convection. ..Darrow.. 07/07/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...EAX...OAX...TOP...GID...
