Mesoscale Discussion 2056 NWS Storm Prediction Center Norman OK 0726 PM CDT Tue Sep 09 2025 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 609... Valid 100026Z - 100230Z The severe weather threat for Severe Thunderstorm Watch 609 continues. SUMMARY...Hail threat is expected to persist with storms this evening, along with some wind risk. DISCUSSION...Isolated strong-severe thunderstorms are shifting slowly southeast across the central High Plains this evening. Strong boundary-layer heating has proven instrumental in this activity attaining severe levels as lapse rates are seasonally steep across this region. However, over the next few hours, nocturnal cooling will lead to increasing CINH and surface-based updrafts should being to struggle as they decouple from the boundary layer. 00z sounding from DDC exhibits this trend with weak inhibition noted around 1km. Even so, LLJ is forecast to increase after sunset and this should aid one or more elevated thunderstorm clusters that should propagate across western KS. Hail is the primary concern with this activity. ..Darrow.. 09/10/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DDC...GLD...PUB...BOU...
