Mesoscale Discussion 1992 NWS Storm Prediction Center Norman OK 1050 PM CDT Sun Aug 25 2024 Areas affected...Northeast SD Concerning...Severe Thunderstorm Watch 647... Valid 260350Z - 260515Z The severe weather threat for Severe Thunderstorm Watch 647 continues. SUMMARY...A localized damaging-wind threat may spread into northeast South Dakota. DISCUSSION...Persistent convection has evolved into a small outflow-driven cluster moving across east-central SD, with some increase in storm intensity and inbound radar velocities from KABR recently noted. This cluster may continue to spread north-northeastward, within a corridor of deeper low-level moisture, stronger MLCAPE, and somewhat weaker MLCINH (as noted per recent RAP analyses). Localized severe gusts may accompany this cluster through late evening as it moves into northeast SD. Observational trends will be monitored regarding the need for local watch expansion, if this cluster remains organized to the edge of WW 647. ..Dean.. 08/26/2024 ...Please see www.spc.noaa.gov for graphic product...
