Peak Wind /E/: 70 to 100 mph Path Length /statute/: Approx. 9.00 miles Path Width /maximum/: Approx. 2 miles Fatalities: 0 Injuries: 0 Start Date: Aug 05 2026 Start Time: 1157 PM CDT Start Location: Belton, MO Start Lat/Lon: 38.81 / -94.53 End Date: Aug 06 2026 End Time: 1212 AM CDT End Location: S. Lee's Summit, MO End Lat/Lon: 38.84 / -94.37 .Survey Summary... Around midnight on 6 August 2026, a cluster of severe thunderstorms advancing into Cass County developed severe outflow winds in excess of 70 to 80 mph, with pockets of significantly severe, 90 to 100 mph, wind gusts across northwestern Cass County Missouri, from Belton to Raymore, and into southern Jackson County, impacting neighborhoods in far south Lee's Summit. As two separate thunderstorms merged moving into Cass County, with significant influence from the low level jet stream, a swath of severe outflow winds developed near I-49/US 71 in northern Belton, increasing in intensity as the storm surged across northern Raymore over the Creekmore Neighborhood. Radar analysis found divergent downburst signatures indicative of widespread 80+ mph wind gusts with pockets of radial downburst signatures suggesting wind speeds approaching 90 to 100 mph along the Cass/Jackson border from Creekmore, in Raymore, to Stony Creek in Lee's Summit. NWS Damage survey confirmed widespread 70 to 80 mph wind damage, primarily to trees and unsecured items, with a wide swatch along the damage path, with pockets of 80 to 90 mph damage to trees and structures. Early in the event, significant damage was noted est of I-49/US 71 to a distribution warehouse where a prefabricated concrete wall failed. The most significant damage was found just east-northeast of Creekmore, where large trees were toppled and significant damage occurred to a steel frame constructed equestrian show barn. Wind speeds were estimated to be between 95 and 100 mph based on the damage to trees and the equestrian barn. The survey found additional damage to trees and minor structure damage into the Stony Creek and Rain TRee Lake neighborhoods of south Lee's Summit. && NOTE: The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data. $$
