SURVEY SUMMARY
AROUND MIDNIGHT ON 6 AUGUST 2026, A CLUSTER OF SEVERE
THUNDERSTORMS ADVANCING INTO CASS COUNTY DEVELOPED SEVERE OUTFLOW

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

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.
