PUBLIC INFORMATION STATEMENT

...NWS DAMAGE SURVEY FOR 08/19/2026 THUNDERSTORM WIND EVENT - INITIAL REPORT...
EARLY IN THE MORNING OF WEDNESDAY AUGUST 19TH 2026, MULTIPLE
ROUNDS OF THUNDERSTORMS MOVED THROUGH THE KANSAS CITY METRO,
BRINGING WIND, HAIL, AND HEAVY RAINFALL THAT CONTINUED THROUGH THE
OVERNIGHT HOURS. BETWEEN 1 AM CDT AND 2 AM CDT, AN ELEVATED
SUPERCELL THUNDERSTORM MOVED ACROSS WYANDOTTE COUNTY KANSAS, AND
INTO NORTH KANSAS CITY, MO AND DOWNTOWN KANSAS CITY, MO,
CONTINUING THROUGH INDEPENDENCE, MO AND EASTERN COMMUNITIES. HAIL
UP TO GOLF BALL SIZE OCCURRED IN PORTIONS OF WYANDOTTE COUNTY.
THIS STORM ALSO PRODUCED COPIOUS AMOUNTS OF SUB-SEVERE HAIL
STONES, THAT ACCUMULATED TO DEPTH OF A FEW INCHES ON SOME
SURFACES. EXTENSIVE WIND DAMAGE OCCURRED IN KANSAS CITY, KS
NEIGHBORHOODS EAST OF INTERSTATE 635 AND NORTH OF INTERSTATE 70.
THE QUINDARO AREA OF KANSAS CITY, KS EXPERIENCED THE MOST
EXTENSIVE DAMAGE. THE DAMAGE TO TREES AND BUILDINGS IN THIS
NEIGHBORHOOD IS CONSISTENT WITH THAT OF STRAIGHT-LINE THUNDERSTORM
WIND DAMAGE, BETWEEN 70 AND 80 MPH.
THE MOST EXTENSIVE DAMAGE TO BUILDINGS OCCURRED WITH THE WEST
FACING WALLS, OR THE WEST END OF ROOF STRUCTURES, WITH DAMAGE
THAT TRAVELED FROM WEST TO EAST. REVIEWING RADAR SIGNATURES FROM
THE NWS DOPPLER RADAR IN PLEASANT HILL (KEAX), VERTICAL CROSS
SECTIONS REVEALED A RAPIDLY DESCENDING CORE ON THE SUPERCELL
THUNDERSTORM THAT STARTED JUST AFTER CROSSING INTERSTATE 635, TO
JUST EAST OF THE DOWNTOWN WHEELER AIRPORT (MKC). WE ALSO REVIEWED
RADAR DATA FROM THE MCI TDWR. AS THESE STORMS MOVED OUT OF
LEAVENWORTH COUNTY, KS AND CONTINUED EASTWARD ACROSS THE KANSAS
CITY METRO, MULTIPLE DIVERGENCE SIGNATURES WERE NOTED, ESPECIALLY
AS THE STORM WAS INSIDE THE INTERSTATE 435 LOOP. STRONGER
DIVERGENCE SIGNATURES ARE INDICATIVE OF A DOWNBURST. ONE OF THESE
SIGNATURES WAS NOTED AS IT CROSSED EAST OF INTERSTATE 635, AS IT
ENTERED THE QUINDARO NEIGHBORHOOD. WITH THIS DOWNBURST, THE TMCI
RADAR SAMPLED THE NORTH AND SOUTH WINDS AROUND 40 MPH, AND IN THIS
DOWNBURST, THE WINDS SPREAD OUT IN ALL DIRECTIONS. THE SUPERCELL
STORM WAS MOVING BETWEEN 30-35 MPH ACROSS THE METRO IN AN EASTWARD
DIRECTION. ADDING THE EASTWARD STORM MOTION TO THE EAST-WEST
COMPONENT OF THE WIND, WOULD BE CAPABLE OF CREATING A WEST WIND
(WIND THAT MOVES FROM THE WEST TO THE EAST) BETWEEN 70-75 MPH. THE
DAMAGE TO TREES, AND BUILDINGS IN THE NEIGHBORHOOD ARE CONSISTENT
WITH WINDS BETWEEN 70 AND 80 MPH.
