Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Aug 21, 2:10 PM MDT, 5 hours 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 210 PM MDT SAT AUG 21 2004 .DISCUSSION...FORECAST CONCERNS ARE TEMPERATURES AS ABOVE NORMAL READINGS RETURN TO THE AREA AFTER A RATHER COOL AUGUST. OTHER CONCERN IS PINNING DOWN CONVECTION TONIGHT AND OVERNIGHT CONVECTION MONDAY NIGHT. AT 20Z SURFACE TROUGH WAS EVIDENT OVER THE NORTHWEST CORNER OF THE FORECAST AREA PER WINDSHIFT/SATELLITE OBSERVATIONS BETWEEN AKRON AND YUMA. WITHIN THE DEEPER MOISTURE/DEWPOINTS ALONG THE CO/KS BORDER WERE SOME WEAK CUMULUS CLOUDS. TONIGHT/SUNDAY...SURFACE TROUGH GETS HUNG UP OVER THE NORTHWEST HALF OF THE AREA THROUGH MIDNIGHT WHERE COMBINATION OF THETA-E CONVERGENCE AND WINDSHIFT LINE SHOULD PROVIDE ENOUGH FOCUS FOR EARLY EVENING CONVECTION...DECREASING AFTER MIDNIGHT. DESPITE STEEP LAPSE RATES AND WEAK INSTABILITY I CANT SEE ANYTHING IN THE CONVERGENCE/OMEGA FIELDS PROMPTING ME TO INSERT SOME LATE AFTERNOON STORMS. SUNDAY NIGHT/MONDAY...SOUTH TO SOUTHWEST WINDS CONTINUE AT THE SURFACE WHILE THE UPPER LOW CENTER ROTATES NORTHEAST INTO CANADA. WITH THE TROUGH ACROSS THE NORTHWEST AND BROAD RIDGE OVER THE SOUTHEAST WE BECOME CAUGHT IN A SOUTHWEST FLOW ALOFT. THIS WILL PROMOTE A WARMING TREND SUGGESTED BY THE ETA/UKMET THAN THE NGM/GFS. LATE MONDAY LOOKS TO HAVE THE BEST CHANCE OF LIGHT PRECIP... ESPECIALLY OVER THE EAST WHERE COMBINATION OF SURFACE WIND CONVERGENCE COINCIDES WITH 850/700 THETA-E AXIS AND 850 RH GRADIENT. MID LEVEL LAPSE RATES ALSO RATHER STEEP. MONDAY NIGHT/TUESDAY...CURRENT AND PREVIOUS GFS IN GREAT AGREEMENT PLACING A SURFACE LOW NEAR NORTHEAST NEBRASKA. SURFACE WINDS TURN MORE WESTERLY OVER THE WESTERN HALF OF THE AREA BEFORE PRESSURE FALLS OVER FAR EASTERN COLORADO BRING THEM BACK TO A SOUTHWESTERLY DIRECTION. TEMPERATURES COOL ONLY A FEW DEGREES BUT APPEAR TO REMAIN ABOVE NORMAL. IN THE EXTENDED PERIODS (WEDNESDAY-SATURDAY)...FOR WEDNESDAY AND THURSDAY CURRENT AND PREVIOUS 2 RUNS OF THE GFS ALONG WITH DGEX ADVERTISE WARM SOUTHWEST WINDS AHEAD OF THE NORTHWEST UPPER TROUGH. WITH POSSIBLE DRYSLOTTING OVER THE AREA PLENTY OF SUNSHINE SHOULD REALIZE 850 TEMPERATURES OF MID 80S TO LOWER 90S WEDNESDAY...90S ON THURSDAY. COOLER AIR TRIES TO COME THURSDAY NIGHT PER ECMWF/DGEX/GFS WITH TEMPERATURES COOLING BACK INTO THE LOW TO 80S FOR FRIDAY. ON SATURDAY...LATEST GFS DOESNT VEER WINDS AROUND TO THE SOUTHEAST AS THE PREVOIUS RUN DID. INSTEAD...IT KEEPS THE AREA UNDER NORTHEAST TO EAST WINDS. THIS IMPACTS THE TEMPERATURES AT 850 BY 5F OR SO BUT GIVEN SURROUNDING OFFICES GRIDS AND SOME DISPERITY WILL GO LOW/MID 80S. WILL TREND TOWARD THE LATEST GFS AND NOT BRINGS WINDS AROUND TO THE SOUTH AS FAST AS PREVIOUS GFS ADVERTISED. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. NE...NONE. CO...NONE. && DDT

AS TEMPERATURES RISE INTO THE MID TO UPPER 80S THIS AFTERNOON...THE ATMOSPHERE WILL BECOME SUFFICIENTLY UNSTABLE FOR THUNDERSTORMS TO DEVELOP IN FAR EAST COLORADO. WIDELY SCATTERED THUNDERSTORMS ARE EXPECTED TO BEGIN TO DEVELOP AROUND 3 PM MDT. ANY STORMS THAT DO DEVELOP SHOULD DRIFT EAST TO SOUTHEAST INTO WESTERN KANSAS AND EXTREME SOUTHWEST NEBRASKA DURING THE EVENING BEFORE DISSIPATING. THE BEST CHANCE FOR STRONG STORMS...ALBEIT SLIGHT...IS SOUTH AND WEST OF A LINE FROM NEAR YUMA TO BONNY RESERVOIR IN COLORADO THEN CONTINUING SOUTHEAST TO SHARON SPRINGS TO LEOTI IN KANSAS. THE GREATEST THREAT FROM THESE STORMS WILL BE DEADLY CLOUD TO GROUND LIGHTNING AND SMALL HAIL. ALTHOUGH NONE OF THESE STORMS IS EXPECTED TO BECOME SEVERE...DUE TO THE WEAK WIND SHEAR STRUCTURE OF THE ATMOSPHERE...AN ISOLATED STORM WITH LARGE HAIL AND DAMAGING WIND CANNOT BE RULED OUT. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY THERE IS A SLIGHT CHANCE OF THUNDERSTORMS SUNDAY AFTERNOON EAST OF A LINE FROM GOVE KANSAS TO MCCOOK NEBRASKA.
