Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

What forecasters said that day
The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this tornado warning went out at Jun 15, 3:09 PM MDT, 35 minutes earlier.
Area forecast discussion, Jun 15, 3:09 PM MDT, 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 309 PM MDT MON JUN 15 2009 .SHORT TERM...CONVECTION COMMENCED IN EARNEST BY 1 PM MDT...MAIN FOCUS IS/WAS OVER THE SOUTHWESTERN PART OF THE CONVERGENCE BOUNDARY STRETCHING FROM CENTRAL DOUGLAS THROUGH NORTHERN WASHINGTON COUNTIES. OTHER STRONG ACTIVITY GOING IN EAST CENTRAL LARIMER/WESTERN WELD COUNTIES RIGHT NOW. MODELS HAVE FAIRLY STRONG WEST-SOUTHWESTERLY FLOW ALOFT FOR THE FORECAST AREA TONIGHT AND TUESDAY. THE QG VERTICAL VELOCITY FIELDS HAVE WEAK DOWNWARD MOTION PROGGED TONIGHT INTO MID DAY TUESDAY...THEN WEAK UPWARD MOTION MOVES IN FROM THE WEST. THE LOW LEVEL WINDS AND PRESSURE FIELDS POINT TO MORE NORMAL DIURNAL DRAINAGE WINDS OVERNIGHT...MAY OPT OUT OF MENTION OF FOG BECAUSE OF IT. FOR MOISTURE...THIS AFTERNOON/ EVENINGS'S CONVECTIVE CLOUDINESS WILL LIKELY GO AWAY FOR THE MOST PART. ON TUESDAY...IT LOOKS LIKE THERE WILL BE PLENTY OF UPPER LEVEL MOISTURE FOR ALL THE FORECAST AREA BY AFTERNOON. BOUNDARY LAYER DEW POINT TEMPERATURES ARE IN THE MID 40S TO UPPER 50S FOR MUCH OF THE PLAINS AND FOOTHILLS TUESDAY AFTERNOON. PRECIPITABLE WATER VALUES ARE IN THE 0.55 TO 0.85 INCH RANGE TUESDAY AFTERNOON FOR THE PLAINS AND LOWER FOOTHILLS. THE THETA-E AXIS IS MAINLY OVER THE SOUTH CENTRAL AND EAST CENTRAL PORTIONS OF THE FORECAST AREA FOR TUESDAY AFTERNOON. THE LAPSE RATES ON THE CROSS SECTIONS SHOW SOME MID LEVEL CAPPING TUESDAY AFTERNOON WITH SOME WARMING AROUND 500 MB. THERE IS SOME CAPE TUESDAY AFTERNOON OVER THE PLAINS AND LOWER FOOTHILLS...BUT IT LOOKS WAY LESS THEN THE CURRENT VALUES THIS AFTERNOON. QPF FIELDS HAVE SOME MEASURABLE RAINFALL TUESDAY AFTERNOON...BUT IT'S PRETTY MEAGER AND DOES NOT COVER ALL THE FORECAST AREA. WILL USE CURRENT SITUATION FOR THIS EVENING'S POPS...THE HIGHEST NUMBER OVER THE EASTERN AREAS OF THE PLAINS WITH THE MOISTURE AND BOUNDARY IN MIND. FOR TUESDAY AFTERNOON...WILL MAKE A FEW MINOR ADJUSTMENTS...BUT WILL STICK WITH 10-30%S...BEST IN THE MOUNTAINS. FOR TEMPERATURES...TUESDAY'S HIGHS ARE PERHAPS 1-3 C WARMER THAN CURRENT HIGHS. WE MAY HIT 80 DEGREES F OR A TAD HIGHER TUESDAY AFTERNOON FOR THE FIRST TIME THIS WHOLE MONTH. THROUGH THE FIRST 15 DAYS OF JUNE...THE HIGH TEMPERATURES IN DENVER HAS YET TO REACH 80 DEGREES. IT'S ACTUALLY GREEN HERE. .LONG TERM...UPPER LEVEL RIDGE WILL BUILD OVER THE CENTRAL PLAINS AND CENTRAL ROCKIES TUESDAY NIGHT AND WEDNESDAY AS AN UPPER LEVEL TROUGH DIGS SOUTH ALONG THE CALIFORNIA COAST. THIS WILL BRING WARMER AND SLIGHTLY DRIER AIR TO THE REGION. MODELS CUT BACK ON THE AMOUNT OF CONVECTION TUESDAY EVENING AND WEDNESDAY. HOWEVER...THE NAM12 SHOWS CAPES OF 1000-3000 J/KG OVER THE PLAINS WEDNESDAY AFTERNOON. DEFINITELY CAN'T RULE OUT THUNDERSTORMS WITH THIS INSTABILITY. DRY AIR WILL MIX DOWN AND HELP TO DROP THE CAPE LATE IN THE AFTERNOON. THERE IS ALSO A CAP AROUND 700 MB. BECAUSE OF THIS...WILL KEEP ISOLATED THUNDERSTORMS IN THE FORECAST FOR THE PLAINS AND SCATTERED POPS FOR THE MOUNTAINS. WILL SEE MORE SHOWERS AND THUNDERSTORMS AS AN UPPER LEVEL TROUGH MOVES ACROSS THE NORTHERN ROCKIES THURSDAY CAUSING THE FLOW ALOFT TO SHIFT WESTERLY. THIS FRONT WILL INCREASE THE LOW LEVEL MOISTURE AND BRING SLIGHTLY COOLER TEMPERATURES. HIGHS WILL COOL OFF ABOUT 5-10 DEGREES BEHIND THE FRONT. MODELS HAVE BEEN VERY CONSISTENT WITH THIS FEATURE OVER THE PAST FEW DAYS. THE RIDGE WILL REBOUND BY FRIDAY AFTERNOON. MODELS NOW SHOWING THE RIDGE WILL SHIFT EAST OVER THE PLAINS OVER THE WEEKEND. THIS WILL RESULT IN A SOUTHWEST FLOW ALOFT OVER COLORADO. THIS PATTERN WILL AGAIN BRING MOISTURE AND INSTABILITY BACK INTO THE AREA. WILL INCREASE POPS INTO THE 20-30 PERCENT RANGE FOR THE WEEKEND AND EARLY NEXT WEEK. IF MODELS CONTINUE TO SHOW THIS PATTERN...POPS WILL NEED TO BE INCREASED MORE AS THE WEEKEND NEARS. THE SLIGHTLY STRONGER RIDGE OVER THE PLAINS WILL ALLOW TEMPERATURES TO BE NEAR NORMAL VERSUS THE PAST WEEK. && .AVIATION...WINDS WILL LIKELY GO THE NORMAL DIURNAL DRAINAGE BY MID TO LATE EVENING AND CONTINUE INTO TUESDAY MORNING. IT SHOULD KEEP THE STRATUS AND FOG AT BAY FOR THE AIRPORTS. THE THUNDERSTORM THREAT SHOULD BE PRETTY LOW AFTER THIS CURRENT BATCH OF CONVECTION EXISTS THE BIG AIRPORT. THE THREAT OF STORMS WILL BE PRETTY LOW TUESDAY AFTERNOON AS WELL. && .BOU WATCHES/WARNINGS/ADVISORIES...NONE. RJK/MEIER

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL COLORADO. .DAY ONE...TODAY AND TONIGHT SHOWERS AND THUNDERSTORMS ARE BEGINNING TO DEVELOP OVER THE MOUNTAINS AND FOOTHILLS LATE THIS MORNING. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP IN THESE AREAS AND SPREAD OUT ONTO THE PLAINS EARLY THIS AFTERNOON. ANOTHER UPPER LEVEL WEATHER DISTURBANCE IS EXPECTED TO ENHANCE THUNDERSTORM DEVELOPMENT THIS AFTERNOON. THERE IS ALSO A CONVERGENCE BOUNDARY STRETCHING FROM CENTRAL DOUGLAS ACROSS NORTHWESTERN ELBERT... THROUGH EASTERN ARAPAHOE AND EASTERN ADAMS ON INTO NORTHERN WASHINGTON COUNTIES. THIS COULD ALSO PROVIDE THE IMPETUS FOR THUNDERSTORM DEVELOPMENT. ALL OF THE NORTHEAST PLAINS HAVE A CHANCE OF SEVERE THUNDERSTORMS THIS AFTERNOON...BUT THE HIGHEST CHANCES FOR SEVERE THUNDERSTORMS WILL BE ALONG AND EAST OF THE ABOVE MENTIONED CONVERGENCE LINE. THE STRONGEST STORMS MAY PRODUCE HAIL UP TO TWO INCHES IN DIAMETER ALONG WITH DAMAGING WINDS. LIKE YESTERDAY...THE OVERALL TORNADO THREAT IS LOW...BUT AN ISOLATED WEAK TORNADO IS STILL POSSIBLE... ESPECIALLY IN THE VICINITY OF THE CONVERGENCE LINE. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY CHANCES FOR THUNDERSTORMS WILL DECREASE TUESDAY AND WEDNESDAY AS WARMER AND DRIER CONDITIONS ASSOCIATED WITH A HIGH PRESSURE RIDGE MOVE OVER THE STATE. BY THURSDAY...THUNDERSTORM CHANCES INCREASE AGAIN AS A LOW PRESSURE SYSTEM MOVES OUT OF THE PACIFIC NORTHWEST AND ACROSS COLORADO BRINGING WITH IT SLIGHTLY COOLER TEMPERATURES. WARMER AND DRIER CONDITIONS WILL RETURN FRIDAY AND FOR THE WEEKEND. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED AFTER 1 PM ACROSS THE NORTHEAST PLAINS. RJK
