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 Jul 4, 3:00 PM MDT, 4 hours 43 minutes earlier.
Area forecast discussion, Jul 4, 3:00 PM MDT, 4 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 300 PM MDT SUN JUL 4 2010 .SHORT TERM...THE PLAINS ARE BEGINNING TO DESTABILIZE AS MORE AND MORE CELLS FIRING OFF THE FOOTHILLS ARE ABLE TO MOVE FARTHER EAST. HOWEVER...LOOKING AT THE VERTICAL DEVELOPMENT OF THE CU OUTSIDE AND AT ACARS SOUNDINGS...THERE IS QUITE A STRONG CAP THAT REMAINS. AS THE UPPER TROUGH CURRENTLY OVER UTAH MOVES CLOSER AND PROVIDES AN INCREASE IN QG LIFT AND THE OVERCAST SKIES NOW CLEARING PROVIDING HEATING FROM BELOW...SHOULD HELP BREAKDOWN THE CAP MID TO LATE AFTERNOON. CURRENTLY A FEW STORMS OVER THE PALMER DIVIDE HAVE BEEN ABLE TO SUSTAIN FOR A BIT AS THEY ARE OVER HIGHER TERRAIN AND THE CAP IS WEAKENING EASIER THERE. A TORNADO HAS BEEN ISSUED FOR THE NORTHERN COLORADO BORDER AS STORMS IN WYOMING HAVE BEEN PRODUCING SEVERAL TORNADOES. BELIEVE IT WILL STILL BE A FEW MORE HOURS BEFORE WE SEE ANYTHING REALLY GET GOING STRONG IN OUR FORECAST AREA. STORMS OVER THE HIGHER TERRAIN WILL HELP WEAKEN THE CAPPED MOIST ENVIRONMENT ON THE PLAINS IN THE LATE AFTERNOON AND EVENING. WINDS ALOFT WILL HELP THE STORMS MOVE ABOUT 10 TO 15 KNOTS SO MAJOR FLOODING IS NOT EXPECTED. HOWEVER WITH SUCH A MOIST ENVIRONMENT STORMS WILL HAVE THE POTENTIAL THIS EVENING AND TONIGHT TO PRODUCE HEAVY RAIN IN EXCESS OF 2 INCHES AN HOUR OUT OF THE STRONGER STORMS. AS THESE STORMS BECOME MORE NUMEROUS...SMALL STREAMS AND STREETS MAY HAVE SMALL FLOODING ISSUES. MIXED LAYER CAPES OF AROUND 1000 J/KG AND ENOUGH SHEAR WITH COOLING ALOFT FROM THE PASSING UPPER TROUGH LATER TONIGHT WILL ALLOW LARGE HAIL AND A POSSIBLE TORNADO BE THE MAIN THREATS. EXTENDED HIGHER POPS THIS EVENING AND SLOWED THE DECREASE EVEN FURTHER AS THE UPPER LOW WILL NOT PASS OVER NORTHEASTERN COLORADO UNTIL EARLY MONDAY MORNING. COULD SEE SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS PAST MIDNIGHT INTO THE MORNING HOURS OVER THE EASTERN PLAINS. TOMORROW WILL BE A MUCH QUIETER DAY AS SUBSIDENCE ON THE BACKSIDE OF THE TROUGH KEEPS POPS TO A MINIMUM. ONLY THE MOUNTAINS HAVE A SLIGHT CHANCE OF A FEW LIGHT RAIN SHOWERS AS DRIER AIR MOVES IN. TEMPERATURES WILL BE SIMILAR TO TODAY WITH SLIGHT WARMING OVER THE PLAINS BY A FEW DEGREES. WINDS WILL BE LIGHT SO NO FIRE WEATHER CONCERNS. .LONG TERM...THE NEXT IN A SERIES OF ACTIVE SHORTWAVE IMPULSES SWING OUT OF THE PACIFIC NORTHWEST AND ACROSS NORTHERN COLORADO TUESDAY AFTERNOON INTO WEDNESDAY...ONCE AGAIN IMPACTING AREAS MAINLY EAST OF THE FRONT RANGE. A SFC COLD FRONT ORGANIZING OUT AHEAD OF THE MAIN TROUGH IS PROGGED BY THE NAM TO GFS TO SLIDE SOUTHWARD OUT OF SRN WYOMING/WRN NEBRASKA AND ACROSS NERN COLORADO BY LATE TUESDAY MORNING. DURING THE AFTERNOON MODEL X-SECTIONS AND SOUNDINGS SHOW MOIST E-NELY UPSLOPE FLOW DEEPENING ON THE PLAINS WITH PRECIPITABLE WATER VALUES RISING FM ABOUT A HALF INCH IN THE MORNING TO AROUND AN INCH BY 00Z/WED...TO AROUND 1.25 INCH DURING THE EVENING. MEANWHILE AT THE SAME TIME SLY MID-LEVEL FLOW IN ADVANCE OF THE TROUGH TRANSPORTS A NARROW PLUME OF SUBTROPICAL MOISTURE UP FM NEW MEXICO AND OVER ERN PORTIONS OF COLORADO FURTHER MOISTENING THE COLUMN OVER THE AREA. BY 00Z/WED NAM INDICATES SFC BASED CAPES OVER 2000 J/KG IN THE VICINITY OF WHAT APPEARS TO BE A STALLED SFC FRONTAL BNDRY SITTING ALONG THE SPINE OF THE PALMER DIVIDE. QPF FIELDS OFF THE NAM AND GFS INDICATE A BULLS EYE OF 2-4 INCH RAINFALL 3-HR TOTALS TUESDAY EVENING WITHIN A ZONE OF STG LOW-LEVEL CONVERGENCE AND SHEAR ALONG THE FRONT...CENTERED AROUND THE LIMON AREA. PAST COUPLE MODEL RUNS HAVE INDICATED A SIMILAR QPF PATTERN. MINOR IMPULSES TRANSLATING ALONG THE BOTTOM OF THE MAIN TROUGH ARE LIKELY TO PRODUCE CONVECTION IN OTHER PARTS OF THE CWFA THROUGH THE NIGHT. AFTER MIDNIGHT WITH ALL OF THE MOISTURE AND OUTFLOW BNDRYS FLOATING AROUND PRETTY GOOD BET WE/LL SEE SOME LOCALLY DENSE FOG ON THE PLAINS. WHILE ALL THIS IS GOING ON...MTN AREAS INCLUDING THE WRN VALLEYS SHOULD ESCAPE WITH LITTLE MORE THAN ISOLATED TO WIDELY SCATTERED AFTN AND EVE -SHRA/-TSTMS ALONG WITH NOT MUCH COOLING. BY WEDNESDAY...AMBIENT HIGH PLAINS AIRMASS REMAINS RELATIVELY COOL AND MOIST WITH GENERAL TROUGHING OVER THE REGION AND WEAK LOW-LEVEL UPSLOPE FLOW EAST OF THE MTNS. LOOKING FOR MAX TEMPS ON THE PLAINS TO BE AS MUCH AS 12-15F BELOW AVERAGE. AVG HIGH AT DENVER AT THIS TIME IS 87F. ATMOSPHERE LOOKS A BIT MORE STABLE OUT ACROSS THE PLAINS...SO RAIN CHANCES EXPECTED TO DROP OFF OUT THERE. CLOSER IN TO THE FRONT RANGE MONSOONAL MOISTURE STILL IN PLACE AND WITH DIABATIC HEATING SHOULD SEE RE-DEVELOPMENT OF SHWRS AND STORMS BY AFTERNOON. LIGHTER FLOW MAY PRODUCE A FEW HVY RAIN MAKERS IN AND NEAR THE FTHLS LATE IN THE DAY. BY THURSDAY...SHORTWAVE TROUGH MOVES OUT MAKING WAY FOR AN UPPER RIDGE TO BUILD IN THE FM 4-CORNERS REGION. WARMING BEGINS ALOFT INITIALLY EVENTUALLY MIXING DOWN TO THE GROUND THRU THE DAY. SHOULD SEE AFTERNOON TEMPS RETURNING TO THE LOWER 80S ON THE PLAINS. FRIDAY AND BEYOND...MEDIUM RANGE MODELS SHOW RESUMPTION OF THE MONSOON MOISTURE PLUME COMING UP FM NRN MEXICO BENEATH THE UPPER RIDGE SITTING OVER THE REGION. AS A RESULT SHOULD SEE AN INCREASED CHANCE FOR SOAKING RAINFALL FROM WARM CORE CONVECTION. LOOKING FOR TEMPS TO BE NEAR OR SLIGHTLY ABOVE NORMAL DURING THE PERIOD. && .AVIATION...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE IN THE LATE AFTERNOON AND EVENING AND INSTRUMENT APPROACHES TO KDEN WILL LIKELY BE NEEDED. THERE MAY BE SOME LOCALIZED IFR CEILINGS/VISIBILITIES IN THE RAIN THIS EVENING. SHOWERS WILL DIMINISH AFTER MIDNIGHT BUT LOW CEILINGS WILL LIKELY PERSIST INTO TUESDAY MORNING. EXPECT CEILINGS TO IMPROVE AFTER 15Z WITH VFR CONDITIONS PREVAILING THROUGH MONDAY. && .BOU WATCHES/WARNINGS/ADVISORIES...TORNADO WATCH FOR LARIMER...WELD...LOGAN AND MORGAN COUNTIES UNTIL 8 PM MDT TONIGHT.

THE PLAINS WILL REMAIN MAINLY STABLE UNDER A CAP THROUGH 3 PM AT LEAST UNTIL AN UPPER TROUGH CURRENTLY OVER UTAH MOVES CLOSER. SOME OF THE STORMS ON THE PLAINS WILL BE ABLE TO PRODUCE LARGE HAIL UP TO GOLF BALL SIZE AND WIND GUSTS UP TO 60 MPH. THERE IS A POSSIBILITY THAT STORMS NEAR THE WYOMING BORDER WILL BE ABLE TO PRODUCE AN ISOLATED TORNADO. THE STORMS OVER THE PLAINS THIS EVENING WILL HAVE A THREAT OF HEAVY RAINFALL OF UP TO TWO INCHES IN AN HOUR. THUNDERSTORMS WILL END OVER THE MOUNTAINS DURING THE EVENING...THEN SLOWLY DIMINISH FROM WEST TO EAST OVER THE PLAINS AFTER MIDNIGHT. SOME STORMS WILL BE ABLE TO LAST INTO THE EARLY MORNING HOURS OVER THE PLAINS AS AN UPPER TROUGH AXIS PASSES OVER NORTHEASTERN COLORADO TOMORROW MORNING. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY BY MONDAY DRIER AND WARMER AIR WILL SPREAD EASTWARD ACROSS THE OUTLOOK AREA AS A WEAK HIGH PRESSURE RIDGE PASSES OVER THE REGION. ON TUESDAY...YET ANOTHER UPPER AIR WEATHER DISTURBANCE ACCOMPANIED BY A RATHER STRONG COLD FRONT WILL SWING OUT OF THE PACIFIC NORTHWEST AND OVER NORTHERN COLORADO.
