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.

GIMMESTADWhat forecasters said that day
The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 15, 2:20 PM MDT, 5 hours 39 minutes earlier.
Area forecast discussion, Jun 15, 2:20 PM MDT, 5 hours 39 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 220 PM MDT TUE JUN 15 2004 .SHORT TERM DISCUSSION...THINGS ARE COMING TOGETHER FOR A SIGNIFICANT PRECIPITATION EVENT OVER THE NORTHEAST PLAINS OF COLORADO...AS WELL AS SEVERE WEATHER. CURRENT ANALYSIS SHOWS A WELL DEFINED BOUNDARY EXTENDING FROM MONUMENT HILL NORTHEASTWARD TO NEAR FORT MORGAN AND STERLING. EXPECT CONVECTION TO EXPLODE SOON ALONG THIS BOUNDARY AS WE REACH CONVECTIVE TEMPERATURE AND ARE ABLE TO RELEASE THE CAPES OVER 3000 J/KG ALONG AND EAST OF THE BOUNDARY. FARTHER WEST...THERE IS STILL SOME POTENTIAL FOR SEVERE AS CAPES ARE NEAR 1000 J/KG AND BOUNDARY MAY GET ENOUGH OF A PUSH FROM DEVELOPING CONVECTION TO BRING IT BACK TO THE FOOTHILLS. WILL MAINTAIN THE SCATTERED POPS ALONG THE FRONT RANGE AND HAVE ALREADY BOOSTED THEM TO LIKELY FARTHER EAST WHERE MCS INITIATION SHOULD TAKE PLACE. WEAK WAVE CURRENTLY MOVING NORTHWARD OUT OF NEW MEXICO SHOULD ALSO HELP GENERATE MORE WIDESPREAD PRECIP. COLD FRONT WILL PUSH IN AFTER MIDNIGHT AND WITH AMPLE LOW LEVEL MOISTURE WIDESPREAD STRATUS EXPECTED TO DEVELOP. WILL MAINTAIN SOME SMALL POPS INTO WEDNESDAY MORNING WITH WEAK UPSLOPE COMPONENT. BY WEDNESDAY AFTERNOON...EXPECT ANOTHER ROUND OF CONVECTION BUT THIS TIME MOST OF IT WILL BE CONFINED TO THE MOUNTAINS WHERE THE AIRMASS IS UNSTABLE ENOUGH. A COUPLE STORMS MAY DRIFT OFF THE FOOTHILLS INTO THE I-25 CORRIDOR BUT OTHERWISE THE PLAINS ARE FAR TOO STABLE TO SUPPORT THUNDER. WILL PLAY TEMPS MUCH COLDER WITH STRATUS AND CLOSE TO ETA GUIDANCE. .LONG TERM DISCUSSION...MODELS ARE STILL SHOWING STRONG RIDGING ALONG THE WEST COAST AND TROFING OVER THE CENTRAL U.S. THROUGH THE EXTENDED PERIOD. 500-300 MB FLOW OVER THE AREA REMAINS PRETTY MUCH ZONAL THROUGH SUNDAY THEN BECOMES NWLY AS A RIDGE BEGINS BUILDING OVER THE SRN ROCKIES. THE GFS IS NO LONGER DIGGING THE UPR TROF AS FAR SOUTH AS IT DID YESTERDAY. MODELS ALSO DELAYING THE ARRIVAL OF A LATE WEEK COLD FRONT IN NERN COLORADO. A STRONG COLD FRONT WAS PROGGED TO BACKDOOR INTO NERN COLORADO AROUND 12Z/FRIDAY. NOW LATEST ETA/AVN SHOW ITS ARRIVAL NOT UNTIL LATE FRIDAY AFTERNOON OR EARLY EVENING. ETA/AVN ALSO NO LONGER SHOWING DOWNSLOPE WARMING AND DRYING ON THURSDAY...INSTEAD THEY KEEP THE PLAINS UNSEASONABLY COOL AND MOIST WITH PERSISTENT UPSLOPE FLOW ALBEIT SHALLOW THROUGH MUCH OF THE DAY THURSDAY. THUS CONDITIONS NOW LOOK TOO STABLE FOR CONVECTIVE INITIATION EAST OF THE MTNS. ON THE OVERHAND...THE ELEVATED HEAT SOURCE OF THE MTNS AND FOOTHILLS SHOULD SEE AT LEAST ISOLATED AFTERNOON AND EARLY EVENING T-STORMS THURSDAY WITH A 850-700MB THETA-E RIDGE UP AGAINST THE FRONT RANGE. FRIDAY...ETA SHOWS S/SWLY FLOW FLUSHING THE COOL/MOIST AIR ON THE PLAINS EAST ON THE AREA IN THE MORNING...THEN PRESSURE FALLS ALONG THE FRONT RANGE TURN WINDS AROUND TO NELY IN THE AFTERNOON. ETA SHOWS CAPE VALUES IN THE 1200-1800 J/KG RANGE AND BOUNDARY LYR HELICITY VALUES IN THE 200-300 RANGE WITH 700-600MB 30-35KT W/SWLYS AND 20KT SELYS AT THE SFC. FRIDAY AFTERNOON AND NOT THURSDAY LOOKS TO BE THE NEXT SVR WX THREAT FOR THE PLAINS. COULD SEE ISOLATED SVR T-STORMS UP ALONG THE FRONT RANGE WITH A DENVER CYCLONE IN PLACE. SATURDAY-TUESDAY...AVN SHOWS A REINFORCING SURGE OF COOL/MOIST AIR EAST OF THE MTNS ON SATURDAY AS A COLD CORE 1023MB SFC HIGH SLIDES SEWRD OUT OF MONTANA. MOS GUIDANCE MAX TEMPS IN THE LOWER 70S ON THE PLAINS SATURDAY MAY BE TOO WARM SHOULD UPSLOPE CLOUDINESS BE GREATER AND THE SFC HIGH BE STRONGER THAN EXPECTED. MAY NOT SEE HIGH PLAINS TEMPS CLIMBING ABOVE THE LOWER 60S. AGAIN...AIRMASS ON THE PLAINS WILL PROBABLY BE TOO COOL AND STABLE FOR T-STORM FORMATION BUT SCATTERED LIGHT STRATIFORM PRECIP A GOOD BET. SUNDAY...SEE ONLY SLIGHT WARMING WITH COOL HIGH PRESSURE AIR HANGING AROUND...BUT LESS CLOUD COVER. 10 PCT POPS ALREADY IN THE FCST FOR SUNDAY AFTERNOON AND EVENING MAY BE TOO HIGH...BUT WILL LEAVE POPS ALONE. MONDAY... GFS HINTS AT ANOTHER WEAK SURGE OF COOL HIGH PRES AIR AND LOW LEVEL UPSLOPE FLOW. THOUGH UPSLOPE WILL BE SHALLOW/WEAK...WILL KEEP A SLIGHT CHANCE OF T-SHOWERS IN FOR MONDAY. TUESDAY LOOKS DRY AND WARMER WITH UPR RIDGE BUILDING OVER THE SRN ROCKIES. && .BOU WATCHES/WARNINGS/ADVISORIES...NONE. BARJENBRUCH/BAKER

HOWEVER ENOUGH MOISTURE WILL BE AVAILABLE FOR AT LEAST A SLIGHT CHANCE OF SHOWERS EACH DAY. IN THE MOUNTAINS AND FOOTHILLS...EXPECTED ISOLATED AFTERNOON AND EVENING THUNDERSTORMS EACH DAY WHERE THE ATMOSPHERE SHOULD REMAIN RELATIVELY WARM AND UNSTABLE. GUSTY WINDS AND LIGHTNING WILL BE THE MAIN THREAT FROM THESE STORMS. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION HAS ALREADY OCCURRED. BARJENBRUCH/BAKER
