The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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.
The nearest sounding before it
Grand Junction, CO (KGJT), launched 12:00Z, 9.0 hours before the alert went out and 117 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1256 PM MDT THU JUN 11 2015
.UPDATE...
ISSUED AT 1256 PM MDT THU JUN 11 2015
WE HAVE EXPANDED THE FLASH FLOOD WATCH TO INCLUDE THE COLORADO
TAVAPUTS PLATEAU...THE FLATTOPS RANGE AND AREAS SOUTH TO THE
PREVIOUS WATCH AREA. ALSO HAVE EXTENDED THE FLASH FLOOD WATCH FOR
THE FAR SOUTHERN ZONES UNTIL MIDNIGHT FRIDAY NIGHT. THIS IS
PROMPTED BY STEADY RAIN THAT HAS BEEN CENTERED ALONG THE TAVAPUTS
PLATEAU EASTWARD INTO THE FLATTOPS THROUGH MOST OF THE DAY SO FAR.
ALSO THUNDERSTORMS HAVE DEVELOPED WITH HEAVY RAIN AND SOME
FLOODING REPORTED. THE UPPER TROUGH IS JUST UPSTREAM AND WILL MOVE
OVER THE FORECAST THIS AFTERNOON/EARLY EVENING PROVIDING
INCREASED INSTABILITY AND DYNAMICS. THEREFORE ADDITIONAL HEAVY
RAIN IS EXPECTED TO CONTINUE FOR THE NEXT SEVERAL HOURS. FOR THE
SOUTHERN EDGE...SINCE RIVERS ARE RUNNING SO HIGH WITH VARIOUS
FLOOD WARNINGS/ADVISORIES ALREADY OUT...PROBLEMS WILL CONTINUE AS
ADDITIONAL RAINFALL IS EXPECTED THROUGH FRIDAY EVENING.
IN ADDITION TO FLOOD POTENTIAL...HAIL HAS BEEN REPORTED FROM SOME
OF THE THUNDERSTORMS OVER OUR SOUTHERN ZONES. ONE REPORT WAS OF
QUARTER SIZED HAIL NEAR DURANGO...BUT EXPECT MOST HAIL WILL BE
LESS THAN ONE INCH IN DIAMETER.
&&
.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 247 AM MDT THU JUN 11 2015
THE DEEP TROPICAL MOISTURE WILL CONTINUE OVER THE REGION THROUGH
FRIDAY.
TODAY...THE UPPER LOW WORKS TO THE FOUR CORNERS. AN AREA OF WEAK
SHEARED DYNAMICS DEVELOPS BY LATE MORNING BROADLY CENTERED OVER THE
CENTRAL CWA THAT THEN SHIFTS SE TOWARDS PAGOSA SPRINGS THROUGH THE
AFTERNOON. THE SE CWA WILL HAVE SOME MID LEVEL DRYING AHEAD OF THE
PROGRESSING LOW. THIS ALONG WITH SOME WEAK COLD ADVECTION ALOFT
STEEPENS AFTERNOON LAPSE RATES TO OVER 7.5 C/KM. THE SHEARED
ENVIRONMENT IS NOT IDEAL BUT THE STRONG CYCLONIC FLOW WILL HELP TO
ORGANIZE CONVECTION. WBZ LEVEL IS AROUND 13KFT BUT SOME HAIL WILL BE
POSSIBLE WITH ORGANIZED STORMS. IN SPITE OF SOME DRYING ACROSS THE
SOUTH...FLOODING CONCERNS CONTINUE. EVEN MODERATE RAINFALL CAN
CREATE RUNOFF ISSUES AND THE SOUTHERN RESERVOIRS ARE NEAR DAM FULL AND
ORGANIZED STORMS WILL BE MOVING SLOWER THAN THE 0-6KM MEAN FLOW.
IN THE NORTHERN FORECAST AREA...THE DEEP MOISTURE...NEAR 1.0 PW...
REMAINS IN PLACE FOR WIDESPREAD SHOWERS. SOILS ACROSS THE NORTH
ARE NOT AS WET AS SOUTHERN AREAS SO FLOODING PROBABILITIES ARE LOW
THERE AND WILL KEEP THEM OUT OF THE FLOOD WATCH. LESS INSTABILITY
WILL LIMIT CONVECTIVE POTENTIAL.
TONIGHT AS THE LOW WORKS ACROSS THE SOUTHERN CWA SHOWERS WILL
CONTINUE TO AROUND MIDNIGHT THEN DIMINISH TOWARDS MORNING. SHEAR
WEAKENS AND LAPSE RATES SLACKEN SO STORMS WILL WEAKEN.
FRIDAY...THE UPPER LOW DROPS ONTO THE PLAINS AND LEAVES THE CWA IN
NE FLOW. THIS SHIFTS THE DEEPER MOISTURE AGAIN TO THE SOUTHERN CWA.
STORMS WILL FAVOR THE SOUTHERN MTNS AND BE MORE DIURNALLY DRIVEN.
FLOOD CONCERNS CONTINUE.
COOLER TEMPERATURES ON THURSDAY REBOUND TO NEAR NORMAL ON FRIDAY.
.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 247 AM MDT THU JUN 11 2015
THE CLOSED LOW THAT BROUGHT ALL THE PRECIP ON THURSDAY WILL
REMAIN FAIRLY STATIONARY FRIDAY NIGHT BEFORE OPENING UP AND
GETTING ABSORBED IN A MORE ELONGATED TROUGH FRIDAY EVENING INTO
FRIDAY NIGHT. WHILE MOISTURE DOES DECREASE...PLENTY WILL STILL
REMAIN IN THE ATMOSPHERE TO ALLOW FOR AFTERNOON SHOWERS AND STORMS
SATURDAY AFTERNOON THANKS IN LARGE PART TO SAID TROUGH. AS THE
TROUGH SHIFTS EAST...UPPER LEVEL SUPPORT WANES SOMEWHAT SUNDAY
CAUSING A DECREASE IN CONVECTION. THIS WILL BE SHORT-LIVED AS
ACTIVITY PICKS UP AGAIN MONDAY AS A SHORTWAVE MOVES OVERHEAD AND
PERSISTS INTO TUESDAY ALLOWING MORE AFTN CONVECTION. A DOWNTURN IN
CONVECTION IS EXPECTED WEDNESDAY AND BEYOND.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 1057 AM MDT THU JUN 11 2015
ABUNDANT MOISTURE AND INSTABILITY WILL LEAD TO WIDESPREAD SHOWERS
AND THUNDERSTORMS OVER EASTERN UTAH AND WESTERN COLORADO THROUGH
THIS AFTERNOON AND EVENING. TERMINAL FORECASTS WILL BE IMPACTED
BY THIS WEATHER BY LOWERED FLIGHT CRITERIA DUE TO MODERATE TO
HEAVY RAINFALL RATES IMPACTING VISIBILITY AND DROPPING CIGS TO
MVFR LEVELS. KTEX AND KDRO ALSO STAND THE BETTER CHANCES OF SEEING
STRONG OR ERRATIC OUTFLOW WINDS FROM PASSING STORMS. AS STORM
INTENSITY AND COVERAGE DECLINES THROUGH THE OVERNIGHT HOURS
GENERAL IMPROVEMENT IS EXPECTED. HOWEVER IMPACTS FROM LOCALIZED
FOG MAY DEVELOP FROM THE RECENT RAINFALL...HOWEVER CONFIDENCE IS
QUITE LOW ON THIS ATTM.
&&
.HYDROLOGY...
ISSUED AT 247 AM MDT THU JUN 11 2015
FLASH FLOOD WATCHES REMAIN IN EFFECT FOR SE UTAH AND SW COLORADO.
DRY WASHES AND SLOT CANYONS WILL BE SUSCEPTIBLE TO FLOODING FROM
THE MASSIVE INFLUX OF MOISTURE FROM THE REMNANTS OF TROPICAL STORM
BLANCA THROUGH THIS EVENING. MANY RIVERS...CREEKS AND STREAMS IN
UTAH AND COLORADO ARE ALREADY RUNNING HIGH DUE TO SNOWMELT AND
RECENT RAINFALL. ADDITIONAL RAINFALL WILL INCREASE CHANCES FOR
FLASH FLOODING ACROSS THE AREA. SOME RIVER BANKS MAY ALSO BECOME
UNSTABLE. USE CAUTION IF WALKING OR RECREATING NEAR RIVERS OR
STREAMS AS WATER IS RUNNING FAST AND HIGH.
