The radar
The Quad Cities radar (KDVN), 91 km from the middle of the area, began a volume at 03:03 UTC, the scan nearest the moment this went out.

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 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.
The nearest sounding before it
Davenport, (KDVN), launched 00:00Z, 3.0 hours before the alert went out and 88 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.

NICHOLSWhat 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 Quad Cities, IA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 17, 6:34 PM CDT, 3 hours 28 minutes earlier.
Area forecast discussion, Jun 17, 6:34 PM CDT, 3 hours 28 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
634 PM CDT TUE JUN 17 2014
.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 227 PM CDT TUE JUN 17 2014
THE MAIN FORECAST ISSUE IN THE SHORT TERM PERIOD IS CONVECTIVE
TRENDS/COVERAGE/SEVERITY TONIGHT INTO WEDNESDAY.
IN THE NEAR TERM...STRONG WARM AIR ADVECTION HAS BECOME RE-ESTABLISHED
ACROSS THE FORECAST AREA. SPC IS MONITOR ENHANCED CU FIELD ACROSS
EASTERN FRINGES OF THE FORECAST AREA FOR A POSSIBLE WATCH...PER
LATEST SWOMCD. ANY DEVELOPMENT WOULD LIKELY PUSH EAST QUICKLY.
OTHERWISE...INGREDIENTS APPEAR TO BE COMING TOGETHER FOR AT LEAST ONE
ROUND OF SEVERE STORMS/HEAVY RAIN TONIGHT INTO WEDNESDAY MORNING.
CONFIDENCE IS STILL RATHER LOW IN HANGING MY HAT ON ANY PARTICULAR
SOLUTION...ALTHOUGH RIGHT NOW...TEND TO FAVOR THE HI-RES ARW/NMM
SOLUTIONS...WHICH PUSH AN MCS SOUTHWARD THROUGH THE AREA TONIGHT.
HOWEVER...CANNOT DISCOUNT THE RAP/HRRR FAMILY...WHICH DEVELOPS
DISCRETE SUPERCELLS BY EARLY EVENING AND BRUSHES THE NORTHERN
FRINGES OF THE CWA. STORMS EARLY ON WOULD LIKELY POSE A THREAT FOR
ALL TYPES OF SEVERE WEATHER...INCLUDING TORNADOES.
EVENTUALLY...STORM MERGERS AND BOWING SEGMENTS SHOULD FAVOR
STRAIGHT LINE WINDS.
IN TERMS OF HEAVY RAIN/FLASH FLOOD POTENTIAL...NORTHERN COUNTIES
RECEIVED WIDESPREAD 2-3...LOCALLY 4 INCHES OF RAIN OVERNIGHT AND
ARE THE MOST PRIMED FOR FLASH FLOODING. WILL ISSUE A FLASH
FLOOD WATCH FOR THESE AREAS. THE SPC WRF SUPPORTS ADDITIONAL
THUNDERSTORM COMPLEXES OVERNIGHT...OVER MOST IF NOT ALL OF THE
FORECAST AREA. HAVE OPTED TO RUN THE FLASH FLOOD WATCH ONLY UNTIL
NOON...AS LATER SHIFTS REEVALUATE AND UPDATE THE TIMING/COVERAGE.
LOOKING AHEAD TO WEDNESDAY AFTERNOON...MODELS INDICATE LESS
CAPPING AND MORE POTENTIAL FOR EARLIER CONVECTION/SEVERE STORMS.
CENTRAL AND SOUTHERN PORTIONS OF THE FORECAST AREA WOULD BE
FAVORED FOR HIGHER STORM COVERAGE.
.LONG TERM...(WEDNESDAY NIGHT THROUGH NEXT TUESDAY)
ISSUED AT 227 PM CDT TUE JUN 17 2014
WEDNESDAY NIGHT THROUGH FRIDAY...BULK OF 12Z RUN MODELS SUGGEST
SHARPENING OF UPPER RIDGE ACRS THE UPPER MS RVR VALLEY INTO THE
WESTERN GRT LKS WED NIGHT...WITH CYCLONIC FLOW AND EMBEDDED WAVE
SPRAWLING OUT ACRS THE MID AND UPPER PLAINS. THIS WOULD GENERALLY
SUGGEST THE DVN CWA UNDER THE AXIS OF THIS FEATURE MAY BE IN
BETWEEN THE MAIN WED NIGHT CONVECTIVE REGIONS OF THE PLAINS INTO
MN...AND THE NORTHERN OH RVR VALLEY/SOUTHERN GRT LKS. BUT
TIGHTENING NORTHWEST-TO-SOUTHEAST ORIENTED LLVL BOUNDARY POSSIBLY
EXTENDING FROM NW IA INTO THE EAST CENTRAL CWA...PLUS ANY OTHER OUT
FLOW BOUNDARIES FROM EARLIER CONVECTIVE SYSTEMS SHOULD BE THE FOCUS
OF RENEWED CONVECTION AND EVENTUAL MCS/S THIS PERIOD. ACCEPTED MCS
FORCING TOOLS OF THE NAM80 AND UKMET SUGGEST A MCS GENERATION ZONE
FROM NEB INTO SW IA...AND ANOTHER ACRS THE NORTHEASTERN HALF TO
THIRD OF THE DVN CWA INTO WI AND NORTHEASTERN IL WED EVENING INTO
THE OVERNIGHT/EARLY THU MORNING. SHEAR PROFILES AND THTA-E FEED ALL
SUPPORT THE POTENTIAL OF SVR STORMS AND VERY HEAVY RAIN IN ANY
STORM CLUSTERS OR MCS/S THAT CAN DEVELOP OR PROPAGATES INTO THE AREA
AND WILL MAINTAIN HIGH CHC TO LIKELY POPS WED NIGHT. BUT COULD ALSO
SEE THE POTENTIAL THAT AFTER THE EARLY EVENING ACTIVITY DIES DOWN...
MOST OF THE OVERNIGHT CONVECTION OCCURS OFF TO THE WEST AND
NORTHWEST/DAKOTAS AND NEB/...AND WI INTO NORTHEASTERN IL. LOWS
UPPER 60S INTO THE LOWER 70S. THU...THE SAME CONVECTIVE GAME
CONTINUES OF WHAT LINGERING OUTFLOW BOUNDARY/S FROM WED NIGHT...OR
THE MAIN WARM FRONT ITSELF TRYING TO RETREAT NORTHWARD AHEAD OF
NORTHEASTERN PLAINS WAVE TO ACT AS AFTERNOON AND EVENING FOCAL
POINTS FOR NEW CONVECTIVE INITIATION TO OCCUR. COULD SEE THE IDEA OF
AFTER MORNING CONVECTIVE DEBRIS CLEARS...MAIN WARM FRONT RETREATS
ACRS THE FAR NORTHERN CWA FOR A MAINLY DRY AND WARMING DAY UNTIL
LATE AFTERNOON AGAIN WHEN CONVECTION BLOSSOMS IN THE NORTHERN CWA IN
VCNTY OF THE WARM FRONT...AS WELL AS WESTERN INTO CENTRAL IA AHEAD
OF A TYPE OF NORTH-TO SOUTH ORIENTED BOUNDARY AND UNDER THE FORCING
OF CYCLONIC WAVE ALOFT ENCROACHING ON WESTERN IA. IF THIS OCCURS AND
TEMPS WARM TO NEAR 90 DEGREES WITH LOWER 70 DPTS...AMBIENT CAPES OF
3-4K+ J/KG COULD BUILD UP TO FUEL YET ANOTHER SEVERE MCS EVENT THU
NIGHT ACRS PORTIONS OF THE CWA. MOST OF THE CWA WORTHY OF HIGHER POPS
THU NIGHT IF UPSTREAM FRONT MAKES AN ADEQUATE PUSH EASTWARD AND T-
BONES THE WARM FRONT INDUCED CONVECTION TRYING TO PUSH NORTHWARD.
COMPOUNDED HEAVY RAIN EVENTS COULD MAKE FOR WIDESPREAD FLASH
FLOODING ESPECIALLY NORTH OF I80 THU NIGHT INTO FRI MORNING.
HOPEFULLY PROGRESSION OF UPPER WAVE ACRS THE UPPER MS RVR VALLEY
WILL MAKE FOR A CONVECTIVE LULL PERIOD FRI AFTERNOON AND NIGHT AFTER
ANY MORNING LINGERING STORM CLUSTERS CLEAR OFF TO THE EAST.
AFTERNOON FRI TEMP RECOVERY BACK INTO THE MID TO UPPER 80S BUT
HOPEFULLY UNDER WAKE RIDGING FOR NO RENEWED SHOWERS/STORMS FRI
EVENING.
SATURDAY THROUGH NEXT TUESDAY...00Z RUN MEDIUM RANGE SOLUTIONS/MREFS
SUGGEST BROAD UPPER RIDGING FROM THE ROCKIES TO THE EASTERN OH RVR
VALLEY...WITH RIDGE-RIDING VORTS IGNITING OCCASIONAL STORM CLUSTERS
GENERALLY FROM THE NW HIGH PLAINS...EASTWARD TO THE GRT LKS INTO
THE WEST CENTRAL APPALACHIANS. BUT ALSO SIGNS OF A SECONDARY WEST-TO-
EAST ORIENTED LLVL BAROCLINIC ZONE FROM NEB/KS ACRS MO/SOUTHERN IA
INTO IL. THUS CANNOT RULE OUT MORE STORMS IMPACTING PARTS/ESPECIALLY
THE SOUTH HALF/OF THE CWA FROM LATE SAT INTO SUNDAY...AND CHC POPS
WILL HAVE TO BE MAINTAINED. WILL ADVERTISE HIGHS NEAR OR SLIGHTLY
ABOVE NORMAL THROUGH THE WEEKEND. LONGER RANGE INDICATIONS SUGGEST A
L/W TROF SHEARING DOWN IN THE NORTHERLIES ACRS THE UPPER MIDWEST TO
WESTERN GRT LKS MON THOUGH TUE. THIS COULD RESULT IN MUCH COOLER
TEMPS ASSOCIATED WITH A BACKDOOR GRT LKS HIGH BY LATE TUE OR NEXT
WED...BUT MORE SHOWERS AND STORMS POSSIBLE IN THE TRANSITION LATE
SUNDAY INTO MON. ..12..

BY LATE EVENING...THE THREAT WILL TRANSITION TO MAINLY DAMAGING STRAIGHT LINE WINDS. HEAVY RAIN IS ALSO POSSIBLE TONIGHT INTO WEDNESDAY MORNING. A FLASH FLOOD WATCH IS IN EFFECT FOR AREAS NORTH OF U.S. HIGHWAY 30...WHICH RECEIVED RECENT HEAVY RAINFALL THAT HAS RESULTED IN SATURATED SOIL CONDITIONS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY VERY WARM AND HUMID CONDITIONS WILL BE SEEN ACROSS THE AREA ON WEDNESDAY. HEAT INDEX READINGS ARE EXPECTED TO BE WELL INTO THE 90S TO NEAR 100 DEGREES. AN ACTIVE WEATHER PATTERN WILL BE SEEN ACROSS THE AREA WEDNESDAY THROUGH MONDAY. THERE IS A DAILY CHANCE OF THUNDERSTORMS FROM WEDNESDAY THROUGH SUNDAY. THE STORM PREDICTION CENTER HAS A SLIGHT RISK OF SEVERE STORMS FOR THE ENTIRE AREA ON WEDNESDAY. THE PRIMARY THREATS CURRENTLY LOOK TO BE DAMAGING WINDS AND LARGE HAIL. FOR THE THURSDAY THROUGH SUNDAY TIME FRAME...IT IS TOO EARLY TO DETERMINE THE RISK OF SEVERE STORMS. .SPOTTER INFORMATION STATEMENT...
