Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Omaha, NE (KOAX), launched 00:00Z, 9.6 hours before the alert went out and 153 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, Aug 9, 4:30 AM CDT, 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
430 AM CDT SUN AUG 9 2015

.SHORT TERM /TODAY/...
ISSUED AT 420 AM CDT SUN AUG 9 2015

EXPECT ONGOING PRECIPITATION ACROSS CWA ASSOCIATED WITH FORCING ON
NOSE OF LLJ TO PERSIST THROUGH THE MORNING HOURS. HEAVY RAINFALL
WILL REMAIN POSSIBLE WITH STORMS...AND MAY SEE TRAINING...ESPECIALLY
IN THE SOUTH AND WILL THEREFORE KEEP FLASH FLOOD WATCH AS IS FOR
NOW...THOUGH NORTHERN PORTIONS WILL BE LESS AT RISK FOR FLASH
FLOODING. IN ADDITION...CANNOT RULE OUT ISOLATED SEVERE POTENTIAL FOR
DAMAGING WINDS IN THE FAR SOUTHWEST THROUGH SUNRISE.

EXPECT SYSTEM TO HAVE GENERALLY PUSHES OUT OF CWA BY 18Z...THROUGH
COULD STILL SEE LINGERING PRECIPITATION IN THE FAR SOUTHEAST. CONCERN
WILL THEN SHIFT TO WAVE DROPPING INTO NORTHWESTERN IOWA LATE IN
PERIOD. MODELS ARE GENERALLY IN AGREEMENT WITH SLOWER SOLUTION...AND
HAVE TRENDED SLOWER...WITH ONLY SLIGHT POPS IN THE NORTHWEST AT THE
END OF THE PERIOD. HAVE BUMPED TEMPERATURES UP A FEW DEGREES GIVEN
THE AMOUNT OF WARMING YESTERDAY...HOWEVER CLOUD COVER COULD HELP
LIMIT TEMPS AND MAY BE TOO WARM.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
ISSUED AT 420 AM CDT SUN AUG 9 2015

CENTRAL IOWA SHOULD BE DRY TO START THE PERIOD HOWEVER THE NEXT
SYSTEM WILL ALREADY BE ON NORTHWEST IOWA DOOR STEP THIS EVENING.
A STRONG PV ANOMALY CURRENTLY OVER CENTRAL WYOMING...WILL MOVE
ACROSS THE STATE OVERNIGHT FOLLOWED BY ADDITIONAL SHORT WAVE
FRAGMENTS THROUGH MONDAY. THIS WILL BRING THE NEXT THREAT FOR
STORMS. THE PRIMARY ACTIVITY WILL BE OVER NORTHERN IOWA WITH
CHANCES DIMINISHING FURTHER TO THE SOUTH. SOME SEVERE WEATHER
POTENTIAL DOES EXIST MAINLY OVER THE NORTHWEST SUNDAY NIGHT. THE
UPPER RIDGE WILL INTENSIFY WILL REORGANIZE OVER THE WESTERN PLAINS
AS THE UPPER LEVEL ENERGY DIVES SOUTHEAST.

DRIER AIR WILL ARRIVE FROM NORTHWEST TO SOUTHEAST DURING THE DAY
MONDAY INTO MONDAY NIGHT AS HIGH PRESSURE SLIDES SOUTHEAST ALONG
THE EASTERN PERIPHERY OF THE HIGH PRESSURE SYSTEM. THIS SYSTEM
WILL KEEP THE AREA MAINLY DRY TUESDAY THROUGH THURSDAY FOLLOWED BY
LOW CHANCES FOR PRECIPITATION TO END THE PERIOD. THE PRIMARY
CHALLENGES FOR THE END OF THE PERIOD WILL BE THE EVOLUTION OF THE
PACIFIC NORTHWEST UPPER LOW TRACKING EAST AND SQUASHING THE UPPER
RIDGE. THE ECMWF REMAINS ABOUT 24 HOURS FASTER WITH THIS
PROGRESSION. TEMPERATURES THROUGH THE PERIOD WILL BE SEASON TO
SLIGHTLY ABOVE NORMAL.

&&

.AVIATION...09/06Z
ISSUED AT 1241 AM CDT SUN AUG 9 2015

DSM/OTM WILL SEE SOME HEAVY RAIN POTENTIAL THROUGH 12Z TODAY.
ANOTHER ROUND OF STORMS LOOKS TO MOVE IN B/T 08-10Z AND POSSIBLE
CAUSE BRIEF MVFR TO IFR VIS/CIGS. VFR AT MCW AND FOD FOR MUCH OF
THE TAF. ALO HAS THE POTENTIAL FOR SOME MVFR CIGS/VIS BUT CURRENT
RADAR TRENDS LOOK TO KEEP HEAVIEST CONVECTION TO ITS SOUTH. OTHER
CONCERN IS FOG DEVELOPMENT SUNDAY NIGHT AND HAVE MVFR VIS
MENTIONED FOR ALL TAF SITES TOWARDS THE END OF THE PERIOD.
