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.

.SHORT TERM /TONIGHT/...
ISSUED AT 255 PM CDT THU JUN 11 2015

THUNDERSTORMS ARE DEVELOPING ACROSS SOUTHWEST IOWA AND SOUTHEAST
NEBRASKA AS ANTICIPATED...AND WILL MOVE NEARLY DUE EAST ACROSS
SOUTHERN IOWA THIS EVENING INTO TONIGHT. FURTHER NORTH...WIDESPREAD
LIGHT TO MODERATE SHOWERS WITH ISOLATED THUNDERSTORMS PERSIST WITHIN
THE REGION OF BROAD ASCENT AHEAD OF THE APPROACHING STORM SYSTEM.
HAVE MAINTAINED HIGH POPS ACROSS THE AREA...ESPECIALLY THROUGH

OUTLINED IN THE HYDROLOGY SECTION BELOW. THE COLD FRONT ASSOCIATED
WITH THE SYNOPTIC SYSTEM WILL PROGRESS SOUTHEASTWARD ACROSS THE
STATE OVERNIGHT...DROPPING TEMPERATURES PRETTY SHARPLY AFTER
MIDNIGHT BUT MAINTAINING THICK CLOUD COVER WHICH WILL MITIGATE THESE
FALLS SOMEWHAT.

.LONG TERM /FRIDAY THROUGH THURSDAY/...
ISSUED AT 255 PM CDT THU JUN 11 2015

AN ACTIVE PATTERN IS EXPECTED THROUGH THE WEEKEND AND INTO NEXT
WEEK WITH PERIODS OF SHOWERS AND THUNDERSTORMS. FLOODING WILL
CONTINUE TO BE A RISK AS ADDITIONAL RAINFALL SATURATES SOILS AND
RUNOFF INCREASES.

PRECIPITATION WILL BE EXITING EASTERN IOWA EARLY FRIDAY MORNING.
THIS WILL BE A BRIEF BREAK IN THE RAIN BEFORE ANOTHER SHORTWAVE
TROUGH LIFTS THROUGH THE PLAINS INTO THE MIDWEST FRIDAY INTO THE
WEEKEND BRINGING MORE CHANCES FOR PRECIPITATION.

FORECAST MODELS SUGGEST SURFACE BOUNDARY LINGERS NEXT WEEK WITH
ADDITIONAL SHORTWAVES MOVING THROUGH WESTERLY FLOW ALOFT. THIS
LIFT INTERACTING WITH A MOIST AIRMASS WITH PWATS OVER AN INCH
BRING CONTINUED CHANCES FOR RAIN.

.AVIATION...12/00Z
ISSUED AT 636 PM CDT THU JUN 11 2015

WIDESPREAD TSRA AND SHRA WILL CONTINUE TO TO AFFECT SITES THROUGH

.HYDROLOGY...
ISSUED AT 255 PM CDT THU JUN 11 2015

WIDESPREAD HEAVY RAINFALL HAS NOT MATERIALIZED...THUS THE FLASH
FLOOD WATCH HAS BEEN CANCELLED ACROSS NORTHERN AND MUCH OF CENTRAL
IOWA. HOWEVER...LOCALIZED HEAVY RAINFALL HAS FALLEN ACROSS SOUTHERN

THUNDERSTORMS ARE EXPECTED TO MOVE FROM SOUTHEASTERN NEBRASKA ACROSS
SOUTHERN IOWA FROM LATE THIS AFTERNOON INTO EARLY TONIGHT...CARRYING
A RISK FOR MORE LOCALLY HEAVY RAINFALL. THEREFORE...A FLASH FLOOD
WATCH WILL BE CONTINUED FOR SOUTHERN IOWA INTO TONIGHT...WITH THE
THREAT HEAVILY DEPENDENT ON THE DEVELOPMENT AND PROGRESSION OF THESE
STRONG THUNDERSTORMS. RFC DETERMINISTIC CONTINGENCY FORECASTS SHOW
SOME AREA RIVERS RISING INTO MINOR OR MODERATE FLOOD STAGE...PARTLY
AS A RESULT OF RAINS THAT HAVE ALREADY FALLEN AND PARTLY AS A RESULT
OF QPF FOR THE STORMS THIS EVENING INTO TONIGHT. AREAS PRIMARILY
IMPACTED AT THIS TIME WOULD SEEM TO INCLUDE THE LOWER RACCOON AND
DES MOINES BASINS AND POSSIBLY SOME SMALLER BASINS IN SOUTHERN IOWA.
