The Des Moines radar (KDMX), 150 km from the middle of the area, began a volume at 22:14 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

Omaha, NE (KOAX), launched 12:00Z, 10.2 hours before the alert went out and 157 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.

What 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 Des Moines, IA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 1, 4:04 PM CDT, 1 hour 9 minutes earlier.

Area forecast discussion, Jun 1, 4:04 PM CDT, 1 hour 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
404 PM CDT SUN JUN 1 2014

.SHORT TERM /TONIGHT/...
ISSUED AT 345 PM CDT SUN JUN 1 2014

PRIMARY CONCERN THIS AFTERNOON WILL OBVIOUSLY BE CONVECTIVE TRENDS.
SEPARATE MCS CLUSTERS OVER NE AND SRN MN MERGED DURING THE AFTERNOON
ALONG 0-1KM CONVERGENCE AXIS IN ENVIRONMENT OF INCREASING MLCAPES...
2000 J/KG...AND REDUCED CINH. RELATIVELY DEEP THERMODYNAMICALLY
DOMINATE TORNADOES DEVELOPED DURING PEAK HEATING IN VERY WEAK SHEAR
ENVIRONMENT OVER NRN IA NEAR BOUNDARY WITH 0-3KM CAPES J/KG AT
TIMES.  ESSENTIALLY VERY STRONG LANDSPOUTS WITH ROTATION NOTED ABOVE
10K FT ON RADAR. SEVERE POTENTIAL AND ONGOING WIND THREAT IN THE
SIOUXLAND AREA SHOULD WEAKEN WITH TIME AS DEEP SHEAR DIMINISHES
QUICKLY FARTHER EAST...BUT ATTENTION TURNING TO FLASH FLOODING AS
NOTED BELOW.

.LONG TERM /MONDAY THROUGH SUNDAY/...
ISSUED AT 345 PM CDT SUN JUN 1 2014

FOR BEGINNING OF FORECAST PERIOD...ANTICIPATE OVERNIGHT CONVECTION
TO BE CONTINUING TO PUSH EASTWARD ACROSS CWA...WITH LINGERING
PRECIPITATION IN THE EAST. GIVEN AMOUNT OF MOISTURE PRESENT...MAY
CONTINUE TO SEE CHANCES FOR HEAVY RAIN...HOWEVER...GIVEN BEST
FORCING AND PRECIPITATION ANTICIPATED TO BE EAST OF THE
AREA...WILL ALLOW FLASH FLOOD WATCH TO EXPIRE AT 12Z...THOUGH WILL
NEED TO BE MONITORED BY NEXT SHIFT FOR POSSIBLE EXTENSION. WEAK
SURFACE HIGH WILL THEN PUSH SOUTH FOR MONDAY WHICH WILL BRING
COOLER TEMPERATURES...AND HAVE DROPPED LOWS A BIT MONDAY NIGHT
WITH HIGH PUSHING SOUTH...HOWEVER BREAK WILL BE SHORT LIVED AS
SECONDARY LOW PRESSURE SYSTEM BEGINS TO AFFECT THE REGION FOR
TUESDAY.

FORECAST FOR TUESDAY WILL BE THE MAIN CONCERN FOR THE
EXTENDED. SURFACE LOW WILL PUSH EASTWARD ACROSS CENTRAL PLAINS
WITH FRONTAL BOUNDARY EXTENDING INTO IOWA. HOWEVER...THERE IS
STILL A GOOD AMOUNT OF UNCERTAINTY IN MODEL SOLUTIONS AS TO
LOCATION OF THIS BOUNDARY AND TRACK OF THE LOW. LOCATION WILL BE
CRITICAL TO FORECAST. NAM IS CURRENTLY FURTHEST NORTH
SOLUTION...WITH OTHER MODELS ONLY SLIGHTLY FURTHER SOUTH.
HOWEVER...GFS IS SOUTH ENOUGH TO KEEP BEST SEVERE WEATHER THREAT
JUST SOUTH OF IOWA...HOWEVER THREAT SHOULD NOT BE DISCOUNTED GIVEN
PROXIMITY TO FRONT...ESPECIALLY IN SOUTHERN IOWA...AS WELL AS
SHEAR AND INSTABILITY PARAMETERS. SECONDARY CONCERN WITH SEVERE
THREAT WILL BE LOCATION OF INITIATION...DEPENDENT ON LOCATION OF
LOW. MODELS HAVE SLOWED PROGRESSION OF LOW SLIGHTLY...WITH CURRENT
RUNS SUGGESTION INITIATION WEST OF IOWA...INTO NEBRASKA OR KANSAS
CLOSER TO CENTER OF LOW. HOWEVER...COULD STILL SEE ENOUGH
INSTABILITY AHEAD OF SYSTEM INTO IOWA TO ALLOW FOR THUNDERSTORM
DEVELOPMENT IN AFTERNOON. HAVE THEREFORE KEPT POPS CONFINED TO
WEST IN AFTERNOON. WITH SLOWER SOLUTION...SEEMS BEST THREAT FOR
CENTRAL IOWA WILL BE MCS TRACKING ACROSS STATE OVERNIGHT. ONCE
AGAIN...SEVERE THREAT CANNOT BE RULED OVER EVEN WITH OVERNIGHT
PASSAGE AS SHEAR AND INSTABILITY REMAIN FAIRLY HIGH. ADDITIONAL
CONCERN WILL BE WITH HEAVY RAINFALL...AS MOISTURE TRANSPORT
REMAINS HIGH INTO CENTRAL IOWA AHEAD OF SYSTEM...AND PWAT VALUES
ARE EXPECTED TO BE NEAR 1.8...WHICH IS SEASONLY HIGH. ANTICIPATE
WIDESPREAD RAINFALL OVERNIGHT...AND HAVE SHIFTED SLIGHTLY FURTHER
SOUTH GIVEN MODELS MORE SOUTHERLY TREND...AND HAVE INCREASED POPS
AND QPF ACCORDINGLY.

BEYOND TUESDAY... WEAK RIDGE WILL BUILD IN AHEAD OF ANOTHER LOW
PRESSURE SYSTEM SET TO TRACK EASTWARD ACROSS CANADA. HAVE LOW
CONFIDENCE IN POPS FOR THURSDAY AND FRIDAY HEAD OF THIS
SYSTEM...THOUGH MAY SEE SCATTERED STORMS WITH ONLY WEAK HIGH
TRACKING NEAR GREAT LAKES...AND HAVE LEFT SLIGHT CHANCE POPS. BEST
CHANCES FOR ADDITIONAL PRECIPITATION WILL COME OVER THE WEEKEND
AS FRONTAL BOUNDARY ASSOCIATED WITH CANADIAN LOW PRESSURE SYSTEM
PUSHES INTO IOWA. TEMPERATURES WILL BE GENERALLY NEAR NORMAL
THROUGH REMAINDER OF EXTENDED...WITH HIGHS IN THE 70S AND LOWS IN
THE 50S AND 60S.

&&

.HYDROLOGY...
ISSUED AT 345 PM CDT SUN JUN 1 2014

AS MENTIONED ABOVE...EXPECT APPROACHING MCS TO WEAKEN SOMEWHAT
WITH TIME INTO THE NIGHT WITH LOSS OF DAYTIME HEATING...INCREASED
MLCINH...AND LACK OF DEEP SHEAR BUT MAINTAIN TO SOME EXTENT AS IT
ENTERS IA AND STRONG LOW LEVEL MOISTURE TRANSPORT AND ASSOCIATED
CONVERGENCE. PWS SHOULD PUSH TWO INCHES WITH WARM CLOUD DEPTHS TO
4KM AND NIL CORFIDI VECTORS...VERY FAVORABLE CONDITIONS FOR HEAVY
RAIN. HAVE ISSUED A FLASH FLOOD WATCH WHERE PREVIOUS HEAVY RAINS
FELL THIS AFTERNOON...BUT MAY HAVE TO BE EXPANDED SOUTHWARD
DEPENDING ON MCS TRENDS.

&&

.AVIATION...01/18Z
ISSUED AT 345 PM CDT SUN JUN 1 2014

EXPECT VFR CONDITIONS THROUGH THE NIGHT OUTSIDE OF THUNDERSTORM
TRENDS. HAVE THUNDER MENTIONED AT MORE LIKELY AREAS /KMCW/KFOD/ BUT
WILL STAY WITH VCSH AT OTHER LOCATIONS DUE TO REDUCED TIMING
CONFIDENCE...AVOIDING UNNECESSARY PROLONGED THUNDER MENTION.  THERE
IS ALSO THE POTENTIAL FOR MVFR OR LOWER FOG/STATUS OVERNIGHT...BUT
CONFIDENCE IS NOT GREAT ENOUGH TO INCLUDE AT THE MOMENT.
