What happened
The episode as NWS DMX wrote it up.
A moist and unstable airmass was in place over Iowa. Elevated CAPE was around 2000 J/kg with downdraft CAPE around 1000 J/kg. The atmosphere was strongly sheared with 45 to 60 kts of shear available. Deep moisture was also in place with precipitable water values around 1.6 inches. A large MCS developed over Minnesota during the night. The MCS advanced slowly south into Iowa during the early morning hours. The outflow boundary from the MCS advanced well ahead of the storms themselves. It produced a 58 MPH wind gust as it passed the Estherville Airport. Heavy rain occurred with the storms with an inch of rain falling in 30 minutes in Estherville.

Area forecast discussion, Jun 21, 11:14 PM CST, 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 1214 AM CDT SAT JUN 22 2013 .SHORT TERM.../TONIGHT /... ISSUED AT 407 PM CDT FRI JUN 21 2013 FORECAST FOR TONIGHT IS DOMINATED BY POTENTIAL FOR THUNDERSTORMS AND ASSOCIATED EFFECTS. CURRENTLY A COMPLEX OF THUNDERSTORMS IS DEVELOPING ACROSS EASTERN SOUTH DAKOTA AND MOVING STEADILY EASTWARD. MOST SHORT TERM MODELS HAVE HANDLED CONVECTION POORLY TODAY AND ARE DIFFICULT TO TRUST FOR TONIGHT. HOWEVER...CONCEPTUAL MODELS WOULD DICTATE THAT WITH A FLATTENING MID LEVEL RIDGE OVERHEAD AND A CORRIDOR OF INSTABILITY LEADING EAST SOUTHEAST FROM THE STORM COMPLEX...IT SHOULD CONTINUE TO MOVE EASTWARD ACROSS SOUTHERN MINNESOTA EARLY TONIGHT AND ALSO BEGIN TO SAG SOUTHWARD WITH TIME. IT SHOULD ALSO LEAVE BEHIND A ROUGHLY EAST WEST OUTFLOW BOUNDARY SOMEWHERE NEAR THE IA/MN BORDER...WHICH WILL LIKELY CONTINUE TO CREEP SOUTHWARD AND PROVIDE A FOCUS MECHANISM FOR CONTINUING THUNDERSTORM DEVELOPMENT ACROSS NORTHERN IOWA LATER TONIGHT AS THE NOCTURNAL LLJ KICKS IN. GIVEN AMPLE INSTABILITY AND MOISTURE...SEVERE WEATHER AND HEAVY RAIN WILL CERTAINLY BE POSSIBLE IN THIS AREA. HAVE ORIENTED AND TRENDED POPS ACCORDINGLY AND WILL ALSO ISSUE A FLASH FLOOD WATCH NORTH OF HIGHWAY 20 WHERE HEAVY RAIN IS MOST LIKELY. AT THIS TIME IT DOES NOT APPEAR THAT THUNDERSTORMS WILL BE ABLE TO GET MUCH FURTHER SOUTH THAN THAT...AND THEY MAY NOT EVEN BE ABLE TO GET INTO IOWA MUCH AT ALL...BUT THERE IS CONSIDERABLE UNCERTAINTY REGARDING THE SOUTHWARD EXTENT AND THIS WILL NEED TO BE CLOSELY MONITORED TONIGHT. .LONG TERM.../SATURDAY THROUGH FRIDAY/... ISSUED AT 407 PM CDT FRI JUN 21 2013 GENERAL LOGISTICS OF THE FORECAST REMAIN UNCHANGED OVER THE PAST FEW DAYS. PRIMARY QUESTION FOR CONVECTION ON SATURDAY IS POTENTIAL FOR OUTFLOW TO DROP SOUTH INTO IOWA AGAIN OVERNIGHT INTO SATURDAY MORNING AND KEEP THE POTENTIAL FOR CONVECTION AS FAR SOUTH AS CENTRAL IOWA. MID LEVEL TEMPERATURES ARE A BIT COOLER ESPECIALLY EARLY SATURDAY WHICH WOULD LEAVE LESS INHIBITION ACROSS THE CENTRAL AND NORTH. PRIMARY FOCUS SHOULD BE OVER THE NORTH EARLY AND AGAIN LATE IN THE DAY AND OVERNIGHT WITH THE SHORT WAVE TRAINING CONTINUING TO PASS THROUGH NORTHWEST IOWA. THE INSTABILITY AXIS SHIFTS FURTHER SOUTHEAST INTO CENTRAL IOWA LATE SUNDAY INTO SUNDAY NIGHT AS A LARGE CHUNK THE PACIFIC NORTHWEST UPPER LOW ROTATES NORTHEAST INTO SOUTHERN CANADA. IN ADDITION TO A SEVERE WEATHER THREAT...THE POTENTIAL FOR HEAVY RAIN INCREASES ESPECIALLY SUNDAY NIGHT AS MOISTURE TRANSPORT INCREASES ALONG WITH DEEP WARM CLOUD DEPTHS WITH PWAT VALUES NEARING 1.75 INCHES. 850-300 MB FLOW WOULD SUGGEST THE POTENTIAL FOR TRAINING STORMS ACROSS THE REGION. THE SEVERE WEATHER THREAT WOULD BE MAINLY HAIL AND DAMAGING WINDS. WARM AND HUMID SATURDAY WITH A FEW LOCATIONS HAVING HEAT INDEX VALUES APPROACHING 100 ASSUMING CONVECTIVE DEBRIS DOES NOT PERSIST. GOOD OVERALL CONFIDENCE GOING INTO NEXT WEEK WITH 500 MB HEIGHTS INCREASING EARLY IN THE PERIOD BEFORE STRONG RIDGING DEVELOPS OVER THE INTER MOUNTAIN WEST MID TO LATE NEXT WEEK. THIS WILL ALLOW AN UPPER LOW TO DROP INTO THE WESTERN GREAT LAKES AND SLIGHT COOLER AND LESS HUMID AIR TO DROP INTO IOWA WITH NORTHWEST FLOW. THUNDERSTORM POTENTIAL WOULD BE WITH SHORT WAVE TIMING EARLY THEN THE BOUNDARY LATER IN THE PERIOD. AS MENTIONED PREVIOUSLY THOUGH...THE PRIMARY FOCUS WITH THE FORECAST IS THROUGH THE WEEKEND. && .AVIATION...22/06Z ISSUED AT 1209 AM CDT SAT JUN 22 2013 MAIN CONCERNS WILL BE CONVECTION OVERNIGHT AND WINDS ON SATURDAY. FOR NOW...HAVE CONTINUED CHANCES FOR THUNDERSTORMS OVER THE NORTH BOTH AROUND 09Z THROUGH 14Z AND AT KMCW TWO PERIODS OF STORMS POSSIBLE FROM 06 TO 08Z AND AGAIN FROM ABOUT 10 TO 14Z. KALO WILL HAVE SIMILAR CONDITIONS IF THE STORMS ORGANIZE AND OUTFLOW TO THE SOUTH AS ANTICIPATED. KFOD IS STILL IN QUESTION AND IF THE CAP HOLDS OVER THE CENTRAL AND SOUTHERN AREAS...KDSM AND KOTM SHOULD REMAIN RELATIVELY QUIET THROUGH THE PERIOD. WINDS ARE THE NEXT CHALLENGE AND LIKE TODAY WILL BE STRONG FROM THE SOUTH ON SATURDAY WITH GUSTS FROM 24 TO 30KTS ACROSS THE REGION. LOW CONFIDENCE BUT THUNDERSTORMS MAY AGAIN DEVELOP LATE DAY NORTH CLOSER TO THE BOUNDARY. WILL ADDRESS THAT IN THE 12Z PACKAGE. /REV && .DMX WATCHES/WARNINGS/ADVISORIES...
