The episode as NWS DMX wrote it up.
An area of thunderstorms moved through the area during the previous night. As the storms moved east an area of high winds developed on the back side of the complex. High winds of 80 to 90 MPH caused damage in Calhoun and Webster Counties. Winds were recorded at 92 MPH at a Schoolnet sight in Farnhamville. High tension power lines were blown down southwest of Fort Dodge. A heat burst took place with the temperature at Farnhamville rising from 65 to 90 in a few minutes, at the Fort Dodge rise from 66 to 81 in a few minutes.

NWS Des Moines, IA wrote its last area forecast discussion before the first event at Jun 23, 5:14 AM CST, 4 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 614 AM CDT SUN JUN 23 2013 .SHORT TERM.../TODAY /... ISSUED AT 259 AM CDT SUN JUN 23 2013 .SHORT TERM /TODAY/... CONCERNS FOR STRONG TO SEVERE THUNDERSTORMS AND HEAVY RAIN ARE THE FOCUS FOR THIS FORECAST PERIOD. THE MODELS CONTINUE TO ADVERTISE SOME OF THE WESTERN CONVECTION TO REACH THE AREA THIS MORNING AND THEN DIMINISH AS IT TRACKS TO THE EAST THROUGH MID MORNING. A WAVE ALONG THE BOUNDARY OVER NORTHWEST IOWA WILL TRACK EAST THIS MORNING WITH THE SOUTHERN WAVE BEGINS TO PUSH NORTHEAST THIS AFTERNOON AND TONIGHT. THIS WILL ENHANCE MOISTURE TRANSPORT NORTHEAST THROUGH THE AFTERNOON AND EVENING. TEMPERATURES THIS MORNING ARE ABOUT 5 TO 7 DEGREES WARMER THAN EXPECTED...SO HAVE RAISED THE HIGHS OVER THE SOUTH TO NEAR TO ABOVE 90 AGAIN TODAY. WITH SUFFICIENT INSTABILITY STORMS WILL BEGIN TO REFIRE NORTH NEAR THE NOON HOUR OR EARLY AFTERNOON AND BEGIN TO BUILD SOUTH. THE MODELS SUGGEST WE WILL SEE SOME BACK BUILDING ALONG THE BOUNDARY TODAY AND THIS EVENING WHICH WILL INCREASE THE POTENTIAL FOR HEAVY RAINFALL. THERE IS SOME UNCERTAINTY AS TO WHERE THE GREATEST POTENTIAL FOR FLASH FLOODING IS ...BUT THE NORTH TWO THIRDS LOOK TO BE THE MOST AT RISK FOR NOW...THE SOUTHERN AREAS MAY NEED TO BE ADDED YET TODAY...BUT THEY CAN TAKE A BIT MORE WATER THAN THE REST OF THE AREA. RAINFALL TOTALS OF 2 TO 4 INCHES OR MORE MAY BE POSSIBLE GIVEN POTENTIAL FOR BACK BUILDING ALONG THE FRONT...WARM CLOUD DEPTHS ABOVE 10KFT...AND PWATS OF 1.5 TO 2 INCHES OVER THE AREA. THE LATEST EURO MODEL SUGGESTS THAT THE BULK OF THE ACTIVITY WILL TAKE PLACE DURING THE EVENING AND OVERNIGHT HOURS WHILE THE MESO MODELS ARE HINTING AT AN EARLIER START THIS AFTERNOON. WILL LEAN TOWARD EARLIER START FOR NOW...GIVEN THE INSTABILITY EXPECTED BY THIS AFTERNOON. WINDS WILL BE GUSTY TODAY PRIOR TO THE ONSET OF STORMS. STORMS COULD BRING HIGH WIND AND SOME HAIL...ALONG WITH RAINFALL THREAT TODAY AND THIS EVENING. .LONG TERM.../TONIGHT THROUGH FRIDAY/... ISSUED AT 259 AM CDT SUN JUN 23 2013 FORECAST CONCERNS REVOLVE AROUND THUNDERSTORMS THROUGH TUESDAY. UPPER LEVEL LOW ACROSS SOUTHERN CANADA WILL BE RESPONSIBLE FOR SENDING NUMEROUS SHORTWAVES ACROSS THE UPPER RIDGE WHICH WILL FLATTEN IT. THUNDERSTORMS ARE EXPECTED TO BE ONGOING FROM THIS AFTERNOON ACROSS THE FORECAST AREA THEN BECOME RENEWED AS A LOW LEVEL JET DEVELOPS WITH STRONG MOISTURE TRANSPORT INTO AN AREA OF WARM ADVECTION NEAR A SLOW MOVING SURFACE BOUNDARY. SOME STRONG STORMS ARE POSSIBLE THIS EVENING THEN TRANSITION INTO A HEAVY RAIN THREAT. THE FRONTAL BOUNDARY FINALLY PUSHES EAST THROUGH MOST OF THE FORECAST AREA BY MONDAY EVENING BUT YET ANOTHER SHORTWAVE MOVES ACROSS THE NORTHWEST LIKELY TO DEVELOP ADDITIONAL THUNDERSTORMS. THE SEVERE THREAT FOR MONDAY NIGHT IS A LITTLE LESS CLEAR BUT SOME HEAVY RAINFALL IS POSSIBLE. ANOTHER SHORTWAVE MOVES ACROSS THE NORTHERN PLAINS AND DIVES SOUTHEAST ACROSS NORTHEAST IOWA. ANOTHER FRONTAL BOUNDARY WILL ESTABLISH ITSELF ACROSS THE AREA TUESDAY FOR A CHANCE OF STORMS ONCE AGAIN. FOR NOW I AM CARRYING CHANCE POPS ACROSS THE NORTH MONDAY NIGHT AND NORTHEAST TUESDAY BUT THE FRONTAL BOUNDARY WILL BE KEY TO THE AREAL EXTENT OF THE STORMS. THE LOCATION OF WHICH WILL HOPEFULLY BECOME MORE CLEAR WITH TIME. FOR THE REMAINDER OF THE EXTENDED A STRONG UPPER LEVEL RIDGE BUILDS ACROSS THE ROCKIES PUTTING IOWA IN NORTHWEST FLOW ALOFT. THIS WILL BRING SOME RELIEF FROM THE HEAT AND HUMIDITY HOWEVER...TIMING OF ANY SHORTWAVES DROPPING DOWN ACROSS IOWA IN THE NORTHWEST FLOW IS NEAR IMPOSSIBLE. FOR THIS REASON I DO NOT HAVE POPS IN THE EXTENDED BUT THIS IS DUE TO A LACK OF CONFIDENCE IN TIMING AND LOCATION AND NOT THINKING THAT SHORTWAVE WONT HAPPEN ACROSS THE AREA DURING THIS TIME. && .AVIATION...23/12Z ISSUED AT 614 AM CDT SUN JUN 23 2013 THERE WILL BE OCCASIONAL THUNDERSTORMS THROUGHOUT THE FORECAST PERIOD AND WITH THEM...MVFR CIGS AND/OR VSBYS WITH HEAVY RAIN. STRONG WIND AND POSSIBLY HAIL MAY ACCOMPANY STORMS AS WELL. SFC FLOW GENERALLY SE AT 15G25KTS BUT STRONGER IN STORMS. && .DMX WATCHES/WARNINGS/ADVISORIES...
