The episode as NWS DVN wrote it up.
A line of showers and thunderstorms dove southeastward across the area during the early morning hours of September 5 providing the area with high winds and brief heavy rains. Some of the storms were severe, producing damaging wind gusts over 60 mph. Some of the hardest hit areas were Iowa City, Muscatine, Burlington, and Montrose, where tree limbs and utility poles were downed. Rainfall totals of a half inch to an inch and a quarter were common roughly northwest of a line from Fort Madison, IA to Princeton, IL with some locally higher amounts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

HAVE COORDINATED WITH SPC AND LOT ON NEW SEVERE TSTM WATCH UNTIL 07Z FOR MUCH OF THE AREA ALONG AND ESPECIALLY NORTH OF HWY 30. THE AFFORMENTIONED OUTFLOW IS PUSHING INTO NORTHERN JACKSON AND SOUTHERN JO DAVIESS ATTIM AND HAS PRODUCED GUSTS TO AROUND 45 MPH NEAR DUBUQUE. OVERNIGHT LOOKS LIKE GREATEST PCPN CHCS WILL BE ACROSS THE NORTH 1/3-1/2 WITH SOME INTERACTION BETWEEN REMNANT BOUNDARY AND ARCING CONVECTION MOVING INTO NORTHERN IL... AND CLUSTERS OF STORMS MOVING THROUGH EASTERN SD. PREV DISCUSSION... /ISSUED 258 PM CDT TUE SEP 4 2012/ SYNOPSIS... INTERESTING SET UP OVER THE REGION THIS AFTERNOON. WITH SUNNY/MOSTLY SUNNY SKIES...TEMPERATURES HAVE RISEN INTO THE UPPER 80S TO LOW 90S EVERYWHERE...WITH DEWPOINTS IN THE UPPER 60S TO LOW 70S. THIS HAS CAUSED SURFACE BASED CAPE VALUES TO RISE INTO THE 2500 TO 3500 G/KG RANGE...WITH 0-6KM SHEAR IN THE 30-40KT RANGE. THIS IS SUPPORTIVE OF SOME VERY INTERESTING CONVECTION...IF WE COULD ONLY GET IT GOING. THERE IS A WEAK BOUNDARY EXTENDING SOUTH FROM A SURFACE LOW OVER NORTHERN MINNESOTA TO CENTRAL IOWA...BUT IS LITTLE MORE THAN A WIND SHIFT LINE WITH LITTLE/NO CONVERGENCE ALONG IT IN IOWA. ALSO...PRESSURE FALLS ARE MUCH BETTER UP INTO WISCONSIN AND MINNESOTA THAN IOWA. SO...WHILE WE WILL BE WATCHING CAREFULLY FOR ANY SIGNS OF CONVECTIVE DEVELOPMENT THIS AFTERNOON AND EVENING...IT IS LOOKING LESS LIKELY. THERE WAS AN INTERESTING LITTLE CELL IN NORTHWEST IOWA THAT WAS SITTING IN A MOISTURE CONVERGENCE AREA...BUT IT NEVER GOT BEYOND THAT...AND HAS SINCE FALLEN APART. ALSO OF NOTE TODAY THERE IS ANOTHER SURFACE LOW NEAR VALENTINE NEBRASKA...WITH SOME NICE PRESSURE FALLS TO ITS NORTHEAST...AND THE WESTERN EDGE OF THE POOL OF HIGH DEWPOINTS JUST TO ITS EAST. ..LE.. SHORT TERM...TONIGHT AND WEDNESDAY... AM MAINTAINING SOME SLIGHT AND LOW END CHANCE POPS FOR THIS AFTERNOON AND EVENING IN CASE CONVECTION DOES GET GOING OVER NORTHERN IOWA AND SOUTHERN MINNESOTA THIS EVENING THAT MAY GET INTO THE AREA...BUT CONFIDENCE IS NOT ESPECIALLY HIGH. LATER TONIGHT...THE SURFACE LOW OUT OVER NEBRASKA THIS AFTERNOON WILL MOVE EAST AND ALONG WITH SOME NICE MID LEVEL CONVERGENCE SHOULD FIRE AN MCS OVER WESTERN OR NORTHWESTERN IOWA...WHICH SHOULD THEN MOVE IN AND EAST-SOUTHEAST TRACK...AND MOVE ACROSS ABOUT THE NORTHERN HALF OF IOWA LATE TONIGHT AND WEDNESDAY MORNING. SOME MODELS ARE PUTTING THE INITIATION AREA FARTHER NORTH...AND IN GENERAL IMPLIES THAT THE BETTER POSSIBILITIES FOR CONVECTION ARE ACROSS THE NORTHERN CWA OR TO AREAS FARTHER NORTH. THUS...HAVE SHIFTED POPS NORTH AND LATER IN TIME. IT SHOULD JUST GET INTO THE NORTHWESTERN CORNER BY 12Z...AND MOVING ACROSS THE REST OF THE CWA DURING THE MORNING AND EARLY AFTERNOON. DO HAVE CONCERNS THAT THE WHOLE THING COULD MISS US TO THE NORTH. HOWEVER...WE HAVE A VERY NICE POOL OF UNTAPPED CAPE FOR STORMS TO EAT INTO AS LONG AS WE ARE NOT CAPPED...AND CAN SEE CONVECTION DRIVING FARTHER SOUTH THAN THE MODELS INDICATE. MIN TEMPS TONIGHT TO BE VERY SIMILAR TO LAST NIGHT...THOUGH CLOUDS WILL KEEP THE NORTHERN COUNTIES WARMER THAN THEY WERE LAST NIGHT. WEDNESDAY WILL BE COOLER THAN TODAY WITH THE CONVECTION AND CLOUDS MOVING ACROSS THE AREA DURING THE DAY. HIGHS SHOULD ONLY BE IN THE LOW 80S NORTH...TO AROUND 90 AGAIN ACROSS THE SOUTH WHERE CLOUDS AND PRECIP SHOULD HOLD OFF THE LONGEST. ..LE.. LONG TERM...WEDNESDAY NIGHT THROUGH NEXT TUESDAY... FORECAST FOCUS ON FALL TEMPERATURES FOR MUCH OF THIS PERIOD. RAIN LIKELY THURSDAY NIGHT AND FRIDAY OTHERWISE MAINLY DRY. WEDNESDAY NIGHT AND THURSDAY...COLD FRONT WILL HAVE MOVED THROUGH BY WEDNESDAY EVENING SO WILL USHER COOLER AND LESS HUMID AIR INTO THE CWA. LOWS WILL DROP INTO THE 50S TO AROUND 60 WITH HIGHS AROUND 80. THURSDAY NIGHT THROUGH FRIDAY NIGHT...OPERATIONAL MODELS SIMILAR IN DEPICTING A STRONGLY DIGGING TROUGH INTO THE MIDWEST. AT THIS POINT RAIN APPEARS LIKELY ESPECIALLY LATE THURSDAY NIGHT AND FRIDAY... ENDING IN OUR SE CWA FRIDAY EVENING. POTENTIAL FOR OVER AN INCH OF RAIN IN THE SOUTHERN CWA...LESSER AMOUNTS TO THE NORTH. FOR NOW WILL HAVE 40 TO 60 PERCENT POPS BUT THESE MAY NEED TO BE RAISED FURTHER WHEN CONFIDENCE IS HIGHER. MAXIMUM TEMPERATURES ON FRIDAY MAY NEED TO BE LOWERED IF LOW CLOUDS AND RAIN ARE MORE WIDESPREAD THAN INDICATED. SATURDAY THROUGH TUESDAY...DRY NORTHWEST FLOW WITH VERY PLEASANT FALL TEMPERATURES. EXPECTING SUNNY DAYS AND CLEAR NIGHTS WITH HIGHS IN THE 70S AND LOWS MAINLY IN THE UPPER 40S TO MID 50S. HAASE && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE. MO...NONE. &&
