What happened
The episode as NWS DMX wrote it up.
The weather pattern was similar to what it was the previous night into the morning of the 21st, only things were shifted south of Iowa. A large complex of storms formed over northeast Kansas into northern Missouri during the late afternoon and evening hours. A few of the storms crossed the Iowa border. One of them was severe and produced penny size hail in Wayne County.

Area forecast discussion, Jul 21, 5:57 PM CST, 2 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 657 PM CDT MON JUL 21 2008 .SHORT TERM.../REST OF THIS AFTERNOON AND TONIGHT/ PRIMARY SFC BOUNDARY DIPPED SOUTH INTO NORTHERN MISSOURI AFTER BEING INFLUENCED FROM SOUTHERN MOVING OUTFLOW BOUNDARY FROM THE MORNING CONVECTION. CURRENTLY SOUTHERN IOWA REMAINS CAPPED DUE TO WARM AIR AT AROUND 800 MB. STRONG SHORT WAVE NOW DROPPING SOUTH THROUGH THE DAKOTAS WILL GRADUALLY BRING COOLER MID LEVEL TEMPERATURES AND EFFECTIVELY ERODING THE CAP. EXPECT STORMS TO FIRE OVER SOUTHEAST NEBRASKA TO SOUTHWEST IOWA LATE THIS AFTERNOON AND PROCEED TO THE EAST SOUTHEAST OVER SOUTHERN IOWA. ENVIRONMENT STILL PRIMED FOR ANOTHER SEVERE EVENT LIKELY. LIKELY EVOLUTION SIMILAR TO LAST EVENING WITH INITIAL SUPERCELLS...MOST LIKELY HP...EVOLVING INTO AN ORGANIZED BOW ECHO AND TRACKING JUST NORTH OF THE SFC BOUNDARY THIS EVENING. HEAVY RAINFALL POTENTIAL LACKING WITH PROGRESSIVE NATURE OF STORMS THOUGH INTENSE RAINFALL RATE CAN BE EXPECTED WITH ANY STORMS THAT DEVELOP. SYSTEM WILL BEGIN TO MOVE OUT OF SOUTH CENTRAL IOWA TOWARDS MIDNIGHT. .LONG TERM.../TUESDAY THROUGH MONDAY/ TUESDAY AND WEDNESDAY WILL BE MOSTLY DRY AS SURFACE HIGH PRESSURE BUILDS DOWN THE UPPER MIDWEST AND GREAT LAKES REGION. SLIGHT CHANCES FOR RAIN WILL REMAIN IN THE FAR SOUTH TUESDAY MORNING...THE REMNANTS OF OVERNIGHT CONVECTION MOVING OUT...AND POSSIBLY THE NORTHEASTERNMOST COUNTIES AS A SUBTLE SHORTWAVE MOVES AROUND A LARGE AND DEEP GYRE CENTERED NORTHEAST OF THE GREAT LAKES. BOTH OF THESE FEATURES WILL BE GONE BY TUESDAY NIGHT...LEAVING US DRY FOR WEDNESDAY. BOTH DAYS WILL ALSO BE MILD AS WELL WITH COOLER AND DRIER AIR ADVECTING AROUND THE SURFACE HIGH FROM THE UPPER GREAT LAKES. THIS BRIEF RESPITE WILL BE INTERRUPTED WEDNESDAY NIGHT...AS A MID LEVEL RIDGE PASSING OVERHEAD WILL AMPLIFY NORTH NORTHWESTERLY STEERING FLOW...AND A LONG SURFACE TROUGH STRETCHING FROM CANADA DOWN THE WESTERN PLAINS WILL ADVANCE EASTWARD THROUGH THE AREA. ECMWF HAS BEEN INCREDIBLY CONSISTENT WITH THIS FEATURE FOR SEVERAL DAYS...ALTHOUGH ITS TIMING HAS BEEN PUSHED BACK JUST SLIGHTLY AND NOW APPEARS MOST LIKELY AFTER MIDNIGHT WEDNESDAY NIGHT. GFS AND NAM APPEAR TO BE INDICATING AN MCS MOVING QUICKLY SOUTH SOUTHEAST IN THE FLOW DURING THE NIGHT...WITH THE NAM TAKING IT JUST SOUTHWEST OF US NEAR OMAHA AND KANSAS CITY AND THE GFS TAKING IT DIRECTLY OVERHEAD. DYNAMICS AND SHEAR SHOULD BE SUPPORTIVE OF THIS...BUT IT REMAINS TO BE SEEN WHETHER GOOD THETA-E ADVECTION ASSOCIATED WITH THE MID LEVEL RIDGE WILL BE ABLE TO OVERCOME AN INITIAL LACK OF LOW LEVEL INSTABILITY IN TIME. HAVE INCREASED RAIN CHANCES TO UPPER LIMITS OF CHANCE POPS...HOWEVER SEVERE POTENTIAL IS CONDITIONAL AND THERE IS A POSSIBILITY THAT MUCH OF THE RAIN COULD MISS US JUST TO THE SOUTHWEST SO HAVE NOT INCLUDED ANY LIKELIES AT THIS TIME. ONCE THIS SYSTEM CLEARS OUT BY LATE THURSDAY WE WILL ONCE AGAIN BE AT THE MERCY OF WEST NORTHWESTERLY FLOW. THERE IS ANOTHER POSSIBILITY OF THUNDERSTORMS LATE FRIDAY AS A SHORTWAVE DIGS THROUGH THE GREAT LAKES AND WISCONSIN...AND GFS INDICATES A GOOD DEAL OF INSTABILITY AFTER A DAY AND A HALF OF ROUGHLY SOUTHERLY MODIFYING SURFACE FLOW. HOWEVER...ANY SUCH CONVECTION WILL BE HEAVILY DEPENDENT ON A SURFACE BOUNDARY /AKA BACK DOOR COLD FRONT/ WHICH THE EXTENDED MODELS ARE HAVING TROUBLE RESOLVING. HAVE INCLUDED ONLY SLIGHT POPS FOR FRIDAY AND FRIDAY NIGHT AT THIS TIME. && .AVIATION...22/00Z SCATTERED THUNDERSTORMS ALONG I80 WILL CONTINUE MOVING SLOWLY SOUTHWARD EXITING DSM BY 01Z AND OTM BY 03Z. FOD/MCW/ALO WILL NOT BE AFFECTED. AFTER 03Z...VFR CONDITIONS ANTICIPATED EXCEPT FOR MVFR FOG POTENTIAL AROUND MCW TOWARD DAYBREAK. && .DMX WATCHES/WARNINGS/ADVISORIES...NONE. && LEE/DONAVON/SMALL
