After a moderate to heavy rainfall event providing 2 to 3 inches just prior to this, the pump was primed so to speak for flooding potential. A generally stationary front resided south of the area into Missouri, but upper level and mid level flow strongly suggested storms would track north of the surface boundary and across portions of southern and central Iowa. The initial wave of rain was initiated by a mid-upper level short wave riding the parent flow, triggering storms in the Oklahoma-Kansas region by late morning and traveled northeast throughout the day, eventually reaching Iowa by the late afternoon and evening. The initial round exited and subsided by midnight, only to see a second round initiated by the low level jet back in northeast and central Kansas. That second round made its way into southern Iowa by around 6 am and continued throughout the morning. When all said and done, heavy rainfall in excess of 5 inches was reported in a few locations, as well as multiple reports of flash flooding.
