During the overnight hours on July 11th into the morning of July 12th a strong line of thunderstorms moved out of southeast Nebraska and southern Iowa into northern Iowa. The extent of the damage across the area was relegated to mostly trees and some isolated structural damage, namely in Bates County Missouri.

The episode as NWS EAX wrote it up.
During the overnight hours on July 11th into the morning of July 12th a strong line of thunderstorms moved out of southeast Nebraska and southern Iowa into northern Iowa. The extent of the damage across the area was relegated to mostly trees and some isolated structural damage, namely in Bates County Missouri. The heavy rain from this system also brought some minor flash flooding to the area.
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.
NWS Kansas City, MO wrote its last area forecast discussion before the first event at Jul 11, 9:57 PM CST, 4 hours 3 minutes earlier.
Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 1057 PM CDT MON JUL 11 2016 .Update... Issued at 945 PM CDT MON JUL 11 2016 Trend in the HRRR which is finally coming around to reality is to slow down the development of convection and potential MCS into the CWA. Radar and 00z NAM support this as convection has sputtered along the cold front from south central NE into central KS despite the presence of a 40-45kt h8 jet as noted in the latest VWPs. 00z TOP sounding says it all...airmass is capped east of the cold front. Am watching the large outflow boundary now dropping south across east central NE/west central IA as new convection should form north of this boundary. Still anticipate convection to form and increase in coverage over the northern CWA. It'll just take longer to get hear. Good chance the convection will decrease in coverage and intensity south of the I-70 corridor. && .Discussion... Issued at 242 PM CDT MON JUL 11 2016 A warm and moist airmass remains in place across the forecast area this afternoon, with dewpoints well into the 70s. A cold front was moving through central Nebraska into northwest Kansas, and this feature will begin to slow this evening as it approaches southeast Nebraska into central Iowa as the upper support lifts northward and the flow becomes parallel with the boundary. Thunderstorms are expected to develop along this boundary late this afternoon into the evening hours upstream of the forecast area. This activity will consolidate into one or more clusters of linear storm segments this evening into the overnight hours as it approaches/moves into the area. While instability will decrease overnight and with southeast extent, a few strong to severe storms will be possible in northwest Missouri, with the primary threat of straight-line winds. Additionally, the most robust storms will be capable of producing heavy rainfall, so areas with any repeat convection may see a localized flooding threat. Thunderstorms will be weakening as they move across the remainder of the forecast area around/after sunrise Tuesday. There remains some uncertainty to the coverage of precipitation and cloud cover in the wake of the morning convection, and this may alter high temperatures and the intensity of another round of thunderstorms Tuesday afternoon and evening. The current thought is convection will redevelop along/near the stationary surface front in southern Iowa into northwest Missouri Tuesday afternoon. This activity will gradually consolidate and shift south and east through a good portion of the forecast area Tuesday evening into the overnight hours. Again, depending on the available instability, some storms may be strong to severe, especially within the first 3-6 hours of initiation. Models are currently in decent agreement in a break of convection Wednesday morning into the early afternoon, and likewise develop a strongly unstable airmass ahead of the quasi-stationary front. Another round of thunderstorms are expected to develop once again, this time with the boundary drifting slowly southward. With stronger low-level forcing, sufficient deep layer shear, and an unstable atmosphere, severe thunderstorms will be a possibility with storms that develop during the afternoon and evening hours. The exact evolution remains still too uncertain with several details yet to be resolved. Thursday into the weekend features continued chances for periods of thunderstorms. Outside of the severe weather threat, flooding concerns will commence for areas with repeated convection during the multi-day event. The greatest rainfall totals are expected to be located across the northern third of Missouri, generally along and north of Interstate 70. && .Aviation...(For the 06Z TAFS through 06Z Tuesday Night) Issued at 1058 PM CDT MON JUL 11 2016 Thunderstorm complex over east central NE/west central IA is expected to sag south and into northern MO overnight. MVFR ceilings expected with the stronger cells. Activity will likely continue south towards the KC terminals during the pre-dawn hours and decrease in coverage and intensity. Some concern that new convection forming along the KS portion of the cold front could track east and into east central KS/west central MO towards sunrise. Models having a difficult and slow time adapting to current convective trends. Difficult to gauge where any of the outflow boundaries will end up as they will likely dictate where new convection forms later Tuesday afternoon and evening so best to broadbrush with VCTS and VFR ceilings/visibilities. && .EAX Watches/Warnings/Advisories...
