The episode as NWS DMX wrote it up.
A cold front moved through the state during the afternoon and evening hours of the 17th of July, eventually stalling out and lingering across central and southern Iowa. Resulting issues were primarily heavy rain focused, with amounts generally in the 2 to 4 inch range with a lone report of over 5 inches. A couple flash flood reports occurred as a result of the heavy rainfall. In addition to the heavy rainfall, a couple of severe storms were reported with hail and damaging winds.
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 Des Moines, IA wrote its last area forecast discussion before the first event at Jul 17, 3:15 PM CST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Des Moines IA 415 PM CDT Sun Jul 17 2016 .SHORT TERM.../Tonight/ Issued at 356 PM CDT Sun Jul 17 2016 Very difficult forecast tonight as the convection from earlier today has modified the airmass over Iowa. However with the clearing taking place and the cold front still off to the West we should continue to destabilize through late afternoon into the evening hours. Northern Iowa appears to be considerably more stable than the Southeast half of the state however it appears that further convection will wait for a shortwave over the central plains to move East as the cold front inches across the forecast area. The result will be a redevelopment of storms from early to mid evening into the overnight hours. Radar is showing storms festering over Eastern Nebraska and the HRRR model depicts this remarkably well. I based much of the timing off the HRRR and trying to time the shortwave coming in. The potential for damaging wind and heavy rain will again exist with the storms. .LONG TERM.../Monday through Sunday/ Issued at 356 PM CDT Sun Jul 17 2016 Storms should clear the Southern/Southeast portion of the forecast area by early morning and clouds should clear some but low level moisture will not be scoured completely out by the frontal passage and we should see a fair amount of cloud cover through the day. Monday night and Tuesday we will see a return of strong warm advection and deeper moisture returning along with a decent shortwave pushing across Iowa...especially from 09Z Tuesday through about 18Z Tuesday. This will bring another round of strong to severe storms and heavy rainfall to the area. Lingering storm chances occur into Wednesday as we remain on the East side of the building ridge axis and some weaker shortwaves top this ridge. For later Wednesday through at least Friday, temperatures will be quite hot and with dewpoints in the mid 70s it will be very muggy with oppressive heat in place Thursday. Some relief looks likely over the weekend as a strong shortwave flattens the ridge in place bringing temps back down...along with a chance for storms. && .AVIATION.../For the 18Z TAFS through 18Z Monday afternoon/ Issued at 1250 PM CDT Sun Jul 17 2016 Low confidence forecast today. It is unclear how much the morning storms have modified the airmass for thunderstorm redevelopment and how fast a frontal boundary will move into the state and whether the front will stall or slowly move through TAF locations. Some clearing is expected this afternoon returning to VFR conditions with patchy MVFR conditions North and East. It is looking more plausible that additional storms will wait until an upper level disturbance pushes in later this evening with the DSM and OTM mainly being affected from 03Z through 09z. Gradual clearing expected aft 12z. && .DMX WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...FAB LONG TERM...FAB AVIATION...FAB
