Major Mississippi River flooding continued into June as rivers remained high during the month of May. Heavy rain in the later part of the month resulted in the river rising back above major flood stage in late May and flooding continued into the first 6 days of June.

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 Quad Cities, IA wrote its last area forecast discussion before the first event at May 31, 11:46 PM CST, 14 minutes earlier.
Area Forecast Discussion National Weather Service Quad Cities IA IL 1246 AM CDT Sat Jun 1 2019 ...AVIATION UPDATE... .SYNOPSIS... Issued at 301 PM CDT Fri May 31 2019 A cold front stretched from a surface low near Duluth westward across the SD/ND border. A warm front extended eastward from allow along the Upper Peninsula and Wisconsin border. Ahead of these fronts, temperatures were in the upper 70s to lower 80s across eastern Iowa, northwest Illinois, and far northeast Missouri. Dewpoints were in the lower 60d across the area. Dense wildfire smoke aloft was working to keep temperatures lower across the area as well as inhibiting diurnal cumulus development. && .SHORT TERM...(This Evening through Saturday) ISSUED AT 301 PM CDT Fri May 31 2019 The main forecast concerns will be chances of storms tonight and Saturday. Models are in good overall agreement through the period. Wildfire smoke has limited temperatures this afternoon with forecast temperatures running a degree or two lower than originally thought. This will prevent diurnally driven cumulus development across central Iowa despite higher CAPE values and weak convergence forecast across the area. CAMs had higher temperatures and develop convection that was forecast to drift into the area this evening. I have removed those chances for this evening so a dry evening is expected across the area. Focus then turns to the storm system that will move across the area Saturday. A shortwave moving through the northwest flow aloft will drive a cool front across the area on Saturday morning into the afternoon. Models do depict the better moisture and lift to the east of the area Saturday. Ahead of the front, temperatures will warm into the upper 70s to lower 80s with dewpoints in the lower 60s north of I-80 to the mid 60s south. This will produce CAPE values of 1000 to 2000 J/KG. Deep layer shear will also increase with 30 to 40 knots of shear. Severe thunderstorms will be possible during the afternoon and early evening ahead of the front with decent convergence ahead of the front and weaker lift. SPC has the area in a marginal risk of severe storms north of a Fairfield to Freeport line and a slight risk to the southeast of this line. The main concerns will be large hail and damaging winds. Rainfall amounts will be lighter than they have been of late which which means there are no expected impacts to the river forecasts. .LONG TERM...(Saturday Night through Friday) ISSUED AT 301 PM CDT Fri May 31 2019 Once again with flood operations dominating our area, we are leaving the forecast for the extended mainly with the blended data, with surrounding offices. This is exactly how the process is intended to run, as this blended data is very hard to "beat" in the extended, especially in the warm season without significant air mass changes. In any case, the period from Sunday through Monday is dry and pleasant followed Saturday afternoon's fropa. The line of storms should exit the area quickly, and pops are only retained for a few hours early Saturday evening, that these may not be needed given the quick progression of the front. Highs Sunday and Monday should top out in the lower to mid 70s, with low humidity. South winds, humidity and warmer temperatures will be back for Tuesday through Friday, with some threat for showers and storms. For now, nothing appears too organized, or capable of repeat rains, expect for possibly Tuesday night into Wednesday. This period, the GFS is very aggressive, while the ECMWF and GEM are far less favorable for heavy rains. I attribute this difference to the GFS overdoing surface dewpoints and moisture transpiration, which despite out recent wet weather, crops are not going to produce significantly given the unplanted or young crops dominating so much of the upper Midwest. && .AVIATION...(For the 06Z TAFS through 06Z Saturday Night) ISSUED AT 1231 AM CDT Sat Jun 1 2019 Scattered thunderstorms are expected to form along a cold front across E Iowa and NW Illinois during the mid to late afternoon. Based on timing of the front, best chances for storms is at KMLI/KBRL. However, coverage may remain low, so for now only mentioned -TSRA in TAFs. May have to include TEMPOs in later updates for brief IFR/LIFR in vicinity of stronger storms. && .HYDROLOGY... Issued at 149 PM CDT Fri May 31 2019 On the Missouri side of the river, adjacent to Quincy Illinois, a levee breech on the Mississippi River has allowed a significant amount of water to empty from the main river channel up through Keokuk IA. That both lowered stages at Keokuk through Gregory Landing but also has likely resulted in the previous day's readings as the actual crest level for those sites. Otherwise, for both the significant flooding of lower tributary sections and the Mississippi, the crests should be occurring from today through Saturday, and on Sunday in a few cases. Some spotty significant rainfall is possible tonight through Saturday, but for rivers, this is far from a confident placement of QPF to warrant a forecast of much run off, thus the most likely scenario is that the next 48 hours will see our highest levels this round. The areal flooding has been slow to improve, but calling around to all the counties in our southern warning, has shown preference for allowing the areal flood warning to expire, but this is not 100%. For Henry IA, Clark MO, Hancock and Henderson IL, the warning has been asked to continue. The Green River breach near Deer Grove continues to flood mainly Ag land in that advisory area on the north band of the Green River. Local EM says the situation is stabilized, but not yet backfilling into the Green, despite seeing a falling Green River stage. This process is expected to begin soon. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE.

Please see the latest Flood Statements and Flood Warnings for details. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY Thunderstorms are likely along a cold front on Saturday, especially during the afternoon. There is a slight risk for severe thunderstorms south of a Milledgeville, Illinois to Davenport, Iowa to Keosauqua, Iowa line. There is a marginal risk over the remainder of the outlook area. The main risks will be damaging winds, large hail and frequent lightning. Thunderstorms are possible Tuesday through Thursday.
