A prolonged and exceptionally wet fall combined with successive flash flood events in eastern Iowa and northwest Illinois to bring widespread minor to moderate river flooding to nearly all rivers in this area. In addition, major flooding occurred on rivers, including the Mississippi, Iowa, Wapsipinicon, English, North Skunk, Maquoketa, and Rock Rivers.

The episode as NWS DVN wrote it up.
A prolonged and exceptionally wet fall combined with successive flash flood events in eastern Iowa and northwest Illinois to bring widespread minor to moderate river flooding to nearly all rivers in this area. In addition, major flooding occurred on rivers, including the Mississippi, Iowa, Wapsipinicon, English, North Skunk, Maquoketa, and Rock Rivers. This major flood event stretched through much of mid October.
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 Oct 8, 11:50 AM CST, 10 minutes earlier.
Area Forecast Discussion
National Weather Service Quad Cities IA IL
1250 PM CDT Mon Oct 8 2018
...18z AVIATION UPDATE...
.SYNOPSIS...
Issued at 301 AM CDT Mon Oct 8 2018
Frontal boundary lifting through the area at this time with
showers and storms along and north of it. Also some isolated areas
of fog noted in parts of east central IA. Temps in low to mid 50s
north of boundary, with mid to upper 60s south.
&&
.SHORT TERM...(Today and Tonight)
ISSUED AT 301 AM CDT Mon Oct 8 2018
Warm front will lift through the area this morning with rain
chances gradually diminishing/ending across the southeast two
thirds of the CWA. Scattered chances will continue across the NW
third or so where we've extended the flash flood watch for through
18Z Tuesday. Despite more scattered nature of storms today, they
will still be good rain-producers. In addition to the heavy rain
threat (and potential flooding), there is also a Marginal risk for
an isolated strong to severe storm generally NW of a line from
Keosauqua to Galena as low level shear remains favorable for storm
rotation. The main threats are damaging winds and a brief weak
tornado. The timing would be mid afternoon into the evening. Showers
and storms will continue into tonight, mainly across areas west
of the Mississippi. Summer-like warmth will be common today, with
highs in the mid 70s to mid 80s. It will be humid as well with dew
points in the 60s. Just another sign indicative of a heavy
rainfall scenario.
.LONG TERM...(Tuesday through Sunday)
ISSUED AT 301 AM CDT Mon Oct 8 2018
The warm and humid conditions will continue Tuesday with shower
and thunderstorm chances increasing again across the entire area
as a surface low moves across Iowa. Highs once again will be in
the 80s, with high humidity levels too.
Late Tuesday afternoon and night a cold front will finally start
to move through the area. This will increase rain chances, with
the bulk of the rainfall; on the order of 0.75 to 1.25 inches;
falling Tuesday evening into mid morning Wed. A flash flood watch
may need to be expanded/extended into midday Wed for parts of the
area. Some of the storms could be strong to severe Tuesday
afternoon and night as shear remains strong, with damaging winds
the main threat. SPC has areas along and west of the Mississippi
in a Slight Risk area. This is expected to come through mainly as
a squall line, but could have embedded stronger individual cells.
In addition to the wind threat, an isolated tornado can not be
ruled out.
Precip gradually exits the area Wednesday as the strong cold
front pushes east across the cwa. This will finally bring an end
to the rainy pattern and usher in much colder and drier air into
the area. Highs Wednesday will be in the upper 50s and 60s.
Much colder conditions are expected Thursday through Sunday with
highs in the upper 40s and 50s.
A quick moving clipper system arrives mid/late Friday morning
which should bring rain to the area. It should exit quickly by
late Friday afternoon. At this time it should be dry across the
area early Friday morning, when temperatures are expected to drop
into the 30s. More rain is expected for Saturday, with dry
conditions Sunday into next Monday.
&&
.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
ISSUED AT 1246 PM CDT Mon Oct 8 2018
MVFR to some lingering IFR CIGs and showers with some embedded
thunder to impact the CID and possibly the DBQ terminals through
this evening, while MVFR to VFR CIGs occur further to the east of
the action zone acrs the rest of the area well into tonight.
South to southeast winds of 8-13 KTS in general, with some late
night decrease possible especially at CID. This may make for
marginal low level wind shear at that site toward dawn if 2000 ft
winds can increase to 40 KTS from the southwest.
&&
.HYDROLOGY...
Issued at 1004 PM CDT Sun Oct 7 2018
Main point...there is high uncertainty regarding the river
forecasts on the Cedar river for Vinton and Cedar Rapids. The
forecast is all based on qpf. If the qpf is considerably less than
forecast, the the river may not reach flood stage at Vinton and
may be much lower that forecast at Cedar Rapids.
New flood warnings were issued for the La Moine and part of the
Skunk rivers.
A new flood watch was issued for a part of the Mississippi river.
All rivers continue to rise due to the continued rainfall across
the area. Major flooding is expected or is occurring on parts of the
Iowa, Mississippi, Rock, and Wapsipinicon rivers. Moderate
flooding is occurring or is expected on the lower Cedar, parts of
the Iowa, Mississippi, and North Skunk rivers.
Another round of rain, possibly heavy, is expected Tuesday into
Wednesday.

Area rivers are experiencing flooding. Please see the latest Flood Statements and Flood Warnings for details. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY Heavy rainfall is possible over portions of eastern Iowa on Tuesday, and over the entire outlook area Tuesday night ahead of a strong cold front. A few severe storms are also possible Tuesday evening and night, and the Storm Prediction Center has placed much of the area in a slight risk for severe weather.
