What forecasters said that day

The local office's own words before this river flood warning went out, 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 this river flood warning went out at Sep 3, 6:48 PM CDT, 2 hours 40 minutes earlier.

Area forecast discussion, Sep 3, 6:48 PM CDT, 2 hours 40 minutes before
Area Forecast Discussion
National Weather Service Quad Cities IA IL
648 PM CDT Mon Sep 3 2018

...AVIATION UPDATE...

.SYNOPSIS...
Issued at 310 PM CDT Mon Sep 3 2018

Frontal boundary extends roughly along I-80 in the dvn cwa and
then extends to northeast IL. Shear was stronger along this
boundary so will need to keep an eye on any storm forming along
this front. SPC has a marginal risk for much of the cwa through
this evening.

Mid afternoon temperatures were in the 70s to around 80 north of
the front to well in the 80s to around 90 to the south. Dewpoints
were in the lower to mid 70s with PWAT's around 2 inches.

&&

.SHORT TERM...(This Evening through Tuesday)
ISSUED AT 310 PM CDT Mon Sep 3 2018

Tonight: At least scattered storms can be expected through the
evening with a continued moisture transport of PWAT's of 2 inches,
and in the SBCAPE gradient. Therefore, the flash flood watch
remains in effect through the evening hours, due to the very
saturated soils. Later tonight heights rise a bit allowing for
the frontal boundary to shift northward. Another warm and muggy
night is in store with lows around 70.

Tuesday: Much of the day appears to be dry as the better forcing
extends from western IA into MN/WI, closer to the retreating
boundary. Another very warm and humid day with dewpoints in the
lower to mid 70s and highs in the 80s. Heat index values will push
into the 90s. Late in the afternoon storms may return in our nw
cwa ahead of an approaching cold front.

.LONG TERM...(Tuesday Night through Monday)
ISSUED AT 310 PM CDT Mon Sep 3 2018

More heavy rainfall/flash flooding expected into the weekend.

Tuesday night and Wednesday: Persistent upper level high will be
centered in the mid-Atlantic states pumping high PWAT air
northward into the Midwest. Upper level trough moving across the
upper Midwest will push a cold front into the dvn cwa and then
stalling. Additional rounds of thunderstorms producing heavy
rainfall can be expected. Meanwhile, potential CAT 1 hurricane
"Gordon" is forecast to make landfall in the central Gulf Coast
region.

Wednesday night through Friday: Pattern remains persistent with a
zonal flow across the area, providing several more rounds of
thunderstorms, with additional heavy rainfall. This appears to a
"predecessor rain event" (PRE) situation ahead of the remnants of
"Gordon", which will be pushing into western MO by late in the
week. Highs will be in the 70s due to the very moist conditions
and expected extensive cloud cover.

Friday night through Saturday night: GFS/ECMWF/Canadian all
indicate the potential for a very heavy rainfall event as "Gordon"
tracks across northern MO and into central IL. With the stationary
frontal boundary draped across the DVN cwa this will set the stage
for a possible serious rain/flash flood event, considering the
very saturated antecedent conditions and already flooded rivers.
Of course, this assumes the track of the tropical system is
consistent over the course of this week.

Sunday and Monday: Mainly dry with highs in the 70s.

.HYDROLOGY...
Issued at 146 PM CDT Mon Sep 3 2018

Since 6 AM today, additional heavy rain has fallen over the
areas generally north of Highway 30 in Iowa and Illinois this
morning. The afternoon activity thus far is either near and west
of Waterloo, and over our Illinois counties. Storms are small in
size, quick moving around 30 to 35 mph, and are producing
torrential rainfall rates. This continues to offer a flash flood
potential.

The rain which fell in narrow swaths overnight, fell in wide
swaths this morning, and narrow afternoon swaths is enough to have
more or less increased the widespread nature of the river
flooding. Minor to moderate flooding is now expected on most
tributaries in Iowa and on the Rock and Pecatonica in Illinois.

On the lower stretches of the Iowa, Skunk, Wapsi, and Rock,
significant moderate flooding is forecast, and in some cases,
levels just under major. These are in particular need of close
monitoring, as they could possibly exceed major in the week ahead,
mainly if we get heavy rains just ahead of the crests.

The Mississippi River is now expected to reach moderate flood
levels at New Boston, Keithsburg, Gladstone LD/18, and Burlington.
Gregory Landing has minor flooding expected.

The forecast remains wet for well into the extended, even after a
bit of a break in the next 24 hours. Thus, there is water yet to
fall that is not accounted for in these forecasts. Therefore,
change in crest and timing are likely in the week ahead.

Missouri.

.DAY ONE...THIS AFTERNOON AND TONIGHT

A flash flood watch is in effect through this evening for much of
the outlook area, and there is also a low risk for severe storms.
The main threats will be possible flash flooding and localized
damaging wind.

Area rivers are experiencing flooding. Please see the
latest Flood Statements and Flood Warnings for details.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

Tuesday night through Saturday night: More rounds of thunderstorms
can be expected during this time frame. Heavy rainfall and
possible flash flooding will continue to be a concern. The
remnants of tropical system "Gordon" will then track into the
Midwest from the Gulf Coast and cause very heavy rainfall and
flash flooding, along with additional river flooding.

.SPOTTER INFORMATION STATEMENT...

There is a low chance that spotter activation will be needed
through this evening. However, any reports of new flooding or
flash flooding would be appreciated.
