DoomWhat forecasters said that day
The local office's own words before this river flood advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Chicago, IL wrote its last area forecast discussion before this river flood advisory went out at Oct 28, 6:44 PM CDT, 1 hour 57 minutes earlier.

.SHORT TERM...
315 PM CDT
Through Friday night...
A 992 mb surface low centered over southern Missouri continues
its slow movement towards the east-northeast, with light to
moderate rain rotating around it, especially towards its northeast
where dynamic support is stronger (upper level jet support and
diffluence). Although surface winds are from the east, winds
become more southeasterly with height, and that is helping move
rain over the area. Rain amounts have mainly been light so far,
and upstream too, though a couple reports around one half inch in
eastern Illinois. Showers will continue late this afternoon into
this evening. There may be some diminishing and light fog in the
far south later tonight as the low shifts into the Lower Ohio
River Valley, but otherwise rain showers are likely to prevail.
This looks to be even a steady rain over parts of northeast
Illinois later tonight and continuing into Friday morning, where
lake enhancement will be a factor due to onshore flow and
relatively warm lake temperatures inducing lake-effect
instability. This could result in some widespread slower
conditions during the Friday morning commute due to the widespread
rain.
As the low moves closer, winds will pick up due to the tightening
surface gradient. Gusts up to 35 to 40 mph will be possible
starting mid morning and into Friday evening, especially near the
lake front. This strong northeasterly flow will create high waves
along the Lake Michigan shore of Illinois especially, with regular
wave heights on Friday as high as 10-11 ft tonight. This is less
than the waves with the storm earlier this week, however still may
end up resulting in spotty issues of minor flooding or spray from
the lake.
Rain continues throughout Friday and into Friday night but likely
focuses more in the eastern CWA. With still continued lake
enhancement, it is expected that far northeast Illinois, including
the Chicago metro, will see the most rain with this event. We
have inched up our forecast rainfall amounts with some locations
receiving over 1.25 inches looking more likely. Cannot rule out 2
or even a little over, considering the 12Z HREF probability
matched mean (PMM) guidance indicates that for an event total in
northeast Illinois. This is likely not to be enough for flooding,
but may present some ponding issues during the morning commute.
Cloud cover will keep temperatures fairly steady over the next 36
hours or so, with temperatures remaining in the low to mid 50s,
including lows Friday morning. Winds will become more northerly by
Saturday morning, so although we'll still have widespread cloud
cover, temperatures will be a bit cooler Saturday morning, with
lows in the upper 40s/near 50.

.LONG TERM...
315 PM CDT
Saturday through Wednesday...
The key messages in the extended period include 1. pleasant
weekend weather in store for Halloween and 2. consensus that we
are entering a cooler than normal pattern bringing more widespread
sub-freezing temps to the area and possibly our first snowflakes
of the season.
The closed upper low responsible for our late week rain showers
will be well on its way east of the area by Saturday. North
northeast winds will persist on the back side of the low, however,
which could bring some lingering lake effect showers through the
morning hours across northeast Illinois near the lake then
trending east into northwest Indiana over the afternoon. A cold
front does push through the area sometime Sunday morning which
will bring some breezy northwest winds and limit warming only
into the mid-upper 50s in the afternoon. Dry conditions are still
on tap on Sunday which should make for a pleasant Halloween.
Temperatures do begin to cool down after sunset with mid-upper 40s
in the city and the lower 40s in the suburbs expected in the
evening for Trick-or-Treat time.
Beyond the weekend, cold air from Canada continues to dive
southward across the Upper Midwest. This will bring below normal
temperatures across the area for the remainder of the work week
with high temperatures only in the 40s. In turn, temperatures
overnight will begin to dip into the lower 30s with more
widespread sub-freezing temps becoming increasingly likely,
especially across more rural areas outside of the metro later in
the week. As to be expected when temperatures dip below freezing,
we could very well see our first snowflakes of the season. At
this time there remains some variability and thus uncertainty with
the timing and placement of various mid-level shortwaves rounding
the base of the upper trough, so for now will simply maintain
slight chances for light rain/snow off and on during the Monday
through Thursday period.

.AVIATION...
For the 00Z TAFs...
Aviation Forecast Concerns:
* IFR ceilings through the period, with some potential for LIFR
300-400 foot later tonight/early Friday morning. Visibility high
end IFR to MVFR in showers/drizzle/fog much of the period as
well.
* Northeast winds gradually back north-northeast and increase and
become gusty near 30 kts Friday.
Surface low pressure was located near the confluence of the Ohio
and Mississippi rivers early this evening. This disturbance will
continue to track slowly to the east-northeast across the Ohio
Valley through Friday. Cyclonic (counter-clockwise) flow around
the northern periphery of the low will continue to pull moisture
across the forecast area through the period, resulting in fairly
persistent showers/drizzle (and resulting low clouds/vis) for the
terminals through much of the TAF period. Extensive MVFR ceilings
were already in place across northern IL/IN early this evening,
with pockets of IFR and visibility 3-4SM in spots in rain and
light fog. Expectation is for IFR ceilings to expand early this
evening, and gradually lower overnight. Some guidance continues to
indicate the potential for a period of patchy 300-400' LIFR
ceilings across the Chicago terminals after midnight.
IFR conditions, showers and light fog are expected to persist
through the day and into the evening Friday for the Chicago
terminals, while conditions likely improve a bit farther to the
west at KRFD by later afternoon. Otherwise, east-northeast winds
will back to northeast overnight and to north-northeast Friday as
the low passes to the south of the area. Tightening of the
pressure gradient and cooler air aloft supporting better low level
mixing over Lake Michigan will result in winds increasing near 20
kts with gusts near 30 kts especially later in the
afternoon/evening.

.MARINE...
315 PM CDT
Another strong low pressure system will move eastward across the
middle of the country over the next 36 hours, though this one
further south than the earlier week one. The pressure gradient
and lower atmospheric winds will be less over the area with this.
With instability still over the lake, the potential for some 35 kt
gales on Friday is there, namely into the Illinois nearshore.
Confidence is high that if a gale ends up occurring, it would not
exceed a mid 30 kt gale.
