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 St. Louis, MO wrote its last area forecast discussion before this river flood warning went out at Jan 11, 5:40 PM CST, 3 hours 39 minutes earlier.

Area forecast discussion, Jan 11, 5:40 PM CST, 3 hours 39 minutes before
Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
540 PM CST Sat Jan 11 2020

.SHORT TERM...  (Through Late Sunday Night)
Issued at 320 PM CST Sat Jan 11 2020

Deformation type precipitation moving through our forecast area
this afternoon with mainly snow and sleet north and west of STL and
patchy light rain and drizzle south and east of STL.  As the
temperatures continue to fall and the cold air deepens the
precipitation will change to all snow across the entire forecast
area by late afternoon and early this evening.  Looking at the CAMS
the snow should shift east of the forecast area by 03Z this evening
and the Winter Weather Headlines should be able to be cancelled
early. Additional snow accumulations of 1 to 2 inches can be
expected across parts of our area, particularly on elevated
surfaces and grassy areas. Did expand the Winter Weather Advisory
east to include the St Louis metro area due to the combination of
snow and sleet which may impact travel. Much colder low temperatures
are forecast tonight which will be close to seasonal normals.
With surface winds diminishing this evening there may be some
patchy fog developing late tonight as the ground is quite wet,
although the surface dew point will be dropping. A fast moving
negatively tilted upper level trough may bring very light snow or
flurries to northeast MO and west central IL Sunday night.

GKS

.LONG TERM...  (Monday through Next Saturday)
Issued at 320 PM CST Sat Jan 11 2020

Will see a warming trend Monday and Tuesday with light rain
possible Monday night. A better chance of precipitation will
occur Wednesday and Wednesday night as a cold front drops
southeastward through our area, followed by colder temperatures
Wednesday night and Thursday. The operational GFS model has the
most significant precipitation threat for Thursday night through
Friday night as a low pressure system moves eastward through MO
and IL. It may be cold enough for a wintry mix Thursday night,
but by Friday afternoon the precipitation type should be liquid
rain.

.AVIATION...  (For the 00z TAFs through 00z Sunday Evening)
Issued at 527 PM CST Sat Jan 11 2020

Area of snow and IFR cigs continues to pull NE through the area.
Conditions are already improving at KCOU/KUIN and are expected to
continue to do so over the next couple of hours. After the snow
ends, expect MVFR cigs to remain overnight and slowly lift to
become VFR Sun afternoon.

SPECIFICS FOR KSTL/KSUS/KCPS: Heavy snow is lifting NE with
conditions improving slightly. Expect snow to largely come to an
end around 03z, but may be a bit sooner. MVFR cigs will linger
improving Sun afternoon. NW winds will gradually diminish becoming
light and vrb tonight as a surface ridge builds into the area.
Winds will become SE late Sun morning.
