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, 10:59 AM CST, 1 hour 3 minutes earlier.

Area forecast discussion, Jan 11, 10:59 AM CST, 1 hour 3 minutes before
Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1059 AM CST Sat Jan 11 2020

.SHORT TERM...  (Through Late Sunday Afternoon)
Issued at 355 AM CST Sat Jan 11 2020

Early this morning, an upper longwave TROF continued to reside over
the western CONUS, with southwest flow aloft over our region.  The
core of a strong storm system was over north-central and northeast
Texas crossing the Red River heading into Oklahoma.  At the surface,
a strong cold front has advanced to the far southeastern portions of
the forecast area, from eastern Illinois to southeast Missouri.
Temperatures have dropped fast behind the front into the 20s and
30s, with sub-freezing temps already reaching just west of
Quincy to Columbia, with temperatures still hovering around 60 ahead
of the front.  The radar mosaic shows a solid swath of
precipitation, with heavy rain now shifting more to the southeast of
the forecast area.  Fortunately, where the atmospheric column now
supports freezing rain/drizzle, the precipitation intensity is much
lighter but it has been ongoing in northeast Missouri and now into
portions of central Missouri.

With the flooding now being handled through Warning products, the
Flash Flood Watch has been cancelled.

The focus now turns towards wintry precipitation.  Cold air at the
surface has advanced more quickly than previous guidance was showing
and at this rate, the freezing line is now expected to work through
the STL metro area and southeast MO this afternoon with temperatures
dropping into and then remaining in the 20s for areas north and west
all day.

The main items of the forecast remain the same.  Precipitation
will become more spotty this morning as cloud ice becomes lost
across the forecast area and this will keep much of the
precipitation as rain or freezing rain/drizzle depending on where
the freezing line is at the surface, but through noon, this should
remain to the northwest of the STL metro area.

The core of the strong storm system will approach and then move
through our region from midday through this evening from west to
east, and this will re-introduce cloud ice back into the column and
bring an end to the freezing rain/drizzle and switch precipitation
quickly to a rain vs. snow scheme with snow eventually winning out
as colder air continues to press into the area.  Anticipated SLRs
were kept on the low side with sustained surface winds of 15kts or
higher keeping any snow well settled/drifted and a limited window
for snow to occur.  Despite this, a 2-4" swath of snow is expected
for the Warning area with up to 2" possible in the Advisory area.
The biggest change was a bit more snow for the STL metro area, where
up to an inch is expected in the western suburbs to a dusting or
less in Metro East.  Ice accretion from freezing rain is roughly the
same, with 1 to 2 tenths additional ice in the Warning and up to 1
tenth additional ice in the Advisory area, and no ice expected
elsewhere.

Precipitation is expected to rapidly exit this evening from
southwest to northeast this evening.

Some sun is finally expected for Sunday with seasonable temps, with
maxes in the 30s north of I-70 and around 40 for areas south.

TES

.LONG TERM...  (Sunday Night through Friday)
Issued at 355 AM CST Sat Jan 11 2020

Above normal temps already return for Monday and continue
through Wednesday before colder air works in for late week.  Another
system will edge our region on Sunday night and could provide a
chance for light snow for areas in northern MO and central IL, and a
better looking system for Friday could provide another snow
opportunity as it tries to couple with an intrusion of colder air.

TES

&&

.AVIATION...  (For the 18z TAFs through 18z Sunday Afternoon)
Issued at 1037 AM CST Sat Jan 11 2020

An area of snow over western MO will shift eastward into the taf
sites this afternoon with visibilities likely dropping down to 1-2
miles in snow and fog. This snow will shift east of the taf sites
later this evening. The cloud ceilings will remain below 1000
feet this afternoon, but should improve into the MVFR category
late tonight. Strong and gusty northwesterly winds will diminish
this evening as the surface pressure gradient relaxes with fog
developing late tonight.

SPECIFICS FOR KSTL: Intermittent light rain and drizzle will
continue early this afternoon, then an area of snow over western
MO will shift eastward into STL late this afternoon with
visibilities likely dropping down to 1-2 miles in snow and fog.
This snow will shift east of STL by 02Z Sunday. The cloud
ceiling will remain below 1000 feet this afternoon, but should
improve into the MVFR category late tonight. Strong and gusty
northwesterly winds will diminish this evening as the surface
pressure gradient relaxes with fog developing late tonight. Will
likely see improvement into the VFR category by late Sunday
afternoon with the surface wind becoming southeasterly.
