What forecasters said that day
The local office's own words before this winter storm 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 winter storm warning went out at Feb 16, 5:49 AM CST, 5 hours 1 minute earlier.

.SHORT TERM... (Through Late Thursday Afternoon)
Issued at 424 AM CST Wed Feb 16 2022
...A strong storm system will bring the potential for flooding,
severe weather, and a mix of winter weather impacts through
tomorrow...
Here are updated key messages regarding this upcoming significant
storm system to impact the region late Wednesday through Thursday:
1.) While models have come into better agreement with the track of
the system, though the remains some disagreement in the exact
amounts of wintry precipitation (snow, sleet, and icing amounts).
2.) Training of heavy rainfall and thunderstorms is likely across
portions of the area this evening through Thursday, generally
centric to I-44 in MO and I-70 in IL. These conditions could lead to
nuisance areal flooding and minor river flooding. Therefore, a Flood
Watch remains in effect for these areas.
3.) Significant wintry precip in the form of heavy snow, sleet, and
freezing rain: is most likely to occur across northeast Missouri and
west central Illinois late Wednesday night through Thursday
evening. The Winter Storm Watch has been been expanded to include
parts of central Missouri where a total amount of snow, sleet, and
freezing rain may cause significant impacts.
4.) Severe thunderstorms are possible, particularly over parts of
southeast Missouri into southwest Illinois, on Thursday morning into
early Thursday afternoon.
The latest water vapor analysis is showing that the upper low has
dropped into the southwest CONUS and the northern stream trough as
moved into the northern High Plains. There continues to be overall
agreement in tonight's guidance that the southwestern trough will
move through the Midwest just ahead of the northern stream trough on
Thursday. Ahead of this trough, rain will develop across the
northern part of the CWA late this morning and then spread south as
mid level ascent and low level moisture transport increases ahead of
the trough. Then rain will become widespread across the area this
evening as there will be strong mid level frontogenesis, a
coupled jet structure, and PWATS climbing about 1.0". In addition,
there will be a chance of thunderstorms over much of the southern
half of the area as MUCAPES will be up to 500 J/kg.
A cold front will enter the northern CWA this evening and move
slowly south. The front will be slowed as a surface low moves along
it, most likely across the southern CWA on Thursday in response to
the upper trough moving across the area. This will bring a round of
sleet and freezing rain north of the front before the changeover
to snow. In addition, there is good agreement that a deformation
zone will move across northeast Missouri and west central Illinois
on Thursday associated with the upper low that will be capable of
producing a round of heavy snow. There is still a wide range the
snowfall values in the ensemble guidance over the northwest CWA
owing to slight difference in the tracks of the deformation zone
and QPF amounts which is leading to uncertainty this close to the
forecast time.
There remains the potential for a few severe storms Thursday morning
and afternoon along the low track over southeast Missouri into
southwest Illinois. While MUCAPES will only be around 500 J/kg, low
and mid layer shear will be more that sufficient for a few organized
severe storms capable of producing damaging winds and a tornado
or two and possibly some large hail.
Britt
.LONG TERM... (Thursday Night through Tuesday)
Issued at 424 AM CST Wed Feb 16 2022
The trough will quickly exit the area on Thursday night leaving dry
weather through the weekend. Cold air advection and snow cover will
bring a cold night on Thursday night, but then expect moderation
over the weekend into early next week as a surface high passes
through the area causing low level flow to turn out of the
southwest. Another system will affect the area by early next week,
but it looks to be mainly rain at this point.

.AVIATION... (For the 12z TAFs through 12z Thursday Morning)
Issued at 530 AM CST Wed Feb 16 2022
Low level wind shear is expected at KUIN/KCOU/KJEF through mid
morning. Dry and VFR weather is expected through early afternoon
when scattered showers begin to develop at KUIN/KCOU/KJEF along
with high MVFR ceilings. Then rain is expected to develop this
evening, and will be moderate to heavy at times, with ceilings
falling below 2000FT AGL by late this evening and becoming IFR by
late tonight. Visibilities will be MVFR and possibly IFR at times.
Winds will remain out of the south at 10-20 knots with gusts to
20-30 knots. Winds will decrease late tonight.
SPECIFICS FOR KSTL:
Expect mainly dry and VFR conditions through 00Z before steady
rain develops this evening and becomes moderate to heavy at times.
Ceilings will drop below 2000FT AGL by late this evening and
becoming IFR by late tonight. Visibilities will be MVFR and
possibly IFR at times tonight into Thursday morning. Winds will
remain out of the south at 10-15 knots through late tonight with
gusts to 20-30 knots. Winds will decrease late tonight.
