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 Des Moines, IA wrote its last area forecast discussion before this winter storm warning went out at Jan 9, 11:28 PM CST, 4 hours 29 minutes earlier.

Area forecast discussion, Jan 9, 11:28 PM CST, 4 hours 29 minutes before
Area Forecast Discussion
National Weather Service Des Moines IA
1128 PM CST Thu Jan 9 2020

...Updated 06z Aviation...

.DISCUSSION.../Tonight through Thursday/
Issued at 349 PM CST Thu Jan 9 2020

Active forecast period awaits Iowa with multiple system affecting
the state over the next week.  However, the main focus lies with the
system expected to affect the area Friday afternoon into Saturday
evening.  Models have been slowly converging on an overall solution
with confidence gradually increasing with the forecast.  Currently,
very warm to record breaking temperatures exist across much of
central Iowa with gusty west to southwest winds.  However, change is
arriving in northwest Iowa as a cold front has pushed into that
corner of the state.  This boundary will sweep across the state
tonight with much colder air arriving by Friday morning.

Main focus then turns to a big round of forcing arriving Friday
afternoon and persisting through the evening. NAM has been by far,
the most aggressive with frontogenetical forcing by late afternoon
and evening across central Iowa.  Isentropic lift is also very
impressive with widespread precipitation across central and
southern Iowa by 00Z. However, the bulk of GEFS and Euro output is
not nearly as strong with QPF across central Iowa during this
time with the bulk going into the broad band of showers and
embedded storms in Missouri and Illinois. That being said, there
is a noted northwest shift of overall QPF associated with the
Friday afternoon/evening event which does increase snowfall in
central Iowa with a bit more icing in southern Iowa as a warm nose
aloft moves into the south. Amounts near I80 have increased into
the 1-3" range with higher amounts to the southeast. In addition,
up to a tenth of an inch or so of icing occurs near the Missouri
border where soundings indicate the warmer air aloft. By later in
the evening, precipitation is forecast to end as forcing subsides
with snow and any freezing pcpn dissipating into the overnight.

The upper low and associated mid level forcing are then expected to
approach the southeast half of the state into Saturday with forcing
ramping up once again.  At this point, cold air will be deep enough
to ensure that only snow falls on Saturday as the deformation zone
passes across the southeast/east during the day.  Additional
accumulations are expected during this time with heaviest amounts in
the southeast portions of the forecast area.  The combination of
both precipitation episodes is sufficient to warrant a watch
headline across southeast portions of the forecast area for late
tomorrow into Saturday night. Of course, should an even more
northwest track become apparent, the headlines may need some
additional westward adjustment as necessary.

Of additional concern is the timing of precipitation arrival on
Friday.  At this time, snow will be intensifying during the
beginning of the evening commute on Friday afternoon with the
precipitation continuing throughout the evening.  This may produce
difficult travel conditions when most drivers are heading home at
the end of the work day.

The forecast beyond this period continues to appear active with a
series of waves passing through Iowa every 24-36 hours.  As
previously mentioned in the past few discussion, the timing of these
waves is difficult to predict at this point with the main take-away
that additional light snow events are expected at various times from
late in the weekend through the middle of next week.

.AVIATION.../For the 06Z TAFS through 06Z Friday night/
Issued at 1124 PM CST Thu Jan 9 2020

Quiet weather overnight. VFR conditions will continue through
early Friday afternoon. Cloud cover will begin to increase mid
through late afternoon. Snow showers expected to spread across
Iowa Friday Night. IFR visibilities possible at DSM during time
of heaviest snow. As of the 06z TAF issuance, there is still some
uncertainty regarding the snow rates and exact impacts on
visibility. Recent model trends indicate a more robust snow band.
Most of these impacts will occur in the last 6 hours of the 06z
TAF period.
