The episode as NWS DVN wrote it up.
A strong winter storm impacted much of southeast Iowa, western Illinois, and northeast Missouri. Widespread snowfall ranging between 5 and 10 inches of snow was reported in the hardest hit areas, with 1 to 4 inches surrounding and gusty winds to follow. This event started and ended as a snow event, as cold air was in place prior. With the gusty winds, blowing and drifting snow was observed, reducing visibilities and making it difficult to measure the snowfall. Just as this storm was moving out, very cold temperatures moved in, with wind chills between -15 to -30 felt.

.SYNOPSIS...
Issued at 404 AM CST Sat Jan 1 2022
Cold front has pushed well south of the cwa with much colder air
infiltrating on brisk northerly winds. Widespread rain and
leading edge storms extends from the Southern Plains through
the Ohio Valley with a plume of deep moisture ahead of an
upper level trough ejecting across the Plains. Snow bands are
developing back further northwest into parts of KS/CO/NE and
N MO with mid level frontogenetical forcing. The approaching
trough with embedded shortwave energy and the entrance region of
Midwest to Great Lakes jet will combine for a round of accumulating
snow today into tonight to begin the New Year.
&&
.SHORT TERM...(Today and Tonight)
ISSUED AT 404 AM CST Sat Jan 1 2022
Winter storm still on track to bring accumulating snow today
into tonight followed by bitter cold. Not many notable changes
to the forecast. The onset has been delayed a bit, but
overall still looking at snow developing south to north this
morning into early afternoon with the strengthening mid level
FGen response. This could be somewhat banded before large scale
ascent increases this afternoon into evening leading to widespread
snow. Snow will be moderate to heavy at times with some periods
of near 1 inch/hr rates in the heaviest bands with soundings
showing a deep DGZ in conjunction with the more robust lift
this afternoon/early evening. Liquid precip amounts forecasted
have come down some, and this seems reasonable given the
progressive nature of the trough and the deep moisture remaining
well removed to our south across the TX Gulf Coast, Lower
Mississippi Valley and Mid-Deep South. SLR's look to be above
climo west/northwest further in cold air (temps in single digits
and teens) and could be 15-17:1 or so at times... while SLR's
transition closer to climo southeast around 11-13:1 although some
bouts of higher ratios expected in the peak rates this afternoon.
Overall, this leads to a bit lower snow amounts but not a lot to
change messaging with still a general range of 2-8 inches
with the lower amounts favored north of Hwy 30 through Hwy 20 in
eastern Iowa. Meanwhile, the higher amounts are currently being
favored in an axis roughly from Fairfield to Sterling with the
deformation zone on the northwest side of the passing mid level
low to our south. Tighter pressure gradient will lead to wind
gusts to 35 mph from the north at times, with blowing and drifting
snow and resultant low visibilities making for greater impacts.
Headlines remain unchanged with a Winter Weather Advisory along
the Hwy 20 corridor, though start time pushed back a bit due to
the delay in onset. Areas of far northwest IL will need to be
monitored for a possible upgrade. Otherwise, a Winter Storm Warning
remains in effect through this evening. Again, impacts likely
delayed a bit and may not get going into the northern portions of
the warning/advisory area until midday/early PM. With the slower
onset we could see the snow linger a bit longer tonight, but
should quickly taper off by late evening and overnight as the
upper trough swings through. Then the next component of this
winter storm settles in, with bitter to dangerously cold wind chills
developing overnight through Sunday AM. Coldest wind chills
of 20 below to possibly approaching 30 below will impact portions
of E Iowa and northeast MO and have issued a Wind Chill Advisory
for these areas 06z-18z Sunday. Elsewhere, wind chills will be in
the range of 10 below to near 20 below.
.LONG TERM...(Sunday through Friday)
ISSUED AT 404 AM CST Sat Jan 1 2022
Sunday night will be very cold with the fresh snow cover and high
pressure ridge settling overhead. Looks like widespread sub-zero
lows with some areas around 10 below or colder, easily the coldest
night of the winter season thus far. Winds will be light, but
any puff given those ambient air temps will easily lead to wind
chills of 15 below to 25 below likely requiring additional wind
chill headlines.
High pressure departs Monday with warm advection leading to some
moderation of temperatures. Fresh snow cover however, will play
a pivotal role on just how much warming occurs. Best case would
likely be recovery closer to normal for early January with upper
20s/lower 30s for highs by Tuesday.
A clipper system looks to pass north of the area mid-week and
dislodge another chunk of cold air sending temperatures back
down below normal accompanied by brisk northerly winds.
Beyond, there's considerable uncertainty due to model differences
but it does look like another period of moderating temps
late week into next weekend with some precipitation potential.

.AVIATION...(For the 06Z TAFS through 06Z Saturday Night)
ISSUED AT 1105 PM CST Fri Dec 31 2021
Periods of MVFR/IFR clouds will persist overnight, although VFR
may return for a time at CID/DBQ as clearing shifts southward.
Heading into Saturday, aviation conditions will deteriorate to
IFR/LIFR as widespread snow moves in during the mid to late
morning from SW to NE. Steady snow is expected at all the
terminals with peak rates between 0.5 to 1" per hour, highest
south of DBQ. The snow will become lighter by the evening but
continue into Saturday night. Additionally, strong north winds of
20 to 30 kts will lead to significant blowing and drifting during
the day on Saturday and at night.

Snow, moderate to heavy at times, is expected to overspread the Outlook area from south to north this morning through midday, and continue into this evening before diminishing. Snow totals of 2 to 8 inches are expected across the Outlook area, with the lower amounts near the Highway 20 corridor in eastern Iowa, and the higher amounts focused near an axis from Fairfield, Iowa to Sterling, Illinois. Travel could be very difficult. Winter Storm Warnings and Winter Weather Advisories have been issued. Gusty winds up to 35 mph will also accompany the snow leading to blowing and drifting snow, reduced visibility and bitter winds chills. Winds chills of 10 below to 25 below zero are likely overnight Saturday night and Sunday morning, as the coldest air of the season arrives. A Wind Chill Advisory has been issued for portions of eastern Iowa and all of northeast Missouri. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY Very cold wind chills of 15 below to 25 below zero are expected Sunday night and early Monday morning. .SPOTTER INFORMATION STATEMENT...
