National Weather Service Des Moines IA
820 PM CST Fri Dec 23 2022

...Blowing Snow and Dangerous Wind Chills Persist Through
Tonight...

Strong northwest winds will persist tonight with gusts to near
45 mph common. This will result in blizzard conditions over much
of the northern half of Iowa, especially in rural or wind prone
areas. Further south, some impacts from blowing and drifting of
snow will persist as well. Also, bitter cold temperatures and the
strong winds will result in dangerous wind chills of 25 to
40 below zero through Saturday morning. Once blowing snow and
blizzard conditions improve sufficiently, the Blizzard Warning
will be transitioned to Wind Chill headlines, otherwise, the
dangerous wind chills are covered by the Blizzard Warning.

What forecasters said that day

The local office's own words before this wind chill 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 wind chill warning went out at Dec 22, 11:44 PM CST, 3 hours 19 minutes earlier.

.DISCUSSION.../Tonight through Thursday/
Issued at 305 PM CST Thu Dec 22 2022

Key Messages:
- Blizzard conditions combined with dangerous wind chills will
  create life threatening conditions for anyone that ventures out
  tonight through Friday, particularly over northern/central Iowa
- Bitter cold through Saturday morning, then gradual upward
  temperature trend
- Light snow chances parts of Iowa Christmas Day

Details: The snow has pushed into eastern Iowa as of early this
afternoon with COOP and spotter reports showing snowfall was between
2 to 4 inches in most places. Several reports between 4 and 5 inches
came were received from around the Webster, Hamilton, and Boone
county area. The arctic front that brought this snowfall is over
eastern Lake Michigan and stretches to near Little Rock to near San
Antonio. The parent trough of this front is digging southeastward
toward the western Great Lakes while surface low pressure develops
over the Ohio Valley. As this surface front pulls away, the clouds
are also departing to the east leaving behind a clear sky over
western into central Iowa. Winds in the wake of the front have been
increasing with gusts between 25 and 35 mph this morning and that
has increased into the 30 to 40 mph range now. Temperatures continue
to fall and with the increasing winds, the entire area is solidly in
Wind Chill Warning criteria with most places at or below -35F.

With the fresh snow and these winds, GOES-East day snow fog RGB
show a widespread field of blowing snow, which has a bit of milky
appearance to it over western/central Iowa, eastern/central South
Dakota, eastern/central Nebraska, and Minnesota. Frankly, it is
amazing to see such a large area of blowing snow. Visibilities thus
far this afternoon in Iowa have generally bottomed out around a half
a mile with KEST (ASOS), KEBS (AWOS), and KCIN (AWOS) reporting
such. Recently, KCAV (AWOS) reached a quarter of a mile. We've also
seen social media reports around Pocahontas of quarter mile
visibility, drifting snow, and county plows being pulled off the
roadways. As the surface low moves into the eastern Great Lakes,
explosive deepening of this low will occur, which will increase the
pressure field between the eastern Great Lakes and a ~1050mb high
moving down the eastern spine of the northern Rockies. For Iowa,
this means winds will be stronger tonight and Friday then they have
been so far. Current forecast for wind gusts is toward the BUFKIT
mean mixed layer wind versus the top of the mixed layer, which are
impressive around 50 knots over northern Iowa and also shown in HRRR
runs. For now, peak gusts were kept between 40 and 50 mph after
midnight tonight into Friday evening, but will monitor trends in
case we need to trend towards the top of the mixed layer. With these
stronger winds continuing to loft snow, we continue to forecast
blizzard conditions tonight into Friday and the headlines are in
good shape. Those blizzard conditions will be most likely in rural,
open areas so if you are in a sheltered, city/urban location and it
doesn't look bad, do not be deceived.

While the blizzard conditions alone are a concern for personal
safety, the bitterly cold air with these winds will create wind
chills of -35F or lower across all of Iowa. Stealing from the
midshift's discussion, wind chills this low are uncommon and happen
on average maybe a few hours per year (10hr/yr at Estherville to
2hr/yr at Des Moines), so this is a somewhat rare, prolonged cold
scenario for Iowa. If you were to venture out tonight or Friday and
become stranded due to a vehicle break down, stopped in traffic due
to an accident, or go off the roadway due to poor visibility, these
wind chills would be dangerous and life threatening if exposed for a
short period. We don't use those words lightly or often, but that is
the current scenario that we see unfolding, particularly over
northern and central Iowa. Wind chills will generally be below -25
if not -30F or lower across the state through Saturday morning.
While the Wind Chill Warning conditions are currently included in
the Blizzard Warning and Winter Storm Warning, will need to issue a
separate wind chill headline once the other warnings end.

While the forecast is dry through Friday and Friday night, the RAP
shows a thin layer of saturation dropping into northern Iowa in the
afternoon and evening with little lift noted in cross sections. The
RAP and HRRR BUFKIT soundings show that the not fully saturated
profile warms (yes, warms) to near the lower end of the
-18 to -12F dendritic growth zone while at the same time further
drying. There is no ice introduction so we could see freezing
drizzle or perhaps flurries briefly over northern Iowa, but
confidence was too low to include it at this time.

It will remain blustery through Saturday as the trough and surface
low wrap up and move northeast into the Quebec province. With around
36 hours of blowing snow, crystals will have been fragmented down
and the relatively lighter winds should result in blowing snow being
not be as prevalent. There could still be streamers across roadways,
which could pose a travel risk. After Saturday morning, the coldest
period will be in the past with temperatures forecast to rise
gradually into next week.

The next chance for light snow will come from a clipper system that
looks to track through the region later this weekend. Moisture will
be limited and it will take top down saturation to overcome the dry
low levels. Cross sections do not show robust lift, but sufficient
for light snow. Compared to yesterday, the 100 member grand ensemble
is slower with the arrival of snow holding off until later in the
afternoon with it more tracking through southern Minnesota,
northeast half of Iowa, and southwest half of Wisconsin. So, a bit
of light snow with amounts around an inch possible in parts of the
state are possible Christmas Day.

.AVIATION.../For the 06Z TAFS through 06Z Friday night/
Issued at 1139 PM CST Thu Dec 22 2022

Main concern remains IFR/LIFR visby reduction for blowing snow for
the entire period and beyond. Gusty winds will also prevail
through the period, increasing at sunrise and peaking to near
50kts at sunset. Highest winds will be at eastern terminals. IFR
cigs should lift to MVFR by around 00z.
