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 29, 3:24 PM CST, 26 minutes earlier.

Area forecast discussion, Dec 29, 3:24 PM CST, 26 minutes before
Area Forecast Discussion
National Weather Service Des Moines IA
324 PM CST Fri Dec 29 2017

.SHORT TERM.../Tonight through Saturday/
Issued at 324 PM CST Fri Dec 29 2017

Snow continues across much of the northern and eastern portions of
the forecast area with some fzdz across the far south. Accumulations
so far across the north/east have been close to forecast amounts
with areas in the main heavier band from near Algona to Fort Dodge
to Marshalltown and Grinnell likely going to receive slightly higher
amounts than previously forecast. The sites listed above will likely
see amounts approach near 6 inches if not just above. Given the bulk
of the heavier snow having already fallen, and impacts not much more
with the area receiving 6 inches possibly versus 5 inches, and much
of the snow tapering off during the evening commute will stick with
the advisory and note upgrade to a warning. The back edge of the
snow is across SE SD at this time and should see significant push of
dry air into the state in the next few hours which should allow much
of snow to taper off from northwest to southeast with the strong
push of cold air moving in behind the cold front as well. In the far
south, getting low level saturation and no ice introduction so have
several reports of light freezing drizzle across the far southwest
into south central Iowa. Have issued an advisory for that area
through early evening. Any lingering precipitation past 00z should
have enough cold air aloft to change over to light snow or flurries.

Push of arctic air to come in tonight and will see winds pick up
some and shift around to the northwest. Temps will drop and skies to
see some clearing. Wind chills will fall as well with northern sites
dropping into the -30 range, and the southern sites dropping to
around -15 to -25 by Saturday morning. CAA to continue for much of
the day with little recovery in temps or wind chills through the day
Saturday. Will issue a wind chill warning for the north starting at
midnight tonight and an advisory for the southern half starting in
the early morning hours tonight. These will continue through the day
Saturday.

.LONG TERM.../Saturday night through Friday/
Issued at 324 PM CST Fri Dec 29 2017

Another weak wave to move through the region in northwest to
westerly flow pattern aloft. This system may bring a dusting to up
to an inch of snow to the southern half of the forecast area
Saturday night. Arctic high pressure will then build across the
region and into Iowa for Sunday into Monday with some of the coldest
air Iowa has seen in some time moving into the state. Air
temperatures will remain below zero for highs across much of the
state Sunday and Monday, with overnight lows in the -10 to -20
range. Record lows are likely New Year's Day morning with the arctic
blast continuing into Monday night. Winds will be in the 5 to 15 mph
range during this time further exacerbating the cold bringing wind
chill values down to -20 to -40 for much of the period Sunday into
early Tuesday. Therefore have continued the advisory/warning
combination that will be issued starting early Saturday through
Tuesday morning at this time. Much of the advisory area will need to
be upgraded into a warning for a period likely from late Sunday
through early Tuesday. This can be done in later shifts. There will
be a few brief time periods Saturday and Sunday that a portion of
the forecast area may warm above advisory criteria but they will be
short and not much warmer anyway, so will not mess around with those
brief time periods and keep the headlines out for the entire time.

As for the remainder of the period dry and cold conditions will
persist. H85 temps remain cold for Tuesday through Friday, with some
improvement from the frigid conditions as highs rise above zero and
lows mainly in the single digits below zero.

&&

.AVIATION.../For the 18Z TAFS through 18Z Saturday afternoon/
Issued at 1142 AM CST Fri Dec 29 2017

Low CIGS and VSBYS across the north today with the snow, which is
expected to taper off from northwest to southeast by late
afternoon/early evening. Low clouds to linger a bit longer with
winds shifting around to the northwest behind a strong cold front
late tonight. CIGS should go VFR at most locations toward sunrise
with gusty northwest winds expected for the remainder of the
period.
