What forecasters said that day

The local office's own words before this wind chill advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Milwaukee, WI wrote its last area forecast discussion before this wind chill advisory went out at Dec 24, 1:33 PM CST, 17 minutes earlier.

Area forecast discussion, Dec 24, 1:33 PM CST, 17 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
133 PM CST Sun Dec 24 2017

.SHORT TERM...Rest of this afternoon and tonight...

The shortwave responsible for today's snow will exit the region
this afternoon, bringing an end to the snow. Behind that, we'll
see a secondary surge of cold air push into southern Wisconsin on
Christmas morning. Good consensus amongst the models showing this
push of cold air squeezing out a little bit of snow on Christmas
morning as it moves through. High-res guidance focuses on a
narrow NW to SE corridor from roughly Sauk to Walworth County,
and only drops a couple of hundreths of QPF in that area. The
exact track may change somewhat, but confidence is medium to high
the we'll see a narrow swath of light snow.

.LONG TERM...Christmas Day through next weekend...

Forecast Confidence...Medium to High...

Temperatures will fall for much of the day on Monday, eventually
falling below zero for nearly all of the forecast area Monday
night into Tuesday morning. On Tuesday, temperatures only look to
recover to the low single digits at best, and will fall below zero
for most, if not all of the area again Tuesday night/Wednesday
morning. Compounding these temperatures will be rather persistent
west to northwest wind, with gusts on Christmas Day near 30 MPH,
and remaining in the 15-20 MPH range Christmas night and Tuesday.
The combination of cold and wind will yield dangerously low wind
chills, with readings between -15 and -30 degrees from Monday
evening through Wednesday. A Wind Chill Advisory has been issued
for most of the area for this time. It is possible that the
Advisory may eventually need to be expanded down to the Illinois
state line.

A very slow moderation in temperature is then expected for the
rest of the week, but highs will only be in the upper single
digits and teens, with lows not far from zero.

Our next chance for precipitation looks to be in the
Thursday/Friday timeframe, with most extended guidance showing
some sort of system affecting the Great Lakes region. However,
considerable differences remain regarding potential snow amounts,
as well as timing. This will be something to keep an eye on over
the next few days.

&&

.AVIATION(Afternoon TAF Update)...

Snow will end from west to east over the next couple of hours,
with conditions improving to VFR by this evening. Rather gusty
west winds and cold temperatures are expected on Christmas Day.

&&

.MARINE...

Winds will become gusty from the west starting this evening,
continuing through Christmas Day. Winds will peak during the
afternoon hours on Christmas, when gusts in the nearshore waters
may approach gale force. A Small Craft Advisory is in effect from
this evening through Tuesday morning. In addition to the wind,
waves are expected to approach 4 ft near open waters on Monday.

Winds will decrease Tuesday, and should remain fairly low through
mid week. Winds/waves may increase again toward the end of the
week or into next weekend, as another storm system approaches the
region.
