.Bitterly cold conditions will continue this morning. Winds were
generally light, but occasionally edging into the 5 to 10 mph

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 Green Bay, WI wrote its last area forecast discussion before this wind chill advisory went out at Dec 25, 3:29 AM CST, 15 minutes earlier.

Area forecast discussion, Dec 25, 3:29 AM CST, 15 minutes before

329 AM CST Mon Dec 25 2017

Forecast discussion for routine morning forecast issuance

.SHORT TERM...Today...Tonight...and Tuesday
Issued at 329 AM CST Mon Dec 25 2017

Christmas morning will start out cold across northeast Wisconsin,
unfortunately things will not get much better throughout the day
with steady or slowly falling temperatures expected. Temperatures
are expected to stay below zero across north-central Wisconsin
today, with temperatures in the single digits above zero
elsewhere. Gusty westerly winds will cause wind chills to fall to
around 20 below zero across the western portion of the cwa today,
then across the eastern portion later this afternoon and this
evening.

850 mb temperatures will plummet to -25 to -30 degrees tonight,
this combined with mostly clear skies and daytime highs already
around zero or lower will push overnight lows well below zero
across the area Christmas night. Lows tonight are expected to
plummet to around 20 below zero across the north, with lows around
10 below zero across east-central Wisconsin and single digits
below zero near the lakeshore. Winds are not expected to be calm
tonight, which will cause wind chills to fall to 25 to 35 below
zero across the area tonight into Tuesday morning with some areas
across the north approaching 40 below.

Although temperatures are expected to warm a bit from tonights
chilly readings, highs Tuesday are expected to remain in the
single digits below zero across the area. West winds will keep
wind chill values in the 20 to 25 below zero range during the
afternoon hours on Tuesday.

These very cold temperatures will mean the Wind Chill Advisory
will remain in effect starting this morning across the west
through at least Tuesday, with the advisory starting this evening
across the east. Areas across the north will reach Wind Chill
Warning criteria late tonight and into Tuesday morning, therefore
will upgrade north-central Wisconsin to a Wind Chill Warning for
these times sandwiched between Wind Chill Advisories through this
evening and continuing late Tuesday morning into the afternoon
hours and beyond.

.LONG TERM...Tuesday Night Through Sunday
Issued at 329 AM CST Mon Dec 25 2017

A long-wave low pressure trough covers much of North America. The
trough will continue to dominate the weather pattern for the next
week. The trough will draw Canadian air into Northeast Wisconsin,
generating bitterly cold temperatures for several days. The
coldest conditions will occur through Wednesday with lows as low
as the teens below zero and high temperatures in the single
digits below zero in some areas. A slight increase in
temperatures is expected toward the end of the work week and an
accumulating snowfall is possible Thursday or Friday as the
trough flattens and carries some energy and moisture into our
region from the Pacific Northwest.
&&

.AVIATION...for 06Z TAF Issuance
Issued at 1142 PM CST Sun Dec 24 2017

An upper-level disturbance in concert with an arctic front will
move across the forecast area from the west to east overnight.
Scattered very light snow or snow shower activity is expected to
continue over most of the forecast area with primarily MVFR cigs
and perhaps some brief MVFR visibilities in the heavier snow
shower activity. Only a dusting of snow is expected at most. After
the arctic front passes toward daybreak, west winds will increase
to 15 to 25 kts with a few higher gusts. The gusty winds will
continue into the afternoon on Christmas Day. Broken MVFR cigs
early should give way to VFR conditions by afternoon.
