What forecasters said that day

The local office's own words before this small craft 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 small craft advisory went out at Mar 9, 2:34 PM CST, 1 hour 5 minutes earlier.

Area forecast discussion, Mar 9, 2:34 PM CST, 1 hour 5 minutes before
Area Forecast Discussion
National Weather Service Green Bay WI
234 PM CST Thu Mar 9 2017

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Friday
Issued at 234 PM CST Thu Mar 9 2017

The latest rap analysis and satellite/radar imagery show a secondary
cold front dropping south into northern Illinois early this
afternoon.  Still have a fairly wide swath of mid-clouds across the
state behind the front, but clearing is slowly working south over
far northern WI and the Lake Superior region.  Looking upstream, a
very cold arctic high is building south into the northern Plains,
where temps are barely above zero.  As this arctic high continues to
build south, temps and wind chills are the main forecast concerns.

Tonight...A 1048mb arctic high pressure system will be building
southeast across the northern Plains and western Great Lakes through
the night.  As northwest winds strengthen, they will usher in a very
cold airmass to 25 below at 850mb over far northern WI.  The airmass
will be quite dry too, but should have lake effect snow showers
develop over western Lake Superior that should push into the snow
belt areas of north-central Wisconsin overnight.  The dry air should
limit the coverage area, southward extent, and possible accums to
under a half inch.  Elsewhere, mid clouds will be departing during
the evening, resulting in mostly clear and cold conditions
overnight.  Lows will fall into the lower single digits below zero
across the north.  Combined with a brisk northwest wind, wind chills
will likely fall to around 20 below for a couple hours.  Will issue
a sps to highlight the very cold wind chills.

Friday...The arctic high will continue to dominant the sensible
weather across the area.  Light lake effect snow showers will likely
continue over the far northern WI snow belts through the day.
Elsewhere, should be mostly sunny, breezy, and cold.  Temperatures
should range from 15 to 25 degrees below normal for the date.

.LONG TERM...Friday Night Through Thursday
Issued at 234 PM CST Thu Mar 9 2017

North-northwesterly flow will keep below normal temperatures in
place Friday night and through the weekend. Wind chills at night
are expected to dip into the negative teens in the north and
negative single digits towards the Fox Valley around Saturday
morning. A small chance of snow showers will linger on in the far
north through Sunday, but otherwise conditions through the weekend
will be quiet.

The storm system expected for late Sunday night and Monday
continues to be the primary concern for the extended period.
Models vary on the exact track of this system, with the Canadian
spreading snow across the region earlier than the GFS/ECMWF.
Models then agree that snow showers will overspread the region
Monday morning, but the variance in the tracks keep totals
uncertain. The GFS and ECMWF favor a storm track that could bring
in some lake enhancement along the shoreline and parts of east-
central Wisconsin during Monday afternoon. Snow chances are
expected to stick around through the night and into Tuesday
morning before moving out with the upper level trough during the
afternoon. A more quiet period then returns in the middle of next
week as temperatures return closer to normal by Thursday night.

.AVIATION...for 18Z TAF Issuance
Issued at 1048 AM CST Thu Mar 9 2017

A swath of mid-level clouds will depart later this afternoon or
this evening. Thereafter, mostly clear skies are expected
overnight and Friday with the exception of lake effect clouds and
scattered snow showers generally north of Rhinelander.
