What forecasters said that day

The local office's own words before this winter storm warning 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 winter storm warning went out at Mar 8, 10:22 PM CST, 5 hours 1 minute earlier.

Area forecast discussion, Mar 8, 10:22 PM CST, 5 hours 1 minute before
Area Forecast Discussion
National Weather Service Green Bay WI
1022 PM CST Wed Mar 8 2023

Updated aviation portion for 06Z TAF issuance

.SHORT TERM...Tonight and Thursday
Issued at 258 PM CST Wed Mar 8 2023

Skies were mostly sunny across northeast Wisconsin with mostly
cloudy skies across portions of central and north-central
Wisconsin. Temperatures were in the middle 30s to lower 40s.

For tonight, skies should turn mostly cloudy across the entire
area. The snow across Minnesota will move east into Wisconsin but
much of that should dissipate as it reaches our area. Did
contemplate adding some flurries later this evening, but decided
to hold off based on the bufkit soundings suggesting a lot of dry
air near the surface. There appears there will be enough breaks
in the clouds for temperatures to drop across far northeast
Wisconsin. Did lower temperatures the greatest in this area. Lows
should range in the teens north to the lower to middle 20s south
and upper 20s at Manitowoc.

On Thursday, skies will be mostly cloudy. Snow, maybe mixed with
rain will move towards central Wisconsin late in the day. There
are some timing differences between the quicker NAM/ECMWF and
the slower Canadian/GFS. Took a blend of the model solutions for
precipitation timing which matched up well with surrounding
offices. Highs will be in the 30s.

.LONG TERM...Thursday Night Through Wednesday
Issued at 258 PM CST Wed Mar 8 2023

The main focus of the extended forecast will be the winter system
at the beginning of the forecast period, Thursday night through
Friday.

Thursday night through Friday...Snow will be moving into the
region at the beginning of the extended period, as a surface low
crosses central Illinois. Moisture and warmer air wrapping around
the northern end of the surface low will provide the primary
ingredients for snow production on the northern end, aided by the
LFQ and a mid-level shortwave aloft. Overall qpf has increased
slightly over the area with the latest model runs, bringing some
higher snow totals a little further north. However, snow-liquid
ratios provide a challenge as this snow does have the potential to
be on the heavier side, keeping accumulation at the surface
slightly lower than would be initially suggested. Thus, lowered
some of the snow ratios for the overnight period. Finally, short
term meso models have finally begun to pickup on the lake
enhancement potential for this system as winds turn to the
northeast. Delta-T values will be around 10 to 15 degrees, which
isn't the most impressive, but with the other dynamics at play
will certainly prove enough to bring some additional snow to the
lakeshore. All that said, uncertainty remains on exactly how much
lake enhancement will occur and whether the track will hold steady
over the next day and a half. Additionally, the 18 to 21 hour
duration of the snowfall, even if most of it will fall within 12
hours, makes the headlines a bit tricky. Forecast snowfall
amounts do have areas approaching 6 to 7 inches and some higher
amounts along the lakeshore are possible, but given the
uncertainty, decided to go with a high end winter weather advisory
at this time. There will be the possibility of a future upgrade
to a winter storm warning if future forecasts keep the current
storm track and the lake enhancement signal persists.

The snow will exit fairly quickly over the later portion of the
day Friday, bringing back quieter conditions for the early weekend.

Rest of the forecast...
The next chance for light snow will arrive on Sunday as a fast
moving shortwave crosses the area. A quick couple of inches are
possible before this shortwave exits the region. Models have
hinted at another quick round of snow for Monday, so retained the
pops from initial guidance for this snow as well. High pressure
then builds in for early next week, bringing back dry and sunny
conditions along with near normal temperatures.
&&

.AVIATION...for 06Z TAF Issuance
Issued at 1022 PM CST Wed Mar 8 2023

Good flying weather should continue through at least
mid afternoon Thursday. Middle clouds may produce light snow but
dry air below 8000 feet should keep precipitation from reaching
the surface.

Light snow and MVFR conditions could arrive west of a Rhinelander
to Oshkosh line by late afternoon Thursday as a winter storm
approaches from the southwest. Light to moderate snow and IFR
conditions are likely Thursday night through around noon Friday.
Ceilings will likely remain around 1,000 feet or above with the
visibility ranging from a half mile to a mile and a half in the
snow. The snow will diminish Friday afternoon.
