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 Feb 26, 5:17 AM CST, 8 hours 19 minutes earlier.

Area forecast discussion, Feb 26, 5:17 AM CST, 8 hours 19 minutes before
Area Forecast Discussion
National Weather Service Green Bay WI
517 AM CST Sun Feb 26 2023

Updated aviation portion for 12Z TAF issuance

.SHORT TERM...Today...Tonight...and Monday
Issued at 321 AM CST Sun Feb 26 2023

Satellite imagery showed mostly clear skies across the region
early this morning with a ridge of high pressure over the western
Great Lakes region. Mostly sunny skies are expected today as the
high pressure slides off to the east. Highs today are expected to
mainly be in the upper 20s to lower 30s.

A low pressure system developing over the central Plains will lift
northeast towards south Iowa late tonight, then continue tracking
east near the Wisconsin and Illinois border on Monday. This system
will bring a wintry mix of weather to the region, with a warm
layer aloft starting the precipitation off as freezing rain late
tonight. Precipitation will then become a mix of freezing rain,
sleet, and snow Monday morning as colder air gets pulled in from
the north, with an eventual changeover to mainly snow Monday
afternoon with some rain possible across central and east-central
Wisconsin. The timing of the system has come in later this run,
with precipitation not starting until late tonight versus just
after midnight per previous runs. In addition, snowfall amounts
across north-central Wisconsin have come in a bit higher this run,
with the possibility of reaching 6 inches in 12 hours a tier north
of the current watch. Freezing rain amounts are still around one
quarter of an inch across much of central Wisconsin. Across the
rest of the area icing amounts are generally 0.1 to 0.2 inches
with snowfall amounts of2 to 4 inches. Given all these factors
will push back the start of the watch across central Wisconsin 3
hours and include another tier of counties north to the UP border
across north-central Wisconsin with the current Winter Storm
Watch. Areas not in the current Watch would likely see a Winter
Weather Advisory if the current trends hold from the 00z models.

Lows tonight are expected are expected to range from the middle
teens across the north, to around 20 across central and east-
central Wisconsin. Highs Monday are expected to range from around
30 across north-central Wisconsin to the middle 30s across east-
central Wisconsin and portions of central Wisconsin.

.LONG TERM...Monday Night Through Saturday
Issued at 321 AM CST Sun Feb 26 2023

Fairly progressive fast moving flow

Monday night into Tuesday...
The last of the wintry system from the short term will work its
way out of the region Monday evening, with quieter conditions
expected to return overnight. Weak surface high pressure will then
establish itself over the region due to the arriving colder air
from the west. Expect a quieter and sunny day for most of Tuesday,
with high temperatures in the middle 30s to lower 40s.

Tuesday night through Wednesday...
The next chance for precipitation will be a fast moving shortwave
that will arrive in the middle of the week. Models still diverge
on the exact timing, from a more aggressive late Tuesday night to
a slower Wednesday morning timing. Currently this system is
forecast to predominantly snow, but a lack of ice aloft could see
brief drizzle or freezing drizzle mix in at times. Most of the
area will likely see at least a dusting of snow, with higher snow
totals possible in northern Wisconsin. Amounts up to 2 to 4
inches will be possible near the Upper Peninsula border with the
current forecast, but this may change if the timing becomes more
defined as this will likely be a relatively fast event.

Rest of the forecast...
Another strong upper trough will dig into the southwestern US
during the late week, developing a strong low pressure system that
will cross CONUS into the Ohio River Valley. At this time, this
system will miss our area to the south, so quiet conditions are
expected for the rest of the extended.

.AVIATION...for 12Z TAF Issuance
Issued at 516 AM CST Sun Feb 26 2023

VFR conditions are anticipated through the TAF period, with
increasing high clouds expected this afternoon and evening. LLWS
will diminish toward daybreak.

A winter storm will bring heavy mixed precipitation to the region
late tonight into Monday, along with rapidly deteriorating flight
conditions and possible flight delays or cancellations.
