What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Jan 20, 11:14 PM CST, 3 hours 17 minutes earlier.

Area forecast discussion, Jan 20, 11:14 PM CST, 3 hours 17 minutes before

Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1114 PM CST Mon Jan 20 2020

.UPDATE...

Fog has developed west of the area this evening, and while some
may still develop across southeastern Wisconsin, impacts are
looking to be increasingly minimal. Otherwise, a cold night is
ahead, with lows in the single digits away from the lake/MKE
metro.

&&

.AVIATION(06Z TAFS)...

Light and variable winds will prevail overnight before becoming
southwesterly on Tuesday. Expect some occasional gustiness by
Tuesday afternoon. LLWS will then develop Tuesday evening as a low
level jet pushes into the area.

Still watching the potential for some light fog to develop
overnight; if it does, it would mostly likely impact the Waukesha
and perhaps Madison terminals. Right now, chances for this taking
place are decreasing, but are not zero.

&&

.PREV DISCUSSION... (Issued 834 PM CST Mon Jan 20 2020)

MARINE...

Southwest winds will increase on Tuesday has high pressure moves
southeast of the lake. Gales will become possible Tuesday night
across the northern half of the lake, continuing through Wednesday
evening. A Gale Watch is in effect for the northern 1/3 or so of
the lake for this time.

For the nearshore, winds will begin to increase later tomorrow,
though will likely remain below Advisory levels until tomorrow
night. A Small Craft Advisory will likely eventually be needed
for late Tuesday night through Wednesday evening.

PREV DISCUSSION... (Issued 333 PM CST Mon Jan 20 2020)

SHORT TERM...

Tonight through Tuesday Night...Forecast Confidence is High.

The last of the low clouds are finally scattering out this
afternoon and skies should be clear tonight with high pressure
nosing in from the northern Plains. The only uncertainty is the
potential for some light fog to develop. Given low dewpoints and
dry air in place, opted to leave this out of the forecast. Temperatures
should fall into the single digits across southern WI tonight
with an expected inversion. Many models are leaning toward a
slightly warmer forecast, probably due to bias correction, so I
undercut the guidance.

Sunny skies will give way to mid level clouds moving in by Tuesday
evening. Highs tomorrow will be in the lower 20s, similar to
today. Lows Tuesday night will be more mild than tonight, with a
quick drop-off in the evening and then gradual warming overnight.

LONG TERM...

Wednesday and Wednesday Night...Forecast Confidence is Medium/High...

The next system is expected to start pushing in from the west
Wednesday along a frontal boundary with some influence from an upper
level shortwave. There remains some uncertainty with the timing as
the low pressure system pulls northeast but generally the western
half of the CWA should see some precipitation, likely snow. However,
accumulations are expected to remain light at this point.

Thursday Through Saturday...Forecast Confidence is Medium...

As the Wednesday system pulls out there may be a lull in the
precipitation as the next system pushes northeast Thursday into
Friday. There still remains plenty of uncertainty in this period
generally with the most of the uncertainty coming from inconsistency
across models in the forcing aloft. Mostly snow is expected for this
period but warmer temperatures may cause some mixed precip. The
system initially expected Friday night looks to have drifted
southeast in its track thus not impacting the CWA as much as
initially expected. However, there is still uncertainty in the
track of this system and we expect the track to continue to
change so we will continue to monitor how this system changes.

Sunday Through Monday...Forecast Confidence is Low...

Given the uncertainties in the system track Friday night into
Saturday, Sunday and Monday become very uncertain. Models show very
different solutions in the upper levels with vast differences in
forcing. Thus this period should become more clear as models begin
to more closely align as we get a better idea of what will happen
with the system Friday night into Saturday. However the period look
likely to remain dry at this point.
