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 Sep 19, 11:49 PM CDT, 3 hours 19 minutes earlier.

Area forecast discussion, Sep 19, 11:49 PM CDT, 3 hours 19 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1149 PM CDT Wed Sep 19 2018

.UPDATE...

Thunderstorms are moving east into western and southwestern
Wisconsin at this hour. A gradual push to the east-northeast is
expected overnight.

The primary concern remains localized areas of heavy rain. A
widespread 1-2 inches of rain is expected, which shouldn't cause
too many issues, but localized areas of 3-4" aren't entirely out
of the question. Should these enhanced areas of heavier rain
develop, flash flood may become a concern in a few spots.

&&

.AVIATION(06Z TAFS)...

Convection will move into the region overnight. MVFR to IFR
ceilings can be expected with this activity, along with occasional
drops to IFR vis in and around the heavier thunderstorms.

Rain/thunderstorms will lift north of the area Thursday as a warm
front lifts across the region. Behind this front, southerly to
southwesterly winds will become quite gusty, with 15-20 knots
Thursday afternoon and evening. VFR will prevail Thursday
afternoon and evening.

&&

.PREV DISCUSSION... (Issued 943 PM CDT Wed Sep 19 2018)

UPDATE...

Convection has fired across Iowa, with a few small areas of
thunderstorms pushing into southern Wisconsin. This should be the
trend through the overnight hours, with a slow but steady eastward
movement to the storms. Heavy rain remains the primary concern,
though overall trends suggest that the heaviest rain will be
transient enough to preclude the need for a Flash Flood Watch at
this time.

MARINE...

Southerly winds will increase tomorrow across the lake as low
pressure strengthens over the Plains. Southerly winds are
expected to approach gales across the northern portion of Lake
Michigan tomorrow night, with gales continuing into Friday as
winds become westerly behind a cold front. Further south, winds
will be between 25 and 30 knots. A Small Craft Advisory will
likely be needed for the nearshore waters Thursday night and
Friday.

With the increasing winds, waves will build to 6 to 8 feet across
the open waters Thursday evening, reaching their peak across the
northern portions of the lake early Friday morning, with waves
between 10 and 12 feet expected.

High pressure will eventually build into the region over the
weekend, with much less impactful wind and wave conditions by
Saturday morning.

PREV DISCUSSION... (Issued 621 PM CDT Wed Sep 19 2018)

AVIATION(00Z TAFS)...

Variable flight conditions are in place across the area right now.
For the eastern terminals, VFR is prevailing behind the rain that
fell earlier this afternoon. Further west, an area of MVFR
ceilings has pushed into MSN, and will likely remain this evening.
It remains unclear right now whether these lower ceilings will
push further east with time, and if so, how far.

Thunderstorms are already developing at this hour across far
northern Iowa and southern Minnesota, and will push east into the
region after midnight. MVFR to IFR conditions are likely with this
activity late tonight into the first half of the morning tomorrow.
Once this precipitation moves through/dissipates tomorrow
morning, VFR will return to the area. However, south to southwest
winds will become quite gusty by afternoon with 20 to perhaps 30
knot gusts at times. This will continue through the afternoon as a
frontal boundary begins to approach the region from the west.

PREV DISCUSSION... (Issued 356 PM CDT Wed Sep 19 2018)

SHORT TERM...

Tonight and Thursday...Forecast confidence is medium to high:

An area of rain continues to push across southern Wisconsin this
afternoon. This should continue to decrease in intensity as it
moves east through late afternoon. Dry weather is then expected
for the evening hours into early tonight.

Attention will then turn to showers and storms that will likely
develop as a warm front lifts through later tonight into Thursday
morning. Could see a few stronger storms and some locally heavy
rainfall. Models are in decent agreement in focusing the
precipitation along and north of a Madison to Milwaukee line.

It should be dry late Thursday morning through the afternoon with
the warm front north of the area and the cold front well to the
west. It should get warm and humid tomorrow given this setup.
Could see places approach 90 toward the IL border given enough
clearing.

LONG TERM...

Thursday Night...Forecast Confidence is Medium.

Primary forecast challenge will be additional rain and severe
chances with the cold front passage.

As has been the trend the past day or so, the cold front arrival
has trended later, with its passage now slated to be late
Thursday night into the daylight hours of Friday morning.
Diurnally speaking, not an ideal time for severe. The 12z suite of
model output does indeed show a pretty sharp drop in CAPE across
the region heading into the overnight hours Thursday night. As
this occurs, model QPF sharply decreases. As a result there is
some uncertainty with the forecast.

There will be plenty of shear both in the deep layer and in the
0-3km layer, and forcing with the front should be potent enough
to maintain convection as it moves into the area Thursday evening.
As a result, convection that develops to our west and northwest
tomorrow afternoon should be able to survive as it moves into
southern Wisconsin. If a severe risk can be maintained, the best
opportunity would be during the evening hours and west of a line
from Fond du Lac to Madison to Darlington. Wind and hail are the
primary risks, though 0-3km shear will be strong enough to be
concerned about a tornado or two.

Any rainfall will be progressive enough (and waning) to preclude
any heavy rain risk.

Friday through Sunday...Forecast Confidence is High.

The front will clear southeastern Wisconsin by the mid morning
hours and cold advection will spread over the region. Temperatures
will be tricky given CAA and cloud cover. Will likely be a
situation of initially falling temperatures leveling out and then
a minor rise in the afternoon. Much of the day should be in the
60s, starting off in the lower 70s in the southeast before
dropping behind the front.

High pressure moves over the region Friday night into Saturday and
dominates our weather regime through the weekend. Lows will be in
the 40s and highs will be in the 60s to around 70 degrees.

Monday through Wednesday...Forecast Confidence is Medium.

Warm advection kicks in Monday, with modest moisture return. A
cold front is still slated to move into the region Monday night
into Tuesday and rain chances during this time frame remain
prudent. More questions than answers forecast wise heading into
the middle of next week as there are decent timing differences.
Fundamental pattern change across North America will begin to
take shape. The GFS is quicker to bring in an additional round of
rain and then sharply cooler temperatures. The ECMWF is about a
day later timing wise. Bottom line, sharply cooler conditions are
looking more likely during the latter half of next week.
