What forecasters said that day

The local office's own words before this flash flood watch 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 flash flood watch went out at Aug 28, 3:40 AM CDT, 28 minutes earlier.

Area forecast discussion, Aug 28, 3:40 AM CDT, 28 minutes before
Area Forecast Discussion
National Weather Service Green Bay WI
340 AM CDT Tue Aug 28 2018

Forecast discussion for routine morning forecast issuance

.SYNOPSIS...
Issued at 335 AM CDT Tue Aug 28 2018

Still very humid with more showers and thunderstorms today--ending
from northwest to southeast tonight. Cooler and drier Wednesday.

Throughout the period, the upper pattern will be dominated by
ridging over the eastern Pacific which will gradually retrograde
westward, and downstream troughing over western into central North
America. The weather across the forecast area will primarily be
affected by oscillations in the amplitude of the pattern.

Very humid conditions will persist today, then cooler and drier
air will spread across the area Wednesday. Readings should return
to AOA normal thereafter. Another significant round of
thunderstorms is expected this afternoon and evening. That combined
with additional chances later in the period should result in above
to much above normal precipitation totals.
&&

.SHORT TERM...Today...Tonight...and Wednesday
Issued at 335 AM CDT Tue Aug 28 2018

Ongoing convection continues across the southern tier of counties
in the forecast area. The storms continue to backbuild, but there
has been a decrease in the amount and intensity of redevelopment
over western Wisconsin during the past hour or so. That's likely a
result of the LLJ slowly veering westerly and it has been picked
up on by the short-term models. So expect the ongoing convection
to wane toward daybreak.

There should be a lull in the precipitation across the area during
the rest of the morning. However, a cold front will slowly sag
southeast across the area today. The front combined with
increasing large scale forcing from mid-level FGEN and divergence
in the RRQ of an upper speed max in the Lake Superior region will
lead to another round of convection this afternoon and evening.
Severe storms are possible, through widespread clouds will
probably limited destabilization and somewhat hold back the severe
threat. Damaging wind gusts will be the primary severe hazard.

Of greater concern is the flooding potential. Two rounds of heavy
rain have already fallen across the southern part of the area--
Monday morning and again late Monday evening and overnight. This
is the area at greatest risk of receiving additional heavy rain as
the large scale forcing interacts with the very moist air mass
(PWATs AOA 2") across the area. The greatest potential for
flooding will be from noon to midnight, and over the southeast 1/3
of the forecast area. That period/area needs to be covered by a
Flash Flood Watch. The complicating factor is the lingering
portion of the current watch, and the fact there is some
urban/small stream flooding ongoing. Considered various options
for how to manage the headlines, and finally opted to extend the
current FFA for the southern tier to midnight, and have a new FFA
for Outagamie/Brown/Kewaunee begin at noon. Some adjustments to
timing and areal extent may be necessary as convective trends
later today become clearer.

.LONG TERM...Wednesday Night Through Monday
Issued at 335 AM CDT Tue Aug 28 2018

Models are in general agreement with an upper ridge parked over
the southeast CONUS and a broad upper trough from the Pacific
Northwest into the northern Plains. A series of shortwaves will
eject out of this trough and move east-northeast which would
impact northeast WI Friday/Saturday and again Monday. Temperatures
are expected to be below normal through Thursday, then rise above
normal thereafter.

High pressure is expected to stretch from the western Great Lakes
into southeast Ontario Wednesday night, bringing mostly clear
skies, light winds and cool conditions to northeast WI. Would
anticipate at least patchy fog across the area due to all the rain
from previous days. Min temperatures to range from the upper 30s
to lower 40s north-central WI, upper 40s to lower 50s across
east-central WI. This high pressure farther to the east, allowing
for a return flow to gradually develop over WI. The return of
south-southeast winds and mostly sunny skies will provide an
uptick in temperatures with readings in the middle to upper 60s
near Lake MI, upper 60s to lower 70s elsewhere.

As a mid-level shortwave moves through the southwest flow aloft
into the Upper MS Valley, increased forcing from this feature,
combined with WAA, should at least bring an increase in clouds to
central WI later Thursday night. The air mass over northeast WI
still looks too dry to support any precipitation. Min temperatures
will not be as cool as Wednesday night with readings in the lower
50s north, middle to upper 50s south. This shortwave rides
northeast into the western Great Lakes region on Friday and
combined with increasing instability (steep mid-level lapse
rates), will lead to the next chance for showers/thunderstorms
into northeast WI. Depending upon how unstable we can get, some of
these storms could become strong and will need to be watched for
severe potential. Max temperatures on Friday to be in the lower
70s north-central/near Lake MI, generally middle 70s everywhere
else.

Additional showers and thunderstorms are expected Friday night
into Saturday as a cold front approaches/eventually moves through
the region. Depending on rainfall amounts, will have to watch for
any flooding potential as the ground will likely be saturated. Max
temperatures on Saturday to be in the middle 70s north-central/
near Lake MI, upper 70s to around 80 degrees far northeast WI/
south. Any precipitation left over east-central WI Saturday
evening should end as an area of high pressure builds into the
region later Saturday night. Skies will gradually become mostly
clear and as north-northwest winds become light overnight, cannot
rule out patchy fog. The high pressure is forecast to already be
shifting east on Sunday, but still have enough influence to keep
our forecast dry through the day. Max temperatures Sunday to be in
the lower to middle 70s near Lake MI, middle to upper 70s for
inland locations.

There are issues among the models as to when a warm front will
being lifting north into WI early next week. The ECMWF is faster
than the GFS with elevated showers/thunderstorms reaching central/
east-central WI by 12Z Monday. The GFS does not bring any
precipitation into the forecast area until Monday afternoon. For
now, have followed the model consensus which leans toward the
faster ECMWF. Max temperatures for Monday to generally be in the
middle to upper 70s.
