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 Oct 11, 9:54 AM CDT, 4 hours 46 minutes earlier.

Area forecast discussion, Oct 11, 9:54 AM CDT, 4 hours 46 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
954 AM CDT Sun Oct 11 2020

.UPDATE...
(Issued 953 AM CDT Sun Oct 11 2020)

Low level warm air and moisture advection will continue through
the afternoon across most of southern WI. Low level moisture
increases to around 5K feet. Small pockets of weak lift may be
just enough to set off a few very light showers or sprinkles.
GOES-16 5 minute mesoscale visible imagery showing some bumpiness
to the stratus over western areas into northern IL, where an
isolated -shra recently developed west of KRFD. For now, wl
continue small chance for sprinkles but may have to bump up to
isold -shra. Not really thinking much lake contribution as the
Delta T is pretty low. However convergence along the lakeshore and
upslope along the eastern ridges may also set off some patchy
drizzle or an isolated shower.

Southwest CWA on edge of more widespread stratus and the edge of
the cloud shield is moving north. Clouds may fill back in in this
area. May have to lower maximum temps farther east and north due
to clouds lingering most of the day and cool east winds.

.SHORT TERM...
(Issued 400 AM CDT Sun Oct 11 2020)

Today through Monday:

This morning we will see clouds pushing in from the south
associated with a moisture surge from the south. With these clouds
we could see some low level WAA and with sufficient low level
moisture we could see some drizzle this morning and possibly into
the afternoon especially with the short term models showing some
precip though there is some uncertainty especially with how
quickly the moisture mixes aloft because 700 mb is very dry.
Otherwise much of this afternoon and evening will be quiet.

The main concerns for this period will be overnight tonight
through Monday as a strong UL trough will push through with strong
UVM and plenty of moisture in the column. In the upper levels
plenty of PVA will be present with the upper level trough. The
lower levels are showing a distinct trough with a strong LLJ
around 50 kts ahead of the trough axis showing the strong theta-e
advection associated with this system. In addition, the surface
will have a strong frontal boundary pushing through in association
with the strong low pressure. Rain is thus certain with this
system with the bulk of it coming through in the overnight and
morning period and pushing out in the afternoon. This system will
also bring very gusty winds initially from the south prior to the
front coming through and then northwest after the front pushes
through. After this pushes system pushes through expect drier air
to quickly push in with skies potentially clearing by the
afternoon.

.LONG TERM...
(Issued 400 AM CDT Sun Oct 11 2020)

Monday night through Saturday:

The front on Monday should be well east of the area by evening
hours with winds staying out of the W/SW. A couple of quick moving
shortwaves will pass to the north of the region Tuesday/Wednesday.
Limited moisture return behind the Monday frontal passage should
keep clouds and any showers to the north of the region. However,
by Wednesday it does appear that moisture advection is enough to
bring a few spotty showers in the afternoon with the better
chances up north. Decent WAA both days will allow highs to push
the 70 degree mark in the south and mid 60s in the north. Looking
ahead at the extended and we are in for quite a change, so these
mild temps will be nice. The system on Wednesday will set the
stage for a more amplified trough to become established across the
eastern US. We'll be under a colder NW flow regime to round out
the week and this holds through the weekend and into next week.

Highs on Thursday drop into the 40s to lower 50s and we won't see
much change in highs through Sunday. Rain chances look to be
limited despite the various shortwaves moving through the flow
mainly due to drier air near the surface. It does look like we
may see the first widespread freeze of the season Friday and
Saturday mornings and imagine that a few Frost/Freeze products
will be needed later this week.

.AVIATION...
(Issued 953 AM CDT Sun Oct 11 2020)

Expect pockets of IFR ceilings to improve to MVFR through the
early afternoon across southern WI. Otherwise, widespread MVFR
ceilings should continue for much of the day. Increasing SSE low
level winds ahead of approaching cold front may cause low clouds
to erode for a time tonight and become VFR, however confidence low
on this scenario for now. Still expect a period of showers and a
few storms to move quickly across southern WI from late tonight
through Monday morning along passing cold front.

.MARINE...
(Issued 953 AM CDT Sun Oct 11 2020)

Bumped up sustained wind and wind gusts slightly for remainder of
today over the LM open waters as Mesabi Miner and several
lakeshore stations reporting gusts 20 to 25 kts. East winds will
remain gusty today and continue to slowly veer to the southeast as
high pressure in western Quebec continues to move to the east and
a cold front in the Plains moves eastward.

The persistent easterly winds will continue to generate choppy
conditions with wave heights mostly 3 to 6 feet. Hence the Small
Craft Advisory for the nearshore waters will remain in effect
through Monday.
