Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1050 AM CDT Thu Oct 12 2023

.UPDATE...
(Issued 1050 AM CDT Thu Oct 12 2023)

Showers moving through southern Wisconsin this morning are riding
along the low to mid level frontogenesis band and WAA. These
light scattered rain showers are expected to lift north through
this morning and gradually weaken/diminish. CAMs are still hinting
at this which supports the small and quick moving upper level
ridge moving through today. Once this band of light rainfall has
moved through many areas can expect a period of dry weather before
the next round of rainfall moves in later today. The forecast is
still on track.

Patterson

.SHORT TERM...
(Issued 514 AM CDT Thu Oct 12 2023)

Today and Tonight:

Key Message:
	- Scattered showers along WI/IL border with mostly dry
	  conditions north of I-94 this morning.
	- Band of showers lift north through southern WI this
	  afternoon/evening with amounts generally below half an inch.

Line of showers extending across northern IA to northern IL/IN
anchored to the low-level WAA and frontogenesis band persist this
morning. However, most of the latest CAMs have this activity over
northern IL/IN diminishing through the morning as a weak mid-
level ridge setups over the area between the two upper-level
troughs. Southern WI is only experiencing light, scattered showers
along the WI/IL border from the morning activity and expecting it
to follow a similar trend. Thus expecting drier conditions
through the first half of the day and have trimmed PoP chances for
areas north of I-94 this morning. May still see some scattered
activity creep north of the Cheddar Curtain through the morning,
but have lowered PoPs for areas south of I-94.

Overall, there will be plenty of dry time across southern WI today
and it will not be a complete wash out, but expecting shower chances
to increase this afternoon through tonight.

Better shower chances for southern WI are expected through the
second half of the day between 21z-06z as the low-level WAA and
frontogenesis lift northward as the mid-level trough and surface
low push into the southern Missouri River Basin. Overall,
expecting this activity to be anchored to the low-level forcing
with a line of showers extending west to east across the area.
This activity is progged to redevelop and begin its track north
from the WI/IL border this afternoon through the evening before
stalling across central WI overnight.

Given the progressive nature of the line paired with the lingering
mid-level ridge, expecting rainfall amounts to be on the lower side
for this event. The 00z EPS, GEFS, and CMC ensembles along with the
HREF all have lower (<50%) probabilities of at least seeing half an
inch, but a consensus of seeing a few tenths of an inch at least
across much of the area. Also there are questions in how far east
the line will redevelop as CAMs have the heavier showers farther
west closer to the favorable upper-level dynamics upstream and HREF
probabilities reflect this trend as well with <30% chance of
rainfall exceeding quarter of an inch, especially for
southeastern areas of WI. Thus, areas east of a line from Elkhart
Lake to Beloit are likely to see lower end amounts ranging from a
few hundredths to a few tenths. While areas Northwest of the line
may see slightly higher amounts approaching a quarter of an inch
to half an inch. Once the line lifts north again likely stalling
across our central WI counties, through there looks to be another
window for some drier conditions tonight for south and
southeastern portions of the CWA before the bulk of this rainfall
moves in for Friday.

.LONG TERM...
(Issued 514 AM CDT Thu Oct 12 2023)

Friday through Wednesday:

Key Message:
	- Widespread, heavier rainfall Fri-Sat with amounts exceeding an
      inch and pockets of locally heavier amounts over 2 inches.
	- Windy conditions expected with this system through the
	  weekend.

Unlike today, Friday is looking more like a washout with widespread
rain developing/moving into the region through the morning and
lasting into Saturday. Expecting to see the bulk of the rainfall
from this event during this timeframe with lingering chances into
Sunday. As the mid-level trough pushes further east into the the
region, the surface low is progged to track across IA and across
northern IL and occlude. Southern WI will be positioned on the
northern extent of the low with a TROWAL overhead and paired with
ample moisture (PWATs +1.0 inch) and dCVA from the mid-level trough.
Thus there will be plenty of forcing to support widespread shower
activity through the day Friday into the weekend. Still cannot
rule out a few thunderstorms, but overall instability will be on
the lower side in WI.

Looking at rainfall amounts, there continues to be run-to-run and
even model agreement between the EPS, GEFS, and CMC ensembles of
seeing high probabilities (+80%) of at least inch from this round
Friday through Saturday across most of southern WI. Looking at
rainfall amounts during this 24 hour period to range between 1-2
inches and there is potential for locally higher amounts exceeding
2 inches. Areas along the lake have an increased chance of seeing
these locally higher amounts aided by the warmer lake temps and
onshore flow. Expecting to finally see showers chances diminish
later on Saturday, likely from west to east, as the trough and
occluded low push east. Total rainfall from this system (Wed-Sun)
is looking to range from 1.5-2.5 inches with pockets of locally
higher amount nearing 3 inches not out of the question depending
on location. So a much needed soaking rainfall event for southern
WI through the weekend.

Additionally with this potent system traversing the region,
expecting windy conditions to accompany the rainy weather. There is
higher potential of seeing wind gusts around 30-35 mph Friday
through Saturday.

Otherwise, the system kicks east into start of next week with upper-
level trough lingering over the eastern CONUS and high pressure
progged to build south across the Central Plains. This will likely
result in another cooler pattern for southern WI through the week.

.AVIATION...
(Issued 1050 AM CDT Thu Oct 12 2023)

Varying flight conditions are expected across southern Wisconsin
this morning. Ceilings are generally expected to be around 2-5kft
with the lower ceilings expected to accompany the light
rain/drizzle that is moving through today. This light rain/drizzle
could drop visibilities to around 3-5 SM as it move through. This
scattered line of rain is slowly moving northeast this morning and
is currently along a line from Lone Rock (LNR) to Madison (MSN) to
Kenosha (ENW). Terminals located in the northeast corner of our
forecast area are likely maintain VFR conditions through the rest
of the morning and into the afternoon. Once the rainfall has moved
through ceilings should come back up a bit toward 5-6 kft. A brief
period of dry weather is expected after this line of showers has
moved through. With the rainfall chances increasing again this
evening into tonight. Heading into Friday morning, rainfall is
expected across southern Wisconsin. Rainfall will be heavy at
times Friday.

Easterly winds are expected to through the period.
As the approaching low pressure system gets closer to the state,
winds are expected to increase and become gusty.

Patterson

.MARINE...
(Issued 514 AM CDT Thu Oct 12 2023)

Low pressure will continue to slowly track eastward across the
Central Plains today. A warm front extending ahead of it has pushed
into IL and stalled just south of Lake Michigan. As a result,
northeasterly winds prevail across the northern half and gusty
easterly winds across the southern half of the lake. Will continue
to see the low moves east, but is expected to weaken as to moves
over northern IL through the day Friday. However, expecting
northeast to easterly winds to increase Friday through Saturday as
the low traverses eastward along the far southern portion of Lake
Michigan. There is still a potential for easterly gales and high
waves ahead of the low's passage along with thunderstorm chances on
Friday. But the better gale chances will be on the backside of the
low later Friday into Saturday. The system will linger through the
remainder of the weekend before exiting east by the start of next
week, but stronger northerly winds are likely to persist.
