Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
334 PM CDT Sat Apr 26 2025

.KEY MESSAGES...

- Potential for severe thunderstorms Monday night (risk level 4
  out of 5 in the west, risk level 3 in the east, except 2 along
  the lakeshore). Initial indications are that this activity
  will peak late Monday evening into the overnight with all
  hazard types possible.

- High temperatures near 80 degrees Fahrenheit are expected
  Monday, then cooling down toward the middle of next week.

&&

.SHORT TERM...

Issued 334 PM CDT Sat Apr 26 2025

Tonight through Monday morning:

High clouds are expected to increase late tnt via warm advection
aloft as an upper ridge approaches. Although there will be
ample time for temps to fall into the 30s via good radiational
cooling conditions. High pressure will then move ewd on Sunday
with lgt sely winds developing. Broken mid to upper level clouds
are expected from the morning into the early afternoon before
thinning and shifting nwd. Far se WI may remain partly cloudy
for the day. High temps will range from the lower 50s at the
Lake MI shoreline to lower to middle 60s elsewhere.

For Sun nt, cyclogenesis will move out of the central high
plains to the central Dakotas by 12Z Mon. South central WI will
be on the ern periphery of a strong sly low level jet over IA
and MN during the early morning hours. The LLJ axis will then
shift into wrn WI by 17Z with the accompanied thetae advection.
The warm, moist advection and elevated CAPE will bring chances
for showers and storms during this time with chances at 50-60
percent north and west of Madison.

Gehring

&&

.LONG TERM...

Monday afternoon through Saturday:

The models are in fairly good agreement with a 994 mb low over
the ern Dakotas at 18Z Mon tracking to north central Lake
Superior by 06Z Tue, with the cold frontal passage over srn WI
from 09-14Z Tue. The shortwave trough associated with the low
will be deamplifying over time as it tracks from the ern Dakotas
to Lake Superior. The warm sector will move into srn WI during
the afternoon and evening hours with capping initially expected
after any morning showers and storms.

The model qpf consensus produces QPF of one half inch or
greater mainly over west central WI to nw WI where the upper
dynamics will intersect the plume of sfc based instability. Thus
there is some uncertainty on the coverage of severe storms
farther to the south over srn WI for Mon nt. The timing would
appear to be late evening into the overnight. Overall will still
forecast 60-80 percent chances for rain as some PVA and 500 mb
height falls of 60-90 meters is forecast, and with the ability
of strong shear to organize a MCS. Strong deep layer shear of
50-55 kts and 0-3 km shear of 40 kts will combine with MLCAPE of
1500 J/kg to bring a meaningful severe storm threat to srn WI
especially over south central WI. All severe threats will be
possible including tornadoes given the strong low level wind
shear forecast, whether from a QLCS or supercells. Once again,
the coverage of the severe storms is the most challenging
aspect to the forecast at this time.

Wly winds and drying conditions will then take hold after the
frontal passage on Tue. Large high pressure will then gradually
shift across the region Tue nt-Wed with relatively seasonal
temps expected, but cooler near the lake.

More rain may then return Wed nt-Fri as a wave of low pressure
tracks from MO to the lower Great Lakes for Thu-Thu nt, which
may be followed by a shortwave trough out of the northwest for
Fri. High pressure to then follow for Fri nt-Sat. Temps for the
2nd half of the week will be at or slightly below normal.

Gehring

.AVIATION...
Issued 334 PM CDT Sat Apr 26 2025

VFR conditions this afternoon through Sunday evening.

Gehring

&&

.MARINE...
Issued 334 PM CDT Sat Apr 26 2025

High pressure around 30.4 inches over Lake Superior and Wisconsin
will move over Lake Michigan this evening. The high will be slow
to move away with light and variable winds forecast tonight and
Sunday.

Low pressure of 29.4 inches will then track from South Dakota
to northeast Minnesota Monday, then to Quebec by mid Tuesday
morning. Expect breezy southerly winds over Lake Michigan Monday
through Monday night. Southerly gales are possible, although there
will be a strong inversion over the cooler open waters, so there
is uncertainty that the very strong winds up to 50 kt just off the
surface will be able to mix down. The associated cold front will
cross Lake Michigan on Tuesday. Winds will diminish quickly
Tuesday night as high pressure around 30.2 inches moves into the
region.

A Small Craft advisory will likely be needed Monday and Monday
night from Sheboygan to Winthrop Harbor due to breezy south
winds and building waves. The hazardous conditions for small
craft may linger into Tuesday.
