Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
946 PM CDT Mon Mar 22 2021

.UPDATE...
(Issued 945 PM CDT Mon Mar 22 2021)

The stationary front off to our north and west will become the
focus for additional rain overnight. Thus, most of southern
Wisconsin should remain dry for the rest of the evening. Latest
CAMs are picking up on drier mid-level air in place, which will
slow the arrival of the next round of rain expected tomorrow
morning. This, did delay the arrival and slow the northward
progression of the light rain expected expected to lift north
Tuesday morning.

Otherwise, still expect widespread rain to lift northeast across
southern Wisconsin late Tuesday afternoon and into Tuesday night.
Could be a few rumbles of thunder, but not overly excited given
the lack of steeper lapse rates aloft. Thus, did opt to keep
thunder mentions for Tuesday afternoon/evening at isolated.

.SHORT TERM...
(Issued 205 PM CDT Mon Mar 22 2021)

Tonight:

Low pressure in the central Plains will start heading northeast.
There will be some light showers possible with a northward moving
850/925 baroclinic zone. Seeing this trend our way from northwest
IL. All in all a good deal of cloud cover will prevail with mild lows
mostly in the 40s.

Tuesday through Tuesday night:

Closed mid level low lifts north/northeast this period, keeping a
negative tilt orientation and gradually opening up. The surface low
will be occluding with a corridor of lift associated with the DCVA
of the mid level feature. Best forcing will be in the afternoon and
evening with less forcing after midnight. Some limited elevated cape
so will keep the small thunder mention in place.

Wednesday:

Rather messy pattern continues with mid level cyclonic flow.
Cyclonic flow as well at the surface with showers looking likely.

.LONG TERM...
(Issued 205 PM CDT Mon Mar 22 2021)

Wednesday Night through Monday:

The early week system will continue to exit overnight Wednesday.
Looking at cooler temps and brief period of dry weather into
Thursday morning. Meanwhile, another upper-level trough is progged
to dig across the southern Plains/northern Mexico overnight and lift
northeastward, which may gain more of a negative tilt through the
day Thursday. This is expected to bring another chance at precip to
southern WI.

However, there continues to be disagreement between the model
solutions and ensemble members with the track, strength, and timing.
Similar to yesterday model runs, the 06z GFS/GEFS continue to be
faster in bringing the mid-level trough and dynamics through the
Midwest with the low tracking across central IL and into the eastern
Great Lakes through the day Thursday. But the latest 12z GFS/GEFS is
trending the low track further south. Nonetheless the faster track
seems to bring lighter precip across our CWA through the day
Thursday and ending earlier with the low deepening further east. On
the other hand, the 00z and 12z ECMWF/EPS along with the Canadian
continues to be slower, but a bit more aggressive solution with
better dynamics and the low tracking across southern IL into lower
MI overnight Thursday into Friday. The slower solution progs
cyclogenesis and deepening to occur further west compared to the
GFS, which will delay precip timing to later Thursday into early
Friday, increase amounts, and affect/determine precip type.

Regardless of the continuing model differences at this time, the
overall model/ensemble trends continue to show a potential for
increased precip chances across portions of southern WI Thursday
into Friday. Precip type and amount will be dictated by the low's
track, strength, and timing. However, there is a potential for some
wintry precip to be in the mix, especially overnight Thursday.
Some accumulating snow is not out of the question, especially
given some of solutions hinting at a stronger low. Will continue
to monitor trends and evaluate how the system evolves over the
coming days as a shift further east or south, such as with the
latest 12z GFS/GEFS solution, could limit our precip chances.

Otherwise, the unsettle pattern is likely to continue into the
weekend after a brief lull in activity late Friday into early
Saturday as mid-level ridge builds across the region. Then another
upper-level trough is expected to dig across the Northern Plains and
into the Upper Midwest late Saturday into Sunday bringing another
shot at precip. Quieter weather will be possible early next week as
models hint at ridging to build across the central CONUS.

.AVIATION...
(Issued 945 PM CDT Mon Mar 22 2021)

VFR conditions are expected through tonight, with much of the
light rain shower activity from earlier this evening coming to an
end. On Tuesday, MVFR ceilings will gradually fill in as deeper
moisture and warmer air advect into the region. There looks to be
a few rounds of rain, one mid/late morning which will be on the
lighter side and shouldn't cause much in the way of visibility
restrictions. Then, additional more widespread rain arrives late
Tuesday afternoon/evening, as area of heavier rain is expected to
lift northeast across southern Wisconsin. This will bring better
chances for IFR conditions later on Tuesday into Tuesday night.

Winds will be light tonight, eventually become southeast and
easterly during this TAF period. Tuesday afternoon, some locations
could see southeast to easterly winds pick up and become gusty.

.MARINE...
(Issued 205 PM CDT Mon Mar 22 2021)

A small craft advisory may be needed Tuesday night into Wednesday
due to a low pressure system riding north/northeast from the central
Plains. Not expecting gale conditions with this system.
