Area forecast discussion, Apr 29, 10:18 AM CDT, 4 hours 36 minutes before

Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1018 AM CDT Thu Apr 29 2021

.UPDATE...
(Issued 1018 AM CDT Thu Apr 29 2021

The rain showers associated with the system passing to the south
of Wisconsin have gradually moved out of southeastern Wisconsin
this morning. Cloudy skies will continue as a cold front
approaches from the northwest. A line of scattered showers and
thunderstorms is expected to move through the area along the cold
front. The forecast is still on track for today.

Patterson

&&

.SHORT TERM...
(Issued 250 AM CDT Thu Apr 29 2021)

Today through Friday:

Precip shield associated with system passing to our south is
pretty much staying south of the WI/IL border so have removed the
pops in the far south for this morning. The overall mid level flow
shows an amplifying trough with a surface cold front swinging through
this afternoon. Will keep the shower chance going and add a little
thunder as well. Seeing some convective potential with a few hundred
J/KG with decent low level lapse rates/inverted-v soundings. This
activity should exit the east early this evening. Cold advection
increases later in the evening into early Friday. High pressure
will then settle in for Friday with an onshore flow developing.

Collar

&&

.LONG TERM...
(Issued 250 AM CDT Thu Apr 29 2021)

Friday night through Wednesday:

Southerly return flow will kick in Friday night, keeping temps
mild in the upper 40s to near 50 across the western half of the
forecast area. Temperatures further east will have more time to
cool before the southerly winds develop, with lows in the low 40s.
It's likely that lows will be met late Friday evening, with
temperatures then rising during the pre-dawn hours on Saturday.

This will set the stage for a warm and very windy Saturday.
Temperatures will reach the mid to upper 70s to around 80.
Southwest winds will be very gusty, with 30 to 40 MPH gusts at
times. The strongest winds will be across southeastern Wisconsin.

The daytime hours on Saturday look to be dry, with scattered
showers and thunderstorms developing north of the area Saturday
night. These may start to slip south into the area as the surface
front starts to retreat back to the southwest late Saturday night
into Sunday morning.

The surface front will likely stall somewhere across the region
on Sunday, with scattered showers and thunderstorms in the
vicinity of the front. Temperatures on Sunday will be highly
dependent on frontal position, with upper 70s/near 80 south of the
front, and 50s to perhaps low 60s north.

Rain chances increase Sunday night into Monday as shortwave energy
arrives from the west and southwest, with decent rain chances
persisting into Monday. The front is expected to eventually push
south of the area early to mid week, likely taking the bulk of the
rain chances with it (still lots of uncertainty with regard to
timing of this, however). Temperatures through mid week will be
cooler, with 50s and 60s looking probable.

.AVIATION...
(Issued 1018 AM CDT Thu Apr 29 2021)

The mostly MVFR to VFR ceilings are expected to continue until
this afternoon. Southern Wisconsin is split by rain showers to our
south in Illinois and the approaching cold front in Northern
Wisconsin. Ceilings are expected to be more widespread MVFR to IFR
as the cold front moves through this afternoon. There will be
some scattered rain showers and thunderstorms this afternoon. The
northwesterly winds are expected to increase slightly this
afternoon as the cold front passes. Conditions are expected to
improve overnight tonight across southern Wisconsin as high
pressure moves in from the west.

.MARINE...
(Issued 250 AM CDT Thu Apr 29 2021)

With the passage of a cold front late today, northwest winds will
pick up and may gust to 30 knots across the northern reaches of
the lake and approach or briefly meet small craft conditions in
the nearshore area. Otherwise high pressure will settle in for
Friday. A return to windier conditions looks likely Saturday into
Saturday night as a gusty southwest warm air advection regime takes
hold.
