Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
628 PM CDT Sun Aug 2 2020

.UPDATE...

The upper level trough is swinging through the area at this hour,
with scattered showers and a few thunderstorms continuing across
the region. This activity will slowly diminish in coverage this
evening, though will likely linger in at least isolated fashion
across the eastern portion of the CWA into tonight. North winds
are starting to increase behind the surface cold front as well,
and will remain breezy through the overnight hours.

&&

.AVIATION(00Z TAFS)...

Scattered showers and a few thunderstorms continue across the area
early this evening. Ceilings have been variable thus far, with
MVFR associated with any shower/storm activity. Heading into this
evening, more widespread MVFR stratus will build in from the
north, behind the surface cold front. These lower ceilings will
persist overnight and at least through tomorrow morning. Some
clearing is possible by afternoon, though confidence in the timing
is low.

Winds are starting to pick up from the north now, and will remain
breezy overnight. Expect some gustiness to around 20 knots
through the day tomorrow, especially from late morning through
late afternoon.

&&

.PREV DISCUSSION... (Issued 415 PM CDT SUN AUG 2 2020)

SHORT TERM...

LATE THIS AFTERNOON THROUGH MONDAY - Confidence...Medium.

Scattered showers and thunderstorms will continue across southern WI
into the evening as sharpening short wave trof strengthens across
southern WI.  Also getting enhancement from right entrance region of
upper jet.  Lake breeze and nearby surface low pressure also adding
to the low level convergence.  Much cooler air will sweep across
southern WI tonight behind this low pressure system.  Blustery winds
will carry this much cooler air across the area.  The warm Lake
Michigan waters will result in steep low level lapse rates over the
lake. This will allow blustery north to northeast winds to cause
higher waves over the nearshore and shore areas later tonight and
Monday.  Wave heights are expected to get up to 5 to 8 feet on
Monday with a prolonged period of north to northeast winds.  Hence
wl be issuing a Lakeshore Flood Advisory for all lakeshore counties
for Monday and Monday night. Will also be issuing a Beach Hazard
Statement for all lakeshore counties as well due to the onshore
gusty winds causing high waves and a high swim risk from later
tonight into Tuesday.

The lingering mid-level trof across the western Great Lakes and cool
air continuing to flow down across the lake may bring more showers
to the area on Monday.  Also, can not rule out a thunderstorm by the
lakeshore due to lake induced CAPE of 500-1K joules.

MONDAY NIGHT THROUGH WEDNESDAY - Confidence...Medium.

Lake effect shower chances will continue into Monday night until low
level winds turn more to the north by Tuesday morning. Otherwise,
dry conditions expected over most inland areas for this period.
Lingering thermal trof and cyclonic curvature may result in
considerable cloud cover lingering across the area on Tuesday. Will
keep daytime temperatures somewhat in check due to the north winds
and possible cloud cover on Tuesday, with highs only around 70.  Wl
warm up daytime temps a bit on Wednesday as the low level flow
becomes more southwesterly as high pressure ridge sags to the south.

LONG TERM...

WEDNESDAY NIGHT THROUGH SUNDAY - Forecast Confidence...Low to
Medium.

Uncertainty grows during this period.  Latest extended guidance is
now showing a more vigorous short wave originating in southern
Canada moving southeast and flattening protective ridge across the
Upper Midwest Wednesday night and Thursday.  Moisture return will be
questionable for this feature, so may hang on to dry conditions on
Thursday for now.  Pacific northwest sharpening of long wave trof
will reamplify the ridge across the central CONUS into the Mountain
area of the west.  However all guidance is suggesting weak mid-level
short waves eclipsing the ridge and moving ESE from the northern
Plains into the western Great Lakes from Friday through Sunday.
Temperatures should return closer to normal and even above normal as
the low level flow becomes south to southwest once again.  For now,
may have small chance pops in for much of this period due to the
uncertainty regarding timing of synoptic lift and amount of moisture
return.

MARINE...

Cooler air flowing southward behind a cold front along with a
tightening pressure gradient will result in gusty north to northeast
winds over the near shore and open waters, developing tonight and
continuing into Tuesday.  The strongest winds are expected later
tonight into Monday, with gusts of 25 to 30 knots possible.  The
Small Craft Advisory remains in effect for the nearshore waters from
later tonight into Tuesday.  The cold air flowing across the much
warmer nearshore waters may generate a few waterspouts over the lake
on Monday and Tuesday.  The Convective Cloud Depth is not as deep
for a more widespread spout outbreak, however low level lake induced
CAPE and weak convergence areas associated with an inverted trof
would contribute to the potential for water spouts.

BEACHES...

Gusty north to northeast winds will develop tonight over the shore
areas of Lake Michigan behind a cold front and low pressure area.
Waves are expected to build to 4 to 7 feet with a few higher waves.
These conditions will cause dangerous swimming conditions at Lake
Michigan beaches from later tonight through Tuesday.  Hence a Beach
Hazard Statement has been issued for all lakeshore counties into
Tuesday.
