Discussion
Tonight and Thursday... Forecast confidence is medium to high.

Gusty south winds will diminish rapidly early this evening. Fog
will continue to tickle the lakeshore as warm, moist air continues
to flow across the shore areas. The fog should thin and get pushed
out over the lake later tonight when winds turn to the southwest.

Moderate instability along with strong low level and bulk shear
ahead of an approaching weak low pressure trof convergence wl get
some lift enhancement from the right entrance region of an upper
jet. Mid-layer q-vector convergence does increase to 10-20 units
this evening indicating the enhanced synoptic lift. These
features are expected to trigger scattered convection across the
central and east from late this afternoon through the evening. Can
not rule out a few strong to severe storms due to the strong
shear and CAPE up to 1000 j kg. Enhanced lift moves off to the
east later tonight ending the convection threat. Warm front should
be mostly north of the area, but may arc down into the sheboygan
county area into the evening. In addition, NAM is showing a period
of low level frontogenetical forcing as weak convergence moves
through this evening.

Sharp short-wave ridging at the mid-levels and an influx of drier
air will result in a pleasant but breezy day on Thursday. Lot of
sunshine and seasonal temps.

Thursday night through Saturday night - confidence... Medium
an unsettled period is expected. Later Thursday night we should
start to see the influence of low level warm air advection take
hold. This will be ahead of low pressure in the northern plains.

The lingering influence of high pressure may end up keeping parts
of the east dry. Mid level flow will also turn more west southwest
as ridge axis shifts east. This will help lead to greater rain
chances during the day Friday and into Friday evening. This will
also be when low level warm moist advection will be heightened. A
trailing cool front may not move as fast as the ECMWF is implying
given the steering flow. The front could hang around with waves
of energy riding along the boundary keeping shra tsra chances
going well into Saturday evening.

Sunday and Sunday night - confidence... Medium
some consensus that a break in the rain would occur this period.

Low level anticyclonic flow takes hold and the boundary may end up
shifting far enough south to allow the focus to take rain with
it. The 12z GFS suggests the break will not be for long though as
a return low level warm air advection resumes Sunday night
bringing precip back to the area. Meanwhile the 00z ECMWF keeps
things dry Sunday night.

Monday through Wednesday - confidence... Low to medium
looks like a continued unsettled period with potential for a few
rounds of showers storms as meandering frontal boundary meanders
the upper midwest. The mid upper level flow will be largely
southwest which favors pockets of energy riding northeast within
this flow. Main trough could eject northeast towards the end of
the period. Will use blended temps pops.

Aviation(21z tafs) As low level winds continue to veer to the
south, expect the remaining areas of low clouds and fog closer to
lake michigan to thin and dissipate. Other patchy MVFR ceilings
should lift toVFR this afternoon. Still expect scattered showers
and storms to develop late afternoon and evening and affect eastern
areas with lower visibilities.VFR conditions return later tonight
and Thursday.

Marine Dense fog will continue to be a threat over the nearshore
and open waters tonight until winds turn to the west to southwest
and drier air spreads across lake michigan later tonight into Thursday
morning. A dense fog advisory remains in effect north of north point
light, but the fog is beginning to thin from north point light to
port washington. May be able to cancel this part of the advisory
late this afternoon, but more fog may develop this evening. Gusty
southeast to south winds will diminish during the early evening
with subsiding wave heights. Hence wl continue small craft advisory
for the nearshore waters until 7 pm. Gusty west winds are expected
on Thursday and will have gusts of 20 to 22 knots at times, getting
close to small craft advisory levels.

Beaches Gusty south to southeast winds will continue through
the late afternoon, with gusts at the shore up to 25 to 30 mph.

These gusty winds will keep waves elevated, so high swim risk threat
will continue and beach hazards will remain in effect until 7 pm.
