Update
The short term forecast is quiet into Monday and is on track.

We're still expecting an area of low clouds to push into southern
wisconsin from illinois later Monday afternoon, followed by some
small rain chances Monday night.

Aviation(06z tafs)
Look for an area of MVFR clouds to begin pushing into southeast
wisconsin toward mid to late afternoon on Monday. These clouds
will eventually overspread all of southern wisconsin through
Monday evening, likely dropping to ifr levels in some locations.

Until then, look forVFR conditions under clear to scattered sky
cover. Winds will be steady out of the southeast through the
period.

update...

the forecast is behaving itself. No changes needed.

Marine...

high pressure of 30.5 inches will continue to drift across
ontario and quebec, canada into Monday. Winds will increase out of
the east southeast overnight across all of lake michigan,
remaining elevated through Monday morning, before diminishing
Monday afternoon as the high slips farther away. Expect building
waves tonight, especially over the northern and western portions
of lake michigan.

The nearshore waters will see increasing winds and waves later
tonight through Monday morning as east to southeast winds
increase. Have decided to post a small craft advisory north of
port washington from 4 am through noon on Monday due to the
somewhat elevated conditions.

Beach...

decided to put out a beach hazards statement for sheboygan county
due to the expected increasing southeast winds and building waves.

It's a small window that will run from 4 am through noon on
Monday.

Prev discussion... (issued 548 pm cdt Sun sep 23 2018)
update...

the short term forecast is on track. We'll see more wind above any
shallow inversion that develops tonight, so that should help keep
temps from dropping under these clear skies. Still looking at
increasing clouds on Monday.

Aviation(00z tafs)...

look forVFR conditions through most of the TAF period. Moisture
will be surging north on Monday, with MVFR CIGS pushing into the
kenw toward 21z Monday and a few hours later at kmke kues. Those
lower CIGS will reach kmsn Monday evening. Expect a persistent
east to southeast wind during the TAF period.

Prev discussion... (issued 250 pm cdt Sun sep 23 2018)
discussion...

tonight and Monday - confidence... Medium
lingering influence of high pressure will dominate for much of
this period. As the southeast trajectories become more established
on Monday it taps into some of the stratus from the mid miss vly
and oh vly and expands it northward towards the western lakes. So
an uptick in cloud cover is expected on Monday. The models are
trending drier QPF wise so think the chance for any precip looks
pretty low in the south and east. MOS temps in the upper 60s low
70s look reasonable.

Monday night through Tuesday night - confidence... Medium
broad mid level trough will be approaching and arriving later in
period. In addition a surface 850 front will be approaching and
passing Tuesday night. So there will be an axis of moisture ahead
of the front so expecting best rain chances Tuesday afternoon and
evening as the front moves through. Some CAPE noted in bufkit
soundings so will retain mention of thunder.

Wednesday - confidence... Medium
cold advection briefly takes hold in the wake of the departed
front. The flow turns more westerly later in the day into
Wednesday night as the flow starts to react to another quick
hitting system upstream.

Thursday - confidence... Medium
another cold front will sweep through in the afternoon evening
hours with more shower potential.

Friday through Sunday - confidence... Low
looks like the pattern will become increasingly more unsettled as
a couple more systems affect the region.

Aviation(21z tafs)... CU field in far SE wi that moved in off the
lake has dissipated. Influence of departing high pressure will
continue into at least Monday morning with plenty of skc. Some
moisture increase may result in the advection of some lower
ceilings Monday afternoon and evening.

Marine... Lingering influence of high pressure keeping winds on
the lighter side, however front dropping into the far northern
reaches of the lake will allow east winds to pick up later today
and into tonight. Southeast winds will increase a bit on Monday
ahead of low pressure.

Mkx watches warnings advisories
Wi... Beach hazards statement from 4 am cdt Monday through Monday
morning for wiz052.

Lm... Small craft advisory from 4 am to noon cdt Monday for lmz643.

Update... Davis
