Update
The forecast remains on track for this morning.

Aviation(12z tafs)
A shortwave will bring a chance for snow mid-morning into the
afternoon. The best chance for a light dusting will be north of
madison and milwaukee, though most places will see at least some
flurries. Ceilings will probably drop to MVFR for a times this
afternoon into early evening.

The combination of a weak wave and some possible lake
effect enhancement will likely bring some light snow to the
lakeshore counties mid evening into early tonight. This could
result in a quick dusting. MVFR ceilings and briefly lower
visibilities will be possible with this snow.

discussion...

today and tonight... Forecast confidence is medium to high:
a weak shortwave and surface low will move through the area today,
bringing a period of light snow. The best chance for a dusting
will be for areas north of milwaukee and madison. Most places are
expected to see at least some flurries though given some lift and
decent low and mid level saturation. This activity is expected
from around mid-morning through late afternoon. Below normal temps
will continue today, with highs struggling into the low 30s.

A weak low level trough will drop southward across the lake this
evening into tonight, bringing a wind shift to the north. Have
some chance to likely snow chances brushing the lakeshore counties
for a period of time. The mean low level flow will have a slight
easterly component, which should bring some lake enhancement effect
along with the wave. Could see a quick dusting.

Tuesday through Thursday... Forecast confidence is high.

High pressure over the area early on Tuesday will drift south in
response to low pressure tracking across lake superior. We'll see
a trailing front drift south into the area late Tuesday night, but
it'll wash out as high pressure quickly returns. So, continued
dry with any associated light snow staying well north. The cold
will continue on Tuesday with high temps running about 10 degrees
below normal. We modify a tad on Wednesday, but remain below
normal. A southerly flow returns on thanksgiving as high pressure
drifts east and low pressure takes shape over the central plains.

We remain dry with temps a notch warmer for the holiday... This
signals the start to a milder stretch of weather heading into the
weekend.

Friday and Saturday... Forecast confidence is medium.

We'll finally see some high temps in the 40s, but it comes with
the likelihood of some rainfall. A decent mid level short wave
will dig into the central CONUS on Friday and pivot into the great
lakes on Saturday. The various long range models are at odds with
the timing and form it will take, so there is some uncertainty
for precip timing. For now, the best chance looks like Friday
night into Saturday morning. It does look warm enough to keep the
bulk of the precipitation in the form of rain. The ec is much
slower than the GFS on Friday, holding off any rain until Friday
night. So, it's possible we could get a dry afternoon for all
those black Friday shoppers. We should see the rain diminish
Saturday afternoon.

Sunday and Monday... Forecast confidence is low.

How the pattern evolves into early next week is up for grabs. The
ecmwf generates a potent closed mid level wave Sunday night on
the heels of the one exiting on Saturday. The canadian has a
broader closed wave, while the GFS is more open and progressive.

The ec takes a deepening surface low across northeast illinois
with temps cold enough on the back side to bring snow to southern
wisconsin. But, the other models, given their weaker solutions
suggests little concern for snow. We'll have to wait and see on
this one.

Aviation(09z tafs)...

quiet weather is expected overnight, with high clouds lingering
across southern wisconsin. A shortwave will then bring a chance
for snow mid-morning into the afternoon. The best chance for a
light dusting will be north of madison and milwaukee, though most
places will see at least some flurries. Ceilings will probably
drop to MVFR for a times this afternoon into early evening.

The combination of a weak waves and some possible lake
effect enhancement will likely bring some light snow to the
lakeshore counties mid evening into early tonight. This could
result in a quick dusting. MVFR ceilings and briefly lower
visibilities will be possible with this snow.

Marine...

northerly winds gusting to 25 to 30 knots will develop by late
afternoon in the northern portions of lake michigan. This area of
higher gusts will travel southward through the lake during the
evening and overnight hours. Waves will increase as well. A small
craft advisory may be needed for the nearshore waters from late
evening into the night.

Lighter winds for the first part of Tuesday will pick up later in
the day and into the night. West to northwest gusts to 30 knots
seem likely. There will be a better chance for a small craft
advisory over the nearshore waters for this round of winds.

Gale force southerly winds may impact the area later Thursday
into Friday night.
