Short term
Tonight through Thursday... Forecast confidence is medium to
high...

as the upper level system across michigan continues to push east,
winds across southern wisconsin will begin to subside this evening
into the overnight hours. Some light breezes remain possible and
this coupled with lingering cloud cover will slow the temperature
trend this evening. The main question is just how much cloud cover
will hang around tonight. Models are showing slightly drier air
filtering in aloft and this should lead to a thinning of the
clouds tonight. However, think that enough moisture will exist to
keep some clouds in place. This will limit the amount of frost
possible tonight, which is why we've held off on issuing any frost
products for tonight.

We stay in the northerly flow for Thursday but expecting there to
be more sun, which will bring temps into the lower 50s for highs.

All in all it should be a nice Thursday across the area with
slight breezes and warmer temps.

Long term
Thursday night through Friday... Forecast confidence is high.

Light winds and early clear skies will allow temperatures to fall
into the upper 30s Thursday night. Depending on how quickly the
next round of clouds spread in, temperatures may drop into the mid
30s. Therefore, mentioned patchy frost in the forecast, mainly for
the east where they will be clear longer.

Look for increasing southerly winds and mild temperatures on
Friday as the next low pressure system approaches. Highs will be
in the mid to upper 60s with mid and high clouds streaming
overhead.

Friday night through Saturday night... Forecast confidence is
medium.

The low pressure trough will slide across southern wisconsin
during this period. Showers and a few thunderstorms should be
present along the leading edge as it moves across the area
Saturday morning. There is some uncertainty for timing at this
time, but no large differences. Models are coming into better
agreement each run. There should be a fairly steady progression of
the line of showers and storms from west to east, so not expecting
an all-day wash out. Nevertheless, a 2 to 3 hour period of rain is
likely.

Sunday through Tuesday... Forecast confidence is medium.

Expect increasing southeast winds ahead of our next system on
Sunday. Clouds will be increasing, but overall it will be a nice
fall day with highs in the lower 60s.

The next system will feature strong southerly winds out ahead of
it, along with scattered showers and isolated thunderstorms. The
low will be occluding over northern mn western wi Monday. Expect
gusty southwest winds in the wake of the front over southern wi
develop Monday night and then persist out of the west through
Tuesday night as the system sits near james bay. The ECMWF is
showing a slightly weaker pressure pattern than the GFS at this
time. The remains uncertainty about timing and wind speed with
this one.

Aviation(21z tafs)
Cigs continued to improve toVFR this afternoon but some brief
MVFR CIGS remain possible through the evening hours. There is some
uncertainty in whether or not CIGS off to the west of 2,600ft are
going to shift east tonight. Think drier air will work in helping
to keep skiesVFR overnight. Gusty N NW winds are expected to
continue this evening before starting to diminish tonight.

Marine
The near gale force winds in the near shore and gale force winds
in the open waters will gradually taper off late this afternoon
into the evening hours. The high waves across the central and
eastern portion of lake michigan will fall below 6 feet late
tonight into Thursday.

Winds switch to the south by Friday and an approaching system will
cause winds to increase back towards small craft conditions Friday
and Saturday. Winds could approach gale force early next week as a
strong system moves through the area.
