Update
Some lingering mist continues across parts of the CWA but should
push off to the east over the next few hours. Otherwise expect
breezy winds and mostly cloudy skies to continue through the day
today.

Aviation(12z tafs)
MVFR CIGS will likely last through this morning and into the
afternoon, however mixing could actually allow for a return toVFR
cigs by the late morning. Otherwise we will have continuing breezy
west northwest today, especially this morning, where some gusts
could reach 30-35 kts. Winds will begin to die down this evening
with the region expected to remain dry but clouds may stick around
through the overnight period into Thursday.

discussion...

today and tonight... Forecast confidence is high...

showers have mostly pushed over the lake as the surface low has
pushed to the north-central great lakes region. The very strong
pressure gradient on the backside of this low will remain
throughout the day allowing for very breezy winds throughout the
region. However, as we push into the evening the pressure gradient
will let up a bit allowing for winds to settle down. Higher
pressure will also be moving in, which will allow for clouds to
clear out a bit as well. This will bring some concerns for
temperatures to fall to near freezing leading to some frost
concerns.

Otherwise, the upper level low will continue east as well. Though
there will be some PVA on the back end of the upper level low
there will be a relative lack of moisture depth to produce
precipitation. A little upper level wave may pull through
overnight Wednesday into Thursday morning bringing continuing
cloud cover and maybe the possibility of an isolated shower but
there may not be quite enough mid level moisture to support
showers.

Thursday and Friday... Forecast confidence is high.

A nice couple of days here. A rather high amplitude mid level
ridge will be sliding across the area, pushing east by Friday.

Seasonably cool temps with a mix of clouds and Sun are expected on
Thursday. But, a return southerly flow sets up on Friday with
925mb temps warming to 7-10c by afternoon. This should push highs
in the upper 50s to mid 60s. The warmest readings will be found
west of madison. An onshore breeze will keep it cooler across the
southeast.

Saturday... Forecast confidence is high.

Strong low pressure will be tracking northeast across minnesota on
Friday with a trailing cold front reaching our western CWA border
late Friday night. Warm advection ahead of the front could bring
some showers into western areas after midnight. The front will
then drift through the area through early Saturday afternoon.

Expect scattered showers and possibly a thunderstorm as it moves
through. Since the parent low will be well up in canada by
Saturday, the trailing front will be gradually weakening washing
out as it reaches eastern wisconsin.

Saturday night and Sunday... Forecast confidence is high.

We should be able salvage a dry day out of this weekend. Weak high
pressure will slide through in the wake of the departing
trough cold front. Given that the front was mostly washing out as
it exited to the east, there won't be much cold air advection in
its wake, therefore, look for highs on Sunday still managing to
get into the lower and mid 60s.

Monday and Tuesday... Forecast confidence is medium.

The models are finally getting into better agreement in handling
the next storm system for early next week. A potent mid level
circulation will move through the central plains to northern
minnesota Sunday night through Monday. The associated strong
surface low will follow a similar track to the mid level system.

A strengthening low level jet by Sunday night should produce some
warm advection showers and possible thunderstorms across SRN wi,
though the h8 frontal boundary and better convergence should push
north of the forecast area quickly during the evening. The
associated cold front will likely push through the area primarily
during Monday morning, exiting out over lake michigan by early
afternoon. This should take the focus of heavier frontal boundary
rainfall east of the area during the afternoon. A few days ago,
the model solutions suggested a rather prolonged, multi-wave
scenario with copious rainfall across the upper midwest wisconsin.

Now, it is a rather consolidated system with the focus for
heavier rainfall located to our northwest, closer to the surface
low and to our east with developing afternoon convection along the
front. The caveat, of course, is if the the timing and track of
the low changes meaningfully, some of that heavier precip could
refocus over our area.

Drier and cooler air arrives for Tuesday.

Aviation(09z tafs)...

MVFR CIGS will continue this morning but will likely lift a bit by
the late morning thus restoringVFR conditions for the rest of the
day. Regardless winds will still be very strong from the
west northwest with gusts up to 30 kts through the afternoon
before weakening into the evening. Into the evening we also expect
clouds to clear out as higher pressure pushes into the region.

Marine...

a gale warning is in effect for the entire lake including the
nearshore areas as strong westerly northwesterly winds up to 45
kts will continue across most of the lake through the evening. The
gale warning for the nearshore only carries through this morning
but a small craft advisory will be needed once the gale warning is
expired as winds will still be quite breezy. The pressure
gradient will weaken into this evening as the low pressure system
pushes further east, which will allow winds to fall off into the
evening. Higher pressure will then allow winds to remain lighter
through at least Thursday.

Mkx watches warnings advisories
Wi... None.
