Update
No adjustments to the going forecast with broad ridging over the
region. Main focus is on cloud cover as the fair weather cumulus
near lake michigan has become a bit more widespread than indicated
in the short term guidance, likely due to some extra moisture
coming off of lake michigan. Cloud cover will quickly dissipate
going into the evening hours on into Saturday as the ridge of high
pressure drifts southeast across the great lakes.

Aviation(18z tafs)
Vfr conditions are expected through Saturday as a ridge of high
pressure moves across the great lakes region. A CU field has
developed across southern wisconsin with and has generally been in
the 3kft to 5kft range and a little more widespread closer to lake
michigan. Expect that this CU field will dissipate going into the
evening hours. Could see some valley fog in the wisconsin river
basin overnight, but the air overhead looked pretty dry. Winds
will generally go from the ene to the ese into tomorrow as the
ridge moves through.

update...

temperatures starting a couple of degrees below where we were
yesterday at this time (lower 60s). The mid-level clouds out there
now will clear by later this afternoon and highs warm into the low
to mid 70s. One interesting feature is over the lake where
convergence in the wind field is evident in the cloud structure.

Visible imagery would suggest some slightly deeper development
along the convergence axis. While a few returns were showing up on
radar, there is enough dry air present that only a stray sprinkle
or virga are expected.

Marine...

high pressure to the north will keep winds out of the N ne. Some
stronger winds are possible over the lake with gusts to 20 knots
possible at times. This will allow for some building of waves
across the far southern portions of the lake where waves could
increase to 3 to 5 feet. Winds and waves begin to relax tonight
into Saturday.

Prev discussion... (issued 639 am cdt Fri aug 23 2019)
update...

clouds continue to linger this morning and have updated sky cover
to reflect this. Otherwise, the forecast looks on track for the
upcoming day.

Aviation(12z tafs)...

other than some patchy fog given enough clearing tonight,VFR
conditions are expected to continue over the next 24 hours. Clouds
in the 5-8 kft range continue to linger and may persist into the
day today. Even if these wipe this morning, late morning and
afternoon cumulus clouds are expected, mainly away from lake
michigan.

Prev discussion... (issued 238 am cdt Fri aug 23 2019)
short term...

today through Saturday... Forecast confidence is high:
high pressure will bring continued quiet weather to southern
wisconsin through Saturday. Stubborn 5-7 kft clouds continue to
hang around and may persist into the day today. If anything, there
should be enough moisture for decent afternoon cumulus coverage
today and again Saturday. There will be less clouds toward lake
michigan under onshore flow.

Temps through Saturday should be within a couple degrees of what
was observed over the last day. Highs will remain a tad below
normal for late august.

Given light winds at night under the high and enough clearing,
there could be some fog in the typical susceptible locations,
though primarily within the wisconsin river valley.

Long term...

Sunday through Monday night... Forecast confidence high...

dry weather will continue through at least the daytime hours on
Sunday, as high pressure pushes into northern new england.

Temperatures should be in the mid to perhaps upper 70s.

Rain thunderstorm chances start to increase late Sunday night, and
especially into Monday, as two shortwaves approach from the west
and southwest. There continues to be some significant differences
within the guidance as to if and where the two waves phase, with
the GFS favoring a slightly earlier onset to precipitation.

Monday and Monday night should be most active for shower and
thunderstorm activity, before a cold front moves through the
region early Tuesday.

Tuesday through next Friday... Forecast confidence moderate to
high...

fairly breezy west winds are expected for Tuesday and Wednesday,
with the region situated between strong low pressure across
northern ontario, and a large surface high over the southern
plains. We'll likely be on the southern periphery of the shower
activity associated with the upper low, so low pops seem
reasonable for this time period.

Another front is expected to swing through the area late in the
workweek, with canadian high pressure building south as we head
into labor day weekend. This should set the stage for temperatures
a few degrees below average as we finish out the month of august.

Aviation(09z tafs)...

other than some patchy fog given enough clearing later tonight,
vfr conditions are expected to continue over the next 24 hours.

Clouds in the 5-7 kft range continue to linger and may persist
into the day today. Even if these wipe this morning, late morning
and afternoon cumulus clouds are expected, mainly away from lake
michigan.

Marine...

high pressure centered just north of lake superior early this
morning will slowly slide eastward into the weekend, reaching
maine by Sunday morning. North to northeast winds today will
become easterly Saturday, with a southeast component by Sunday as
the high moves on. Winds will be breezy at times through Sunday.

Southeast winds will pick up Monday between an approaching low and
the departing high. Winds and waves may reach small craft advisory
levels.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
