Update
Very warm and humid conditions are expected today, and again
Saturday. Highs today should reach the lower to middle 90s inland,
with a lake breeze keeping highs cooler near lake michigan. Heat
index values will be in the middle to upper 90s. Thus, will not
issue a heat advisory for this afternoon.

Saturday's highs should be in the upper 80s to lower 90s, again
cooler near lake michigan with a lake breeze. Heat index values
Saturday should be in the lower 90s, with some middle 90s in
spots.

Warm and humid conditions should occur Sunday as well, with highs
in the upper 80s and heat index values around 90 degrees.

Southeast lake breeze is expected again in the afternoon.

Wood

Marine
Southeasterly lake breezes of 10 to 15 knots are expected into
this afternoon, and again late Saturday morning and afternoon.

Waves of 1 to 2 feet are generally expected, highest toward the
sheboygan area.

There may be some light fog during the overnight hours tonight
and Saturday night, especially toward sheboygan. At this time, no
dense fog is expected.

Prev discussion (issued 645 am cdt Fri sep 22 2017)
update...

still a little fog out there in the northeast forecast area this
morning, so will leave the dense fog advisory as is for now.

Conditions will improve over the next 1-2 hours.

Aviation(12z tafs)...

lingering fog this morning will diminish over the next 1-2 hours
as daytime heating kicks in.VFR conditions are then expected
for the rest of today into tonight under high pressure.

Prev discussion... (issued 337 am cdt Fri sep 22 2017)
short term...

today and tonight... Forecast confidence is high:
decided to put a dense fog advisory out for portions of the
northeast forecast area. Increasing low level winds should help
to improve things eventually. If the fog holds on into early
morning, daytime heating mixing will get rid of it quickly.

Plenty of sunshine is expected today with southern wisconsin
sitting under the western portion of high pressure. The very warm
airmass will remain in place today, with possibly the hottest
conditions of this warm spell. Went low 90s most places, but
wouldn't be surprised if temps creep toward 95 in a few spots
given 925 mb temps of 26c.

It will stay mild and dry tonight as high pressure builds more
into the area from the east.

Saturday and Sunday... Forecast confidence is high:
upper level ridging will remain in place through the weekend. A
surface high will remain centered over the great lakes, putting
southern wisconsin in light southerly flow all weekend. The
atmosphere looks rather dry at all levels, meaning mostly clear
skies. All this will result in temperatures remaining at near
record values across most of the cwa. That said, given the weak
flow, I do expect a lake breeze to develop both days. This will
keep lakeside communities from getting too close to record values.

Additionally, dewpoints in the mid to upper 60s may set us up for
at least patchy fog along lake michigan.

Long term...

Monday through Friday... Forecast confidence is medium:
guidance continues to show an upper trough moving into the region
early next week, finally kicking the ridge out of here. The gfs
remains a bit faster than any of the other guidance, beginning
precip on Monday morning in our west. However, any support for
precip looks quite weak until Tuesday afternoon or perhaps as late
as Wednesday morning. Regardless, confidence is high that we'll see
at least scattered showers and storms at some point early next week,
most likely Tuesday afternoon evening. Confidence regarding the
exact timing of the precip is a bit lower, but should increase as we
get through the weekend.

Aviation(09z tafs)...

fog in the northeast forecast area will diminish within a couple
hours of sunrise at the latest. Increasing southerly winds may get
rid of it sooner.

Vfr conditions are then expected today into tonight under high
pressure.

Marine...

dense fog mainly north of port washington is expected to improve
within a couple hours of sunrise this morning.

Winds and waves will remain on the low end today into the weekend
under high pressure.

Wi... None.

Lm... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
