932 am cst Sat nov 17 2018

Update
The snow is tapering off over southeast wisconsin this morning.

There are no weather concerns upstream, so expect quiet weather
with mostly cloudy skies for the rest of the day. We will see more
breaks in the clouds during the afternoon. Temperatures will hover
around the freezing mark for the rest of the day and drop into the
teens overnight.

Marine
North to northwest winds will gust to around 20 knots today,
particularly across the north half of the lake. Westerly gusts to
25 knots are expected in the north on Sunday. This will build
some higher waves across northeast portions of lake michigan.

Gusty conditions will be possible again Monday night and Tuesday
night, though winds are expected to remain below gale force. Winds
across the nearshore areas could approach small craft advisory
conditions during this period.

update...

the back edge of the snow is entering the northwest forecast area
early this morning. The snow is expected to gradually come to an
end northwest to southeast through mid-morning.

Aviation(12z tafs)...

snow will continue this morning with visibilities in the 1-3 mile
range. The snow will wind down from northwest to southeast during
the early and mid morning hours.

Ceilings are mainly MVFR this morning and will likely hang on
through the morning and possibly into the afternoon... Especially
toward the il border. A return toVFR is expected by this evening,
as mainly mid and high clouds linger in the area.

discussion...

today and tonight... Forecast confidence is high:
snow will wind down northwest to southeast during the early and
mid morning hours today, exiting the southeast forecast area by
noon. Storm totals of 2 to 3 inches are expected in the southwest
forecast area, with lesser amounts toward the northeast. Though
totals are a little less than in the previous forecast, there
should still be enough snow to warrant keeping the winter weather
advisory.

Unfortunately, it looks like clouds will hang around most, if not
all of the day. Temperatures will struggle to get above freezing
today given the clouds, fresh snow, and a below normal airmass.

There will be at least lingering high clouds tonight, which will
limit radiational cooling. It does look like north northwest areas
could clear later in the night, so have lowest temps there.

Sunday... Forecast confidence is high.

High pressure will keep it quiet on Sunday, though it will begin
to drift south in response to low pressure approaching from the
northwest. It will remain cold with highs running a solid 10
degrees below normal.

Monday... Forecast confidence is high.

The low pressure system and it's associated cold front will track
across wisconsin on Monday. Overall, this is a rather weak system
with limited moisture. But, it may generate some light snow with
the trough frontal passage, mainly Monday afternoon and especially
north of milwaukee and madison.

Tuesday through Thursday... Forecast confidence is high.

We should be rather quiet through the middle of next week. Low
pressure does track north of the great lakes on Tuesday. We'll
have to keep an eye on the trailing trough front for some light
precip that may sneak farther south. But, it looks like it will
stay too far to the north to be of concern. Additionally, high
pressure to the south will effectively cut off any moisture, so it
looks dry during this period. Temps will modify a bit, but still
remain below normal.

Friday and Saturday... Forecast confidence is medium.

High pressure becomes anchored over the east coast with a decent
trough approaching from the west. The resultant southerly flow
will finally allow a milder and more moist airmass to return to
the upper midwest late in the week. Both the GFS and the ecmwf
bring in some rain for Friday into Saturday. We should see temps
climb into the 40s.

Aviation(09z tafs)...

snow will continue this morning... With visibilities dropping to
the 1-3 mile range. The snow will wind down from northwest to
southeast during the early and mid morning hours.

Ceilings continue to come down this morning and MVFR ceilings
will likely hang on through the morning and possibly into the
afternoon. A return toVFR is expected this evening into tonight,
as mainly high clouds linger in the area.

north to northwest winds will gust to around 20 knots today,

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.
