short term...

tonight and Wednesday... Forecast confidence is high.

Cyclonic flow prevails tonight as a closed upper circulation
traverses the upper great lakes. Skies will clear this evening,
with good radiational cooling allowing temperatures to drop into
the 50s (perhaps even a few upper 40s in spots).

We'll remain in northwest flow tomorrow with a shortwave trough
dropping through the western upper great lakes. Cooler air will
ooze down from the north, with 925 mb temperatures falling into
the 10 to 12 degree range by Wednesday afternoon. Some cloud cover
is possible (especially in the east) in association with the
approaching upper wave. Otherwise look for cooler temperatures
with highs in the lower to mid 70s.

Wednesday night and Thursday... Forecast confidence is high.

A shortwave will push southeast into wisconsin on the west side
of the upper trough late Wednesday night, as a jet MAX pushes
southeast. Upper level divergence moves across southern wisconsin
late Wednesday night, along with 700 mb upward motion, but it
weakens as it reaches the forecast area. Mid levels saturate, but
this occurs above 700 mb. As such light rain may evaporate with
mainly virga. A weak surface trough will drop south across the
large surface high across the upper and mid mississippi valley.

Long term...

Thursday night through Saturday... Forecast confidence is high.

The upper trough slowly reaches the northeast u.S. Thursday
night. The upper flow over wisconsin then becomes more zonal
Friday. A weak shortwave moves into the upper mississippi valley
Saturday.

High pressure and cooler air remains into Friday. The high is
expected to be over the eastern great lakes Saturday, with weak
warm advection on the back side of the high. The GFS brings light
showers into a few west areas Friday night and Saturday, but the
ecmwf is dry.

Sunday through Tuesday... Forecast confidence is high.

The upper shortwave drops into wisconsin Sunday, but is fairly
weak. The shortwave remains through Tuesday on the ecmwf.

The ECMWF is a bit more aggressive in bringing some showers into
the east, with the GFS slower to push the ridge over the great
lakes off to the east.

Aviation(18z tafs)...

sct-bkn 040-060 cumulus will dissipate around sunset. Skc
thereafter. Gusty NW winds up to 25 knots will decrease this
evening.VFR conditions will continue into tomorrow.

Marine...

offshore winds will remain close to small craft advisory levels
through early evening, with gusts occasionally reaching 25 knots.

The higher waves should be confined near the open waters given the
offshore flow. Small craft should exercise caution into early
evening. The gusty northwest winds will veer northerly and weaken
late tonight into Wednesday morning.

Mkx watches warnings advisories
Wi... None.

Lm... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
