OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
239 AM CDT Wed Mar 13 2024

FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.

Waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.SYNOPSIS...

Light and variable winds this morning will become easterly to
northeasterly and increase steadily late today and tonight, as
low pressure of 29.5 inches moves from the Texas Panhandle into
northern Missouri. Breezy north to northeast winds are then
expected Thursday night into Friday as the low passes by just to
the south of Lake Michigan. Dense fog will also be possible during
this time, especially over the southern third of the lake.

Another area of low pressure of 29.4 inches will then pass by just
to the north of Lake Michigan on Saturday, bringing a round of
breezy southwest winds ahead of the associated cold front,
followed by northwest winds behind the front. Gusts to 30 knots
will be possible.
