open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
248 pm cdt sat may 23 2026

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...
low pressure of 29.9 inches currently entering the western portion
of lake erie has left a weak wind field in its wake as it tracks
to the east toward new england. another area of low pressure of
29.8 inches currently over far southeast manitoba will track
eastward across ontario tonight into sunday and pull a weak cold
front eastward along with it. this front should reach eastern lake
michigan early sunday morning and exit by late morning. going into
early next week, a broad ridge of high pressure of 30.2 inches is
expected to set up over the eastern great lakes, ushering in more
southwesterly winds across lake michigan. some questions remain
for later in the week with whether a cold front drops down from
the north by midweek.
