open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
859 pm cdt sun may 24 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...

high pressure around 30.2 inches developing southeast of the lake
overnight will bring south winds. as the high develops, dense fog
will continue to spread across the lake. a dense fog advisory is 
in effect into middle morning on memorial day.

the high pressure system will push to the east on memorial day,
but will keep precipitation mostly away from the lake. there may 
be small chances for showers or a storm over the northern part of
the lake later in the day into monday night, with a warm front in
the vicinity. 

some chances for showers and storms are forecast later tuesday 
into wednesday, as the front sags back south as a cold front. high
pressure around 30.3 inches is expected to build toward eastern 
hudson bay tuesday into wednesday, which may help push the cold 
front southward across the region.
