national weather service milwaukee/sullivan wi
901 pm cst tue jan 27 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...

modest to brisk west northwest winds will prevail over lake
michigan at least into thursday as weak low pressure remains over
the northern and lower great lakes with high pressure extending 
from the northern great plains into the lower missouri river 
valley. high pressure will strengthen into friday as weak low 
pressure progresses through the middle mississippi valley, 
turning winds briefly northerly to even northeasterly. winds shift
back to north-northwesterly and increase friday night. moderate 
to heavy freezing spray will likely develop once again as 
northwesterly winds continue through saturday.
