903 pm cst wed jan 28 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 around 30.0 
inches remains over the eastern great lakes and high pressure 
around 30.5 inches extends 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. during this time, a snow band will develop in 
central portions of the lake, with westerly winds to the west and 
northeasterly winds to the east. 

winds shift back to north- northwesterly and increase friday 
night as low pressure deepens in the atlantic. moderate to heavy 
freezing spray will likely develop once again. a second brief 
period of northeast winds is possible saturday morning as high 
pressure slides southward into the u.s. southeast and low pressure
in the atlantic deepens. winds become light and variable saturday
night into sunday as high pressure finally dominates the pattern.
