944 am cdt wed jun 10 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

.synopsis...

a warm front continues to lift northward over lake michigan this
morning, causing a wind shift to southeasterly. as the winds 
shift, fog continues to retreat northward over the lake. a marine 
dense fog advisory remains in effect at this time, with the
northern half's advisory running until 7pm cdt, while the middle
quarter will run until 2pm cdt. visibility has largely improved
over the southern end of lake michigan, and the advisory was
cancelled for this portion of the lake. winds will then remain 
southerly through today as low pressure of 29.3 inches approaches 
from the northern plains. the winds may become moderately breezy 
this afternoon into the evening. thunderstorms are expected over 
the lake at times on today, with some strong storms favored this 
afternoon into tonight.

winds come around to southwesterly tonight into thursday, with 
winds then returning to southeasterly ahead of an approaching cold
front on thursday, with additional storms possible.

winds will become westerly and breezy behind the front on friday 
as low pressure of 29.3 inches sits near hudson bay and high 
pressure around 30.0 inches builds into the mid mississippi river 
valley.
