914 am cdt wed jun 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...

weak low pressure around 29.9 inches in northern minnesota this 
morning will result in southerly winds across the lake today. as 
this system pushes eastward through northern wi this evening we 
expect winds to decelerate, turning east over northern portions of
the lake and remaining south over the southern half. showers and 
thunderstorms are expected at times today and tonight with the 
passage of this system. 

light northwesterly winds are expected thursday as low pressure 
departs eastward. high pressure around 30.1 inches over ontario 
and the western great lakes will dominate friday through saturday 
with light north to northeast winds likely. sunday, low pressure 
deepens to 29.4 inches over the central plains, bringing breezy 
southeasterly winds to the lake. winds turn southerly and 
strengthen into monday as low pressure exits into the canadian 
prairies. on and off thunderstorms become more likely during this 
time.
