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 over northeast minnesota 
will result in southerly winds continuing this afternoon. 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.
