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...

north gales to 40 knots are expected across lake michigan through
the evening hours today. moderate to occasionally heavy freezing 
spray is also expected, particularly over the northern portion of 
the lake. 

by late tonight, high pressure around 30.3 inches will build into
the plains, and eventually cross the upper great lakes on 
thursday. low pressure around 29.4 inches will cross lake superior
on friday, and stall over the lower great lakes saturday while 
weakening to around 29.5 inches. colder air on the back side of 
the low will overspread lake michigan on gusty west winds on 
saturday and sunday. freezing spray will remain a concern given
the very cold temperatures.
