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...

winds have fallen below gales, but gusty northwesterly winds and
moderate freezing spray concerns continue this morning as lake
michigan sits between strong low pressure around 28.9 inches
meandering over quebec and a high pressure around 30.6 inches 
moving south across the plains. will then see the gusty winds 
shift more westerly this afternoon as an area of weak low pressure
around 29.9 inches and cold front slides down across the region. 
northwesterly winds return overnight behind the frontal passage 
with a few gale force gusts possible across the far northern 
portions of the lake. will see another cold front move down across
the lake wednesday with northwesterly winds prevailing through 
the end of the week. behind the front, colder arctic air will 
settle over the region as high pressure around 30.3 inches builds 
down across the upper great lakes region wednesday night into 
thursday. could see additional freezing spray concern through the 
end of the week given breezy winds and the colder airmass.
