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...

low pressure around 29.8 inches will remain over wisconsin and 
lake michigan through monday, leading to thunderstorm chances 
with severe storms possible this evening into tonight and again
monday afternoon. waterspouts and very strong winds are expected
with storms tonight, while winds and hail are the main hazards
expected monday. very warm, moist and unstable air flowing over 
the relatively cool waters may cause patchy dense fog over the 
lake through monday as well. 

northerly winds will develop monday night through wednesday as 
high pressure around 29.9 inches builds over the upper great lakes
and a cold front pushes southward. a few gale force gusts are 
possible tuesday afternoon. look for southerly winds and more 
unsettled weather to resume thursday into next weekend.
