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... 

brisk south to southeasterly winds will weaken during the early
morning hours on tuesday with brisk northwesterly winds then 
developing from south to north across the lake for later tuesday 
morning. this is in response to low pressure around 29.7 inches 
moving from srn wi to northern lower mi into tuesday morning, then
deepening to 29.5 inches as it moves to southern quebec for
tuesday afternoon. meanwhile, arctic high pressure of 30.8 inches
will move from saskatchewan to the central united states by
friday. thus, modest to brisk west to northwest winds will 
continue for much of the week.
