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...

fog with visibilities between 1/2 and 1 mile will continue through
the morning hours across the southern third of lake michigan,
while patchy freezing drizzle continues across the northern half. a
marine dense fog advisory is in effect through 10 am cst for the
southern third. 

low pressure around 29.5 inches over eastern kansas this morning 
will lift northeastward into southern lake michigan by this 
evening. southeasterly winds will back to easterly this morning, 
then will rapidly shift to northwesterly as the low crosses the 
lake tonight. isolated thunderstorms are possible across the
southern third of the lake this afternoon.

low pressure will deepen quickly to 28.7 inches as it lifts into 
southeastern ontario into monday morning. northwesterly storm 
force gusts of 50 to 55 kt are therefore expected sunday night 
through monday night, with the strongest gusts during the early 
morning hours monday through monday afternoon. low pressure will 
slowly exit into the canadian maritimes into tuesday morning, 
leading to slowly diminishing winds through the day tuesday. a 
storm warning is in effect for all of the open waters of lake 
michigan from 7 pm cst this evening to 6 am cst tuesday. moderate 
freezing spray is also expected during the timeframe of storm 
force winds. breezy northwest winds will then linger through the
