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...

29.8 inch low pressure is positioned over the middle mississippi
valley this afternoon, resulting in breezy east winds across the 
southern half of lake michigan. winds are lighter further north, 
where higher surface pressure is in place. winds will gradually 
taper across all of the lake michigan late tonight through 
wednesday as 30.2 inch high pressure builds across the western 
great lakes. 29.6 inch low pressure will develop along the 
ontario-manitoba border wednesday night, deepening to near 29.5 
inches over the hudson bay by thursday afternoon. the low's 
development and progression will result in a southwest wind shift 
across lake michigan, with winds becoming gusty late thursday 
morning and afternoon. highest gusts are expected over the 
northern third of the waters, where 20-25 kt readings are 
currently forecast. gales aren't expected, though trends will 
continue to be monitored. a cold front will cross the waters 
thursday night, resulting in northwest winds friday into saturday 
morning. rain showers will continue into this afternoon over the

over the middle portion of the lake. additional rain is possible
