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 29.4 inches over the central great plains
today will track northeast and strengthen to around 29.3 inches 
as it crosses lake michigan by tonight. gusty south to 
southeasterly winds will occur over the southern half of lake 
michigan this evening as the low approaches, veering southwest 
late. lighter east winds are expected for the north half of the 
lake. as the low departs to the northeast early friday morning, 
it swings a cold front southward across the lake. gusty north to 
northwest winds are expected behind it, which will persist through
early friday afternoon. both of these periods of gusty winds are 
expected to prevail below gale force but we cannot rule out a few 
brief gale force gusts. then weak high pressure crosses the lake

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 29.4 inches over the central great plains
today will track northeast and strengthen to around 29.3 inches 
as it crosses lake michigan by tonight. gusty south to 
southeasterly winds will occur over the southern half of lake 
michigan this evening as the low approaches, veering southwest 
late. lighter east winds are expected for the north half of the 
lake. as the low departs to the northeast early friday morning, 
it swings a cold front southward across the lake. gusty north to 
northwest winds are expected behind it, which will persist through
early friday afternoon. both of these periods of gusty winds are 
expected to prevail below gale force but we cannot rule out a few 
brief gale force gusts. then weak high pressure crosses the lake
