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 late 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
gale force gusts.

weak high pressure crosses the lake friday night, with light and 
variable winds shifting east. another low pressure system tracking
northeast from arkansas/louisiana will pass south of lake 
michigan on saturday. the west to northwest winds behind this 
system for saturday night into sunday may reach gale force over 
lake michigan.
