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...

southerly winds across lake michigan will gradually turn as low 
pressure around 29.2 inches lifts from the mo/ia border into the 
northern half of lake michigan overnight. will see gusty south to 
southeasterly winds over the southern half of lake michigan this 
evening as the low approaches then veering to southwest overnight.
lighter more easterly winds are expected for the north half of 
the lake, but gradually weaken as the low pushes northeastward 
into friday morning. behind the low, expect more north to 
northwesterly winds pick up into friday morning. given the tight 
pressure gradient on the backside of this departing system, will 
see gusts of 30 knots and a few brief gale force gusts through 
late friday morning, especially along the eastern lakeshore. 

winds will gradually weaken friday afternoon as high pressure 
around 30.2 inches works its way across the lake michigan through 
friday night. then looking at two areas of low pressure one coming
up from the southern plains and another digging down across the 
upper midwest merging over the great lakes for saturday. expect 
west- northwesterly winds over lake michigan to increase on the 
backside of this deepening low pressure as it lift into eastern 
ontario/quebec. will be a potential for gales across the open 
water, but still some uncertainty on the overall strength of the 
low pressure. then another high pressure will build across the 
region for sunday before another system traverses the region early
next week.
