open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
304 am cdt thu apr 18 2024

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...

another low pressure area of 29.6 inches will deepen across 
ontario today into northwest quebec for late tonight into friday.
with a strengthening high pressure of 30.7 inches in western
canada impinging southeastward the pressure gradient will sharply
increase for friday across the region leading to breezy westerly 
winds across the lake during this time. however, winds are not
expected to be as strong as over land due to the cooler waters of
the lake. through the weekend the high pressure will weaken as it
slides southeast meaning winds will trend lighter while remaining
largely from the west to northwest.
