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...

winds will become southerly today and breezy tonight as the low 
pressure system around 29.7 inches pushes into the western great 
lakes region. there may be a few isolated gales in the southern 
half of the lake tonight. this low will cross the lake wednesday 
morning, and northwest winds will become gusty wednesday 
afternoon and evening behind the exiting low. a brief period of
gales is possible midday wednesday and we are still assessing the
need for a gale warning. northwest winds decelerate wednesday 
night as high pressure passes just south of the lake.

as high pressure tracks east and a more robust low pressure
around 29.4 inches approaches from the dakotas through the upper
peninsula of michigan, breezy south winds develop on thursday, 
peaking thursday night with gales possible for a period. the 
passage of the cold front may then lead to gusty northwest 
winds friday with gales possible here as well.
