open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
905 am cst tue dec 16 2025

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...

high pressure around 30.4 inches lingers over the southeast u.s.
through wednesday as low pressure around 29.0 inches lifts from
central manitoba into quebec tonight. this will lead to
southwesterly gales of 35 to 40 kt across the northern two-thirds
of the open waters this afternoon through early wednesday morning.
a gale warning is in effect. winds veer northwest late tonight as
a cold front extending south of the low crosses the lake, 
diminishing behind the front.

another strong low pressure system around 28.9 inches is expected
to track eastward along the canadian border wednesday into 
thursday. winds will turn south and remain light in the middle of 
the day wednesday, rapidly accelerating wednesday evening. 

strong south winds will develop ahead of the low wednesday night
(gales likely for most of the lake, strongest further north). a
cold front crosses the lake mid day thursday, with winds veering
northwest behind it. gales are likely behind this front as well,
and may last into friday morning before dissipating. 

a lull in the winds occurs friday afternoon, before a weaker
low pressure system follows in the tracks of the prior system. 
southerly gales are possible friday night.
