open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
258 am cst mon nov 9 2026
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 gradually become southwesterly and increase through
this evening as an additional area of low pressure around 29.7
inches progresses through the northern canadian prairies into
northern ontario. winds become northwesterly behind the
associated trough early tuesday morning, then diminish as high
pressure around 30.1 inches builds into the central plains and
mississippi river valley.
low pressure crossing illinois on wednesday will strengthen to
around 29.5 inches as it crosses indiana early thursday morning.
an additional strengthening of the pressure gradient is expected
over lake michigan on thursday. this will bring breezy north-
northeast winds wednesday night through thursday night. there is
increasing potential for gales on thursday, particularly over the
southern two thirds of the lake. wednesday night through friday
night, a strong north- to-south band of lake effect showers is
expected to develop. it will be predominantly rain, though some
snow could mix in at times. north winds remain gusty friday,
backing northwest and decelerating into saturday.
