open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
237 pm cdt wed sep 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...

shower & embedded thunderstorm chances will continue along/ahead 
of a passing cold front over the southern third of lake michigan
through the rest of this afternoon. severe weather is not 
expected. high pressure near 30.1 inches will build in from the 
northern great plains tonight, lingering through thursday night & 
bringing light and variable winds to the waters.

a new area of low pressure near 29.2 inches will shift from
central canada toward the hudson bay friday morning through the
day saturday, bringing increasing south-southwest winds followed
by a west-northwest wind shift behind a cold front. occasional 
wind gusts near gale force are possible during this time frame, 
though whether or not they will be widespread enough to warrant 
headlines remains uncertain. trends will continue to be monitored
through the end of this week. periods of showers and storms will 
accompany the approaching/passing front, with widespread severe 
weather not currently anticipated.

high pressure near 30.1 inches will shift from the northern great
plains across lake michigan saturday night through sunday night,
bringing light and variable winds. the next area of low pressure 
& cold front will approach from the west early next week, bringing
increasing winds & additional chances for showers and storms. 
depending on the strength of the low and front, periods of gales &
some stronger storms could be possible. will be providing
additional details as this portion of the period draws closer.
