open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
250 am cdt fri sep 4 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...

light and variable winds with periods of showers and thunderstorms
expected through this morning as a frontal boundary remains
stalled across the lake. some of these storms will be capable of
damaging wind gusts and hail, particularly over west-central
portions of the lake. potential for some scattered redeveloping
storms later today through tonight as the front remains stalled 
over the lake. 

high pressure around 30.1 inches builds into the great lakes
region from the north this weekend, leading to light northeast to
east winds and predominantly dry weather. shower and storm 
chances return to the forecast midweek next week.
