open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
904 am cdt sat jul 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...

high pressure around 30.4 inches will remain well north of the
region today and tonight, shifting east to over james bay on 
sunday. weak low pressure around 29.9 inches will develop and 
slowly move east across northern illinois into indiana during this
time. scattered showers and some thunderstorms are expected at 
times through the weekend. fog, possibly dense at times, will be 
possible mainly over the northern portions of the lake, as warm 
and humid air flows over the relatively cooler lake waters. shower
and thunderstorm chances will end sunday night, with quieter 
weather for the start of next week.
