open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
913 pm cdt thu sep 3 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...

no major changes to the synopsis this evening as the overall
pattern and forecast remains largely unchanged. some marine dense
fog may form tonight, mainly over the middle third of the lake,
close to a stalled frontal boundary.

otherwise, the frontal boundary will remain across the great 
lakes region through friday. as this frontal boundary waffles 
north to south across the lake from day to day, generally east to 
northeast winds are expected north of the front, with east to 
southeast winds south of the front. on and off thunderstorms will 
be possible along and north of this frontal boundary through at 
least friday night. then high pressure around 30.1 inches builds 
over hudson bay on saturday, while low pressure around 29.6 inches
moves into the northern great plains. similar to earlier week 
storms, widespread severe weather is not anticipated, though 
isolated stronger storms with hail and gusty winds are possible.
