open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
829 pm cdt tue sep 15 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...
scattered showers and weak thunderstorms remain possible over
southern portions of the lake through wednesday as a frontal
boundary remains stalled south of the lake. a separate cold front
is set to cross the lake tonight, allowing the ongoing breezy
southwest winds to veer northwest and decelerate.
high pressure around 30.4 inches will track east across southern
ontario canada late tonight through wednesday, veering winds due
north then northeast. predominantly light and variable winds
expected late wednesday night through thursday as additional
high pressure forms over manitoba and weakens the pressure
gradient.
breezy east to northeast winds may then develop late this week
into this weekend as the aforementioned high pressure shifts
east across ontario canada and low pressure spreads east from
the great plains. the gradient between these two systems could
drive gusty winds from various directions depending on system
track, though our best guess is predominantly east (northeast to
southeast) for the time being.
