open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
314 pm cdt tue apr 14 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...

a stationary front will remain parked over the middle third of
the lake into tomorrow, slowly sinking south to the southern end
of the lake by thursday morning. winds will remain southerly
south of the front and modestly breezy, while winds north of the
front will remain light and variable to northerly during this
time. today, severe storms are expected over the southern half
to southern two thirds of the lake. hail and gusty winds will be
possible and waterspouts may occur with any tornadic storms from
land that move over the waters. this will be most likely near
the shoreline of wisconsin and illinois. 

the front will clear the lake as a cold front friday, before 
low pressure of 29.6 inches approaches from the west.
