open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
341 pm cdt thu mar 12 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...

very active conditions are anticipated across the open waters from 
tonight through the beginning of next week. currently in the 
northern great plains, 29.2 inch low pressure will approach and 
cross the northern half of lake michigan tonight through friday 
morning. southerly winds will quickly increase as the low 
approaches tonight, ultimately veering westerly to northwesterly 
as it moves into ontario friday evening. widespread gale force 
gusts remain forecast across the northern half of the open waters,
where a gale warning remains in effect between 10 pm cdt tonight 
and 10 pm cdt friday evening. even stronger gusts are expected 
across the southern half of the open waters, where confidence has 
increased in widespread storm force gusts in this forecast. a 
storm warning has thus been issued for southern lake michigan 
between 10 pm cdt tonight and 10 pm cdt friday evening. it's 
possible that winds could decrease below storm thresholds prior to
the current 10 pm cdt friday expiration of the storm warning. if 
necessary, any early cancellations will be handled as winds 
decrease friday evening. areas of rain and snow will accompany 
passing low pressure tonight. areas of light to occasionally 
moderate freezing spray are possible over northern lake michigan 
friday afternoon.

winds will taper away from headline thresholds later friday night 
through saturday as 30.2 inch high pressure builds into the 
northern great plains & ultimately crosses the open waters. east- 
northeast winds will steadily increase saturday night through 
sunday as a second area of 29.4 inch low pressure forms in the 
central great plains. the low will progress over or just south of 
the southern lake michigan sunday night as it deepens toward 29.1
inches, resulting in a northerly wind shift. winds will shift out
of the northwest monday as the low continues into ontario. expect
another prolonged period of gale, if not storm force gusts across
all of the open waters as the low approaches & shifts east of 
lake michigan early sunday morning through monday, with headlines 
becoming necessary within the next 12-24 hours. prolonged snow is 
expected saturday night through monday, some of which could be 
heavy. sleet or freezing rain could mix in with snow over southern
lake michigan saturday night into sunday. freezing spray 
potential will increase monday behind the departing low, with 
areas of moderate to heavy freezing spray possible. trends will be
monitored in coming forecasts for potential headlines.
