open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
201 pm cst thu nov 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...

29.5 inch low pressure will advance into the northeastern united 
states this evening. progression of the low will support 
continued increases in northerly winds, with gusts exceeding gale 
force through this evening as 30.4 inch high pressure builds into 
the canadian great plains. a gale warning remains in effect until 
9 pm cst this evening over the southern two-thirds of the waters. 
northerly winds will remain steadily breezy---though below gale 
thresholds---through the day on friday as the aforementioned high
nudges east toward the hudson bay. winds will taper sunday into 
monday as 30.2 inch high pressure builds directly over the open 
waters.

persistent northerly winds will allow for continued lake effect 
precipitation through friday. expecting precip to gradually drift 
eastward tonight into friday. low level temperatures will be 
supportive for mainly rain, though some snow could mix in over the 
northern half of the lake. a few thunderstorms are possible, 
particularly over the southern half of the waters. can't rule out a 
waterspout in any deeper thunderstorms that manage to develop. will 
be monitoring for any possible special marine warnings or marine 
weather statements. anticipating that lake effect precip will 
dissipate by friday evening.
