open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
901 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 northeast into the new
england states this evening. meanwhile a 30.4 inch high pressure
is building into the canadian great plains. 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. 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.
