open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
857 pm cst wed nov 11 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...

29.8 inch low pressure will move quickly from the mississippi 
river into the ohio river valley tonight, advancing into the 
northeastern united states thursday. north winds will increase as
the low moves east, with gusts expected to approach and eventually 
exceeded gale thresholds thursday morning & afternoon. meanwhile a
30.4 inch high pressure builds into the canadian great plains. 
best potential for gales will be over the southern two-thirds of 
the waters, where a gale warning remains in effect between 3 am 
and 9 pm cst thursday. northerly winds will remain steadily 
breezy and below gales thursday night through friday as the high 
moves east toward hudson bay. winds will taper sunday into monday
as a 30.2 inch high pressure builds directly over the open 
waters.

persistent north winds will allow cause a band of lake effect
precipitation to develop late tonight and last through friday
evening. this bad will develop over the central portions of the 
lake and drift east or west at times toward the shore. rain will 
be the predominate precip type, but can't rule out some snow 
mixing in over the northern half of the lake. there will also be a
potential for a few thunderstorms with waterspouts. will be 
monitoring for any possible special marine warnings or marine 
weather statements.
