open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
312 am 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 over the ohio river valley will advance 
into the northeastern united states today while a 30.4 inch high 
pressure builds into the canadian great plains. expect gusty 
northerly winds to exceed gale thresholds over lake michigan 
through early evening. while a few gale force gusts are possible 
in the northern third, the more persistent gales are expected for 
the southern two- thirds of the waters, where a gale warning 
remains in effect until 9 pm cst. northerly winds will remain 
steadily breezy and below gales tonight 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 and cold air over the warm waters will 
cause a band of lake effect precipitation to develop and persist 
through friday evening. this band will drift east and west at 
times toward the shorelines. 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.
