212 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 on thursday. progression of the low 
will result in steady increases in northerly winds this evening 
through thursday, with gusts eventually approaching or exceeding 
gale thresholds thursday morning & afternoon as 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---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 the development of a band 
of lake effect precipitation late tonight through friday. expecting 
the band to initially develop over west-central portions of the 
lake, with a gradual eastward drift thursday afternoon into friday.
low level temperatures will be supportive for mainly rain, though 
some snow could mix in over the northern half of the lake. forecast 
confidence in a few thunderstorms with waterspouts has increased 
through the overnight hours, with mentions now included in the 
forecast. will be monitoring for any possible special marine 
warnings or marine weather statements. anticipating that the lake 
effect band will dissipate by friday evening.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
212 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 on thursday. progression of the low 
will result in steady increases in northerly winds this evening 
through thursday, with gusts eventually approaching or exceeding 
gale thresholds thursday morning & afternoon as 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---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 the development of a band 
of lake effect precipitation late tonight through friday. expecting 
the band to initially develop over west-central portions of the 
lake, with a gradual eastward drift thursday afternoon into friday.
low level temperatures will be supportive for mainly rain, though 
some snow could mix in over the northern half of the lake. forecast 
confidence in a few thunderstorms with waterspouts has increased 
through the overnight hours, with mentions now included in the 
forecast. will be monitoring for any possible special marine 
warnings or marine weather statements. anticipating that the lake 
effect band will dissipate by friday evening.
