open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
851 pm cst sun feb 5 2023

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...

northerly winds will continue to weaken as high pressure around 
30.2 inches moves over southern lake michigan tonight. the high 
will exit to the east and winds will begin to pick up and shift to
the southeast through the day monday ahead of an approaching 
system. strong southerly winds with gale force gusts are expected 
by monday night and will persist into tuesday morning. then as 
the center of low pressure deepens to around 29.1 inches while it
tracks into the hudson bay region well north of lake michigan, it
will drag a cold front across the lake through tuesday morning. 
as the front quickly exits the region, winds will gradually weaken
through the day tuesday as they briefly shift to the west while 
another area of high pressure skirts just south of lake michigan 
tuesday night. then expect another low pressure to lift into the 
region from the southern plains for the middle of the week 
bringing another round of gusty winds over the open waters 
through the end of the week.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
851 pm cst sun feb 5 2023

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...

northerly winds will continue to weaken as high pressure around 
30.2 inches moves over southern lake michigan tonight. the high 
will exit to the east and winds will begin to pick up and shift to
the southeast through the day monday ahead of an approaching 
system. strong southerly winds with gale force gusts are expected 
by monday night and will persist into tuesday morning. then as 
the center of low pressure deepens to around 29.1 inches while it
tracks into the hudson bay region well north of lake michigan, it
will drag a cold front across the lake through tuesday morning. 
as the front quickly exits the region, winds will gradually weaken
through the day tuesday as they briefly shift to the west while 
another area of high pressure skirts just south of lake michigan 
tuesday night. then expect another low pressure to lift into the 
region from the southern plains for the middle of the week 
bringing another round of gusty winds over the open waters 
through the end of the week.
