921 pm cdt fri apr 10 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...

high pressure around 30.4 inches will continue to build over the 
western great lakes region tonight into saturday morning, causing 
winds to become light and variable. southeast winds return 
saturday afternoon and become gusty saturday night as a sharper 
pressure gradient moves over the lake as low pressure moves into 
the northern great plains.

low pressure will shift into the northern great plains during the
day sunday as it deepens to near 29.4 inches. the low will quickly
shift east toward lake superior sunday night, reaching the
southern shores of the hudson bay by daybreak monday morning.
winds will thus increase further across the open waters sunday
through sunday night. will be monitoring for gale potential
during this time frame, particularly over the northern half of
lake michigan. as of this forecast update, forecast models
continue to suggest possible gales and headlines may be needed in
the coming days. 

winds will weaken monday morning as high pressure of 30.0 inches 
moves across ontario. then, passing low pressure systems will lead
to persistently active conditions across lake michigan into next 
week. will need to monitor thunderstorm development during the 
monday- wednesday time period, as some storms could become strong 
to severe.
