35 to 40 kts, with a few isolated gusts to 45 kts possible. 

high pressure around 30.4 inches will build into the great lakes 
region from canada tonight into monday bringing decreasing winds
with northerly gales falling off this evening. as this high exits
tuesday and a weak front passes, winds may pick up a bit from the
south. winds over the lake will remain largely from the south 
through wednesday as broad low pressure approaches from the west. 
chances for precipitation on tuesday and again on wednesday though
primarily for northern parts of the lake.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
907 am cdt sun mar 22 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...

low pressure around 29.5 inches will continue east across the 
southern great lakes region this morning. as this low pushes out,
the pressure gradient strengthens as winds from the north become
gusty. gales have developed quickly this morning and have become 
more persistent across the southern third of the lake. thus a 
gale warning has been issued through the evening for gusts from 
35 to 40 kts, with a few isolated gusts to 45 kts possible. 

high pressure around 30.4 inches will build into the great lakes 
region from canada tonight into monday bringing decreasing winds
with northerly gales falling off this evening. as this high exits
tuesday and a weak front passes, winds may pick up a bit from the
south. winds over the lake will remain largely from the south 
through wednesday as broad low pressure approaches from the west. 
chances for precipitation on tuesday and again on wednesday though
primarily for northern parts of the lake.
