open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
854 am cst mon nov 10 2025

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 of 30.7 inches over the central great plains will 
continue southeastward today, weakening to 30.5 inches and 
arriving at the gulf coast by tonight. a convergent band of lake
effect snow and potential for a few waterspouts is lingering
northeast to southwest across the lake, with winds on the 
southeast side of the band northeasterly and winds on the 
northwest side of the band becoming northwesterly and gusty. a few
northwesterly gales are possible late this morning into this
afternoon before diminishing tonight. waterspout potential also
ends as the lake effect snow band moves eastward overnight.

a trough of low pressure around 29.4 inches sags south into 
ontario canada, bringing increasing southwest winds. southwest 
gales are likely tuesday over the south half of the lake. winds 
turn west and remain gusty tuesday night into wednesday as low 
pressure tracks east through ontario canada and drags a cold front
across the lake. these winds may also approach or reach gale 
force. lighter winds expected thursday as weak high pressure moves
through the region.
