national weather service milwaukee/sullivan wi
841 pm cst sun dec 28 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...

low pressure will quickly strengthen to around 28.8 inches as it 
moves northeast through lower michigan into lake huron overnight 
into monday morning. as this strengthening occurs, a very strong 
pressure gradient is expected to move over lake michigan, causing 
widespread northwesterly storm force winds. 

gales should quickly spread northward over the lake, with storm 
force winds then anticipated later tonight into monday afternoon.

winds will back off slightly from storm force to gales late 
monday afternoon and then continue into early tuesday. a storm 
warning has been issued for all of lake michigan tonight into 
early tuesday. after the period of storm force winds and gales, 
breezy northwest flow below gale force will last late into the 
week.
