national weather service milwaukee/sullivan wi
232 pm cdt wed oct 28 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 of 29.9 inches will move northeast over lake
superior tonight and to james bay by dawn on thursday, deepening
to 29.5 inches. as the low travels northeast, it is expected to
drag a cold front over the upper great lakes region. breezy
southerly winds are expected to increase this evening as a
tighter pressure gradient moves over the lake. winds will become
southwesterly with time tonight, and gusts will come within a
few knots of gale force over the northern third of lake
michigan. a few gusts to gale force can't be ruled out. some
thunderstorms will also be possible tonight, mainly over the
southern half of the lake. 

the cold front will pass over the lake during the post- dawn 
hours of the morning thursday, bringing winds around to 
northwesterly. winds are expected to ease in strength following
the frontal passage but will remain modestly breezy with gusts
to 20 knots through thursday into thursday night.
