national weather service milwaukee/sullivan wi
301 pm cdt sun jun 7 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 of 30.1 inches over the upper great lakes will
gradually begin to shift east through the rest of today and into
monday morning. warm and humid air lingering over the relatively 
cool waters of lake michigan has caused marine dense fog over the 
northern half of the lake into the early part of the afternoon.
recent satellite trends have shown this area of fog dissipating,
so the marine dense fog advisory may be cancelled before 7pm cdt
this evening.

otherwise, broad low pressure over the great plains and high 
pressure over the northeastern states will lead to moderate 
southeast winds over the lake into tuesday morning. winds then
become southerly during the day on tuesday as a warm front lifts
north over the lake.

occasional chances for showers and thunderstorms are in the 
forecast, particularly late monday through monday night.
additional chances later in the week.
