national weather service milwaukee/sullivan wi
859 pm cst sun nov 1 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 around 30.5 inches will linger over the mid 
atlantic states through dawn monday morning before beginning a 
slow eastward retreat into the atlantic ocean. light south to 
southeasterly winds continue through predawn monday morning, 
accelerating later monday morning as low pressure around 29.4 
inches lifts northeast across south dakota. winds will steadily 
become gusty ahead of the incoming low pressure, approaching or 
exceeding gale force over the central third of the lake tuesday 
afternoon and evening. headlines may become necessary in later 
forecasts. rain will accompany this low pressure system monday 
night through wednesday, with a few thunderstorms possibly mixing 
in. severe weather is not expected at this time.

low pressure is expected to stall near the upper peninsula of 
michigan / lake superior midweek, leading to continued breezy 
south winds across lake michigan. the low will make a slow 
eastward exit later in the work week, allowing winds to veer west 
and eventually north. high pressure around 30.2 inches builds into
ontario canada late this week, which should allow winds to 
gradually subside into the weekend.
