open lake forecast for lake huron
national weather service detroit/pontiac mi
943 pm est sun nov 1 2026

for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...a slow moving deepening low pressure system will move
from the central plains monday to northern minnesota tuesday.
this will result in increasing southerly winds topping out in the
20 to 30 knot range. this system will drag a slow moving cold
front into the great lakes region tuesday night into wednesday as
the low weakens and tracks through lake superior on thursday.

open lake forecast for lake michigan
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.
