national weather service detroit/pontiac mi
333 am 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...high pressure, 30.50 inches, centered over the eastern
great lakes today, will expand into the mid atlantic on sunday
while increasing to 30.60 inches. this high will influence the
region through the weekend, sustaining relatively light winds. a
slow moving deepening low pressure system will move from the
central plains monday to northern minnesota tuesday. this system
will drag a slow moving cold front into the great lakes region
tuesday night into wednesday as the low lifts into northern
ontario.

open lake forecast for lake michigan

256 am 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 region today, before gradually weakening and shifting 
into the atlantic ocean. this will allow light south to 
southeasterly winds to continue across lake michigan through 
tonight. then low pressure around 29.4 inches will develop over 
eastern co later today and gradually progress into the upper 
mississippi river valley by early tuesday morning. expect 
southerly winds to increase ahead of the approaching low pressure
and gusts over the lake will approach or exceed gale force for 
central portions of lake michigan tuesday. gusty winds could 
continue through midweek as the low pressure slowly meanders 
eastward while high pressure around 30.1 inches slowly builds 
across the canadian plains. then looking at more north and 
westerly winds for thursday as lake michigan sits between the 
slowly departing low pressure and incoming high pressure.
