open lake forecast for lake huron
national weather service detroit/pontiac mi
947 pm est thu jan 15 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...two main low pressure systems affect the great lakes
over the next few days. the first system moves in from central
canada early friday morning to near the west end of lake superior
at 29.50 inches by the afternoon. it dominates the weather across
the great lakes with a wide range of conditions. temperatures
moderate in the first phase of the system as a pattern of snow
moves across lake huron and lower mi into friday night. this is
followed by a brief period of high pressure and then the second
low pressure system that brings progressively colder conditions
highlighted by a surge of arctic air late sunday through early
next week.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
836 pm cst thu jan 15 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...

breezy southwesterly winds will continue to build over lake 
michigan as low pressure around 29.4 inches over western ontario
moves to the northern great lakes on friday. the low will then
gradually weaken over the northern great lakes into saturday. 
the breezy southwest winds will shift westerly friday afternoon
with the passage of a cold front.

winds are then expected to return to southwesterly and increase 
for sunday as another low pressure deepens to around 29.4 inches 
as it tracks into the lake superior region sunday 
afternoon/evening. the associated cold front will sweep across 
lake michigan as the low pressure quickly pushes east into monday.
expecting stronger northwesterly winds to develop behind the 
departing low and cold front sunday night through monday. there 
will be a potential for gales during this time frame and will 
monitor to see if this gale trend continues. otherwise, low 
pressure kicks east later monday with another high pressure 
building into the region for tuesday.

given the colder arctic airmass settling over the area and brisk 
winds, expect freezing spray concerns across lake michigan this 
weekend and continuing into the next week as well with even colder
temps.

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 29.3 inch low over northwestern ontario drops south to western 
lake superior by friday morning, weakening to 29.4 inches. this low 
slowly meanders over upper michigan friday into saturday morning, 
further weakening to 29.8 inches saturday afternoon when it reaches 
just north of gregorian bay. meanwhile, a 30.4 inch high sets up 
over the plains. as the low remains relatively stationary and 
weakens to 29.9 inches through sunday, the high settles toward the 
southeast u.s., briefly extending 29.9 inch ridging over lake 
superior late saturday night. this quickly is replaced by a clipper 
low of at least 29.5 inches on sunday. the low continues to quebec 
on monday as it deepens to 29.5 inches while another high pressure 
of 30.5 inches drops south over the plains. ridging of at least 30.0 
inches looks to briefly return to the upper great lakes on tuesday.
