open lake forecast for lake huron
national weather service detroit/pontiac mi
340 am est fri jan 16 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...low pressure, 29.40 inches, weakens slightly as it 
tracks across the northern great lakes today. this systems brings 
an expanding coverage of snow through the day before a transition 
to snow showers tonight as colder air works in from the southwest.
this is followed by a brief period of high pressure and then a 
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
247 am cst fri jan 16 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 today, as low pressure around 29.4 inches over western 
ontario moves to the northern lake michigan today. the low will 
then gradually weaken as it shifts into northern lake huron 
tonight and eastern ontario on saturday. the breezy southwest 
winds will shift westerly by early this evening, with the passage 
of a cold front. these winds will linger into saturday night.

winds are then expected to return to the southwest and increase 
for sunday, as another low pressure system strengthens to around 
29.4 inches as it tracks into the lake superior sunday 
afternoon and evening. the associated cold front will sweep 
across lake michigan, as the low quickly pushes east into monday.

stronger northwesterly winds are expected to develop behind the 
departing low and cold front sunday night through monday. there 
will be a potential for gales during this time frame along with 
building waves. otherwise, low pressure around 29.5 inches shifts 
east later monday, with high pressure around 30.5 inches remaining
to the southwest and south of the region monday night into 
tuesday.

given the colder arctic airmass settling over the region and the 
brisk winds, expect freezing spray across lake michigan this 
weekend and continuing into next week. some heavy freezing spray
may be possible sunday night into monday.
