open lake forecast for lake huron
national weather service detroit/pontiac mi
946 am est sun jan 25 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...snow will continue across the southern great lakes as
an expansive low pressure system, 29.7 inches, moves across the 
appalachia region. arctic air is then reinforced in the wake of 
the low pressure system which will increase winds through the 
early week period.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
904 am cst sun jan 25 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...

30.5 inch high pressure is entrenched across northern wisconsin 
this morning, with a band of lake effect snow ongoing over west- 
central portions of the open waters. the two features are thus 
contributing to east-northeast winds over eastern lake michigan 
with west-northwest winds further west. the surface pressure drop
affiliated with the lake effect snow band will continue to 
sharpen today as a new area of 30.7 inch high pressure builds 
into the northern great plains, resulting in increasing wind gusts
from late morning into the afternoon hours. gusts between 25-30 
knots are possible over the southern half of the waters, though 
they should remain below gale thresholds. snow will continue 
through this afternoon.

low pressure of 29.5 inches will move from the appalachian 
mountains into the northeastern united states tonight as 30.7 inch 
high pressure builds further into the central and southern great 
plains. progression of the two features will maintain breezy 
northwest winds over the open waters, with additional periods of 
25-30 knot gusts possible into monday morning across the southern 
half of the lake. 30.5 inch high pressure will build into the 
ohio river valley monday afternoon and night as 29.8 inch low 
pressure attempts to form over lake superior, resulting in a west-
southwest wind shift across lake michigan. winds will become 
gusty at times monday night into tuesday morning, when a few gales
are possible over the southern third of the open waters. while 
gales are not expected to be widespread at this time, trends will
continue to be monitored for potential headlines in coming 
forecasts.

winds will trend west-northwesterly tuesday afternoon and night as 
30.4 inch high pressure builds into the northern great plains. 
winds will gradually taper wednesday through thursday as said area
of high pressure moves into the upper mississippi river valley. 
elevated waves and cold temperatures will support moderate to 
heavy freezing spray tonight through tuesday afternoon, with a 
heavy freezing spray warning remaining in effect between 6 pm cst 
this evening and 6 pm cst tuesday.
