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.

30.6 inch ridging over lake superior this gradually weakens to 30.3

a 29.8 inch clipper low crosses the lake monday night into tuesday. 
another clipper low, much weaker at 30.1 inches, grazes the 
northeast portion of the lake on wednesday. a strong high pressure 
descending from the canadian prairie around 30.7 inches late next 
week brings ridging back to lake superior, likely persisting into 
next weekend.

open lake forecast for lake superior
national weather service marquette mi
1000 pm est sat jan 24 2026

for waters beyond 5 nautical miles of shore on lake superior.

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...

30.6 inch ridging over lake superior this gradually weakens to 30.3 
inches into tomorrow, then further to around 30.1 inches into 
monday, as a 29.6 inch low moves northeast along the atlantic coast. 
a 29.8 inch clipper low crosses the lake monday night into tuesday. 
another clipper low, much weaker at 30.1 inches, grazes the 
northeast portion of the lake on wednesday. a strong high pressure 
descending from the canadian prairie around 30.7 inches late next 
week brings ridging back to lake superior, likely persisting into 
next weekend.
