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...a strong arctic cold front arrives this afternoon
bringing a period of increased southwesterly flow ahead of it and
briefly stronger northwest winds in its wake tonight into
thursday morning. much colder air moves into the region which
activates lake effect snow showers and is favorable for freezing
spray through the late week period.

open lake forecast for lake superior
national weather service marquette mi
400 pm est wed dec 3 2025

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...

30.5 inch high pressure over the dakotas this evening will shift 
east to the lower great lakes through thursday evening, sending a 
30.2 inch ridge over lake superior tonight and thursday. meanwhile, 
a 29.7 inch low will move over lake winnipeg on thursday before 
passing north of lake superior overnight into friday. another 29.6 
inch trough will pass over the lake friday night, extending from a 
29.4 inch low over hudson bay. as the trough shifts east, another 
30.5 inch high builds over the northern plains and shifts east 
across the great lakes through the weekend ahead of the next clipper 
low on monday.
