national weather service marquette mi
1001 pm est thu nov 6 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...

a 29.5 inch low over minnesota this evening will move across upper 
michigan tonight to near whitefish bay at 29.3 inches by late friday 
morning. ridging will build over the lake this weekend as the low 
exits into quebec and 30.6 inch high pressure develops over the 
great plains, with the ridge over the lake strengthening from 29.8 
inches on saturday to 30.2 inches through sunday night. the ridge 
quickly breaks down early next week as a 29.4 inch trough sweeps 
across the lake on tuesday.
