inches on monday, strengthening to 30.5 inches over quebec by 
tuesday. as this occurs, ridging over lake superior will strengthen 
from 30.1 inches sunday night to 30.4 inches monday night into 
tuesday. ridging then weakens to 30.1 inches over the lake on 
wednesday as a 29.7 inch trough crosses hudson bay.

national weather service marquette mi
1001 pm edt sat oct 17 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...

30.5 inch high pressure spans from new england to texas tonight 
while a 29.2 inch low moves over hudson bay, with lake superior 
around 30.0 inches through sunday between these features. high 
pressure gradually strengthens to 30.6 inches over the canadian 
maritimes through monday as 30.4 inch ridge extends southwest to the 
tennessee valley. meanwhile, 30.2 inch high pressure builds over the 
northern plains sunday night and tracks east across ontario at 30.4 
inches on monday, strengthening to 30.5 inches over quebec by 
tuesday. as this occurs, ridging over lake superior will strengthen 
from 30.1 inches sunday night to 30.4 inches monday night into 
tuesday. ridging then weakens to 30.1 inches over the lake on 
wednesday as a 29.7 inch trough crosses hudson bay.
