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

.synopsis...today, a 30.0 inch ridge builds over the lake 
associated with a 30.2 inch high over the northern canadian 
prairie provinces. tonight, ridging weakens over the lake as a 
29.7 inch low approaches the southern portions of the great lakes 
basin. as the low moves through southern lake michigan early 
saturday, an inverted 29.8 inch trough will move through lake 
superior. 30.0 inch ridge will return saturday night, then build 
to 30.1 inches sunday night. this ridge will remain over lake 
superior late weekend into early next week. a deepening low 
pressure system moving into the lower midwest sometime monday 
night thorough tuesday will lead to height falls over lake 
superior, but exact timing and track of this system remains 
uncertain.
