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...

troughing resides over eastern lake superior at 29.6 inches this 
morning associated with a parent low of 29.3 inches over james bay. 
the 29.6 inch trough over the lake then leaves to the east today, 
allowing a 30.5 inch high to move over the lake from the northwest 
by saturday. the high shifts east through sunday in advance of a 
clipper low arriving over far western lake superior at 29.8 inches 
by monday morning. because this clipper low deteriorates over the 
upper great lakes on monday, weak ridging of 30.0 inches returns 
over lake superior on tuesday.
