open lake forecast for lake superior
national weather service marquette mi

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 quick moving 29.9 inch trough is swinging through lake 
superior this evening while a 30.4 inch high pressure builds into 
the dakotas. the high will extend a 30.3 inch ridge over the upper 
great lakes as it moves to the east and southeast on friday, 
reaching the ohio valley by saturday morning. this ridge will be 
followed by a 29.7 inch trough on sunday. a 29.6 low will develop in
the south-central plains early monday and will track across lower 
michigan late monday as a 29.4 inch low. the low will continue into
southern ontario and quebec tuesday as it deepens to 29.2 inches
while a 30.5 inch high pressure settles in over the northern plains.
