Waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. Occasional wave height is the

.SYNOPSIS...Lake Superior is currently situated between a broad
30.4 inch high over New England and a 29.3 inch low over 
Nebraska. The low will track northeast, weakening to 29.6 inches 
by the time it reaches northeast Lake Superior on Saturday 
evening. On Sunday, 30.4 inch high pressure will build over 
northern Ontario as a 29.6 inch low pressure lifts northeast 
across the Central Plains. This low will continue to track 
northeast, crossing western Lake Superior late in the day Monday
at 29.7 inches. As the low moves over northern Ontario Monday 
night, a weak 30.0 inch ridge will shift east across the 
Mississippi Valley. On Tuesday, the ridge will shift toward the 
Appalachians as the next low pressure of 29.5 inches tracks from 
North Dakota to far northern Minnesota, passing north of Lake
Superior Wednesday.
