the highest 1/10 of the wave spectrum.

.synopsis...a ridge averaging 30.5 inches affects the lake through

ridge then exits southeastward as a weak cold front sweeps 
southeastward across the lake on monday. behind the front, another 
ridge averaging 30.5 inches should build from central canada and 
vicinity through this tuesday.
