waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the

down across the lake.

northwest to north winds will continue across the lake into early

especially sunday afternoon through monday morning. light and 
variable winds are then expected into monday evening as the polar
high weakens and drifts overhead. a modest south breeze develops 
tuesday as weak high pressure drifts east of the region and low 
pressure develops west of the lake.
