waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of

cold front is expected to sweep southeastward across the lake 
this evening through tonight. behind the front, a ridge averaging

great lakes toward lake ontario. this should allow a warm front to
sweep northward across lake erie tuesday night through wednesday 
morning and a cold front to sweep eastward across the lake later 
on wednesday.
