waves are provided as a range of significant wave heights, which

.synopsis...

high pressure of 30.0 inches over the great lakes will strengthen

eventually shifting southward by late in the week ahead of an 
approaching trough of low pressure. northerly winds generally 
under 15 knots through at least saturday will become southerly by 
monday, increasing into early next week as low pressure deepens in
the northern plains.
