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

average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

broad low pressure of 29.6 inches will slowly move across the 
northern great lakes this afternoon and evening. its weak and
decaying cold front will then follow for saturday afternoon. thus
modest south winds today will shift west to southwest tonight and
saturday morning, followed by light and variable winds saturday
afternoon. during this time, areas of dense fog will be possible
due to humid air flowing over the cold lake. light northeast 
winds will then prevail saturday night and sunday as high 
pressure around 30.0 inches builds across the region. looking 
ahead, the start of next week will bring an additional low 
pressure system to develop over the great plains and approach
lake michigan with modest southeasterly winds expected.
