for waters beyond five nautical miles of shore on lake ontario

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...
a high pressure ridge averaging 30.2 inches builds from the canadian 
prairies before settling over lake ontario and vicinity by saturday. 
the ridge begins to exit eastward saturday night and a low of 29.7 
inches should move generally east-southeastward from near the 
northern great lakes to near the gulf of maine saturday night 
through monday. this low track should allow a warm front to sweep 
northeastward across lake ontario saturday night and especially on 
sunday before a cold front sweeps eastward across the lake sunday 
evening through sunday night. behind the cold front, a high pressure 
ridge averaging 30.0 inches should build slowly from the upper 
midwest through tuesday.
