for waters beyond five nautical miles of shore on lake ontario

waves are the significant wave height - the average of the highest

.synopsis...a ridge of high pressure averaging 30.4 inches 
over the lake will slowly drift to the east through tonight and 
sunday, before drifting off the new england coast sunday night. this 
will open the door for a cold front to sweep southward across the 
lake sunday night, with a ridge averaging 30.4 inches building in 
from northern ontario through monday. by monday night through 
tuesday, a low of 30.0 inches should move from near the lower ohio 
valley toward the mid-atlantic states and extend a weak trough 
averaging 30.3 inches over the eastern great lakes. meanwhile, a 
strong 30.6 inch high over quebec tuesday will then ridge south 
across the lake from tuesday night through at least thursday.
