Open Lake Forecast for Lake Ontario
National Weather Service Buffalo NY

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...An expansive 30.2 inch high will settle across the
Mid-Atlantic coast this evening. A 29.5 inch low will then slowly
cross the Upper Great Lakes tonight and Thursday. This low will 
push a warm front across the lake Thursday...with the front 
oscillating back and forth over the region Friday and Saturday. A 
deepening area of low pressure to 29.4 inches will lift northward 
across the Central Great Lakes Saturday and to near James Bay 
Sunday, while pushing the oscillating frontal boundary eastward of
the lake as a cold front Saturday night. Then a 30.0 inch high
will build across the mid-west Sunday and nudge into the Lower
Great Lakes on Monday.
