open lake forecast for lake ontario
national weather service buffalo ny
1035 pm edt fri may 3 2024

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 30.2 inch high will settle along the new england coast 
by this evening. meanwhile, a 29.6 inch low across the southcentral 
canadian prairies will move north into far northwestern ontario 
province by this evening. this same low will continue to slowly 
deepen to 29.5 inches as it drifts further north tonight, settling 
over southern hudson bay on saturday. a slow moving cold front 
extending southeastward from the low will approach the lake 
tonight, before stalling to the west of the lake saturday. a 
stronger second cold front will then move across the lake sunday.
a 30.2 inch ridge of high pressure will then build in across the 
lake monday into tuesday.
