open lake forecast for lake ontario
national weather service buffalo ny
1002 am edt fri apr 24 2026

for waters beyond five nautical miles of shore on lake ontario

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

.synopsis...a strong 30.7 inch high centered well to the north will

great lakes this morning will nudge a warm front toward the lake as 
it moves into the central great lakes this afternoon. this low will 
slightly weaken to 29.7 inches as it passes just southwest of lake 
tonight while nudging the warm front a bit further east over the 
lake. the low then slide southeast into the mid atlantic region 
saturday forcing the front back to the southwest of the lake. a 30.2 
inch area of high pressure will build across the lower great lakes 
saturday night through monday. a 29.4 inch area of low pressure over 
the great plains monday night, will advance northeast into the upper 
great lakes later monday night into tuesday morning while pushing an 
attendant warm front across the lake before heading northeast to 
james bay tuesday night sending an attendant cold front across the
