840 am cdt fri oct 9 2026

for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

high pressure around 30.1 inches will exit into this afternoon,
allowing for winds to become southeasterly. winds shift to
southerly tonight as the high moves to the east and low pressure 
around 29.2 inches develops the northern plains. a tight pressure
gradient over lake michigan will produce southerly winds gusting up
to 30 knots from tonight through sunday morning. a few gale force
gusts may occur in the northern half of the lake saturday 
afternoon and evening. gale warnings are not expected at this 
time.

lighter winds are expected by monday, as a weak low pressure 
trough around 29.7 inches slowly moves from minnesota to 
wisconsin. look for gusty northwest to north winds to develop 
monday night into tuesday after the passage of a cold front, as 
high pressure around 30.1 inches builds into the upper midwest.

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 surface high has built over the ohio river valley this 
morning, resulting in 30.1 inch ridging over lake superior. this 
ridge is separating a pair of 29.4 inch lows, one over southern 
alberta and one off the labrador coast. throughout the day and into 
saturday morning, the high will build to 30.4 inches over new york 
as the alberta low moves to southern saskatchewan and the north 
plains. meanwhile, 29.7 inch hurricane isaias will move up the 
alabama/mississippi state line, eventually helping to kick the high 
east as it weakens. by early sunday morning, the canada low will 
split into 2 weaker 29.6 inch lows, one settling over the central 
plains and one moving from northern minnesota to northern ontario. 
this will create weak 29.8 inch troughing over lake superior for 
sunday, deepening to 29.7 inches by monday evening. meanwhile, the 
high will shift to the new england coastline then over the atlantic, 
ushered east by the tropical remnants at 29.9 inches as they move 
into the ohio river valley. the colorado low crosses the great lakes 
basin early next week, followed by 30.2 inch high pressure for the 
midweek.

morning, resulting in 30.1 inch ridging over lake superior. this 
ridge is separating a pair of 29.4 inch lows, one over southern 
alberta and one off the labrador coast. throughout the day and into 
saturday morning, the high will build to 30.4 inches over new york 
as the alberta low moves to southern saskatchewan and the north 
plains. meanwhile, 29.7 inch hurricane isaias will move up the 
alabama/mississippi state line, eventually helping to kick the high 
east as it weakens. by early sunday morning, the canada low will 
split into 2 weaker 29.6 inch lows, one settling over the central 
plains and one moving from northern minnesota to northern ontario. 
this will create weak 29.8 inch troughing over lake superior for 
sunday, deepening to 29.7 inches by monday evening. meanwhile, the 
high will shift to the new england coastline then over the atlantic, 
ushered east by the tropical remnants at 29.9 inches as they move 
into the ohio river valley. the colorado low crosses the great lakes 
basin early next week, followed by 30.2 inch high pressure for the 
midweek.
