national weather service milwaukee/sullivan wi
851 am cdt fri oct 16 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...

low pressure will deepen to around 29.4 inches as it shifts into 
the eastern great lakes today. expect northwest to north winds to
strengthen to high-end gales by late this morning, as a strong 
high pressure system around 30.7 inches builds into the plains. a
gale warning remains in effect for all of the open waters of lake
michigan later this morning into tonight.

lake effect showers and a few thunderstorms are possible today 
along the back side of departing low pressure. a few waterspouts 
are possible in the showers and thunderstorms, particularly over 
the south half of lake michigan. 

as the high sinks toward the ohio river valley on saturday, 
strong low pressure around 29.0 inches will develop in northern 
manitoba into sunday. this may bring southwest gales to far
northern portions of lake michigan saturday night into sunday
night.

open lake forecast for lake superior
national weather service marquette mi
1001 am edt fri oct 16 2026

for waters beyond 5 nautical miles of shore on lake superior.

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 30.8 inch high moving through the plains today weakens to 30.6 
inches as it continues eastward. this weakening is expected to bring 
30.4 inch ridging over lake superior by this evening. the high then 
slides south of the great lakes at 30.5 inches by saturday night as 
a 29.2 inch alberta clipper moves through the northern canadian 
prairie provinces towards hudson bay, deepening to 29.0 inches by 
the time it arrives at hudson bay on sunday. this low is expected to 
bring weak 30.0 inch troughing to northern lake superior throughout 
the day sunday. as the low continues east over hudson bay and 
weakens with time sunday night into monday afternoon, expect high 
pressure ridging of 30.3 inches to return to the upper great lakes 
by monday. the high pressure ridging strengthens to 30.4 inches over 
lake superior by tuesday as the now 30.5 inch parent high over 
northern ontario continues east into northern quebec, deepening to 
30.6 inches as it does so.

open lake forecast for lake superior
national weather service marquette mi
1001 am edt fri oct 16 2026

for waters beyond 5 nautical miles of shore on lake superior.

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 30.8 inch high moving through the plains today weakens to 30.6 
inches as it continues eastward. this weakening is expected to bring 
30.4 inch ridging over lake superior by this evening. the high then 
slides south of the great lakes at 30.5 inches by saturday night as 
a 29.2 inch alberta clipper moves through the northern canadian 
prairie provinces towards hudson bay, deepening to 29.0 inches by 
the time it arrives at hudson bay on sunday. this low is expected to 
bring weak 30.0 inch troughing to northern lake superior throughout 
the day sunday. as the low continues east over hudson bay and 
weakens with time sunday night into monday afternoon, expect high 
pressure ridging of 30.3 inches to return to the upper great lakes 
by monday. the high pressure ridging strengthens to 30.4 inches over 
lake superior by tuesday as the now 30.5 inch parent high over 
northern ontario continues east into northern quebec, deepening to 
30.6 inches as it does so.
