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...

winds will continue to weaken today into tonight across lake 
michigan, as weak high pressure around 30.3 inches develops over
the area. an upper disturbance crossing the region this morning 
may bring light rain and light freezing rain or drizzle to the 
southern half of lake michigan.

light south to southwesterly winds will continue across the 
northern half of lake michigan into wednesday, while winds shift 
out of the east further south in response to developing low
pressure around 29.9 inches in the middle mississippi river 
valley. this low will likely pass just to the south of lake 
michigan wednesday night into thursday, allowing for east to
northeast winds to become established. 

rain showers will spread north across the open waters in response
to the passing low pressure system later wednesday night through 
thursday. a few thunderstorms are possible over far southern lake
michigan thursday. 

low pressure around 29.5 inches remains forecast to develop in 
the central great plains thursday night, and is expected to be 
somewhere between the upper mississippi river valley and northern
wisconsin by friday evening. this low will move near or just 
north of northern lake michigan later friday night into saturday 
morning, quickly moving into quebec by saturday evening. 

south to southwest winds will thus steadily increase ahead of the
developing and approaching low friday afternoon into saturday 
morning, ultimately veering westerly saturday afternoon. winds 
will be gusty at times during this period, with a few gales 
possible friday night into saturday morning. widespread rain and 
embedded thunderstorms will accompany the approaching and passing 
low friday through saturday.

open lake forecast for lake superior
national weather service marquette mi
400 am est tue mar 3 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 30.1 inch trough will remain over the lake today with ridging of 
30.2 inches building in tonight. a large area of high pressure will 
move into central and eastern canada wednesday into thursday 
morning. the strong high will help keep a 29.7 inch low moving up 
from the southern plains to our south as it weakens to 29.6 inches 
by the time it reaches the lower great lakes wednesday night, 
dissipating thereafter. on friday low pressure ejects out of the 
plains, reaching lake superior saturday morning at least at 29.8 
inches. behind the low a 29.9 inch ridge builds over the lake on 
saturday night before a stronger, 29.2 inch, low moves through 
central ontario on sunday.
