open lake forecast for lake huron
national weather service detroit/pontiac mi
1000 pm est mon nov 2 2026

for waters beyond five nautical miles off shore on lake huron

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 slow moving deepening low pressure system will move
into the upper midwest by tuesday. this will result in increasing
southerly winds topping out in the 20 to 30 knot range. this
system will drag a slow moving cold front into the great lakes
region tuesday night into wednesday as the low weakens and tracks
through lake superior on thursday.

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

.synopsis...

low pressure near 29.4 inches will progress into the upper 
mississippi river valley by early tomorrow morning. winds will 
steadily become gusty ahead of the low, approaching or exceeding 
gale force over at least the central third of the lake late 
tuesday morning and tuesday afternoon. a gale warning is now in 
effect over this portion of the waters between 9 am-6 pm cst 
tuesday. rain will accompany the approaching/passing low tonight 
through tuesday night, with a few thunderstorms possibly mixing 
in. severe weather is not expected at this time. 

29.5 inch low pressure will stagnate over northern wisconsin on 
wednesday, steadily progressing from lake superior into quebec 
wednesday night into friday morning. progression of the low will 
result in a gradual trend toward westerly and eventually 
northwesterly winds thursday into friday. winds will be breezy 
through this time frame, though they are expected to remain below 
gale thresholds. winds will taper by the weekend as 30.0 inch 
high pressure builds into the western great lakes.
