open lake forecast for lake huron
national weather service detroit/pontiac mi
356 pm est sun nov 8 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...ontario low pressure, 29.50 inches, is on-track to
cross into western quebec this evening, with its cold front
draped southwestward. the front works across the central great 
lakes during the overnight hours. expect some showers at times, 
mainly over lake huron. the pattern quickly shifts as high 
pressure briefly builds in monday. troughing returns tuesday as 
the next clipper brushes the northern shores of lake superior, 
with its attendant cold front passing through. note that the 
frontal passage is expected to be mainly dry. high pressure then 
returns tuesday night into wednesday.
