open lake forecast for lake huron
national weather service detroit/pontiac mi
357 am edt sat may 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.

lakes today while concurrently a weak diffuse high pressure
system builds in. this will promote another day of lighter
northwest flow. a warm front enters sunday, backing winds from 
northwest to southwest.
