open lake forecast for lake huron
national weather service detroit/pontiac mi
947 am edt wed jul 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...high pressure will wash out across the appalachia
region today which will veer winds to the south and southwest
over the great lakes. a cold front will then push through the
great lakes thursday and bring increasing coverage of showers and
embedded thunderstorms. lingering shower and storm chances
continue friday across the southern great lakes.
