open lake forecast for lake huron
national weather service detroit/pontiac mi
942 am est sun nov 9 2025

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 deepening low pressure system moves through the ohio
valley today, producing gusty north to northeast wind as it
passes south of lake erie at around 29.60 inches this afternoon.
this system ushers in an arctic air mass with gusty northwest
flow and snow showers through the early week. gusty southwest
flow follows on tuesday as milder air arrives, then the next
arctic low drops into the northern great lakes on wednesday.
