open lake forecast for lake huron
national weather service detroit/pontiac mi
944 pm est sun jan 11 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...less windy tonight with a bit of light snow possible
for northern lake huron. mild and breezy monday and tuesday ahead
of the next low pressure system, 29.20 inches, with rain moving
in tuesday morning. the low slowly pivots through the region
tuesday night into wednesday, eventually forcing a cold frontal
passage. this leads to a changeover to snow with the possibility
for a period of post- frontal gales late wednesday.
