open lake forecast for lake huron
national weather service detroit/pontiac mi
357 pm est mon jan 12 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...mild temperatures are in place between larger scale 
weather systems today which continues tonight as the next low 
pressure system, 29.20 inches, moves toward the great lakes. this 
system moves across ontario tuesday and brings a light rain and 
snow mix to lake huron and lower michigan. the low 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.
