open lake forecast for lake huron
national weather service detroit/pontiac mi
942 am est mon dec 9 2024

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 low pressure system lifts across the upper midwest
today, led by the system's surface warm front. expect widespread
rain, with snow near the straits eventually changing to rain,
too. low pressure tracks over lake superior then moves northeast
into ontario/quebec late tonight and tuesday which drives the
surface cold front through the central great lakes. colder air
then filters in through the rest of the week with periods of lake
effect snow wednesday through friday.
