open lake forecast for lake huron
national weather service detroit/pontiac mi
922 pm edt tue mar 10 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...an elongated trough axis expands into the southern
great lakes late today. a more active stretch of weather gets 
underway tonight into wednesday as low pressure, 29.50 inches, 
lifts across lower michigan. expect several rounds of showers and 
thunderstorms, including some strong to severe storms. all severe 
hazards will be possible. the system's frontal passage eventually 
leads to a transition to melting snowfall by wednesday evening. 
seasonably cool conditions ensue thursday, followed by more rain, 
snow, and wind with another system on friday.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

low pressure of 29.6 inches in northern illinois this evening, 
reaching southwest michigan early wednesday morning. northeast 
winds will become northerly tonight as the low passes over far 
southern lake michigan. gusty northwest winds are likely wednesday
into wednesday evening behind the low. not out of the question 
for a few gusts to 35 knots during this period, particularly 
across eastern portions of the lake. confidence for widespread 
gales isn't high enough at this point though for a gale watch or 
warning. 

lighter winds are likely wednesday night into early thursday as
high pressure of 30.2 inches briefly moves through. strong low
pressure of 29.1 inches is then expected to move through northern
wisconsin into northern michigan thursday night into friday.
increasing southerly winds are expected later thursday into
thursday night ahead of the low. though the cold lake may dampen
the gust potential thursday night, southerly gales will still be
possible. there is a better chance for west to northwest gales on
friday behind the low. could even see a few gusts approach storm
force per latest models. 

winds are expected to ease friday night into saturday as high 
pressure of 30.2 inches moves in from the northwest. another
strong low pressure system is likely to move through the region
late in the weekend into early next week, with another round of
gales possible.
