open lake forecast for lake huron
national weather service detroit/pontiac mi
issued by national weather service grand rapids mi
857 am 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. aside from a few isolated showers, 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.

258 pm cdt tue mar 10 2026

for waters beyond five nautical miles of shore on lake michigan.

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 near the northern kansas/missouri 
border early this afternoon will head northeast the remainder of
today into tonight, reaching southwest michigan early wednesday
morning. northeast winds will remain breezy today across roughly
the northern two-thirds of the lake, becoming 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.
