open lake forecast for lake huron
national weather service detroit/pontiac mi
1002 am edt sat mar 14 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...high pressure, 30.20 inches, briefly builds back in on
today, diminishing wind speeds and gust potential through the
morning. a second anomalously strong low pressure system, 28.90
inches, moves across southern michigan and lake huron late sunday
into monday. this brings renewed chances for prolonged gales and
winter weather.

858 am cdt sat mar 14 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...

lighter winds are expected this morning as high pressure of 30.2 
inches moves through. the high slides east later today and east- 
northeast winds will steadily increase tonight through sunday, as 
a low pressure system around 29.3 inches forms in the central 
great plains. the low will progress over far southern lake 
michigan sunday evening as it deepens to around 29.1 inches, 
resulting in strong northerly winds developing.

strong winds will shift out of the northwest monday, as the 
strong low continues to move into ontario. expect another 
prolonged period of gales and storm force gusts, across all of 
the open waters and nearshore waters early sunday morning through 
monday night at various directions as the low progresses through 
the region. gale watches or storm watches continue for this 
timeframe.

prolonged snow is expected saturday night through monday, some of
which could be heavy over northern portions of the lake. sleet or
freezing rain should mix in with rain and snow over central and
parts of northern lake michigan saturday night into sunday, with 
mainly rain and perhaps a few thunderstorms in the far southern 
portions of the lake sunday into sunday evening. snow is then 
expected over southern portions of the lake sunday night into 
monday night.

freezing spray potential will increase monday and linger into
tuesday behind the departing low, with areas of moderate to heavy
freezing spray possible. the heavy freezing spray watch continues.
