open lake forecast for lake huron
national weather service detroit/pontiac mi
341 pm est mon mar 2 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 over the northeast governs conditions
across the central great lakes this evening as winds decline. an
area of troughing extends eastward through the ohio valley
offering potential for a bit of freezing drizzle across parts of
lake st. clair and western erie early tuesday morning before
changing over to liquid rain midday. dry weather and light winds
return wednesday morning as high pressure briefly spills across
lower michigan. winds pick back up by thursday as a rain
producing warm low lifts into the south while canadian high
pressure builds into james bay.

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 around 29.5 inches will move east into hudson bay
today, with high pressure around 30.6 inches moving east through
the northeastern conus. this will drive breezy south to southeast
winds across lake michigan today, particularly over the northern
third of the lake where gusts to 30 knots are possible. winds will
subside tonight into tuesday as both pressure systems depart 
eastward, with light and variable winds tuesday afternoon through
tuesday night. 

light east to northeast winds develop into wednesday as weak low
pressure around 29.9 inches develops over the central great
plains, tracking northeastward through the middle mississippi
river valley. the low will approach and ultimately pass near or 
just south of the southern portions of the lake on thursday. east
to northeast winds will linger. periods of rain will accompany 
the low wednesday night into thursday, with a few thunderstorms 
possible over southern lake michigan wednesday afternoon and 
evening. 

another low pressure system around 29.5 inches will form in the 
central great plains thursday night, and is forecast to progress 
toward the upper mississippi river valley during the day on 
friday. the approach of the low will bring increasing south to
southeasterly winds to the open waters on friday, along with 
widespread areas of rain and embedded thunderstorms. 

the low will move northeast across the region and into ontario
friday night through saturday, dragging a cold front across lake
michigan in the process. additional rain is expected during the 
frontal passage. winds will veer southwest to west as the front 
passes.

.synopsis...

a 30.6 high currently centered over lake ontario continues to shift

hudson bay, deepening to 29.6 inches. the low drags a weak trough of 
30.2 inches over lake superior tonight before weak ridging builds 
over the lake on tuesday as another, more compact high of 30.4 
inches moves to james bay. another large area of high pressure will 
move into central and eastern canada by thursday morning. the strong 
high will help keep a 29.7 inch low moving up from the southern 
plains to our south as it weakens to 29.9 inches by the time it 
reaches the lower great lakes wednesday night, dissipating 
thereafter.

for waters beyond 5 nautical miles of shore on lake superior.

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 30.6 high currently centered over lake ontario continues to shift 
east today as a 29.7 inch low over northern manitoba moves east over 
hudson bay, deepening to 29.6 inches. the low drags a weak trough of 
30.2 inches over lake superior tonight before weak ridging builds 
over the lake on tuesday as another, more compact high of 30.4 
inches moves to james bay. another large area of high pressure will 
move into central and eastern canada by thursday morning. the strong 
high will help keep a 29.7 inch low moving up from the southern 
plains to our south as it weakens to 29.9 inches by the time it 
reaches the lower great lakes wednesday night, dissipating 
thereafter.
