open lake forecast for lake huron
national weather service detroit/pontiac mi
345 am est wed nov 11 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 influence gradually exits the central
great lakes today while the next low pressure system deepens and
takes aim at the ohio valley. showers, with potential for mixed
precipitation, linger into the weekend as larger scale troughing
persists.

311 am cst wed nov 11 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...

29.8 inch low pressure taking shape over iowa will deepen to 29.6
inches as it tracks to indiana by early evening. the low will 
quickly advance through the northeastern united states on 
thursday. progression of the low and upper level disturbances
rolling across the upper great lakes will result in steady 
increases in northerly winds this evening through thursday. wind 
gusts should eventually exceed gale thresholds for the southern 
two thirds of lake michigan by early thursday morning. the gale
watch was upgraded to a gale warning. 

northerly winds will remain steadily breezy, though below gale 
thresholds, through the day on friday as strong high pressure
around 30.3 inches over ontario drifts toward the hudson bay. 
winds will taper sunday into monday as 30.5 inch high pressure 
builds directly over the open waters. 

persistent northerly winds will allow for the development of a band 
of lake effect precipitation thursday through friday. current 
forecast guidance has shifted that the band more toward the
western half of the lake on thursday, and the center/east half on
friday. low level temperatures will be supportive for mainly 
rain, though some snow could mix in over the northern half of the 
lake. given the deep mixing depth and high water-air temperature
difference, there is an increasing waterspout potential during 
this period.
