open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
issued by national weather service green bay wi
200 pm cst thu nov 5 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 currently at around 29.6 inches will continue to 
track through the james bay region and into quebec. winds continue  
to increase and turn west/northwesterly this afternoon as the 
associated cold front slides across lake michigan. stronger winds 
then shift to the north-northwest behind the cold front this 
evening. will see gusts increase to gale force during this time, 
continuing into friday as high pressure around 30.3 inches begins 
to build down across the upper midwest. thus, a gale warning 
remains in effect for these strong winds as they work north to 
south down lake michigan late this afternoon through friday 
afternoon. may see gale conditions end sooner for northern portion
of lake michigan. in addition to the winds, cold air moving into 
the region friday paired with warmer lake temps will result in 
potential for an isolated waterspout or two for the southeast part
of lake michigan. high pressure then builds over the upper great 
lakes overnight friday through the weekend, bringing lighter 
northwesterly winds.
