317 am 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 around 29.4 inches will continue to track from lake 
superior through the james bay region and into quebec today. 
breezy southwesterly winds with gusts up to 30 knots will persist 
this morning before increasing and briefly turning westerly this 
afternoon as the associated cold front slides across lake 
michigan. then stronger winds shift to the north-northwest behind
the cold front this evening/tonight. will see gusts increase to
gale force during this time and continue 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 and warmer lake 
temps, cannot rule out an isolated waterspout or two for southeast
part of the lake michigan. then high pressure will build over the
upper great lakes overnight friday through the weekend bringing 
lighter northwesterly winds
