open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
902 pm cdt thu apr 25 2024

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...

light winds continue as high pressure around 30.4 inches 
gradually slides into the eastern great lakes tonight. meanwhile 
a low pressure around 29.3 inches develops in the central plains 
overnight and slides east bringing, increasing southeasterly 
winds across lake michigan for friday. expect stronger 
southeasterly winds with a potential for a few, brief gale force 
gusts to persist as the low pressure lifts into mn friday night 
and saturday. this low will weaken as it lifts further northeast 
through the day saturday before another, stronger low pressure 
system around 29.5 inches develops over the plains and lifts 
northeast across the great lakes region sunday into monday. this 
looks to bring another round of gusty winds to the lake.

showers and thunderstorms are possible friday night through 
sunday night, with the best chances for thunderstorms friday 
night, saturday afternoon and night, and sunday afternoon and 
night.
