open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
853 am cst sun feb 15 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 is centered near northern lake michigan 
this morning, resulting in weak west-southwest winds across the 
majority of the waters. currently near the mississippi river, 29.9
inch high pressure will approach lake michigan this afternoon, 
allowing winds to become light and variable. 29.7 inch low 
pressure is forecast to form over the northern mississippi river 
valley tonight, allowing winds to veer west-southwesterly as the 
feature approaches during the predawn hours. gusts between 20-25 
knots are possible, but are expected to remain well below gale 
thresholds. winds will weaken later monday afternoon into monday 
night.

stronger low pressure near 29.2 inches will form over the 
northern great plains during the day on tuesday, resulting in 
increasing east to southeasterly winds over lake michigan. winds 
will continue to increase tuesday night into wednesday as the low 
approaches and passes near or north of lake michigan, with wind 
directions veering southwesterly over the southern waters while 
remaining east-southeasterly further north. confidence in a 
period of sustained gale force gusts is beginning to increase over
at least the northern half of the open waters tuesday night into 
wednesday, with the need for possible headlines being evaluated in
coming forecast updates. low pressure will weaken & shift east of
lake michigan later wednesday afternoon into thursday morning, 
resulting in a decrease in wind gusts. rain will accompany the 
passing low tuesday night through wednesday, with a few rumbles of
thunder possible south and some rain-snow mix possible further 
north.

continue to expect a second area of low pressure near or below
29.5 inches to develop over the middle mississippi river valley 
thursday night, with the feature tracking over or just south of 
the southern open waters closer to daybreak friday. the 
development and passage of the low will bring increasing northeast
wind gusts thursday night through friday morning. a few gale 
force gusts are possible. additional snow will accompany the 
passing low, along with some light to moderate freezing spray 
possible late thursday night through early friday. winds will 
shift west-northwesterly friday afternoon through saturday as low 
pressure shifts east and 30.3 inch high pressure builds into the 
northern great plains. winds will remain northwesterly through 
sunday as high pressure moves into the upper mississippi river 
valley.
