open lake forecast for lake michigan...corrected
national weather service milwaukee/sullivan wi
913 pm cst fri feb 13 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...

generally west-southwest winds are being observed over lake michigan 
this evening as 30.0 inch high pressure approaches from the upper
mississippi river valley. winds will trend northwesterly to light
& variable overnight as the aforementioned area of high pressure 
approaches the waters. winds will trend south to southwesterly as 
the high shifts east saturday afternoon, increasing slightly 
saturday night as a weak cold front approaches from the west. the 
front will cross the waters sunday morning, bringing a brief 
northwest wind shift into sunday afternoon. winds will trend back 
southwesterly sunday night through monday as 29.8 inch low 
pressure moves toward the hudson bay. 

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 eventually crosses lake michigan. the low will 
progress east of the waters wednesday afternoon & evening, 
resulting in a gusty east-northeast wind shift wednesday night 
through thursday morning. periodic gale force gusts are possible 
tuesday night into wednesday morning, with trends being monitored 
for possible headlines over coming forecasts. rain and snow will 
accompany the approaching/passing low tuesday evening through 
thursday, with a few rumbles of thunder possible tuesday evening 
through wednesday. pockets of light to moderate freezing spray are
possible late wednesday night into thursday morning over the 
northern half of the waters. 

forecast confidence is increasing for a second area of low pressure 
near or below 29.5 inches to develop over the middle mississippi 
river valley thursday evening, with the feature tracking over or 
just south of the southern open waters early friday morning. the 
development and passage of the low would bring increasing east- 
northeast wind gusts thursday night through friday morning, with 
additional gale force gusts possible over the southern half of 
lake michigan. trends will be monitored for potential additional 
headlines over coming forecasts. additional snow will accompany 
the passing low, along with some light to moderate freezing spray.
