855 pm cst wed feb 11 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...

30.3 inch high pressure is centered over west-central wisconsin 
this evening, with west-northwest winds tapering across the open 
waters of lake michigan. winds will continue to lighten through 
the remainder of the overnight hours into thursday afternoon as 
the aforementioned area of high pressure gradually crosses the 
waters. the high will progress east into appalachian mountains 
thursday night through friday, allowing for light southwesterly 
winds to become established across the lake. generally west- 
southwest winds will continue through saturday as 29.6 inch low 
pressure forms over northern manitoba. low pressure will continue
east across the hudson bay saturday night through sunday morning,
pulling a weak cold front across lake michigan in the process. 
precipitation is not currently anticipated during the frontal 
passage, though winds will briefly shift out of the northwest 
sunday afternoon behind the departing boundary.

winds will trend light & variable sunday night, when 30.1 inch 
high pressure is forecast to move across the open waters. winds 
will trend south to southwesterly monday as the high shifts east, 
with readings steadily increasing through tuesday as 29.5 inch 
low pressure forms over the northern great plains. said low will 
approach and ultimately cross the waters tuesday night through 
wednesday, resulting in a westerly wind shift by wednesday 
afternoon. a few gales are possible tuesday night through 
wednesday morning, though how widespread they would be remains 
uncertain. trends will continue to be monitored in coming 
forecasts. rain will accompany the passing low tuesday night 
through wednesday, with some snow possible over northern lake 
michigan.
