open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
209 pm cst tue nov 10 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...

30.1 inch high pressure will progress from the upper mississippi 
river valley across the southern open waters through tonight, 
allowing for decreasing west-northwest winds. 29.8 inch low 
pressure will move quickly from the northern great plains into the
ohio river valley on wednesday, quickly advancing into the 
northeastern united states on thursday. progression of the low 
will result in steady increases in northerly winds wednesday 
evening through thursday, with gusts eventually approaching or 
exceeding gale thresholds thursday morning & afternoon as 30.4
inch high pressure builds into the canadian great plains. best 
potential for gales will be over the southern half of the waters, 
where a gale watch is now in effect between 6 am and 6 pm cst 
thursday. northerly winds will remain steadily breezy--- though 
below gale thresholds---through the day on friday as the 
aforementioned high nudges east toward the hudson bay. winds will 
taper sunday into monday as 30.2 inch high pressure builds 
directly over the open waters. 

persistent northerly winds will allow for the development of a band 
of lake effect precipitation thursday through friday. current 
forecast guidance suggests that the band will be positioned 
somewhere from the center to eastern half of the lake, though any 
small changes in prevailing wind direction could result in westward 
shifts. will continue to provide updates in coming forecasts. low 
level temperatures will be supportive for mainly rain, though some 
snow could mix in over the northern half of the lake. thunderstorm & 
waterspout potential is low within the lake effect precip band.
