open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
236 am cdt thu oct 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...

winds will gradually become easterly tonight as high pressure 
around 30.3 inches slides through the region. the stronger winds 
are expected across the southern half of the lake during this 
time. two areas of low pressure are progged to merge over the 
great lakes region into a single low pressure tonight and deepen 
to around 29.5 inches as it shifts into the eastern great lakes 
through friday. expect a northwesterly wind shift to ramp up and 
increase to gales and nearing storm force at times on the backside
of the departing low pressure while a strong high pressure around
30.7 inches builds to the west. a gale warning is now in effect for
all of the open waters of lake michigan friday morning into 
friday night. 

widespread rain is expected this afternoon into
tonight, with a few thunderstorms possible over the southern open
waters. lake effect showers & thundershowers may linger into
friday along the back side of departing low pressure. a few
waterspouts are possible in the friday showers/thundershowers,
particularly over the southern half of lake michigan.  

as the high sinks toward the ohio river valley on saturday, strong low
pressure around 29.1 inches will develop in northern manitoba. the
tight pressure gradient may bring southwest gales to lake 
michigan on sunday.
