national weather service milwaukee/sullivan wi
309 am cst fri jan 22 2021

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

occasionally be encountered.

.synopsis... 

the gusty northwest winds continue through today before weakening
tonight as high pressure of 30.1 inches passes to the south of 
lake michigan. as this pushes out saturday expect light southerly
winds across the lake that will strengthen some as weak low
pressure across the southern central plains around 29.8 in pushes
in, however winds are expected to remain rather modest across the
lake. winds will then turn northerly as this system pushes out 
sunday.
