national weather service milwaukee/sullivan wi
858 pm cdt tue mar 21 2023

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...

a weak boundary will continue to lift northward across the lake
tonight, as low pressure around 29.7 inches moves from the 
central plains to the arrowhead region of minnesota. winds will 
become south to southeast and modestly breezy behind the 
boundary. 

modest south winds should then continue until wednesday night, 
when a cold front is expected to move southeast over the lake, 
changing winds to a northwest direction. north winds are then 
expected behind front on thursday, becoming northeast on friday.
