national weather service milwaukee/sullivan wi
859 pm cdt tue apr 28 2026

for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which

gradually shift southeastward into the western great lakes by the 
end of the week. winds will shift to the north northeast tonight,
as a backdoor cold front moves southward across the lake. these
winds should linger into wednesday morning, before weakening in
the afternoon. 

as the high pressure system approaches and moves into the region 
by the end of the week, winds will generally remain light. light 
showers will be possible at times through the rest of the week, as
weak low pressure areas move through.
