national weather service milwaukee/sullivan wi
909 pm cdt sun apr 26 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

low pressure of 29.4 inches is expected to lift from northeast 
kansas tonight to lake superior by later monday night while
deepening to 29.3 inches. look for increasing easterly winds
tonight and southeast winds through monday night as the low

gales across the lake. winds will shift to the west early tuesday
morning with the cold frontal passage, and gusty westerly winds 
are expected through tuesday afternoon behind the departing low.

high pressure around 30.1 inches will set up over the upper
midwest and upper great lakes tuesday through friday.
