open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
252 am cdt mon apr 27 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...

low pressure of 29.5 inches over eastern kansas will lift into 
lake superior by late tonight while deepening to 29.3 inches.
southeasterly winds will increase throughout today to gust around
30 kt throughout the afternoon and early overnight hours. although
the cooler lake temps should dampen the threat for widespread gales
across the lake, thunderstorms during the afternoon and evening
may produce multiple periods of gale force gusts in the southern
half. trends will be monitored into the afternoon regarding the 
wind threat within the storms and regarding potential for gales 
outside of these storms. winds will shift to the west early 
tuesday morning with the cold frontal passage from this exiting 
low, and gusty westerly winds are then expected through tuesday 
afternoon.

high pressure around 30.1 inches will set up over the upper
midwest and upper great lakes tuesday through friday, producing
light and variable winds.
