OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
234 AM CDT Fri Apr 19 2024

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...

Gusty west winds winds are expected today and tomorrow, as low
pressure moves from Ontario into Quebec, and high pressure extends
from the northern High Plains across the middle portion of the
country. The westerly winds will become lighter on Sunday as a
surface ridge approaches from the west, and then will turn
southwesterly early next workweek.
