National Weather Service Milwaukee/Sullivan WI
853 AM CDT Sat Apr 20 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...

High pressure of 30.3 inches over the central US and deepening
low pressure of 29.1 inches across northern Quebec will maintain
west winds over Lake Michigan today. Winds will gradually decrease
in intensity through the day, with lighter winds expected into
Sunday as high pressure approaches from the west. Light and
variable winds will then occur with the passage of the high Sunday
night. Breezy south winds will then develop for Monday into
Tuesday as low pressure approaches the northern Great Lakes from
Canada. Winds could approach gale force during this time.
