National Weather Service Milwaukee/Sullivan WI
857 PM CST Sat Dec 3 2022

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

As high pressure moves east across the Ohio River Valley and a
29.6 inch low passes to the north of Lake Superior, expect
southwest winds to steadily increase late tonight through Sunday
night. Southwest gales are expected over the northern portions of
the lake Sunday night, and a Gale Warning is in effect for that
period.

Lighter winds are expected Monday, with a passing cold front
shifting winds to the northwest for Monday night. Winds should
generally be light to moderate into the middle of next week.
