OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
857 AM CST Sat Jan 22 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

A low pressure trough of 29.7 inches will swing through north of
the Great Lakes today, dragging a cold front through the area. High
pressure of 30.3 inches just west of Wisconsin will then drop
southward through the region on Sunday, with breezy north to west
winds likely across the lake. Winds will continue to be breezy at
times through early next week as another low moves through the
region.

Freezing spray will remain at risk at times this weekend into
next week, due to the cold temperatures and elevated winds and
waves.
