OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
254 AM CDT Sun Jun 7 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...

High pressure over the Upper Great Lakes will continue to
strengthen to 30.1 inches today. Warm and humid air lingering
over the relatively cool waters of Lake Michigan will likely cause
marine fog over the north half of Lake Michigan. A Marine Dense
Fog Advisory remains in effect until midday.

Broad low pressure over the Great Plains and high pressure over
the northeastern states will lead to modest southeast winds over
the lake late tonight through Tuesday.

Occasional chances for showers and thunderstorms are in the
forecast, particularly late Monday through Monday night.
Additional chances later in the week.
