OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
246 PM CDT Sun Jun 30 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 north winds continue over the southern half of the lake this
evening. Winds will weaken tonight into Monday and become
predominately easterly (light and variable further north) as high
pressure around 30.3 inches builds in from the Northern Plains.
High pressure will advect east of the Lake Monday night, causing
winds to become southeasterly and increase. South to southeast
winds will linger into Tuesday night, before a cold front moves
east across the region. Behind the cold front, southwest to west
winds gradually decelerate throughout the day Wednesday. Weak high
pressure passing over the lake Thursday will lead to light and
variable winds.
