OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
303 AM CDT Mon Jul 1 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...

Weak winds early this morning will be light and variable across
the northern half of the lake while the southern half will have
predominately light easterly winds. The lighter winds through mid
morning will be due to high pressure around 30.3 inches moving
overhead. High pressure will continue moving east until it exits
the western Great Lakes Region Monday night. Winds will become
southeasterly and increase as low pressure around 29.4 inches
moves northeast from Saskatchewan toward James Bay. Winds will
remain south to southeasterly until Tuesday night when a cold
front crosses the lake. Rain and thunderstorms are expected with
the frontal passage. Southwest to west winds are expected behind
the front. Weak high pressure returns to the region Wednesday
night into Thursday bringing a return of light and variable winds.
