OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
305 PM CDT Wed Jun 12 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...

Southerly winds will continue across the lake through the
evening, but expect it to increase and turn more west-
southwesterly overnight ahead of an approaching cold front. May
see a few showers and storms with the cold front. Then expect the
front to push across Lake Michigan through the day Thursday with
winds turning more to the northwest behind it later in the day
Thursday. Northerly winds will persist into Friday, but gradually
weaken as high pressure around 30.1 inch builds across the region
through the end of the week. Then as the high pushes out of the
region, expect winds to turn more southerly and increase through
early next week as a very warm and humid airmass pushes into the
region.
