National Weather Service Milwaukee/Sullivan WI
256 AM CDT Sun May 5 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...

High pressure of 30.1 inches will spread into the Upper Great
Lakes Region and linger through Monday. This high pressure will
bring light northerlies to the lake this morning, with winds
growing light and variable over the lake this afternoon into
tonight. Monday, winds look to become easterly at times, but lack
of a strong pressure gradient over the area will mean that the
east winds will be interspersed with boughts of light and variable
conditions.

Monday night, winds will grow southeasterly and breezy to 20 knots
over the southern half of Lake Michigan by Tuesday morning. Winds
then come around to westerly after a front lifts north over the
area Tuesday night into early Wednesday morning.
