National Weather Service Milwaukee/Sullivan WI
308 AM CDT Wed May 29 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

occasionally be encountered.

.SYNOPSIS...

A broad area of low pressure around 29.9 inches continues to
slide east today. Expect breezy northerly winds on the backside of
the departing low pressure to extend across Lake Michigan today
with gust up to around 20-25 knots, especially across the southern
half through the afternoon. Then winds will weaken overnight into
Thursday as high pressure around 30.2 inches works it way over
Lake Michigan through Friday. Lighter and variable winds will
persist during this time before picking up later Friday into the
weekend as the high pressure slides east and low pressure deepens
across central Canada. Periods of showers and thunderstorms will
return from Friday night through the beginning of next week.
