OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
245 AM CDT Wed Jul 17 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...

A few showers will linger over Lake Michigan this morning,
primarily in the north. High pressure of 30.2 inches will slowly
move southward out of central Canada and into the Upper Midwest
tonight. This will end any lingering isolated rain shower chances
and deliver northerly winds and a cooler, drier airmass. This high
will dominate our weather regime into at least the first half of
the upcoming weekend.
