OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
855 PM CDT Sun Jul 7 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 around 30.0 inches over Lake Erie will shift to the
northeast through Monday, resulting in southerly winds across the
open waters. Scattered showers and thunderstorms are anticipated
at times through Monday evening. A cold front will move across the
open waters late Monday into Monday night, resulting in a wind
shift to the west by Tuesday morning.

Later Tuesday night into Wednesday night, there is a potential
for stronger winds over the southern portion of the lake,
depending on the eventual track of the remains of Tropical Storm
Beryl, which may track across central and north central Indiana.
This potential will be updated in later forecasts.
