OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
251 PM CDT Thu Jul 18 2019

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...

Low pressure around 29.2 inches over northern Ontario and high
pressure over the southeast states will bring a period of elevated
southwest winds to Lake Michigan and rounds of thunderstorms
through Saturday. Then a front will slide down the lake Saturday
afternoon and be the focus for additional thunderstorms. Look for
northerly winds and a dry stretch of weather in the wake of that
system as high pressure of 30.2 builds into the Northern Plains
Sunday and parks over the Great Lakes for the first half of next
week.
