OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
240 AM CDT Thu Sep 19 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...

Light winds and increasing humidity may lead to patchy fog across
the northern third of the lake early this morning. High pressure
around 30.2 inches over New England will gradually weaken and
drift east today, with low pressure over the Plains strengthening
to 29.2 inches. This will produce south- southeast winds into
Friday. A weak front will push southeastward across the open
waters tonight into Friday, bringing showers and isolated
thunderstorms. Drier conditions are expected Friday night through
Saturday before another area of low pressure around 29.6 inches
begins to push into the Great Lakes region early next week, with
winds becoming generally easterly ahead of this system. As low
pressure approaches, additional shower and thunderstorm chances
develop. More westerly winds are expected behind the system.
