OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
1215 AM CDT Sun Apr 28 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...

Low pressure around 29.7 inches northeast of Lake Superior will
continue to gradually weaken as it moves into Quebec later
tonight. Its cold front will gradually shift the winds from
west southwest to northerly late tonight, but southerly winds
will continue over far southern Lake Michigan as the front stalls.
Brisk northeast winds will then prevail over central Lake
Michigan on Sunday with lighter winds in the north, and variable
winds in the south where the stalled front remains.

Modest east to southeast winds will then develop over all of the
lake Sunday night as the stalled front moves north as a warm
front. Brisk east winds, possibly reaching gale force, are
expected over the northern tip of the lake late Sunday night into
Monday morning. Breezy south winds will develop over the remainder
of the lake on Monday.

Rounds of showers and thunderstorms are expected overnight,
continuing today through Monday.
