OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
924 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...

A stalled front is draped across the southern end of the lake
today. Low pressure around 29.8 inches will track from Missouri to
Iowa today while strengthening to 29.6 inches, and then into
northwest Wisconsin Monday morning. The front over southern Lake
Michigan will lift into the Upper Peninsula by Monday morning. Thus,
north to northeast winds are expected across the majority of Lake
Michigan today, with the highest winds (up to 30 kts) over
central Lake Michigan. Expecting light and variable winds over the
southern third of the lake (near the stalled front) and south
winds at the far southern tip of the lake.

Modest east to southeast winds will then develop over all of the
lake tonight 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 tonight into Monday morning. Breezy
south winds will develop over the remainder of the lake on Monday.

Areas of fog may form over the lake today, especially the southern
half. Several rounds of showers and thunderstorms are expected
between now and Monday.
