OPEN LAKE FORECAST for Lake Michigan National Weather Service Milwaukee/Sullivan WI 258 PM CDT Sat Apr 27 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 29.5 inches over Lake Superior will continue to gradually weaken as it moves into Ontario this evening. Gusty south winds are expected across Lake Michigan this afternoon, with a few gusts approaching or reaching gale force, especially in the northeast portion of the lake. Areas of dense fog may redevelop this evening over the northern portion of the lake as the winds become lighter, while dense fog may form over the southern portion of the lake late tonight into Sunday.
Winds will then gradually shift from southwest to northerly tonight as a cold front tracks south, 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 tonight into Monday morning. A few of these storms could produce locally gusty winds and hail.
