053 FZUS63 KMKX 260754 GLFLM OPEN LAKE FORECAST for Lake Michigan National Weather Service Milwaukee/Sullivan WI 254 AM CDT Sun May 26 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... High pressure of 29.9 inches over Lower Michigan will move east into New England today, while low pressure of 29.4 inches lifts from Kansas into western Illinois by this afternoon, and then to southern Lake Michigan by late tonight. This will result in increasing southeast to east winds across the lake for today, with showers and thunderstorms likely at times today, largely for the southern portion of the lake. That low will then progress northeastward to Lake Huron by Monday afternoon, with winds quickly turning northwesterly as the low departs. West to northwest flow will persist into mid week, with winds gradually weakening over time as high pressure eventually builds into the region.
