####018006228#### FZUS63 KMKX 101411 GLFLM OPEN LAKE FORECAST for Lake Michigan National Weather Service Milwaukee/Sullivan WI 911 AM CDT Wed Apr 10 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 to moderate southwest to southerly winds wind will persist today into this evening as weak high pressure around 29.9 inches is pushed east by an area of low pressure around 29.7 inches tracking from northern Minnesota to Lake Superior. Winds will increase and turn more east-northeasterly heading into Thursday as a stronger low pressure deepens to around 29.0 inches as it lifts across the lower Mississippi and Ohio River Valleys. With the strong pressure gradient, expect gusts up to around 30 knots, but cannot rule out a few gale force gusts on Thursday. The low pressure continues to deepen to around 28.9 inches as it lifts across IN into lower MI through Thursday night. Widespread gusts exceeding 30 knots are expected on the backside of the departing low and while there remains some uncertainty, there is a potential for gales through the day Friday. Will continue to monitor trends for stronger northwesterly winds/gales on Friday to assess marine headlines. Otherwise, the low lifts across eastern Ontario and Quebec later Friday and into Saturday and winds weaken across Lake Michigan for the weekend.
