FZUS63 KMKX 280820 GLFLM OPEN LAKE FORECAST for Lake Michigan National Weather Service Milwaukee/Sullivan WI 320 AM CDT Mon Sep 28 2020 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... Behind this morning's cold front, westerly winds will shift to the northwest and increase through the afternoon and continue overnight. Then modest westerly winds will return Tuesday and last into Wednesday, before another strong cold front makes its way through the region. This will bring brisk north to northwesterly winds across the open waters of Lake Michigan later on Wednesday into Friday. Gales are not expected, but higher waves will be possible at times. Additionally, with the colder air moving over the warmer lake waters, there looks to be a potential for waterspouts for later half of this week. && LMZ261-362-364-366-563-565-567-868-281530- Lake Michigan from Seul Choix Point to Rock Island Passage 5 NM offshore to Mid Lake- Lake Michigan South of a line from Seul Choix Point to the Mackinac Bridge and north of a line from Charlevoix MI to South Fox Island 5 NM offshore- Lake Michigan from Charlevoix to Point Betsie MI 5 NM offshore to Mid Lake- Lake Michigan from Point Betsie to Manistee MI 5 NM offshore to Mid Lake- Lake Michigan from Rock Island Passage to Sturgeon Bay WI- Lake Michigan from Sturgeon Bay to Two Rivers WI 5 NM offshore to Mid Lake- Lake Michigan from Two Rivers to Sheboygan WI 5 NM offshore to Mid Lake- Lake Michigan from Pentwater to Manistee MI 5 NM offshore to Mid Lake- 320 AM CDT Mon Sep 28 2020 SHEBOYGAN WI TO PENTWATER MI NORTH... .TODAY...West winds 10 to 15 kt veering to north 10 to 20 kt.
