OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
855 PM CDT Wed Apr 24 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 winds generally from the southeast will prevail over Lake
Michigan tonight through Thursday as high pressure of 30.3 inches
continues to influence the Great Lakes region. Low pressure of
29.1 inches will develop across the Great Plains on Friday and
move northeast towards Lake Superior by Saturday afternoon. Strong
southeast winds will develop across the lake on Friday as this
low moves north, and will through the day on Saturday with wave
heights approaching 9-10 ft. Gales are possible Friday night
through Saturday, but uncertainty remains given stability in the
low levels of the atmosphere.

Another area of low pressure will move across the Great Lakes
region Sunday and Monday which will again bring breezy south
winds across Lake Michigan. The second low will move north of the
Great Lakes Monday and Tuesday allowing for winds to become
westerly. Showers and thunderstorms are likely across the lake
this weekend as the low pressure areas move through the region.
