OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
324 AM CDT Mon Jun 16 2025

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 around 30.2 inches, now over the Atlantic will
with low pressure around 29.8 inches over the northern plains has
allowed for winds to turn southerly today. Winds will turn
increasingly breezy particularly on the north side of the lake
this evening into Tuesday as the low pressure, now around 29.5
inches, crosses the northern Great Lakes region, bringing chances
for thunderstorms. Another low pressure around 29.5 inches
approaches from the central Great Plains on Wednesday, with
continued thunderstorm chances. The exact trajectory of this low
will determine Wednesday`s wind field, but for now the best guess
is southerly winds for the south half and easterly winds for the
north half of the lake.
