National Weather Service Milwaukee/Sullivan WI
837 PM CDT Fri May 17 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 will continue tonight under the western edge of high
pressure of 30.0 inches centered over the eastern United States.
Southerly winds will pick up a bit on Saturday ahead of an
approaching trough of low pressure. Winds will switch to northerly
on Sunday behind the trough, as high pressure of 30.0 inches moves
back into the area. Breezy southerly winds will return to the area
for Monday and Tuesday ahead of the next approaching low pressure
system.

Areas of fog will likely continue across roughly the southern half
of the lake tonight, winding down Saturday morning. Will continue to
monitor satellite trends to determine if the current advisory will
need to be extended past 09Z tonight.
