National Weather Service Milwaukee/Sullivan WI
240 AM CDT Wed May 8 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...

Low pressure of 29.4 inches over the northern end of Lake Michigan
will exit east toward Lake Ontario through today. Light to
moderate northwesterlies over the northern end of the Lake to
southwesterlies over the south end of the lake will persist until
about mid-day, when a weak trough attached to the low moves from
north to south over the lake. Winds behind this trough will come
around to northerly and finally northeasterly by the late
afternoon to early evening. Northeasterlies will then continue
overnight into Thursday as an area of low pressure passes east
over the Ohio River Valley. Gusts to 25 knots may occur over the
south half of the lake late Thursday morning into Thursday
afternoon.

Winds then ease Thursday night as high pressure of 30.0 inches
approaches the Upper Great Lakes.
