OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
822 PM CST Wed Feb 26 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...

Low pressure of 29.6 inches will continue to lift northeast from
Pennsylvania will strengthen 29.2 inches by the time it reaches
Lake Ontario early Thursday. Breezy north to northwest winds are
expected across Lake Michigan between the low to the east and high
pressure to the west. The trends in winds suggest the Gale Warning
for just the southern third of the lake will be allowed to expire
at midnight.

Northwest winds will remain elevated Thursday as the low slowly
lifts northward. Northwest winds will become breezy over the
northern third of the lake possibly bringing some gales into Thursday
afternoon and evening. Thus a Gale Watch is in effect for this
period. Winds will however weaken into Friday and weaken further
into Saturday

Still looks like freezing spray chances continue through Thursday
night.
