OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
301 PM CDT Thu Oct 10 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...

High pressure of 30.3 inches will gradually slide southeast over
the Great Lakes through Friday morning. Winds will become
southwesterly and breezy tonight into early Friday as a low
pressure based in the Hudson Bay area of 29.6 inches slides east.
The associated cold front sliding west will drop down the long
axis of Lake Michigan late Friday afternoon and evening. Winds
will abruptly change to northerly behind the cold front and remain
breezy into early Saturday morning. Look for easterly winds to
develop as weak low pressure of 29.8 inches builds into the
southwestern Great Lakes region Saturday.

This developing low pressure of 27.7 inches as it pushes across
the southern Great Lakes Saturday night will then deepen as it
tracks across the northeast US on Sunday. The degree of deepening
is still uncertain. This will result in gusty northerly winds
over Lake Michigan Sunday afternoon and night, and there is an
increasing chance of low- end gales.
