OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
845 AM CDT Wed Jul 3 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...

A weak cold front across the southern third of the lake will
continue to progress southward, with west-southwest winds
increasing through the day. Gusts around 25 kt are expected
during the afternoon hours. A weak area of high pressure around
29.9 inches over the Central Plains this morning will gradually
slide into the area this evening, easing the west-southwesterly
winds this evening into the start of Thursday/Independence Day.
Winds will gradually increase through Thursday evening as low
pressure treks across the Upper Mississippi River Valley and
deepens to around 29.6 inches over Wisconsin overnight into
Friday. Expect northeast-east winds across the northern half of
the lake and more west-southwest winds across southern portions as
the low pressure system tracks across the middle section of Lake
Michigan Friday evening/night. As low pressure lifts into eastern
Ontario/Quebec Saturday, expect northwesterly winds behind it to
gradually weaken through Saturday evening.
