OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
301 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...

Low pressure around 29.3 inches across far northwestern Ontario
will drag a weak cold front across Lake Michigan through the
morning. Winds will turn more west-southwest behind it and pick
up through the afternoon with gusts to around 20-25 knots. Then 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 the evening as low pressure treks across the Upper
Mississippi River Valley and deepens to around 29.6 inches over WI
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 more
northwesterly winds behind it to gradually weaken through Saturday
evening.
