OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
303 AM CST Fri Feb 28 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...

High pressure of 30.3 inches centered just north of Minnesota
early this morning will slide southward today, reaching the MN/IA
border by this evening. The high will then head south southeast to
southern IL by Sat morning. Northwest winds will remain brisk
today between the approaching high and low pressure well to the
southeast. Though winds look borderline, will keep the Gale
Warning going for northern Lake Michigan, as it still looks like
gusts to 35 knots will be possible at times.

Winds will be lighter Saturday under more of an influence from
the high. Winds will pick up a bit early next week, but gusts are
expected to generally remain below 25 knots.
