OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
850 AM CDT Sun Mar 24 2019

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 cold front will move through Lake Michigan from the north today.
Expect an increase in wind speeds as the front passes.
Northeasterly gale force winds are expected late this afternoon
through late tonight for the southern two thirds of the lake. High
waves will quickly develop this afternoon and gradually decrease
on Monday.

High pressure of 30.5 inches will move from the northern Plains
into the Great Lakes region for Monday and Tuesday. This will
bring much calmer conditions for the next few days. As this high
shifts to the east a chance for some gusty southerly winds moves
in for Wednesday into Thursday.
