OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
324 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 strong cold front over northern Lake Superior into far northern
Minnesota will move south across Lake Michigan today. Gusty north
to northeast winds are expected with the frontal passage,
including gale force winds from late this afternoon into late
tonight over the southern two thirds of the lake. High waves will
quickly build this afternoon and continue into Monday.

Quiet weather conditions are then expected Monday into Tuesday, as
high pressure of 30.5 inches moves from the northern Plains into
the central Great Lakes region. Warmer air moving into the region
Wednesday into Thursday night will bring the next chance for
gusty southerly winds over Lake Michigan.
