OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
306 AM CDT Sat Mar 23 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...

Currently centered over central Canada, a 30.4 inch high pressure
center will move east toward the Hudson Bay today allowing light and
variable surface flow to turn out of the southeast. A 28.9 inch low
pressure center will form over the central Great Plains on Sunday,
approaching the Upper Mississippi Valley during the day on Monday.
Responding to falling surface pressures regionally, southeast winds
will increase by Monday afternoon. Gusty winds will continue on
Tuesday as the aforementioned low pressure center progresses north
across Lake Superior and drags a cold front across the open waters,
resulting in a west-southwest wind shift. Periods of gale force
gusts are possible Monday and Tuesday, though confidence in
coverage/duration of any such gusts is too low to justify the
issuance of Gale Watches at this time. Will monitor trends over
the coming forecasts, and make any necessary adjustments to
headlines should confidence in gale force gusts increase.
