OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
311 PM CDT Sun Mar 24 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...

High pressure around 30.4 inches continues to track east across
Quebec while a low pressure around 28.9 inches develops over the
Central Plains. Expect southeasterly winds to continue to
increase through the evening as the low gradually slides into the
Midwest on Monday. Will continue to see stronger southeasterly
winds through the day Monday across Lake Michigan. While we cannot
rule out a few brief gusts approaching gale force over Lake
Michigan at times on Monday, the better potential to see stronger
winds to gales will be when the low tracks across IA and into WI
Tuesday. This will drag a cold front across the region and turn
southeasterly winds back to the west Tuesday evening. May also see
a few thunderstorms across souther portions of the lake ahead of
the cold front. Otherwise, stronger winds look to linger through
the evening but are progged to weaken a bit heading into Wednesday
as the low pressure lifts into the Hudson Bay region and high
pressure builds across the Upper Mississippi River Valley. Can
expect breezy winds through the second half of the week as the
high pressure works its way into the Ohio River Valley.
