OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
252 AM CDT Tue Apr 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...

Gusty southwest winds will persist today, as low pressure around
29.5 inches moves from Lake Superior to Lake Huron. The low will
bring a cold front southeast through the region today into this
evening. Showers and some thunderstorms are forecast with the
frontal passage.

Expect gusty west winds to turn north later this afternoon into
this evening, from north to south across Lake Michigan. A period
of north gales are expected tonight behind the cold front, and a
Gale Warning has been issued. Building waves are expected as well
tonight.

Winds and waves will gradually lighten up Wednesday into
Thursday, as high pressure around 30.4 inches moves southeast
across the region.

South winds will then increase again Friday and remain gusty into
the upcoming weekend, as multiple low pressure systems move
northeast through the region.
