National Weather Service Milwaukee/Sullivan WI
913 PM CDT Sat Jul 13 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...

Southerly winds will continue throughout tonight, shifting
southwesterly into Sunday as low pressure of 29.5 inches develops
in western Ontario and lifts northeastward. A cold front will push
southward through Lake Michigan from this low overnight Monday
into early Tuesday morning, shifting winds to northwesterly.
Breezy conditions linger into Tuesday evening before high pressure
regains prominence.

Thunderstorms are likely this evening, with more widespread
thunderstorms expected late tonight into Sunday morning. A few
storms could be strong to severe, with gusty winds as the primary
hazard. Periods of showers and thunderstorms are forecast later
Sunday and again on Monday along the cold front. A few storms
could be strong to severe within these time frames as well.
