National Weather Service Milwaukee/Sullivan WI
843 AM CDT Sat Jun 14 2025

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 30.3 inches along the Ontario and Quebec
border will keep winds primarily easterly to northeasterly through
the most of the weekend. Weak low pressure around 29.9 inches in
southern Illinois will push east today, moving into the Ohio
River Valley and weakening into Sunday. Chances for showers and
thunderstorms are forecast at times Monday into next week, as the
Ontario high pressure system weakens and low pressure approaches
the region from the Central Plains.
