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...

Modest southerly winds will prevail through tonight. Low pressure
around 29.5 inches lifting from the northern Plains into
northwestern Ontario on Tuesday will then produce gusty southerly
winds Tuesday through Tuesday night. Light southwesterly winds are
then expected as the low continues to lift into the Hudson Bay, with
a cold front slowly pushing southward across the lake Wednesday
night into Thursday, shifting winds northeasterly.

Periods of thunderstorms are expected to continue this afternoon
through this evening, with slight chances on Tuesday morning.
Slight chances are expected again Tuesday afternoon (mainly across
the southern half). Thunderstorms become more likely on Wednesday
into Wednesday night across the open waters as the cold front
enters the region.
