1/3 of the wave spectrum. Occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.SYNOPSIS...Low pressure will continue to deepen to around 29.5
inches as it passes over the northern half of Lake Huron
overnight. As the low tracks northeast and exits into Canada.
Southwest winds increase behind the departing low late tonight,
then gradually relax by mid morning Friday. A cold front drops
south across the central Great Lakes on Friday, bringing with it
winds from the north and northeast. High pressure building into
the region from the Upper Mississippi Valley over the weekend
will keep north and northeast winds locked in through much of the
weekend.
