Waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. Occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.SYNOPSIS...High pressure, 30.20 inches, will center over the
Great Lakes Thursday morning, bringing light winds and dry
weather. High pressure will then wash out across New England
Friday as a low pressure system strengthens and moves into
western Ontario. This will push a warm front across the Great
Lakes, veering winds to the south, with wind speeds increasing in
the wake of the front.
