National Weather Service Detroit/Pontiac MI
Issued by National Weather Service Grand Rapids MI

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 this morning, bringing light winds and dry weather.

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.
