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...Low pressure, 29.30 inches, will track southeast
across southouthern Ontario overnight delivering a potent cold
front and strong winds. The arctic airmass may also favor the
development of snow squalls, especially late this evening before
the colder air lingers into Saturday. High pressure eventually
builds in on either side of the central waterways over the
weekend.
