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

.synopsis...a weak ridge of high pressure eases east through this

strong gales, snow squalls, and freezing spray through monday as
arctic air filters back into the region. a cold northwest flow
pattern will dominate much of next week.
