For waters beyond five nautical miles off shore on Lake Huron

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, holds firmly in place
near the Atlantic coast in support of heat and humidity through
Monday. Low pressure, 29.60 inches, then tracks north of Lake
Superior and causes a cold front to settle into the Great Lakes
mid-week which increases shower and thunderstorm chances.
