Open Lake Forecast for Lake Huron
National Weather Service Detroit/Pontiac MI
331 AM EST Thu Nov 23 2017

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...A ridge of high pressure...30.00 inches...will maintain
a grip on the region as the center of surface high pressure becomes
increasingly centered over the eastern United States. A weak cold
front will settle into the northern Great Lakes today before
stalling out. The next low pressure system, 29.10 inches, will
rapidly advance out of the Canadian Prairie provinces this evening,
before tracking directly across portions of Ontario on Friday. A
cold front will push across the region early Saturday, with a brief
surface ridge building into the state early Sunday.
