Lake St Clair Forecast
National Weather Service Detroit/Pontiac MI
341 PM EST Thu Feb 20 2020

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 broad strong high pressure system, averaging 30.80
inches, will continue its slow southeastward track across the
Plains into the mid- Mississippi valley the remainder of this
week. The central Great Lakes region will remain on the eastern
and northern edges of the high during this time. A low, 29.10
inches, pivoting through the Hudson Bay Friday sets up a stronger
gradient over the Great Lakes region. Long fetch with southwest
flow creates the possibility of low-end gale-force gusts over
Outer Saginaw Bay and central Lake Huron warranting a Gale Watch
Friday afternoon into early Saturday morning.
