Lake St Clair Forecast
National Weather Service Detroit/Pontiac MI
357 PM EST Mon Jan 30 2023

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
West to west northwest winds over the lakes today with
a high pressure, 30.60 inches, across the plains. Arctic air is
also moving into the region this afternoon resulting in elevated
winds up to 25 knots. Winds in combination with the arctic air
will bring moderate freezing spray this evening and tonight.
Lighter winds for Tuesday morning and afternoon before west-
southwesterly winds increase Tuesday night and remain elevated
through mid-week. A low pressure, 29.50 inches, moving over
Quebec will help drag a reinforcing shot of cold air into the
region Thursday into Friday. The result will be a round of
possible gales along with more widespread moderate to heavy
freezing spray across Lake Huron.
