Lake St Clair Forecast
National Weather Service Detroit/Pontiac MI
350 PM EDT Thu Apr 9 2026

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...Surface low pressure exits into James Bay while its
cold front stalls over the southern Great Lakes. Briefly dry
conditions give way to additional opportunities for showers and
perhaps a couple thunderstorms tonight and Friday as an upper
level disturbance from the High Plains moves into the Great
Lakes. Some light snowfall is possible for the north/central
Huron basin. High pressure then builds out of the Upper Midwest
to start the weekend with drier and calmer conditions. Active
weather will be possible again Sunday through Tuesday due to
several passing disturbances.
