Lake St Clair Forecast
National Weather Service Detroit/Pontiac MI
Issued by National Weather Service Gaylord MI
935 PM EDT Tue Jun 3 2025

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...Broad area of high pressure, 30.21 inches, has
nestled into place on the Mid Atlantic coast. Meanwhile, 29.56
inch low pressure is moving northeast through Wisconsin into the
Straits of Mackinac and St. Mary`s River valley, with an attendant
cold frontal boundary stretching all the way south and west to
Texas. This area of lower pressure will lead to continuity of an
already pinched pressure gradient, and thus, keeping SW flow
elevated all the way through Wednesday into Wednesday evening as
the aforementioned cold front slowly advances south and east
through the Great Lakes. Current showers generally over Lake
Michigan and Lake Superior (stretching south into northern lower
Michigan) will continue their south and eastward advance tonight
into Wednesday. Showers and (eventually) thunderstorms will build
later in the day Wednesday, especially in the afternoon and
evening, with chances for stronger to severe storms. The front
clears late Wednesday evening before stalling over northern Ohio
on Thursday, leaving potential for some residual showers through
the day on Thursday.
