Lake St Clair Forecast
National Weather Service Detroit/Pontiac MI
312 PM EDT Sun May 19 2019

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...Low pressure, 29.50 inches, will travel northeast from
Lake Michigan into the Georgian Bay throughout the day which will
allow south to southwesterly flow up to 20 knots to persist this
afternoon and evening. The passage of the low pressure system
will allow a cold front to drag through the Great Lakes tonight
before a high pressure system, 30.20 inches, settles in across
Michigan by Tuesday morning. High pressure will then maintain its
strength and will gradually shift east, centering over eastern
Ontario/western Quebec by Wednesday morning.
