southwest Monday as low pressure around 29.7 inches moves across
Ontario. Southwest winds remain through Monday night as high

before a trailing cold front from the Ontario low pushes across
the lake Tuesday morning. Modest west to northwest winds are
expected behind the front and will persist into the middle of the
week.
