Will skies be clear Wednesday evening over southern Ontario?

It looks like some low clouds during the early evening will dissipate and disappear within several hours after sunset over most regions, except for more persistent low-level cloudiness near western Lake Ontario. Other than the lingering low-level moisture near Lake Erie and western Lake Ontario, the flow of dry and clear air from the north-northeast will provide clear skies over most regions. Some jetstream-level moisture is forecast to move over southwestern Ontario overnight but probably won’t cause any visible high cloudiness.

The chart below shows the forecast amount of humidity at the level of low clouds at UTC 24:00 but by the end of twilight, low clouds may have disappeared over most locations (except near western Lake Ontario).
