Will skies be clear over southern Ontario Monday night?

Skies could become partly clear for several hours after sunset over some regions, before widespread cloudiness moves over southern Ontario later in the evening. However, the break in cloudiness after sunset will most likely have some mid-to-high level cloudiness present (illustrated below for high-level moisture at the 500 hPa level) but skies may be clear enough for brighter stars and the waning gibbous moon to be visible and potentially give the impression of clear skies.
