Will skies be clear over southern Ontario Friday night?

Increasing high cloudiness, due to jetstream-level moisture that is forecast to move eastward across southern Ontario overnight (illustrated below) will cause skies to appear partly or mostly cloudy, except for some periods with less cloudiness when the appearance of the brighter stars and moon may give the impression of clear skies (especially from urban areas where the fainter stars are not visible). Smoke from western wildfires moving across southern Ontario during Friday may also reduce the clarity of the skies if some stars are visible.
