Will skies be clear over southern Ontario Saturday night?

Mostly cloudy skies are expected except for partly clear skies over the GTHA and western Lake Ontario areas during early evening, but high cloudiness is likely to be over those regions by sunset, caused by high-level moisture (illustrated below for early evening). Then, thicker, mid–level cloudiness is expected later during the evening, caused by mid-level moisture which is forecast to be over most regions by late evening (illustrated below for late evening).
