Will skies be clear over southern Ontario Wednesday night?

Skies will most likely be cloudy except that skies may be partly clear during the early evening over eastern regions of southern Ontario (generally near Lake Ontario and GTHA) where some mid-level clouds (remaining after possible showers and thunderstorms that may develop during the afternoon) and some clear sky may be visible, until more substantial mid-level moisture (illustrated below for late evening) moves eastward over southern Ontario and causes skies to be mostly cloudy overnight.
