Will skies be clear over southern Ontario Wednesday night?

Skies are likely to be partly clear with some low clouds during the early evening over most regions, except for more cloudiness over regions south and east of Lake Huron and Georgian Bay. Then, increasing mid-level cloudiness is expected by mid or late evening, due to increasing mid-level moisture which is forecast to move eastward over southern Ontario overnight (illustrated below for mid-evening) ahead of Thursday’s low pressure trough.
