Will skies be clear over southern Ontario Tuesday night?

Mostly clear skies are likely, except for some cloudiness during the evening over regions near and north of lake Ontario, caused by some low and mid-level moisture which is gradually moving eastward from southern Ontario during Tuesday (illustrated below for late evening) and except for increasing cloudiness after midnight over most regions, caused by increasing mid-level moisture which is forecast to move southward over southern Ontario early Wednesday (illustrated below for early Wednesday).
