Will skies be clear over southern Ontario Thursday night?

It looks like some clearing skies are likely over some parts of southern Ontario by sunset, due to mid-level moisture moving eastward from southern Ontario during the afternoon, but a high-level jetstream directly over southern Ontario will most likely cause some high-level cloud to be visible.  Fog is likely to develop, especially in regions where skies become clear, and high dewpoint and humidity at ground level will cause any unprotected optical surfaces exposed to the sky, to become dew-covered.
