Will skies be clear over southern Ontario Wednesday night?

Partly clearing skies are likely over many regions later in the evening as mid-level moisture moves south and east of the province (illustrated below for mid-evening), but a strong jetstream will be over southern Ontario and jetstream-level moisture will be causing high cloud to cover the sky. Bright moonlight will likely become visible over most regions overnight, and may give the impression of clear skies in locations where the high cloud is not obvious and visible.
