Will skies be clear Tuesday night over southern Ontario?

Skies are likely to be mostly cloudy during early evening over most regions, due to low-level moisture flowing across southern Ontario regions south and east of Lake Huron and Georgian Bay (illustrated below for late evening) and passage of a cold front, but there will most likely be clear skies over various regions from time to time and after about midnight, especially toward morning as the cold front (causing the uplift and cloudiness) moves south of Ontario.
