Will skies be clear over southern Ontario Thursday night?

It looks like skies will be gradually clearing during the evening as extensive afternoon cloudiness dissipates, but conditions are suitable for cool upper-level air flowing across the relatively warm water surfaces of Lake Huron and Georgian Bay to create low-level cloudiness and transport it eastward across southern Ontario. So, some periods of cloudiness can be expected throughout the night in regions east of Lake Huron while mostly clear skies are likely in southwestern regions south of Lake Huron.
