Will skies be clear over southern Ontario Wednesday night?
It looks like mostly clear skies are expected during the evening, especially over southern regions of southern Ontario, while partly cloudy skies are expected further north, closer to a large region of mid-level moisture forecast to be over the Lake Huron region, ahead of a low pressure trough developing west of the Great Lakes region. The chart below shows one forecast model's depiction of mid-level moisture that will likely cause mid-level cloudiness to be visible over some parts of southern Ontario during the evening.
