Will skies be clear over southern Ontario Wednesday night?

It looks like skies will most likely be clear over southern parts of southern Ontario during the first several hours after sunset, and then become mostly cloudy by about mid-evening. Elsewhere, skies are likely to be cloudy by evening. 

Clear skies following Wednesday afternoon’s cold front will be followed by increasing low and mid-level moisture which is forecast to move eastward across southern Ontario during early evening (illustrated below at EST 19:00) and the moisture is likely to cause skies to become mostly cloudy over most or all regions by about mid-evening.
