Will skies be clear over southern Ontario Friday night?

Clearing skies are expected before sunrise over northern parts of southern Ontario as most of the cloudiness with Friday’s cold front moves southeastward overnight. High clouds may be visible in the bright moonlight due to jetstream-level moisture which will be over southern Ontario. Southwestern regions, approximately west of Lake Ontario, will most likely remain cloudy as mid-level moisture remains over that area until later Saturday (illustrated below for 4 am EST).
