Will skies be clear over southern Ontario Monday night?
Partly clear skies are likely over regions near and north of Lake Ontario during the evening, except for lots of low-level moisture (illustrated below for mid-evening) that is likely to be visible as occasional cloudiness. Over southwestern regions, cloudy skies are expected due to substantial mid-level moisture (illustrated below for mid-evening) moving eastward over southern Ontario that will cause skies near Lake Ontario to become cloudy later in the evening or after midnight.
