Will skies be clear over southern Ontario Wednesday night?

Clear skies are expected over most regions, except for some low-level clouds near western Lake Ontario during the evening until a region of low-level moisture moves southward from southern Ontario overnight (illustrated below for late evening). Some thin jetstream-level clouds might also be visible from time to time (due to the jetstream extending west-to-east across southern Ontario), and some low-level clouds are likely to develop south of Lake Huron before morning.
