Will skies be clear over southern Ontario Sunday night?
Clear skies are likely during the evening over most regions, except for some mid-level clouds over eastern regions of southern Ontario (approximately north, south and east of GTHA) until mid-level moisture (illustrated below for late evening) moves south of the province. After midnight, mostly clear skies are expected except for high thin clouds that may appear when jetstream-level moisture moves eastward over southern Ontario (illustrated below for early morning).
