Will skies be clear over southern Ontario Sunday night?
Mostly cloudy skies are expected, due to high-level moisture which is forecast to move eastward over southern Ontario overnight, except for locations near, north and east of western Lake Ontario where skies may be mostly clear during the early evening before the high-level moisture moisture moves eastward. Some low clouds may cause partly cloudy skies over the regions near western Lake Ontario before the high-level moisture moves over these regions.
