Will skies be clear Monday night over southern Ontario?
It looks like mostly clear skies are likely over most regions. Some high-level cirrus over southern Ontario during the afternoon is forecast to diminish by evening, and some mid-level cloudiness over some regions during Monday is likely to dissipate after sunset (as the lifting motions that sustain the clouds diminishes). Any remaining mid-level cloudiness is more likely to be generally north of or east of the Toronto area during the evening, as seen on the chart for mid-level moisture below.
