Will skies be clear over southern Ontario Saturday night?
Cloudy skies are expected except for partly clear skies over eastern regions of southern Ontario during early evening, in locations where thunderstorms don't develop, and where cloud cover remains thin enough to allow the brighter stars and planets to be visible and cause the appearance of partly clear skies. By mid-evening, increasing mid-level moisture is forecast to move eastward over all of southern Ontario (illustrated below for shortly before sunset) and cause skies to become cloudy.
