Will skies be clear Sunday evening over southern Ontario?
It looks like skies will be mostly clear during the evening, except for jetstream-level moisture which is forecast to move northeastward across southern Ontario ahead of a warm front after sunset and may be visible as high clouds. Later in the evening, mid-level moisture and cloudiness is forecast to move over southern Ontario and may not cause noticeable widespread cloudiness until after midnight over eastern regions of southern Ontario (such as east of the Toronto area).
