Will skies be clear over southern Ontario Saturday night?
It looks like mostly clear skies are likely by sunset, except for some mid-level cloudiness during the evening mainly near and west of the GTA and western Lake Ontario. The forecast chart below (if it loads onto the blog without complications) shows the location of the mid-level moisture during the evening. Uplift ahead of an upper level trough (moving eastward across southern Ontario overnight) will cause the moisture to form some cloudiness.
