Will skies be clear over southern Ontario Tuesday night?

It looks like very clear skies are likely, with a strong high pressure ridge overhead. Some locations near western Lake Ontario might be prone to low-level stratus clouds drifting toward the west, under northeasterly winds (at noon Tuesday) becoming southwesterly Tuesday evening. The stratus clouds are visible on visible satellite imagery (such as the example below) and may move northward over the regions around the western end of Lake Ontario (generally the GTHA regions) as low-level winds become southeasterly during Tuesday evening.
